Openfort vs Biconomy
Biconomy is migrating accounts to new MEE contracts. Move to a maintained, full ERC-4337 stack.
No credit card required • Free testnet accounts
Why developers migrate to Openfort from the Biconomy SDK

More than account abstraction primitives
Biconomy gives you paymasters, a bundler, and a smart-account SDK. You still need an embedded wallet, an auth layer, a signer, and orchestration glue. Openfort delivers the complete wallet stack under one SDK: auth, embedded wallets, smart accounts, paymasters, session keys, and a policy engine.
OpenSigner: open-source, self-hostable key management
Openfort’s key management, OpenSigner (opensigner.dev), is open-source and self-hostable. You can audit the code, fork it, or run it inside your own infrastructure. The signer is the most sensitive part of the stack — your team should be able to inspect it.
Agent wallets out of the box
Openfort agent wallets ship with session keys, policy-based spending caps, x402 for HTTP-native payments, and TEE backend signing. Build autonomous payment agents in days, not weeks.

Scale your app, not your costs.
Biconomy publishes no rate card — pricing is quote-only, and sponsored gas is marked up on top of it. Every Openfort rate is on the pricing page before you talk to anyone.

“Openfort has been an instrumental piece of technology for our platform. They helped us from integration to auditing the implementation.”

Frequently Asked Questions
Can't find your answer?
Biconomy has shifted to its Modular Execution Environment (MEE) architecture and provides a migration path for older smart accounts to new contracts. If you are re-integrating anyway, it is a natural moment to move to Openfort's maintained ERC-4337 stack (smart accounts, paymasters, and session keys) with open-source, self-hostable key management via OpenSigner.
Biconomy is account-abstraction infrastructure: paymasters, bundlers, and a smart-account SDK. Openfort is a complete wallet stack that includes all of that plus embedded wallets, auth orchestration, session keys, and open-source key management via OpenSigner. With Biconomy you still need to source and integrate auth, signing, and an embedded wallet UX separately. Openfort delivers it under one SDK.
Yes. Both are native. Openfort is bundler-agnostic and ships built-in paymasters for gasless transactions, session keys, batched operations, and a policy engine. You can use Openfort smart accounts on every major EVM chain without stitching together a separate bundler + paymaster.
Openfort wallet creation is sub-100ms and signing is in the 100–150ms range. Public, reproducible benchmarks at openfort.io/benchmarks. Latency matters for consumer wallet UX and agent flows where every extra second compounds.
Yes. Openfort is bundler-agnostic so you can route through whichever bundler you prefer, including running your own. Most teams start with Openfort’s built-in paymaster and bundler for simplicity.
Openfort uses transparent, usage-based pricing per operation (wallet creation or transaction). That keeps costs predictable as you scale, without per-seat or per-MAU surprises.
OpenSigner, the key management system that powers Openfort, is fully open-source and self-hostable at opensigner.dev. You can audit it, fork it, or run it inside your own infrastructure.
Openfort agent wallets ship with session keys, policy-based spending limits, x402 for HTTP-native payments, and TEE backend signing for server-side agents. Biconomy provides AA primitives you can build agents on top of, but you assemble the full agent wallet yourself.
