# Robyn AnyGas

> Gasless, cross-chain relay infrastructure for AI agents and onchain apps. A relayer
> fronts network gas and is repaid from the token being moved, so a single signed intent
> transacts across 22 EVM chains, Stellar, and Solana with no native gas balance held anywhere.

Robyn AnyGas lets an agent pay for anything on any supported chain without holding that
chain's gas token. The user (or agent) signs an EIP-712 intent — or a Permit2 / EIP-2612
permit — and the Robyn relayer pays the network fee, executes, and takes repayment
atomically from the token in flight. For cross-chain moves, Robyn runs best-of-N routing:
it quotes LI.FI, Bungee, and deBridge in parallel, executes the highest net output, and
fails over automatically. Stellar settles via Allbridge Core. Version 3.1 is live.
