Paymaster
Zyfai sponsors all gas fees for its users. Every transaction executed by a Zyfai Agent, including account deployment, rebalancing, and auto-compounding, is gasless for the end user.
This is made possible through a Paymaster: an ERC-4337 component that covers gas costs on behalf of the user's Smart Account, so users never need to hold native gas tokens (e.g. ETH) to interact with DeFi protocols through Zyfai.
Users deposit and earn yield in stablecoins without ever needing to manage gas tokens.
Zyfai uses Pimlico's Verifying Paymaster for gas sponsorship across all supported chains.
Pimlico is one of the most widely adopted ERC-4337 infrastructure platforms in the ecosystem, trusted by teams like MetaMask, Safe, and Consensys and deployed across 100+ EVM-compatible chains.
Pimlico's paymaster contracts are audited. Details can be found in the Transparency & Audits section of this documentation.
