Biconomy is one of the established account abstraction providers. It offers smart accounts, a bundler and a paymaster service that can sponsor gas or let users pay in ERC-20 tokens, all accessible through an SDK. For many apps, it is a fast way to offer gasless transactions and smart wallets without building and running that infrastructure yourself.
What We Integrate
- Smart accounts: creating accounts for your users, including passkey or social login, and connecting them to your app.
- Gas sponsorship: paymaster policies that define which users, contracts and actions you pay for, see gas sponsorship.
- ERC-20 gas payment: letting users pay network fees in tokens such as USDC, see token paymasters.
- Session keys: limited, temporary permissions so users do not have to sign every action, useful for games and trading, see session keys.
- Batching: several actions, such as approve and swap, in one user operation and one signature.
Doing It Well
- Policies with limits: sponsorship rules per user and per day, so bots cannot drain your gas budget.
- Balance monitoring: alerts before the paymaster balance runs out, so your app does not suddenly stop working.
- Fallbacks: a plan for when the provider is unavailable, such as letting users pay gas themselves.
- Avoiding lock-in where it matters: keeping your own code independent of one provider's SDK where possible, so switching later is feasible.
Frequently Asked Questions about Biconomy Integration
Biconomy or our own paymaster?
Biconomy is a good fit to get started quickly with standard sponsorship rules. Your own paymaster makes sense when your rules are specific to your product or when service fees add up at your volume, see custom paymaster development.
Which chains does Biconomy support?
Ethereum and most major EVM layer 2 networks. We check current support for the chains you need before integrating, as provider coverage changes over time.
Can we switch providers later?
Yes, if the integration is designed for it. Smart accounts and paymasters follow ERC-4337, so the main work in a switch is in the SDK layer, which we keep thin.
Who owns the code?
Ownership of the source code is set out in the contract, and the code can be fully yours, including documentation and tests.
