# Aptos Claude Agent

Aptos blockchain interaction with game-theoretic decision analysis.

## When to Use

- Check APT wallet balances
- Transfer APT tokens
- Swap tokens on DEX (Liquidswap, etc.)
- Stake APT
- Call Move view functions
- Process natural language blockchain intents
- Query NFT/token collections
- Interact with multisig accounts

## Setup

MCP server configured in `~/.mcp.json`:
```json
{
  "aptos": {
    "command": "node",
    "args": ["/path/to/aptos-claude-agent/dist/mcp/server.js"],
    "env": {
      "APTOS_NETWORK": "mainnet",
      "APTOS_PRIVATE_KEY": "${APTOS_PRIVATE_KEY}"
    }
  }
}
```

## Available MCP Tools

| Tool | Description |
|------|-------------|
| `aptos_balance` | Get wallet balance |
| `aptos_transfer` | Transfer APT (requires approval) |
| `aptos_swap` | Swap tokens on DEX (requires approval) |
| `aptos_stake` | Stake APT (requires approval) |
| `aptos_view` | Read-only view function call |
| `aptos_intent` | Process natural language intent |
| `aptos_approve` | Approve/reject pending decision |
| `aptos_pending` | List pending decisions |

## Security Model

1. **Simulation First**: All transactions simulated before execution
2. **Approval Required**: Every state-changing operation needs explicit approval
3. **Game-Theoretic Analysis**: Transactions modeled as open games
4. **Wallet Validation**: ALWAYS validate key→address before funding

## CRITICAL: Wallet Derivation Safety

**NEVER use `derive-resource-account-address` for wallet creation.**

### Correct Workflow
```bash
# 1. Generate key
aptos key generate --output-file my_key

# 2. Derive address FROM PRIVATE KEY
aptos init --private-key-file my_key --network mainnet --profile my_wallet

# 3. VALIDATE before funding
just aptos-validate "PRIVATE_KEY" "EXPECTED_ADDRESS"

# 4. Only fund AFTER validation passes
```

### What Can Go Wrong
- Using `derive-resource-account-address` with pubkey = **PERMANENT FUND LOSS**
- Resource accounts need signer capabilities from source account
- If key doesn't match address, funds are unrecoverable

### Validation
Run `just aptos-validate-all` to verify all configured wallets before any funding operation.

## Common View Function Patterns

### Check APT Balance
```
aptos_view(
  functionId: "0x1::coin::balance",
  typeArgs: ["0x1::aptos_coin::AptosCoin"],
  args: ["0xADDRESS"]
)
```

### Check Token Balance (Legacy)
```
aptos_view(
  functionId: "0x3::token::balance_of",
  typeArgs: [],
  args: ["0xOWNER", { token_data_id: {...}, property_version: 0 }]
)
```

### Check Stake
```
aptos_view(
  functionId: "0x1::stake::get_stake",
  typeArgs: [],
  args: ["0xVALIDATOR_POOL"]
)
```

### Check Delegation
```
aptos_view(
  functionId: "0x1::delegation_pool::get_stake",
  typeArgs: [],
  args: ["0xPOOL", "0xDELEGATOR"]
)
```

## Game-Theoretic Features

### Nashator Analysis
Computes deviation incentives for transactions:
- **LAX monoidal** (`fire`): Actual execution
- **STRONG monoidal** (`exec`): Simulation only

### Bisimulation Self-Play
Explores alternatives via attacker/defender games. Equilibrium detected when `|utility - quality| < 0.15`.

### Risk Visualization
Decisions map to colors via deterministic LCG:
- **HOT ZONE [160-220]**: High-risk indices
