RAVN

Turns a DEPOSIT-type ravn_execute result (deposit.address + deposit.amount) into a ready-to-sign PSBT, so you don't have to write your own UTXO selection and fee-estimation code. If that result also has a `fee` (an integrator fee RAVN collects beside the deposit), pass its fee.address as feeAddress and fee.amount as feeAmountSats: the PSBT then pays it as a second output of the same transaction, which is the only place RAVN looks for it. Fetches your UTXOs and the current network fee rate from mempool.space (public, no auth). RAVN never sees or touches a private key — sign the returned PSBT with your own wallet and broadcast it yourself. Only one signer is ever needed (unlike PSBT flows that require coordinating signatures across multiple UTXO-holding wallets), because every RAVN BTC-source venue resolves to a plain payment to the deposit address (plus RAVN's fee output, when there is one).

For a swap where native BTC is the source, not every token on the destination chain is reachable. Returns which of ravn_tokens's list on `chainId` a BTC venue can actually route to, and how many venues serve each, so you can build a token list that matches what will really quote instead of discovering it one NO_LIQUIDITY at a time. BTC-as-source only — selling a token INTO BTC isn't restricted the same way (nearly any token can be sold into BTC), so this has nothing useful to say about that direction.

Every chain RAVN lists a token registry for (see ravn_tokens). Static, doesn't change per request, safe to cache instead of hardcoding a chain table.

Turn a quoteToken from ravn_quote into an execution payload. Returns one of three shapes (executionType): TRANSACTION (sign and broadcast yourself), SIGNATURE (sign, RAVN submits), or DEPOSIT (send the input asset to a given address). RAVN never takes custody of funds — you always sign or send from your own wallet. TRANSACTION and SIGNATURE may also include an `approval` — an ERC-20 approve() you must broadcast and wait to be MINED before the transaction/signature, or it fails (reverts on TRANSACTION; on SIGNATURE the order is accepted and silently never fills). Only present when the sold token needs it — omitted for native-coin sells and already-approved tokens. An `approval.reset` (Ethereum USDT holding a partial allowance) goes first, mined, then the approval. A result with `sandbox: true` is a test: send nothing from it.

Liveness check across every venue RAVN routes through — call before a swap if you want to know whether a route is degraded ahead of time.

For a SIGNATURE-type ravn_execute result only: submit the signature(s) you collected (over typedData, and approvalData if present) to actually place the order. RAVN decodes the venue from quoteToken and routes to the right venue-specific submit path — you never touch a per-venue endpoint. Returns a statusRef — pass it to ravn_status as `ref` to poll this swap.

RAVN's own listed token registry for one chain — populate a token picker without hardcoding one. This is "what RAVN knows about and might route", not a per-pair routability guarantee for any specific pair; call ravn_quote to check that.

Get a swap quote from RAVN — same-chain or cross-chain, across 17 chains including native (non-wrapped) Bitcoin and Solana as source or destination. Free, no API key or payment required. Returns a quoteToken; pass it to ravn_execute to get a signable/broadcastable execution payload.

Poll the status of a swap by its quoteToken and ref from ravn_execute (statusRef, deposit address, or origin tx hash). Use the quoteToken execute returned — compose rebinds hop 1 onto hop 2's deposit. Status is authoritative where the venue exposes it; a swap the venue can't track reports 'unknown' rather than a guess.

Resolve an arbitrary token address to its metadata (symbol, name, decimals) via an on-chain read — for a paste-any-address flow, when the token isn't necessarily on ravn_tokens's list.
