TypeScript SDK for Harbor bonded refunds on Solana: PDA helpers, instruction builders, receipt codec, ed25519 verify, account decoders.

npm i @infantmen-labs/harbor-sdk

import {
  bondPda,
  decodeBond,
  receiptMessageBytes,
  verifyEd25519,
} from "@infantmen-labs/harbor-sdk";

// Locate any merchant's bond — derived offline, no RPC call.
const [bond] = bondPda(merchant, mint);

// Read its health: bonded, reserved, and free collateral.
const info = await connection.getAccountInfo(bond);
const { amount, reserved, openDisputes } = decodeBond(info.data);

// Verify every delivery before paying for the next unit.
const ok = verifyEd25519(signer, receiptMessageBytes(receipt), signature);

What it covers: bondPda / bindingPda / disputePda / receiptPda / treasuryPda / claimPda, instruction builders for all 11 program entrypoints, the frozen 185-byte receipt layout, voucher bytes, and zero-dependency account decoders.
