name: agent-wallet description: Multi-chain wallet management for AI agents. Create wallets, check balances, transfer tokens (USDC/native), and bridge cross-chain. Use when agents need to send/receive payments, check funds, or manage crypto wallets. Supports Solana, Base, and Ethereum. Trigger phrases include "create wallet", "check balance", "send USDC", "transfer", "my addresses", "wallet status".

AgentWallet

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

Quick Reference

Command	Example
Create wallet	"Create a new wallet"
Show addresses	"Show my addresses" / "What's my wallet?"
Check balance	"Check my balance" / "How much USDC do I have?"
Transfer	"Send 10 USDC to 0x..." / "Transfer 5 SOL to ..."
Bridge	"Bridge 10 USDC from Base to Solana"
Chain info	"What chains are supported?"

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 <chain> <token> <amount> <recipient>

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 <from-chain> <to-chain> <amount>

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:

Chain	Path	Standard
Solana	m/44'/501'/0'/0'	Solana/Phantom
EVM (Base/Eth)	m/44'/60'/0'/0/0	BIP-44 Ethereum

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)

Error Handling

Error	Cause	Fix
"WALLET_SEED_PHRASE not set"	Missing env var	Add seed to .env
"Invalid seed phrase"	Wrong format	Must be 12 or 24 words
"Insufficient balance"	Not enough funds	Check balance first
"Invalid address"	Wrong format	Verify recipient address
