Advantages & Highlights
The Gelato bundler & paymaster take a new approach to ERC-4337 and offer various advantages whilst remaining fully compatible with other implementations.
All major EVM-compatible networks are supported, including all Gelato Rollups.
1Balance paymaster sponsors operations across all networks with just a single deposit. This allows for easier accounting & management of funds as well as increased transparency.
Transaction fees are settled post-execution so users are charged exact amounts and not overcharged like is common with other bundlers (e.g.,
preVerificationGas).Cheaper transactions due to not incurring on-chain paymaster and fee transfer overhead.
Instant inclusion as there is no need to wait for other
UserOperationsto form a bundle.MeV Protection as all transactions on Ethereum Mainnet are executed through Flashbots.
Smart Accounts have unlimited freedom during validation & execution - no blacklisted opcodes or restrictive gas limits. This enables more elaborate signature verification and authentication logic.
Built on top of the existing Relay infrastructure which is battle-tested and scalable.
The key difference between Gelato and other bundlers is that no EntryPoint deposit or on-chain paymaster is required. Instead, 1Balance settles transaction fees post-execution across all supported networks.
This avoids per-chain user deposits and ensures that the exact amount of gas consumed is charged with 100% accuracy. This is possible by setting maxFeePerGas=0 so that the EntryPoint doesn't require any fee payment (requiredPrefund=0).
