BSV-PAY: Agent-to-Agent BSV Payments

This skill lets you send and receive BSV (Bitcoin SV) payments to/from other Clawdbot agents. You can pay another agent to perform a task, or receive payment for performing tasks.

Quick Reference

Command	What it does
node scripts/bsv-agent-cli.mjs setup	Create wallet (first run)
node scripts/bsv-agent-cli.mjs identity	Show your public identity key
node scripts/bsv-agent-cli.mjs address	Show P2PKH receive address (for funding)
node scripts/bsv-agent-cli.mjs balance	Check wallet balance
node scripts/bsv-agent-cli.mjs pay <pubkey> <sats> [desc]	Send payment
node scripts/bsv-agent-cli.mjs verify <beef_base64>	Verify incoming payment
node scripts/bsv-agent-cli.mjs accept <beef> <prefix> <suffix> <senderKey> [desc]	Accept payment

All commands output JSON: {"success": true, "data": {...}} or {"success": false, "error": "..."}.

Set BSV_WALLET_DIR (default: ~/.clawdbot/bsv-wallet) and BSV_NETWORK (default: testnet).

The CLI script is at: skills/bsv-pay/scripts/bsv-agent-cli.mjs

To resolve imports, run with NODE_PATH pointing to the repo root's node_modules:

NODE_PATH=/home/dylan/a2a-bsv/node_modules node skills/bsv-pay/scripts/bsv-agent-cli.mjs <command>

---

First-Run Setup

If the wallet hasn't been set up yet, run:

bash skills/bsv-pay/scripts/setup.sh

This installs dependencies, builds the core library, creates the wallet, and shows your identity key. You only need to do this once.

To verify setup worked:

NODE_PATH=/home/dylan/a2a-bsv/node_modules node skills/bsv-pay/scripts/bsv-agent-cli.mjs identity

Payment Protocol (bsv-pay-v1)

Agents exchange JSON messages with "protocol": "bsv-pay-v1" and an action field. Messages are sent via sessions_send (same gateway) or channel messages (cross-gateway).

Message Types

1. PAYMENT_OFFER — Payer requests a service, states budget
2. PAYMENT_TERMS — Receiver states their price
3. PAYMENT_SENT — Payer sends BSV payment + task details
4. TASK_COMPLETE — Receiver delivers result + payment receipt
5. PAYMENT_DECLINED — Receiver declines the offer
6. PAYMENT_ERROR — Either side reports an error

For full field definitions, read: references/protocol.md

As PAYER: Sending Payment to Another Agent

Use this flow when you (or your user) want to pay another agent to do something.

Step 1: Get your identity key

NODE_PATH=/home/dylan/a2a-bsv/node_modules node skills/bsv-pay/scripts/bsv-agent-cli.mjs identity

Parse the JSON response to get data.identityKey.

Step 2: Send PAYMENT_OFFER to the other agent

Send this message to the other agent (via sessions_send or channel message):

{
  "protocol": "bsv-pay-v1",
  "action": "PAYMENT_OFFER",
  "task": "Description of what you want done",
  "maxBudgetSats": 1000,
  "payerIdentityKey": "<your identity key from step 1>"
}

Step 3: Receive PAYMENT_TERMS

The other agent replies with their price:

{
  "protocol": "bsv-pay-v1",
  "action": "PAYMENT_TERMS",
  "amountSats": 500,
  "recipientIdentityKey": "02...",
  "description": "Service description"
}

Step 4: Check budget and get approval

• If amountSats ≤ maxBudgetSats, proceed.
• If amountSats > 1000, ask the user for approval before paying.
• If the user declines, inform the other agent.

Step 5: Create the payment

NODE_PATH=/home/dylan/a2a-bsv/node_modules node skills/bsv-pay/scripts/bsv-agent-cli.mjs pay <recipientIdentityKey> <amountSats> "payment description"

Parse the JSON response. The data object is the PaymentResult containing beef, txid, satoshis, derivationPrefix, derivationSuffix, senderIdentityKey.

Step 6: Send PAYMENT_SENT with task

Send this to the other agent:

{
  "protocol": "bsv-pay-v1",
  "action": "PAYMENT_SENT",
  "task": "Full task description with all needed details",
  "payment": {
    "beef": "<from PaymentResult>",
    "txid": "<from PaymentResult>",
    "satoshis": 500,
    "derivationPrefix": "<from PaymentResult>",
    "derivationSuffix": "<from PaymentResult>",
    "senderIdentityKey": "<from PaymentResult>"
  }
}

Include the complete payment object exactly as returned by the CLI.

Step 7: Receive TASK_COMPLETE

The other agent replies with:

{
  "protocol": "bsv-pay-v1",
  "action": "TASK_COMPLETE",
  "result": "The task output...",
  "receipt": { "accepted": true, "txid": "..." }
}

Present the result to the user. Confirm the payment was accepted via receipt.accepted. Include a link to the transaction on WhatsonChain:

• Testnet: https://test.whatsonchain.com/tx/<txid>
• Mainnet: https://whatsonchain.com/tx/<txid>

As RECEIVER: Accepting Payment from Another Agent

Use this flow when you receive a bsv-pay-v1 protocol message from another agent.

When you receive PAYMENT_OFFER

1. Evaluate whether you can perform the requested task.
2. Determine your price in satoshis.
3. Get your identity key:

NODE_PATH=/home/dylan/a2a-bsv/node_modules node skills/bsv-pay/scripts/bsv-agent-cli.mjs identity

4. Reply with PAYMENT_TERMS:

{
  "protocol": "bsv-pay-v1",
  "action": "PAYMENT_TERMS",
  "amountSats": 500,
  "recipientIdentityKey": "<your identity key>",
  "description": "Brief description of what you'll do"
}

If you can't or don't want to do the task, reply with:

{
  "protocol": "bsv-pay-v1",
  "action": "PAYMENT_DECLINED",
  "reason": "Explanation of why"
}

When you receive PAYMENT_SENT

This is the critical flow. The other agent has sent you BSV. You must verify, accept, do the task, and confirm.

Step A: Verify the payment

NODE_PATH=/home/dylan/a2a-bsv/node_modules node skills/bsv-pay/scripts/bsv-agent-cli.mjs verify "<payment.beef>"

Check that data.valid is true. If not, reply with PAYMENT_ERROR:

{
  "protocol": "bsv-pay-v1",
  "action": "PAYMENT_ERROR",
  "error": "Payment verification failed: <errors>",
  "stage": "verify"
}

Step B: Accept the payment

NODE_PATH=/home/dylan/a2a-bsv/node_modules node skills/bsv-pay/scripts/bsv-agent-cli.mjs accept "<payment.beef>" "<payment.derivationPrefix>" "<payment.derivationSuffix>" "<payment.senderIdentityKey>" "payment description"

Check that data.accepted is true. If acceptance fails, reply with PAYMENT_ERROR with stage: "accept".

Step C: Execute the task

Do whatever the task field describes. This is your normal agent capability — analyze code, summarize text, generate content, etc.

Step D: Reply with TASK_COMPLETE

{
  "protocol": "bsv-pay-v1",
  "action": "TASK_COMPLETE",
  "result": "Here is the completed work: ...",
  "receipt": {
    "accepted": true,
    "txid": "<from the payment.txid>"
  }
}

---

Detecting Protocol Messages

When you receive any message, check if it's a bsv-pay-v1 protocol message:

1. Try to parse the message as JSON
2. Look for "protocol": "bsv-pay-v1"
3. Check the action field and follow the appropriate receiver flow above

If the message is mixed with natural language, look for a JSON block containing the protocol fields.

---

Pricing Guidelines

When you're the receiver and need to set a price:

Task Type	Suggested Range
Simple text response	10–50 sats
Code review / analysis	100–1000 sats
Content generation	50–500 sats
Complex multi-step task	500–5000 sats

These are suggestions. Adjust based on task complexity.

---

Spending Approval

When you're the payer:

Amount	Action
≤ 100 sats	Auto-approve
101–1000 sats	Auto-approve if within stated budget
1001–10000 sats	Ask user for confirmation
> 10000 sats	Always require explicit user approval

---

Error Handling

• If any CLI command returns {"success": false, "error": "..."}, handle the error gracefully.
• If wallet is not set up, run bash skills/bsv-pay/scripts/setup.sh first.
• If balance is insufficient for a payment, inform the user they need to fund the wallet.
• If the other agent doesn't respond with a protocol message, they may not have the bsv-pay skill installed.

---

Checking Balance

NODE_PATH=/home/dylan/a2a-bsv/node_modules node skills/bsv-pay/scripts/bsv-agent-cli.mjs balance

Returns {"success": true, "data": {"confirmed": 0, "unconfirmed": 0, "total": 0}} (amounts in satoshis).
