Enabling developers to get transactions validated fast, reliably and securely
Gelato Relay enables web3 developers like you to get on with what you do best, building. Gelato handles the blockchain complexities for you, every step of the way, from the moment you initiate the transaction, to the moment it is validated on-chain. We take the utmost care to make sure your transaction is relayed from off-chain to successfully carried out on-chain in the shortest amount of time, reliably within the next few blocks, and with no downtime.
We support 17 EVM networks and a multitude of ways to pay using either native or ERC-20 tokens. In combination with Gelato 1Balance, a flexible cross-chain gas tank system which allows for payment across all 17 networks using just one balance on the chain of your choosing.
