The Gelato Paymaster & Bundler provides infrastructure for Account Abstraction, supporting both ERC-4337 and EIP-7702 standards. Sponsor gas fees, enable ERC-20 payments, and integrate with any smart account provider.

​
What is ERC-4337?

ERC-4337 implements account abstraction without requiring protocol changes. Instead of users sending transactions directly, they sign UserOperations that are collected by Bundlers and submitted to the network through an EntryPoint contract.
EIP-7702 is complementary to ERC-4337. It upgrades EOAs to smart accounts that can then use ERC-4337 infrastructure for gas sponsorship and batching.
