Tachi SDK

TypeScript SDK for the Tachi BTC daemon RPC.

Installation​

npm install @tachibtc/tachi-sdk-ts

Quick Start​

import { TachiClient } from "@tachibtc/tachi-sdk-ts";

const client = new TachiClient({
  baseUrl: "https://rpc-regtest.tachibtc.com", // or "https://rpc-signet.tachibtc.com"
});

// Health check
const health = await client.getHealth();
console.log(health.status, health.validators);

// Get all validators
const { validators } = await client.getValidators();

// Broadcast a transaction (hex-encoded, no 0x prefix)
const result = await client.broadcastTxSync("deadbeef...");

// Bitcoin RPC proxy
const info = await client.bitcoinRPC({ method: "getblockchaininfo" });
console.log(info.result);
info

Transaction hex strings do not use a 0x prefix. Use "deadbeef", not "0xdeadbeef".

What's in this SDK?​

The SDK provides a typed client for 46 of the daemon's 47 RPC routes (all except POST /tachi_validators/register, a bootstrap-node-internal endpoint deliberately excluded to avoid inviting registration-flood abuse):

  • Health & Status — node health, sync status
  • Validators — list, count, live, register
  • Network — peer info, net info
  • Transactions — broadcast (async/sync)
  • Queries — ABCI queries
  • Bitcoin RPC — proxy to underlying bitcoind
