Out of gas.
Not out of options.

Tokens in the wallet, zero ETH for fees. It is the one deadlock every chain shares. HoodGas breaks it: sign once, gas-free, and a relayer swaps your USDG to ETH and sends it back to you on Robinhood Chain.

Refuel

Choose a token and an amount. The signature is free. It never touches the chain. The relayer pays every fee from there and you receive ETH, minus five percent.

Method

Getting ETH requires a swap. A swap requires ETH. The loop is cut with signatures instead of transactions.

02.1

Sign, don't send

Your wallet signs an ERC-2612 permit or a Permit2 message locally, off-chain. It authorises one exact amount, with a deadline, and costs nothing.

02.2

The relayer works

It submits your permit, pulls the tokens, and swaps them to ETH through Uniswap v3 on Robinhood Chain, paying every gas fee itself.

02.3

Tank refilled

ETH lands in your wallet, less a five percent fee that refills the relayer's own float. Every step is a public transaction on Blockscout.

Verifiable

No custody, no proprietary contracts. HoodGas composes public, audited infrastructure. Check every address before signing anything.

Questions

Why is signing free but swapping isn't?+

A signature is computed locally by your wallet. Nothing touches the chain, so there is no gas. The relayer wraps your signed permission inside its own transactions and pays for all of them.

Can the relayer take my tokens?+

The permit authorises one exact amount with a deadline. The relayer can pull that amount only, never your balance, never after the deadline. Every relay is public on Blockscout.

Why USDG first?+

USDG natively supports ERC-2612 gasless permits (we verified its EIP-712 domain against the on-chain contract), so the flow works even for a wallet that has never transacted. Other tokens work through Permit2 if you've approved it before, which you have if you've ever swapped on Uniswap.

Why the caps?+

0.01 ETH per relay, 0.02 ETH per wallet per rolling day. This is emergency fuel, not an exchange. Caps keep the float available for everyone.

Is this an official Robinhood product?+

No. HoodGas is an independent community tool, not affiliated with, endorsed by, or connected to Robinhood Markets. Verify everything yourself on Blockscout.
