FAQs

User Controlled - Infrastructure model where only end-users are allowed to initiate transactions, allowing them control over their assets.


Developer Controlled - Infrastructure model that grants developers the ability to manage assets on behalf of their users, allowing them to create a more familiar, streamlined experience.


Both Developer Controlled and End-User Controlled wallets can be created as Externally Owned Accounts (EOA), or Smart Contract Accounts.

Multi-party computation (MPC) is a cryptographic solution to multi-sig. MPC wallet technology manages private keys by distributing key-shares across multiple parties, securing against accidental or intentional acts to misuse private keys.

Gas Station charges include the cost of the gas fees (network fees) you’ve sponsored in USD, plus a 5% fee charged by Circle. Learn more here.

Circle leverages the sponsor paymaster smart contract introduced in ERC 4337 to facilitate third-party payment for gas fees. Developers can configure their sponsorship policies to work with Circle’s paymaster smart contracts set up on each blockchain to deliver gasless transaction experiences.

As Circle utilizes ERC 4337, Gas Station only works with smart contract accounts that have been created with Programmable Wallets. Support for external smart contract accounts is coming soon. Alternatively, for EOA wallets gas fee sponsorship, we recommend developers to use a relayer tool that supports ERC-2771 or ERC-3009.

Programmable Wallets support Ethereum, Polygon, and Avalanche on both mainnet and testnet.

Testnet: Ethereum, Polygon

Mainnet: Ethereum, Polygon

A Monthly Active Wallet (MAW) is a Programmable Wallet from Circle that conducts any on-chain transaction within the month such as initial wallet creation and sending or receiving funds/NFTs.

A USDC Monthly Active Wallet is a MAW that holds at least 10 USDC at all times within the month period and is active per the definition above.
