## The Challenge: Simplifying Web3 for Mainstream Mobile App Users

Like many applications venturing into the web3 space, Kropot faced significant hurdles in making Web3 intuitive for a broad mobile audience. The primary challenges included:

- **Complex Wallet Onboarding:** Traditional Web3 wallet creation processes, often involving the secure management of seed phrases, presented a steep learning curve and a point of friction for everyday mobile users unfamiliar with blockchain technology.
- **Transaction Complexity and Costs:** Requiring users to understand and manage gas fees for blockchain transactions added another layer of complexity, potentially deterring engagement and frequent use of Web3 features within the mobile app.
- **Maintaining a Smooth User Experience:** Integrating powerful Web3 functionalities without disrupting the intuitive, native feel of a mobile application was crucial. Kropot needed to avoid a fragmented experience that could arise from redirecting users to external wallet applications or cumbersome interfaces.

How Kroma Team Build Kropot, a Reward Mobile App


> "Openfort has been transformative for our ecosystem. We've eliminated the traditional barriers of Web3 while preserving true asset ownership, allowing everyday users to effortlessly participate in our decentralized computing network." — Gaimin team

## The Challenge: Complex web3 onboarding creating barriers for DePIN adoption

[Gaimin](https://gaimin.io) operates a pioneering decentralized physical infrastructure network (DePIN) that enables users to monetize their idle PC power through the gaimin.gg platform. Their network harnesses unused computing resources to power AI processing and file-sharing services for businesses and individuals. However, their ambitious vision of building a widely-accessible decentralized computing network faced significant technical barriers.

"Before implementing Openfort, our DePIN participants experienced multiple friction points that hampered network growth," explains the Gaimin team. "They were forced to redirect to third-party Web3 wallets, navigate complex wallet setup processes, and manage cryptic private keys—all substantial barriers for mainstream users who simply wanted to monetize their idle computing resources."

The challenges were multi-faceted:

- **Wallet Connectivity Issues:** Network participants had to leave the GAIMIN platform to connect external wallets, creating a disjointed experience.

- **Wallet Creation Complexity:** The traditional Web3 onboarding process, requiring seed phrase management, was overwhelming for non-crypto-native users wanting to join the network.

- **Gas Fee Complications:** Users needed to purchase and manage native tokens for each blockchain just to cover transaction fees, adding unnecessary complexity to the reward process.

- **Fragmented User Experience:** Gaimin needed to maintain a seamless experience across multiple platforms (gaimin. gg, gaimin. fan, and gaimin. cloud) while preserving the decentralized nature of their network.

The core challenge was clear: how could Gaimin maintain the benefits of a decentralized infrastructure network while delivering the intuitive, frictionless experience needed for mass adoption?

## The Solution: A fully integrated, Self-custodial wallet powering gamers

After evaluating potential partners, Gaimin selected Openfort based on their "strong development capabilities" and collaborative approach to customizing solutions. The implementation process was highly collaborative, resulting in a tailored Web3 experience that aligned perfectly with Gaimin's DePIN ecosystem needs.

The Openfort implementation delivered three critical capabilities:

1. **Fully Embedded Wallet Infrastructure:** Openfort's technology enabled Gaimin to create the Gaimin Smart Wallet (GSW), a self-custodial solution that eliminates redirections to third-party applications. Network participants can receive rewards and contribute computing resources throughout the ecosystem without leaving the familiar Gaimin interface.

2. **Simplified User Authentication:** Instead of managing seed phrases, users can access their Web3 wallets through an innovative two-layer authentication system—an initial password for their Gaimin account plus a separate recovery password that replaces traditional seed phrases, dramatically simplifying the process of joining the DePIN network.

3. **Gasless Transactions in $GMRX:** Openfort enabled Gaimin to cover all transaction fees using their native $GMRX token. This eliminated the need for users to acquire different tokens across various blockchains, removing a significant barrier to participating in the decentralized computing network.

"The integration process with Openfort was exceptionally smooth," notes the Gaimin team. "Their team worked closely with us to customize the solution to our exact requirements, allowing us to create a DePIN that truly scales to mainstream adoption."

## The Results: More than 50,000 users have migrated to smart wallets in just one month

![gaimin-wallet.jpg](https://blog-cms.openfort.io/uploads/gaimin_wallet_d3f95ee14d.jpg)

While still in the early stages of user onboarding to their Smart Wallet, GAIMIN has already realized significant improvements across their entire DePIN ecosystem:

**Seamless Network Participation:** By eliminating redirections and simplifying wallet management, GAIMIN now offers what they describe as a "Web3-native yet Web2-feel" experience. Users can contribute computing resources and receive rewards without confronting unfamiliar blockchain interfaces or technical complexity.

**Accelerated Onboarding:** The streamlined wallet creation process has removed substantial barriers to entry for DePIN participation. **Over 50K people migrated to our new Gaimin SSO in the first month to gain access to our smart wallet**.

**Frictionless Rewards Distribution:** By covering all gas fees in $GMRX, Gaimin has created a seamless reward system throughout their ecosystem. This allows users to focus on contributing computing resources rather than managing multiple tokens for transaction fees.

**Platform Cohesion:** The single sign-on integration works seamlessly across all Gaimin platforms, creating a unified ecosystem where users' wallets remain connected as they move between services, ensuring continuity in their DePIN participation.

"Openfort's solution has been crucial in making decentralized infrastructure accessible to mainstream users who previously found Web3 too complicated," says the Gaimin team. "We're now able to harness idle computing power at scale by removing the traditional barriers to participation."

## Looking Forward

As user adoption of the Gaimin Smart Wallet continues to grow, the company anticipates further collaboration with Openfort to enhance functionality and scale their decentralized computing network. One upcoming feature will allow users to swap smart contract addresses via a one-click function when they forget their recovery password, further streamlining DePIN participation.

"Our partnership with Openfort has been instrumental in breaking down the traditional barriers between Web2 and Web3," concludes the Gaimin team. "We're now able to deliver true access to decentralized infrastructure with the simplicity users expect from mainstream applications—a combination that's essential for the next generation of DePIN solutions."

The Gaimin-Openfort partnership demonstrates how thoughtful implementation of Web3 infrastructure can preserve the benefits of decentralization while eliminating adoption barriers, creating a seamless pathway for mainstream users to participate in the decentralized physical infrastructure network.

How Gaimin reduces the onboarding complexity by using Openfort

*“Most players didn’t even realize they were using crypto – they just played” – Praveen Kumar, CTO, GAMP*  

## The breaking point: Web3 tools stifling growth 
As GAMP scaled its play-to-earn ecosystem, legacy Web3 infrastructure began cracking under pressure. Manual integrations with Ethereum standards added 3-4 weeks to every feature deployment—engineers joked they were “debugging smart contracts *during* live tournaments.” Private key management metastasized into a full-blown operational nightmare: 15% of staff time went to key recovery, and 72% of players abandoned onboarding at wallet creation.  

“We’d built this vibrant metaverse, but onboarding felt like filing taxes,” admits Praveen Kumar, GAMP’s CTO. “MetaMask’s 12-step flow confused even our devs. Players would DM us screenshots of seed phrases asking, *‘Is this part of the game?’*”  

Worse yet, financial planning became guesswork. Gas fees fluctuated wildly, causing 42% budget overruns. “We’d test features on Polygon zkEVM, then mainnet costs would torpedo projections,” Kumar recalls. “Building for 50K users? Might as well have used a Magic 8-Ball.”  

## The fix: Openfort’s invisible blockchain layer
GAMP overhauled its stack with Openfort’s account abstraction platform in under a week. The team:  
1. Replaced MetaMask with **social logins** using Openfort’s SDK (“90 minutes to first live transaction”)  
2. Deployed **gas optimization** algorithms that batch-processed L2 transactions  
3. Integrated **real-time analytics** revealing $18K in annual zkEVM savings  

“Openfort didn’t just give us tools—they redesigned our UX playbook,” says Kumar. “Their engineers mocked our game builds to stress-test edge cases. One found a bug where wallet pop-ups overlapped boss fight cutscenes. Game-changer.”  

The partnership prioritized "invisible Web3":  
- **Auto-generated wallets** via email/OTP  
- **Session keys** allowing item loans without seed phrases  
- **Gasless transactions** sponsored via $GAMP tokens  

“Players thought we’d nerfed the tutorial,” Kumar laughs. “Nope—Openfort just made blockchain *actually* seamless.”  

## Results: Mainstream gamers, enterprise-grade security
In 24 hours post-launch:  
- **1,492 users onboarded** (478% increase)  
- **5,124 in-game token transactions**  
- **82% fewer “gas help” tickets**  

Operationally:  
- **3X faster deployments** (11 days vs. 34)  
- **Zero key-related breaches** since migration  
- **40% lower L2 costs** via Openfort’s analytics  

“Half our Discord thought we’d switched back to Web2,” Kumar notes. “But chain explorers don’t lie—we’ve got more on-chain activity than ever.”  


### The verdict: Why Openfort won
**Q: Why ditch MetaMask/RainbowKit?**  
*“They’re tools for traders, not gamers. Openfort gave us Web2 simplicity with Uniswap-level security.”*  

**Q: Best surprise?**  
*“Players organically built a token gift economy. We see 500+ daily P2P sends—no ‘blockchain’ UI prompts.”*  

**Q: Next move?**  
*“Cross-game item portability. Openfort’s interoperable accounts let rare swords jump between our RPGs.”*

How Moonlit Games eliminated 90% of Wallet Drop-offs

Lost Dungeon is a casual blockchain game that demonstrates how to best leverage the potential of blockchain technology in gaming. [**Repo here**](https://github.com/openfort-xyz/lost-dungeon).

This article details how to build “invisible” blockchain features so that:
- For players can just focus on gameplay, and still get the full benefits of web3 (ie. in-game asset ownership). No wallet connection for authentication, no gas fees or popups for transactions. 

- For game developers, familiar gaming tools at your disposal, powerful and reliable SDKSs and APIs with the necessary tooling to start monetizing at any point.

## Why we built a Web3 Game
The goal of Lost Dungeon is to show the power of blockchain technology in the games. Traditionally players often suffer from limitations such as lack of gaming ownership and not being able to enjoy their progress in other ecosystems. 

Our aim with Lost Dungeon was to establish an experimental mini-game that empowers players with complete control over their in-game assets. It is designed to reward gameplay with gaming value and provides players with genuine ownership over claimed items. 

Moreover, it also enhances the gaming experience through unprecedented levels of interactivity and interoperability, extending beyond the game itself.

## Game Architecture
![RECOVERY1.svg](https://blog-cms.openfort.io/uploads/RECOVERY_1_ad9e2b0577.svg)

### Blockchain
Lost Dungeon is built on top of Avalanche Fuji Testnet. Leveraging Avalanche as the game’s public cloud infrastructure ensures transparency, security and immutability. Developers need to “do your own research” on the blockchain you want to launch and grow as each blockchains have different tradeoffs, demographics and focus.

### Gaming Backend
Lost Dungeon uses Playfab as a backend as a service solution together with Azure functions to execute certain custom logic. At its core, the gaming assets and economics of the game are in the blockchain making the game a “web2.5” approach. 

### Player Authentication
Lost Dungeon usesPlayfab Authentication to onboard users with and without existing wallets. Providing a unified experience regardless of how crypto-saby the player is.

## In-game Wallet
The first component of a game is the player. In blockchain, the player has both a profile/identity and a payment railway attached. In traditional blockchain we call this wallets and are crucial to hold in-game currencies and assets through the game. Wallets (or vaults in the gaming context) are crucial and can be generated at the backend of the game not to disrupt the player’s experience.

![RECOVERY2.svg](https://blog-cms.openfort.io/uploads/RECOVERY_2_f6d6e6805e.svg)

- **Onboarding crypto and non-crypto players**
In-game wallets offer standardize experiences for both crypto native and non-crypto native player base. We create smart wallets for every single player signing up for the first time. The main difference is that players with existing wallets will be the owner of the smart wallet being completely self-custodial. Players without a wallet will have a non-custodial wallet created link with their email. Both are completely indistinguishable.

Here is how we link an email to a non-custodial account

```js
import Openfort from "@openfort/openfort-node";
const openfort = new Openfort(process.env.OPENFORT_API_KEY);
const OFplayer = await openfort.players
    .create({
        name: req.body.CallerEntityProfile.Lineage.MasterPlayerAccountId,
    });

```

- **Playing as a Guest**
We’ve also created a “play as a guest” button where players enjoy the game without having to sign up. This onboarding creates a wallet in the background that players would be able to claim if they want to save their progress in the game. 


## Gasless Transactions
Gas transactions are a massive friction point for onboarding new users. Onboarding a complete newcomer to Web3 involves creating a wallet and acquiring a native token to initiate their first transaction. For game developers, this process can deter potential users as they typically need to purchase the native token through a fiat on-ramp, which often necessitates Know Your Customer (KYC) procedures.

Granular gas sponsoring is essential to the gaming experience and it’s no exception with the Lost Dungeon, enabling players to perform actions on the blockchain without needing initial funds or worrying about the costs of transaction fees.

Openfort lets you define a gas policy to handle the payment transaction fees on behalf of the players. This pairs with any created wallet who doesn’t hold any funds initially. This combo enables a smooth and uninterrupted gaming experience, without the need for players to transfer AVAX or worry about gas prices.

Read more about [gasless transactions](https://www.openfort.xyz/blog/technical-dive-gas-sponsorship).
## Signless Transaction
Signless transactions (Session Keys) are a massive leap forward for user experience. They allow users to pre-approve an application's transactions according to a set of parameters. Session keys are used to simply pre-approve your session and play the game without constantly being bombarded by your wallet asking “confirm this transaction”.

Here is how we use session keys on Lost Dungeon. We create a local session key to be able to buy a weapon (mint an asset) by pre-approving functions of the smart contract during a specific period of time.

```c#
using Openfort;

public class Web3AuthService: MonoBehaviour
private OpenfortClient _openfort;

private void Start() {
  _openfort = new OpenfortClient("pk_test_…");
}
private void RegisterSession() {
  Debug.Log("Registering session...");
  var loadedSessionKey = _openfort.LoadSessionKey();
  if (loadedSessionKey == null) {
    var sessionKey = _openfort.CreateSessionKey();
    walletConnectorKit.ChangeState(State.CreatingSessionKey);
    _openfort.SaveSessionKey();
  }
}
```

## Beyond the wallet 
### Purchasing Assets (ERC721)
The Shop screen enables players to purchase weapons using their $GOLD tokens. Let’s walk through how this works.

The ERC721 contract allows players to “claim” the assets as long as they meet the onchain conditions defined on the claim condition of the contract. When a player clicks on “Buy” we hook up the purchase buttons of each UI item with the claiming function.


If the conditions are met, the player will exchange some $GOLD tokens for a weapon NFT.

```ts
const currencyAddress = process.env.GOLD_CONTRACT_ADDRESS;
const weaponAddress = process.env.OF_WEAPON_CONTRACT;
const _proof = [
    "0x0000000000000000000000000000000000000000000000000000000000000000",
];
const _quantityLimitPerWallet = 1;
const _receiver = resultData["OFplayer"].Value;
const _tokenId = Number(offerId);
const _quantity = 1;
const _pricePerItem = {
    "0": "1000000000000000000",
    "1": "10000000000000000000",
    "2": "20000000000000000000",
    "3": "30000000000000000000",
    "4": "40000000000000000000",

};
const _data = "0x";
const _allowlistProof = [
    _proof,
    _quantityLimitPerWallet,
    _pricePerItem[offerId],
    currencyAddress,
];
const interaction_1: Interaction = {

### Collecting Coins -$GOLD (ERC20)

![Group 384-min.png](https://blog-cms.openfort.io/uploads/Group_384_min_6214ef1937.png)

The $GOLD token works as the in-game currency within Lost Dungeon. The in-game mechanics rely on the token to upgrade your progress in the game. 

When onboarding for the first time, we drop the player with 1 GOLD. Players complete runs to obtain GOLD Tokens, which in turn can be spent to purchase weapons from the shop. These are NFTs owned by the players, and are reflected inside and outside of the game.

Some of the mechanics implemented in the game:

- _Reading balance_.
We’ve set a CRON function to periodically refresh the player’s balance. Additionally, we hook up a refresher for related user actions that update their balance. 

- _Minting Flow_.
With Last Dungeon we used the aforementioned Sesion Keys to approve every action happening onchain. That’s in the case of the dungeon, the collection  of Gold, triggers a minting event automatically. 

We could also decide to put those transaction onchain once the game is over and batch them all together in one single mint to save on gas fees, but for the sake of this example we wanted to show how smooth it is with single transactions.

### Other notable features we could include
- **Transfer Ownership**
Allowing players with non-custodial wallets to transfer their ownership to a self-custodial wallet without exposing private keys.

- **Token Bound Accounts**
Turning battle passes or simple player avatars into smart wallets that could also host more game tokens and assets without. This approach ensure an easy transfer of wallets via the NFT directly instead of the signer.

- **Ecosystem ID**
Openfort's headless approach makes it ideal for building a gaming wallet on top of. Additionally, this enables the creation of companion apps and enhances the gaming ecosystem.

- **Playing as a guest functionality**
Playing as a guest is a common way for players to authenticate to games, and all BaaS providers offer that functionality. The problem is that if the player has made some progress while playing as a guest, they will lose it for the next gaming session.

Learn how to implement it in our [PlayFab guide](https://www.openfort.io/docs/products/embedded-wallet/unity/resources/backend/playfab).

## What makes Openfort stand out?
Openfort's Ecosystem SDK brings [cross-app wallets](https://www.openfort.io/crossapp-wallet) to the masses, by the fraction of a cost. This approach allows for a more customized and developer-friendly environment. Additionally, Openfort's commitment to innovating and advancing the concept of account abstraction for gaming presents new possibilities for developers, making it a unique proposition in the market.

| | **Alternative solutions and why the partner chose Openfort** | 
|---|---|
| Stardust | While Stardust offers a gaming kit, their solution has a high vendor lock and Merit Circle would be limited to new innovations. | 
| Sequence | Sequence provides a wallet service for games but it locks you into their ecosystem and would have been more complex to integrate with what Merit Circle has in mind. | 
| Web3auth | Web3auth specializes in MPC tech to authenticate users, but it’s not aligned with the gaming business model and comes in expensive at certain volumes. | 
| Magic Link | While Magic Link allows easy login through Amazon KMS, it doesn't offer deep integration with smart accounts and transaction management. | 
| ImmutableX Passport | Immutable Passport offers identity services on the IMX ecosystem, but it does on the other end lock into the UI of Immutable and need to be on the ecosystem. | 
| Why is Openfort better? | 1. Openfort provides a superior, gaming-focused platform tailored to the needs of the gaming community. 2. Openfort's wallet technology offers more personalized experiences and rewards for players. 3. Openfort's deep understanding of blockchain technology and the needs of gaming ecosystem’s makes it an integral partner for Merit Circle. 4. Openfort's innovative approach to smart accounts, player simplicity, and developer first sets them apart. | 

>**"The capacity of Openfort to become a true partner in our developer cycle and integrations is invaluable. They are not just a technology provider but an integral part of our journey towards onboarding more gamers into Web3 experiences,”** - Brandon, CTO of Merit Circle.

## Let’s get technical
Diving deeper into the technicalities, Merit Circle and Openfort are leveraging advanced technology to build an ecosystem that emphasizes player-centric design, interoperability, and rewarding experiences. The $BEAM token, accessible and usable across different games, adds to the inclusive nature of this gaming ecosystem. 

The interoperability of different games within the ecosystem is a key technical advancement, along with the ability to use their own smart contracts and integrate with existing products like Sphere. Through these innovations, this partnership promises a new era of digital gaming experiences.

### [Smart Accounts](https://www.openfort.io/docs/products/embedded-wallet/unity/smart-wallet)
_What it is:_
By incorporating smart contract wallets, or 'account abstraction' (following ERC4337), you can offer your users a more interactive and richer gaming experience.

_Why it's important for games:_
Beam utilizes smart contracts from Openfort, which provide you with the tools to offer your users greater flexibility and security with their accounts. This means, developers will be able to choose across a gull range of wallet configurations like Token Bound Accounts (ERC6551), Social Recovery Accounts, and more. 

### [Multi-Chain Account Support](https://www.openfort.io/docs/configuration/chains)
_What it is:_
Beam has integrated Openfort's multi-chain account support, allowing users to manage multiple blockchain accounts seamlessly.

_Why it's important for games:_
In a gaming ecosystem where different games may operate on different blockchains, multi-chain support is crucial. It allows the ecosystem to expand into new blockchain as they see fit, while mantaining the same support and experience. 

### [Gas Sponsorship and Policy Rules](https://www.openfort.io/docs/configuration/gas-sponsorship)
_What it is:_
Openfort's gas sponsorship feature has been adopted by Beam to subsidize transaction costs for the users.

_Why it's important for games:_
Having to have tokens to pay for transactions can be a barrier to entry for many gamers. By granularly sponsoring these fees, Beam makes it more accessible for users to engage in transactions, such as buying in-game items or transferring assets across accounts/,marketplaces. All by using the native token $Beam. 

### [Invisible Blockchain Interactions](https://www.openfort.io/solutions/gaming)
_What it is:_
This feature eliminates the need for constant pop-ups during blockchain interactions, offering a smoother gaming experience.

_Why it's important for games:_
Constant pop-ups can be disruptive and annoying, especially in fast-paced games. This feature enhances user engagement and keeps gamers focused on the gameplay rather than administrative tasks. By creating temporary keys the gaming ecosystem has the authorization to interact on behalf of the users for a limited set of variables. 

## What future features will Openfort support?
1. **Release of the Beam companion app**. Allowing players features like transferring assets, buying / listing on Beam marketplace through the app and asset swaps. The app will also include Vaults, which will be a self-custodial account for users to interact with their assets.

2. **Onramp/Offramp for games**. Allowing game devs to incorporate FIAT payments to their game, either to aquire more game tokens or in-game assets.

3. **Onchain subscriptions**. Allowing game devs to create subscriptions for their products and other paying mechanisms.
