description: Check balances, send ETH/tokens, and interact with smart contracts on-chain.
triggers:
  - wallet
  - balance
  - send eth
  - send token
  - transfer
  - send max
  - send all
  - check balance
  - my address
  - smart contract
  - call contract
  - swap
  - on-chain
  - erc20
  - nft
priority: 90
inputs:
  - recipient address
  - amount (numeric or max)
  - token contract address
  - ABI fragment
outputs:
  - wallet address
  - balance
  - transaction hash
  - contract call result
safety_notes:
  - All send/write operations ALWAYS require explicit Telegram approval
  - Read-only contract calls (view/pure) execute freely
  - Never expose the private key in responses

Wallet Skill

Use this skill for anything involving the agent's ETH wallet, on-chain queries, or smart contract interaction.

Tools Available

wallet_address — Returns the agent's public address. No params needed.

wallet_balance — Checks ETH balance. Pass an optional token (ERC-20 contract address) to check a specific token.

wallet_send — Sends ETH or an ERC-20 token. Params: to, amount, optional token. Always requires approval.

wallet_call_contract — Calls any smart contract function. Params: contract_address, abi (JSON ABI fragment), function_name, optional args and value. Write calls require approval; reads are free.

Guidelines

  • •When the user asks about balances, use wallet_balance.
  • •When the user asks to send crypto, pass only to, amount (or max), and optional token into wallet_send.
  • •Do not manually calculate max-send amount in chat logic. Use amount: "max" and let the tool resolve it.
  • •Do not simulate approval text. wallet_send triggers the real approval request flow and broadcast path.
  • •For smart contract interactions, construct the minimal ABI fragment needed for the specific function call.
  • •Never reveal the private key or seed phrase.
  • •If you don't know a token's contract address, use the browser to look it up first.
  • •Always confirm transaction details with the user before calling any write function.

Common Patterns

Check ETH balance: Call wallet_balance with no params.

Check USDC balance on Base: Call wallet_balance with token: "0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913" (USDC on Base).

Send ETH: Call wallet_send with to and amount.

Send max ETH: Call wallet_send with to and amount: "max".

Read a contract: Call wallet_call_contract with the contract address, a minimal ABI fragment like [{"name":"balanceOf","type":"function","stateMutability":"view","inputs":[{"name":"account","type":"address"}],"outputs":[{"name":"","type":"uint256"}]}], the function name, and args.
