BTC on Bitcoin

The details.

NetworkBitcoin
TypeThe native coin of Bitcoin
Decimals8 (amounts in the API are whole numbers of the smallest unit)
DepositsA deposit counts once it is 2 blocks deep and its block is still part of the chain. If a reorganization removes it, it's never credited.
Minimum withdrawal0.0005 BTC
Network feesFees come from the coins being sent. A payment still unconfirmed after 30 minutes is resent with a higher fee (replace-by-fee), from the same coins to the same recipient.
AddressesNative SegWit (P2WPKH) addresses, starting with bc1q.
Asset id in the APIBTC

For developers

Deposit addresses and payouts in a few lines.

import { Valtu, depositAddress } from "@valtu/wallet-kit";
const valtu = Valtu.fromEnv();

// A deposit address for one of your customers (idempotent).
const wallet = await valtu.wallets.forCustomer("cus_42");
const address = depositAddress(wallet, "bitcoin");

// A payout of 0.0025 BTC: retries never send twice.
const amount = await valtu.assets.toBaseUnits("BTC", "0.0025");
await valtu.transfers.create({ walletId: payoutWalletId, asset: "BTC", amount, to, externalId: "payout_981" });

Python: pip install valtu, same calls (valtu.wallets.for_customer, valtu.transfers.create). Full guide: integration.
