Documentation Overview

dingdawg-agent-wallet — live demo

Shows governed agent wallet enforcement in action: allow, deny, step-up, allowlist — all in 5 seconds. No API keys. No blockchain required.

What it demonstrates

Code

▶ provision_wallet
  wallet_id:    demo-wallet-abc123
  daily_cap:    $200 USDC
  per_call_cap: $100 USDC

▶ governed_spend — $25 USDC (allowed)
  ✓ AUTHORIZED
  receipt_id:      6aba84a6-...
  daily_remaining: $175 USDC
  next_step:       wallet.sendToken({ assetId: "usdc", amount: "25", destination: "0xVendorABC123" })

▶ governed_spend — $150 USDC (exceeds per-call cap)
  ✗ DENIED
  reason:      Amount 150 USDC exceeds per-call cap 100 USDC
  receipt_id:  cd7a7aa8-... (denial is logged too)

▶ governed_spend — $75 USDC (step-up required)
  ⚠ STEP-UP REQUIRED
  reason: Amount 75 USDC > step-up threshold 50 USDC — MFA required
  fix:    Pass approval_token from your authorization flow

▶ governed_spend — unknown recipient (not in allowlist)
  ✗ DENIED
  reason: Recipient 0xUnknownAddress not in allowlist

▶ wallet_audit
  chain_verified: true ✓
  total_receipts: 5
  [17:02:18] DENY  $10 USDC    governed_spend
  [17:02:18] DENY  $75 USDC    governed_spend
  [17:02:18] DENY  $150 USDC   governed_spend
  [17:02:18] ALLOW $25 USDC    governed_spend
  [17:02:18] ALLOW              provision_wallet

Every action — allow AND deny — produces an immutable receipt. chain_verified: true means the full chain is tamper-evident — any modification is detectable.

Run it

bash

git clone https://github.com/DingDawg/agent-wallet-demo
cd agent-wallet-demo
npm install
node demo.mjs

The package

dingdawg-agent-wallet — 5 MCP tools that wrap any agent wallet with policy enforcement and an immutable audit trail.

Terminal

npm install dingdawg-agent-wallet

Tool	What it does
`provision_wallet`	Create wallet with spend policy (daily cap, per-call cap, allowlist)
`governed_spend`	Policy check → authorize → immutable receipt
`governed_receive`	Accept payment with tamper-evident receipt
`wallet_policy`	Update limits and allowlists at runtime
`wallet_audit`	Full receipt chain — `chain_verified: true`

Coinbase AgentKit gives your agent a wallet. DingDawg gives it a conscience.

Why this matters

AI agents can now hold USDC and spend autonomously. The infrastructure exists. What doesn't: who enforces what the agent is allowed to spend, on what, for whom — and proves it happened correctly.

governed_spend authorizes then returns the exact agentkit_call SDK method to execute on-chain
Every denial is logged — you can prove what your agent didn't do
chain_verified: true means the audit trail is tamper-evident — any modification is detectable
