What Relay does
Relay is a cross-chain filler. You sign one deposit on your chain; a relayer pays you ETH on Robinhood Chain (chain 4663) from its own inventory, then settles with your deposit. Your funds never sit with anypool.
Timings and fees
| Relay quote into ETH on 4663 | about a second |
| Fill on Robinhood Chain | usually seconds after your deposit confirms |
| Robinhood Chain block time | about 0.1 s |
| Gas on Robinhood Chain | about 0.02 to 0.03 gwei |
| Relay fee | taken from the landed amount, shown in the quote |
We keep about 0.0003 ETH back on Robinhood Chain to pay for the zap transaction.
If a bridge leg fails
Refunds go back to the origin chain
If Relay cannot fill, your deposit is refunded on the chain you paid from. The app shows the state of every request until it is filled or refunded.
