# Supported blockchains

Openfort supports the EVM and Solana ecosystems. Two things vary from chain to chain:

* **Which products and capabilities are available.** Signing and wallet management work everywhere; account-abstraction features (smart accounts, the 4337 bundler, and gas sponsorship) depend on the chain. See the matrix below.
* **Which contracts are deployed.** The factory, account implementation, and paymaster addresses differ per chain. Look them up on the [Entity addresses](/docs/configuration/addresses) page.

## Capabilities by product

| Capability | EVM | Solana |
|---|---|---|
| Embedded (client-side) wallets | ✓ | ✓ |
| Server (backend) wallets | ✓ | ✓ |
| Smart accounts — ERC-4337 | Select chains | — |
| Delegated accounts — EIP-7702 | Select chains | — |
| Gas sponsorship | Select chains | ✓ |
| 4337 bundler | Select chains | — |

* **Every chain** supports embedded and server wallets — key management, signing, and transaction submission.
* **Smart accounts, the 4337 bundler, and gas sponsorship** are available on every supported EVM chain.
* **Gas sponsorship on Solana** uses native fee-payer sponsorship rather than an ERC-4337 paymaster — see the [Solana paymaster](/docs/products/infrastructure/paymaster/solana).
* **Delegated accounts (EIP-7702)** require a chain running the latest EntryPoint (v0.8/v0.9) — see the Delegated column in the EVM table below.

## Supported EVM chains

The following EVM chains support smart accounts, the 4337 bundler, and gas sponsorship. The Delegated column marks the chains that additionally support delegated accounts (EIP-7702) via the latest EntryPoint.

| EVM chain | Testnet | Mainnet | Delegated (EIP-7702) |
|---|---|---|---|
| **Arbitrum Nova** | | 42170 | — |
| **Arbitrum One** | 421614 | 42161 | ✓ |
| **Avalanche** | 43113 | 43114 | — |
| **Base** | 84532 | 8453 | ✓ |
| **Beam** | 13337 | 4337 | — |
| **BNB** | 97 | 56 | ✓ |
| **Degen** | | 666666666 | — |
| **Ethereum** | 11155111 | 1 | ✓ |
| **Monad** | 10143 | | — |
| **opBNB** | 5611 | | — |
| **Optimism** | 11155420 | 10 | ✓ |
| **Polygon POS** | 80002 | 137 | ✓ |
| **Soneium** | 1946 | | — |
| **Zora** | 999999999 | 7777777 | — |

## Supported Solana clusters

| Solana cluster | ID |
|---|---|
| **mainnet-beta** | 1 |
| **devnet** | 2 |
| **testnet** | 3 |

Solana wallets are EOAs, and gas sponsorship is provided through the fee payer. Smart accounts and the 4337 bundler are EVM-only.

## Account types

Which account type an embedded wallet uses — EOA, smart account, or delegated account — and what each one enables is covered in [Account types](/docs/products/embedded-wallet/account-types). Delegated accounts require a chain that supports the latest EntryPoint (see the Delegated column above).

## Deployed contract addresses

Factory, account-implementation, and paymaster addresses vary per chain. Look up every contract Openfort has deployed on a given chain — searchable by name or chain ID — on the [Entity addresses](/docs/configuration/addresses) page.
