What wallet does

The skill runs Python functions from core.skill_tools.wallet through bash. They read balances and transaction history, broadcast transfers, or sign messages. To propose a wallet policy, it calls frontend_action; the user confirms in the UI. The scripts do not register wallet tools.

For a user's wallet, the agent can retrieve its address with get_user_wallets() and pass it to a balance check. The agent does not hold the user's keys, so the user signs their transactions in the UI. EVM transfers sponsor gas by default, with user-paid gas as a fallback. EVM transfer amounts must be supplied in wei, so check the unit before sending.

What it helps with

  • check a balance on an EVM chain or Solana
  • review wallet transaction history
  • send an EVM or Solana transaction
  • sign a message or typed data
  • check or propose a wallet policy

Example prompts for the agent

  • Check my balance on Base and show the address of my wallet.
  • Send an EVM transfer to this address, then check the transaction history.
  • Check the current EVM wallet policy and propose a replacement for me to confirm in the UI.
