UTXOs
Bitcoin has no balance and no contract to call. Spending means picking unspent outputs and signing each one.
Real Bitcoin. Not a receipt for one.
A token that stands in for Bitcoin is not Bitcoin. This moves the actual asset, in and out, on the real chain.

Give them the real thing
Bitcoin is the asset people most want to move and the one most products quietly refuse to. The usual substitute is a wrapper minted against someone's reserves. Users have worked that out. RAVN routes native BTC both ways and settles the canonical asset.
Bitcoin is not another EVM chain
No contracts
You cannot deploy a router on Bitcoin. Venues move it with time-locked contracts (HTLCs), shared-key vaults, or solvers who front the other side.
Wrapping swaps the risk
A lock-and-mint bridge does not move Bitcoin. It parks it and issues a claim, and the claim is only as good as the custodian.
Minutes, not seconds
Bitcoin confirmations take minutes. Anything promising otherwise is not quoting Bitcoin.
Two extra fields, that is all
Bitcoin is chain -1 and its token address is the literal string native. Everything else is the same three calls as any other route.
const quote = await ravn.quote({
inputChainId: 1, // Ethereum
outputChainId: -1, // Bitcoin
inputToken: NATIVE_EVM,
outputToken: 'native', // real BTC
inputAmount: '1000000000000000000',
userAddress,
destinationAddress: btcAddress, // required at quote time for BTC routes
refundAddress: btcAddress, // where the input returns if it fails
});
quote.venue.name; // Chainflip | THORChain | Relay | NEAR Intents
quote.output.amount; // in satoshis
quote.alternatives; // the BTC routes that lost, and by how muchWhat you get
Four BTC venues
Relay, NEAR Intents, THORChain and Chainflip race every Bitcoin route. Whoever delivers the most wins it.
Both directions
Bitcoin in, Bitcoin out. The real asset either way.
Signable transactions
Wallets built for Ethereum or Solana keep one key and one balance. Bitcoin does not work that way. ravn_btc_prepare_send builds the Bitcoin payment so they only have to sign.
Coverage lookup
GET /tokens/btc-coverage says which tokens on a chain really route from native BTC. Gate your UI on that instead of guessing.
Honest timings
Every quote carries estimatedTimeSeconds and says when it is an estimate. Bitcoin routes report minutes.
Firm floors
Some BTC routes are firm. guaranteedMin is what lands, or the swap does not settle at all.
And back out again
Selling into Bitcoin is one send from your own wallet. The venue pays real BTC to your address.
