Note
The Fireblocks Gasless Service is a premium feature that requires additional purchase. Contact your Customer Success Manager if you're interested in this feature.
Overview
The Fireblocks Gasless Service lets you delegate fee payments for supported ERC-20 tokens on EVM-based blockchains to a dedicated vault account or a third party. This allows all dependent vault accounts to transfer tokens without first depositing the relevant base asset, such as ETH.
Gasless Service is separate from the Fireblocks Gas Station and supports different protocols.
Gasless Service terminology
Gasless Service is based on the following main definitions:
- Local gasless relay: A dedicated vault account configured as the gasless relay for transactions from other vault accounts in the same workspace.
- Third-party gasless relay: A separate workspace configured as the gasless relay for transactions from your workspace.
- Fireblocks workspace as a relay: A Fireblocks workspace configured as the gasless relay provider for transactions from other workspaces.
- Relay mechanism: The protocol used to implement fee delegation. Gasless service currently supports ERC-3009 and ERC-2771, with projected support for EIP-7702/3074.
- Applicable assets: Assets that can use the gasless service, based on the token contract, the blockchain standards, the relay, and all supported mechanisms. This is currently limited to USDC and DAI on Ethereum, and any contract that uses ERC-3009/ERC-2771. Learn more about configuring gasless settings for individual transactions.
