Bitcoin Integration

Coming next

Bitcoin is not live yet. It will land in Smart Engines and HSuite Wallet together. There is no date. This page describes what Bitcoin support will offer.

Overview

Bitcoin is a UTXO-based chain: there are no account balances, only unspent outputs. It has no native token standard, so in Smart Engines Bitcoin will be transfer-only: you will be able to move BTC, but not mint, burn, pause, freeze or claw back. Each entity’s BTC will sit in a native P2WSH multisig address of the validators.

Payer-signed transactions

Transfers are prepared as PSBTs for the payer to sign and broadcast

Fee estimation

Fee rates in sat/vByte, by priority tier

Token & NFT Model

Bitcoin has no native token or NFT standard, and Smart Engines will not add one. Ordinals, inscriptions, BRC-20 and Runes are not part of the planned integration.

Multisig

Bitcoin entities will use Bitcoin’s native multisig rather than a single aggregated key:

The entity’s address is a P2WSH OP_CHECKMULTISIG script over the validators’ keys. It follows from those keys and the threshold, so nothing is submitted to create it: the payer’s funding transaction is the entity’s first transaction.
Each validator signs a spend with its own key, and the script needs m of the n signatures.
The entity’s rule reference is anchored on chain in an OP_RETURN output.

Genesis Services

Bitcoin takes no part in genesis. Genesis runs on Hedera (HCS topics) and XRPL (the HSUITE token and the membership NFTs) only.
