Payment rails
Currencies, decimals, asset ids, addresses and limits for every payment rail.
A payment rail is one currency on one network. Every quote, reservation, charge, refund, earning and withdrawal happens on exactly one rail.
| Rail | Asset id | Decimals | Smallest unit | Accounts |
|---|---|---|---|---|
| SOL | solana:mainnet-beta/native | 9 | lamport | Solana |
| USDC on Solana | solana:mainnet-beta/spl:EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v | 6 | 0.000001 USDC | Solana |
| ETH on Robinhood Chain | eip155:4663/native | 18 | wei | EVM |
Amounts in the API and in exports are exact integers in the smallest unit ("atomic" amounts). The website shows them in whole units.
