Packages

All packages live in Pactwright-Kit. None is on npm yet; until the first release, depend on them from a clone.

Package	For	Purpose
@pactwright/core	Everyone	Schemas, hashing, Merkle proofs, exact amounts, network configuration
@pactwright/contracts-client	Agents, sellers	Typed client for the pact contract, generated from its bindings
@pactwright/agent	Agent builders	The buyer: find, buy, await, certificate; sponsored accounts; metered sessions
@pactwright/seller	Sellers	pact() middleware for Express and pactHono for Hono; delivery receipts; refund and settle hooks
@pactwright/mcp	LLM agents	MCP tools: find sellers, buy, get a pact, dispute, get a certificate
@pactwright/adapters	Integrators	Pluggable discovery, reputation, spending gate, wallet and verifier
@pactwright/cli	Operators	pactwright verify, pact, agent-create, agent-topup
services/verifier	Verifier operators	The verifier service

Amounts

Amounts are decimal strings in TypeScript and i128 stroops on-chain. They’re converted in exactly one place, @pactwright/core’s amounts.ts, so a rounding bug can’t hide anywhere else.

import { toStroops, fromStroops, buildTree, verifyProof } from "@pactwright/core";

toStroops("1.25");        // 12500000n  (USDC has 7 decimals)
fromStroops(7500000n);    // "0.75"

const tree = buildTree([leafA, leafB, leafC]);
verifyProof(leafA, tree.proofs.get(leafA)!, tree.root); // true, same as ReceiptAnchor.verify_receipt
