@sighash-dev/core

Framework-agnostic Bitcoin wallet connector for the ordinals ecosystem. Targets Xverse, UniSat, and OKX — the three actively-maintained wallets — and ships a first-class bulk PSBT signing primitive.

pnpm add @sighash-dev/core nanostores

import {
  SighashClient,
  createStores,
  unisatProvider,
  xverseProvider,
  okxProvider,
  UNISAT,
} from '@sighash-dev/core';

const stores = createStores({ network: 'mainnet' });
const client = new SighashClient(stores, {
  providers: [unisatProvider(), xverseProvider(), okxProvider()],
});
client.initialize();

await client.connect(UNISAT);
const { signedPsbts } = await client.signPsbts({ psbts: [psbt1, psbt2, psbt3] });

For React, prefer @sighash-dev/react.

Key features

• Native bulk-sign where supported: UniSat (signPsbts), Xverse (signMultipleTransactions), OKX (per-PSBT options array). One wallet prompt for N PSBTs.
• Transparent sequential fallback when bulk RPCs throw — your call still resolves.
• autoFinalized: false by default for signPsbt / signPsbts — partial-sign flows (marketplace listings) work out of the box.
• InputToSign widening with publicKey + sighashTypes (e.g. SIGHASH_SINGLE|ACP at 0x83) for advanced flows.
• Auto-derive inputsToSign from a PSBT against the connected wallet's addresses, including taproot (ECC initialized at module load).
• TypeScript-first, strict types, minimal public surface.
