AgentWallet

Multi-chain wallet skill for AI agents. One seed phrase, all chains.

Quick Reference

Setup

New Wallet

User: "Create a new wallet"

Generates BIP-39 seed phrase, derives addresses for all chains. Shows seed ONCE with security warning.

Import Existing Wallet

User: "Import my wallet"

Response: "Add your seed phrase to .env as WALLET_SEED_PHRASE, then say 'Show my addresses' to verify."

No seed phrases in chat for imports - security first.

Environment

# Required for wallet operations
WALLET_SEED_PHRASE="your twelve word seed phrase goes here"

# Optional
NETWORK=testnet          # testnet (default) or mainnet
SOLANA_RPC=              # Custom Solana RPC (defaults to public)
BASE_RPC=                # Custom Base RPC (defaults to public)
ETH_RPC=                 # Custom Ethereum RPC (defaults to public)

Commands

Create Wallet

Run: node scripts/wallet.js create

Output format:

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
🔐 NEW WALLET GENERATED
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

⚠️  CRITICAL: Save this seed phrase securely!
    It will NOT be shown again.
    Anyone with this phrase can access your funds.

Seed Phrase:
┌────────────────────────────────────────────┐
│ word1 word2 word3 word4 word5 word6        │
│ word7 word8 word9 word10 word11 word12     │
└────────────────────────────────────────────┘

Your Addresses:
├─ Solana:   7xK9...mP4q
├─ Base:     0x7a3B...4f2E
└─ Ethereum: 0x7a3B...4f2E (same as Base)

Add to .env:
WALLET_SEED_PHRASE="word1 word2 word3 ..."

Network: TESTNET

Show Addresses

Run: node scripts/wallet.js addresses

Shows derived addresses without exposing seed.

Check Balance

Run: node scripts/wallet.js balance [chain]

• node scripts/wallet.js balance - All chains
• node scripts/wallet.js balance solana - Solana only
• node scripts/wallet.js balance base - Base only

Output includes native token + USDC balance per chain.

Transfer

Run: node scripts/wallet.js transfer

Examples:

• node scripts/wallet.js transfer solana USDC 10 7xK9fR2...
• node scripts/wallet.js transfer base ETH 0.01 0x7a3B...
• node scripts/wallet.js transfer solana SOL 0.5 7xK9fR2...

Supported tokens per chain:

• Solana: SOL, USDC
• Base: ETH, USDC
• Ethereum: ETH, USDC

Bridge (Cross-Chain)

Run: node scripts/wallet.js bridge

Bridges USDC between chains using Circle CCTP V2.

Examples:

• node scripts/wallet.js bridge base solana 10 - Bridge 10 USDC from Base to Solana
• node scripts/wallet.js bridge ethereum base 50 - Bridge 50 USDC from Ethereum to Base
• node scripts/wallet.js bridge solana ethereum 25 - Bridge 25 USDC from Solana to Ethereum

Note: Bridging takes 1-5 minutes (burn → attestation → mint). Requires USDC on source chain plus native tokens for gas.

Chain Info

Run: node scripts/wallet.js chains

Lists supported chains, networks, and USDC contract addresses.

Derivation Paths

All chains derive from single BIP-39 seed:

EVM chains share the same address (same derivation path).

Security Model

• One seed per agent - Each agent instance isolated
• Seed shown once - Only at creation, never logged
• Memory only - Private keys derived on-demand, never persisted
• No chat import - Seeds added via .env only (except generation)
