💰 Wallet Skill

Multi-chain wallet for EVM (6 chains) + Solana. Balances, transfers, signing, policy management.

Tools

Tool	Description
`wallet_info`	Get all wallet addresses
`wallet_balance`	EVM balance on a chain (DeBank)
`wallet_sol_balance`	Solana balance (Birdeye)
`wallet_get_all_balances`	All chains at once
`wallet_transfer`	Broadcast EVM tx (gas sponsored)
`wallet_sign_transaction`	Sign EVM tx (no broadcast)
`wallet_sign`	EIP-191 message signing
`wallet_sign_typed_data`	EIP-712 typed data signing
`wallet_transactions`	EVM tx history
`wallet_sol_transfer`	Broadcast Solana tx
`wallet_sol_sign_transaction`	Sign Solana tx (no broadcast)
`wallet_sol_sign`	Solana message signing
`wallet_sol_transactions`	Solana tx history
`wallet_get_policy`	Check policy status
`wallet_propose_policy`	Propose policy (sends to UI)

Key Facts

Gas is sponsored on EVM chains — user doesn't need ETH for gas
Policy default: OFF (allow-all). Only when user enables policy do transactions need UI confirmation
Supported EVM chains: ethereum, base, arbitrum, optimism, polygon, linea
Balance sources: DeBank (EVM), Birdeye (Solana), wallet-service (fallback)

Workflow

Check Balances

Single chain: wallet_balance(chain="base") or wallet_sol_balance()
All at once: wallet_get_all_balances()

Send Transaction (EVM)

Check balance: wallet_balance(chain=...)
Transfer: wallet_transfer(to=..., amount=..., chain_id=...)
Verify: wallet_transactions() or check balance again

Policy Management

Check: wallet_get_policy(chain_type="ethereum")
If user wants to enable: wallet_propose_policy(chain_type, rules, title, description)
User confirms in UI → policy applied

Standard Wildcard Policy (when needed)

rules = [
  {"name": "Deny key export", "method": "exportPrivateKey", "conditions": [], "action": "DENY"},
  {"name": "Allow all", "method": "*", "conditions": [], "action": "ALLOW"},
]

Gotchas

wallet_propose_policy sends SSE event to frontend — needs streaming context
DeBank/Birdeye keys are auto-injected by sc-proxy
wallet_balance requires chain param — use wallet_get_all_balances for discovery
Policy validation: eth_signTypedData_v4 requires at least one condition
For both EVM + Solana policy, call wallet_propose_policy TWICE
