+# ClawPay — Escrow Payments for AI Agents
+
+You can send and receive trustless escrow payments on Solana using ClawPay. This skill handles the full payment lifecycle: locking funds, confirming delivery, releasing payments, and checking receipts.
+
+## Setup
+
+First, check if clawpay is installed:
+```bash
+pip3 show clawpay
+```
+
+If not installed:
+```bash
+pip3 install clawpay
+```
+
+The user's Solana wallet keypair is required. Check for it at the path in the `SOLANA_KEYPAIR_PATH` environment variable, or look for common locations:
+- `~/wallet.json`
+- `~/.config/solana/id.json`
+- `~/projects/clawpay/program-keypair.json`
+
+If no keypair is found, ask the user to provide one or generate one with `solana-keygen new --outfile ~/wallet.json`.
+
+## How ClawPay Works
+
+ClawPay is a time-locked escrow protocol on Solana. Every payment follows this flow:
+
+1. **T0 — Lock**: Buyer locks SOL into an escrow account
+2. **T1 — Deliver**: Seller must deliver before the deadline, or funds auto-refund to buyer
+3. **T2 — Verify**: Buyer confirms delivery, or funds auto-release to seller after the window
+4. **Settle**: 98% goes to seller, 1% to ClawPay, 1% to referrer (if any)
+5. **Receipt**: Cryptographic receipt minted on-chain for both parties
+
+No trust required between agents. The timeline enforces everything.
+
+## Core Operations
+
+### Pay Another Agent (Create Escrow)
+
+When asked to pay an agent or buy a service:
+```python
+from clawpay import Client
+from solders.keypair import Keypair
+from solders.pubkey import Pubkey
+
+keypair = Keypair.from_json(open("KEYPAIR_PATH").read())
+client = Client(keypair)
+
+escrow = client.create_escrow(
+    seller=Pubkey.from_string("SELLER_PUBKEY"),
+    amount_sol=AMOUNT,
+    delivery_secs=DELIVERY_TIME,       # seconds until delivery deadline
+    verification_secs=VERIFICATION_TIME # seconds for dispute window (min 10)
+)
+print(f"Escrow created: {escrow.address}")
+print(f"Amount: {escrow.amount_sol} SOL")
+print(f"Delivery deadline: {escrow.t1}")
+print(f"Verification ends: {escrow.t2}")
+```
+
+Default values if not specified:
+- `delivery_secs`: 600 (10 minutes)
+- `verification_secs`: 30 (30 seconds)
+- `amount_sol`: Ask the user — never assume an amount
+
+### Confirm Delivery (As Seller)
+
+When you've completed a service and need to confirm delivery:
+```python
+from clawpay import Client
+from solders.keypair import Keypair
+from solders.pubkey import Pubkey
+
+keypair = Keypair.from_json(open("KEYPAIR_PATH").read())
+client = Client(keypair)
+
+escrow_address = Pubkey.from_string("ESCROW_ADDRESS")
+client.confirm_delivery(escrow_address, keypair)
+print("Delivery confirmed. Waiting for verification window.")
+```
+
+### Release Funds (After Verification)
+
+After the verification window passes, anyone can trigger release:
+```python
+client.auto_release(Pubkey.from_string("ESCROW_ADDRESS"))
+print("Funds released to seller.")
+```
+
+### Refund (Missed Delivery Deadline)
+
+If the seller missed the delivery deadline:
+```python
+client.auto_refund(Pubkey.from_string("ESCROW_ADDRESS"))
+print("Funds refunded to buyer.")
+```
+
+### Check Escrow Status
+```python
+escrow = client.get_escrow(Pubkey.from_string("ESCROW_ADDRESS"))
+print(f"Status: {escrow.status}")
+print(f"Amount: {escrow.amount_sol} SOL")
+print(f"Delivered: {escrow.delivered}")
+print(f"Released: {escrow.released}")
+```
+
+### Check Agent Reputation (Receipts)
+```python
+receipts = client.get_receipts(Pubkey.from_string("AGENT_PUBKEY"))
+print(f"Total transactions: {len(receipts)}")
+for r in receipts:
+    outcome = ["released", "refunded", "disputed"][r.outcome]
+    print(f"  #{r.receipt_index}: {r.amount_sol} SOL — {outcome}")
+```
+
+## Important Constraints
+
+- **Minimum escrow**: 0.05 SOL
+- **Maximum escrow**: 10.0 SOL
+- **Minimum verification window**: 10 seconds
+- **Maximum delivery time**: 30 days
+- **Fee**: 2% on settlement (1% ClawPay + 1% referrer)
+- **Network**: Solana Mainnet (default) or Devnet
+
+## Guardrails
+
+- NEVER create an escrow without confirming the amount with the user first
+- NEVER send funds without verifying the seller's public key
+- Always display the escrow address after creation — the user needs it
+- Always check escrow status before attempting release or refund
+- If a keypair file is not found, ask the user — do not guess
+- Report all errors clearly, especially insufficient balance errors
+- When checking reputation, mention both successful and failed transactions for honesty
+
+## Verification
+
+After any transaction, you can verify on Solana Explorer:
+- Program: https://explorer.solana.com/address/F2nwkN9i2kUDgjfLwHwz2zPBXDxLDFjzmmV4TXT6BWeD
+- Transaction: https://explorer.solana.com/tx/TRANSACTION_SIGNATURE
