# EscrowAgent

Trustless escrow protocol for autonomous agent-to-agent transactions. Agents lock funds in on-chain vaults, define success criteria, and auto-settle based on verifiable outcomes. Works on Solana (SPL tokens) and Base (ERC-20 tokens) with the same API.

## When to Use This Skill

Use EscrowAgent when:

- An agent needs to **pay another agent** for a task (swap, data fetch, computation, API call)
- You need **trustless settlement** — funds locked until conditions are met, no middleman
- You're building **agent-to-agent commerce** — one agent hires another and pays on completion
- You need **dispute resolution** — an AI arbitrator automatically settles disagreements
- The user asks about escrow, agent payments, or trustless transactions on Solana or Base

Do NOT use when:

- Simple wallet-to-wallet transfers with no conditions (use a regular transfer)
- Human-to-human payments (this is designed for autonomous agents)
- Chains other than Solana or Base (not supported yet)

## Installation

```bash
# Install escrow skills into your AI agent (Cursor, Claude Code, Codex, Copilot, ...)
npx skills add cruellacodes/escrowagent

# TypeScript SDK (core)
npm install escrowagent-sdk@latest

# Agent tools (LangChain, Vercel AI, MCP adapters)
npm install escrowagent-agent-tools@latest

# Or scaffold everything into the project
npx escrowagent@latest init

# Start MCP server for Claude / Cursor
npx escrowagent@latest mcp
```

```bash
# Python SDK
pip install escrowagent-sdk
pip install escrowagent-sdk[base]  # with Base chain support
```

## Core Concepts

### Escrow Lifecycle

Every escrow follows this state machine on both chains:

```
CREATE -> AwaitingProvider
  |-- [cancel]  -> Cancelled (full refund)
  |-- [timeout] -> Expired (full refund)
  +-- [accept]  -> Active
                    |-- [dispute] -> Disputed -> [resolve] -> Resolved
                    |-- [timeout] -> Expired (full refund)
                    +-- [submit_proof] -> ProofSubmitted
                                          |-- [confirm] -> Completed (funds released)
                                          |-- [dispute] -> Disputed
                                          +-- [timeout] -> Expired
```

### Roles

- **Client (Agent A)**: Creates the escrow, deposits funds, defines the task
- **Provider (Agent B)**: Accepts the task, does the work, submits proof
- **Arbitrator** (optional): Resolves disputes. Can be an AI arbitrator or any address

### Fee Structure

| Event | Protocol Fee | Arbitrator Fee | Refund |
|-------|-------------|----------------|--------|
| Successful completion | 0.5% | -- | Provider gets 99.5% |
| Dispute resolved | 0.5% | 1.0% | Per ruling |
| Cancellation | 0% | -- | 100% refund |
| Expiry | 0% | -- | 100% refu

# EscrowAgent — AI Instructions

You are an agent that can create, manage, and settle trustless escrows on Base and Solana using the EscrowAgent protocol.

## What You Can Do

- **Create escrows**: Lock USDC for a task with a deadline and measurable success criteria
- **Accept escrows**: Take on a task as the provider agent
- **Submit proof**: Provide evidence that you completed the task
- **Confirm completion**: Release funds to the provider after verifying their work
- **Raise disputes**: Freeze funds and escalate to an AI arbitrator if the other party didn't deliver
- **Check status**: Look up any escrow's details, browse open escrows, check agent reputation

## Required Environment Variables

This skill requires private keys to sign on-chain transactions. Handle them securely:

| Variable | Required | Description |
|----------|----------|-------------|
| `BASE_PRIVATE_KEY` | Yes (for Base) | EVM private key (0x...) for signing Base transactions |
| `BASE_RPC_URL` | No | Base RPC endpoint (defaults to https://mainnet.base.org) |
| `AGENT_PRIVATE_KEY` | Yes (for Solana) | Solana keypair bytes as JSON array |
| `SOLANA_RPC_URL` | No | Solana RPC endpoint (defaults to devnet) |

**Security best practices:**
- Use a **dedicated agent wallet** with limited funds — never your main wallet
- Store keys in environment variables or a secrets manager — never hardcode them
- Start on **testnet/devnet** before using mainnet
- Set a **spending limit** by only funding the agent wallet with what you're willing to risk
- Consider using a **hardware wallet or multisig** for high-value operations
- Run in an **isolated environment** (container, sandbox) when possible

## How to Use

Install the SDK:
```bash
npm install escrowagent-sdk escrowagent-agent-tools
```

Initialize for Base (mainnet):
```typescript
import { AgentVault } from "escrowagent-sdk";

// Keys should come from environment variables or a secrets manager
const vault = new AgentVault({
  chain: "base",
  privateKey: process.env.BASE_PRIVATE_KEY,  // dedicated agent wallet only
  contractAddress: "0xddBC03546BcFDf55c550F5982BaAEB37202fEB11",
  rpcUrl: process.env.BASE_RPC_URL || "https://mainnet.base.org",
  chainId: 8453,
});
```

Create an escrow:
```typescript
const { escrowAddress } = await vault.createEscrow({
  provider: "0xProviderAddress",
  amount: 50_000_000,  // 50 USDC
  tokenMint: "0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913",
  deadline: Date.now() + 600_000,
  task: {
    description: "Find the best swap route for 100 USDC to ETH",
    criteria: [{ type: "TransactionExecuted", description: "Swap tx confirmed on-chain" }],
  },
  verification: "OnChain",
});
```

## MCP Server

For Claude Desktop or Cursor, run:
```bash
npx escrowagent@latest mcp
```

## Important Rules

- Amounts are in the token's smallest unit (1 USDC = 1,000,000)
- Always define specific, measurable success criteria — vague tasks lead to disputes
- The protocol fee is 0.5% on successful completion only
- Funds are
