Authentication & Identity — Handle email, SMS, social, and passkey logins. Link multiple social profiles to a single wallet address using initiate_auth and link_profile.
Wallet Management — Retrieve authenticated user details, search for users by address or email, and pre-generate wallets for new users via get_user_details and pregenerate_wallet.
Smart Contract Interaction — Execute read-only multicalls or state-changing transactions across any supported chain using read_contract and write_contract.
Event Monitoring — Query historical contract events with advanced filtering for data analysis using query_events.

FAQ

Frequently asked questions

Can I read data from a smart contract without paying gas?

Yes! Use the read_contract tool. It performs read-only calls (multicall) to the blockchain, which do not require gas or state changes.

How do I start an authentication flow for a new user?

You can use the initiate_auth tool by specifying the method (email, sms, etc.) and the user's identifier. Then, use complete_auth with the verification code to finish the login.

Can I find a user's profile if I only have their wallet address?

Absolutely. Use the get_user_details tool and provide the address parameter. The agent will return any associated user IDs, emails, or phone numbers linked to that wallet in your project.
