  • 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.

Read the total supply of the contract 0x123... on chain 1.

I've executed the `read_contract` call. The total supply for the contract on Ethereum (Chain ID: 1) is 1,000,000 tokens.

Start an email authentication for dev@example.com.

I've triggered `initiate_auth` via email for dev@example.com. The user should receive a verification code shortly. Please provide the code to `complete_auth` when ready.

Search for user details associated with address 0xAbc123...

Using `get_user_details`, I found that this address is linked to User ID 'user_987' with the verified email 'admin@web3app.com'.

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