What happens if a transaction is too large?

If a transaction exceeds your defined approval threshold, the agent will pause and wait for your explicit manual confirmation before proceeding.

Is it safe to use my main wallet with this skill?

No, this skill is designed to use a separate, sandboxed wallet with a new seed phrase to ensure your main assets remain isolated and secure.

Does this work with wallets other than MetaMask?

Currently, this skill is specifically optimized for the MetaMask browser extension and does not support other wallet providers.

Can I limit how much the agent spends?

Yes, you can set daily spend limits and per-transaction caps in the permissions.json file to prevent unauthorized or excessive spending.

Which blockchains are supported?

The skill supports any chain compatible with MetaMask, provided you add the chain IDs to your allowedChains configuration.
