Tools of RAVN
	Description		Read-only	Idempotent	Open world
`ravn_btc_coverage`For a swap where native BTC is the source: how many BTC venues list each of ravn_tokens's tokens on `chainId`. A ranking hint (a token more venues list is more likely to keep routing through one venue's outage), not a gate: ravn_quote decides, and tokens off RAVN's list route from BTC too. BTC-as-source only.

`ravn_btc_prepare_send`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).

`ravn_chains`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.

`ravn_execute`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.

`ravn_quote`Get a swap quote from RAVN — same-chain or cross-chain, across 19 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.

`ravn_status`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.

`ravn_submit_signature`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_tokens`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.
