Chains
RAVN spans EVM chains, Solana, and native Bitcoin. One integration covers all of them. Use the chain ID in every request.EVM
| Chain | ID | Chain | ID |
|---|---|---|---|
| Ethereum | 1 | Base | 8453 |
| Optimism | 10 | Arbitrum | 42161 |
| BNB Chain | 56 | Linea | 59144 |
| Unichain | 130 | Avalanche | 43114 |
| Polygon | 137 | Robinhood | 4663 |
| zkSync Era | 324 | HyperEVM | 999 |
| World Chain | 480 |
Non-EVM
| Chain | ID | Notes |
|---|---|---|
| Solana | -2 | SPL and native SOL. Use the mint So1111...1112 for native SOL. |
| Bitcoin | -1 | Native BTC, with no wrapping and no cbBTC intermediary required. |
Native coin on any EVM chain uses the sentinel address
0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. Amounts are always strings in the token’s smallest
unit (wei, lamports, satoshis).NO_LIQUIDITY if none can.
Venues
RAVN aggregates nine venues across three settlement models. On every quote, the eligible venues are queried in parallel and the best real output wins. Each venue maps to one execution type.| Venue | Type | Execution | Serves |
|---|---|---|---|
| 0x Gasless | RFQ market maker | SIGNATURE | EVM same-chain |
| Bebop | RFQ market maker | SIGNATURE | EVM same-chain |
| CoW Protocol | Batch auction and RFQ | SIGNATURE | EVM same-chain |
| Jupiter Ultra | On-chain aggregation | TRANSACTION | Solana |
| Across | Intent and solver network | TRANSACTION | EVM cross-chain, cross-ecosystem |
| Relay | Relayer network | TRANSACTION | EVM and Solana, same and cross-chain |
| Mayan | Intent and auction (Swift) | TRANSACTION | Cross-chain, cross-ecosystem |
| NEAR Intents | Intent network (1Click) | DEPOSIT | Any to any |
| Rift | Native BTC orchestration | DEPOSIT | Native Bitcoin |
All venues settle in the canonical asset. None of them wrap, mint synthetics, or bridge.
RFQ and gasless venues let the user swap with zero native gas, because they sign an off-chain
message and a solver covers the gas.
Settlement models
RFQ market makers
Professional market makers quote a firm, signed price. The user signs and a solver settles.
Zero slippage, zero gas.
Intent networks
The user expresses an intent, or deposits the origin asset, and solvers compete to fill and
deliver on the destination.
Solver and relayer networks
Relayers fill on the destination chain and deliver the canonical asset. This gives fast
cross-chain execution without bridging.
/health endpoint always reports the
current live venue set.
