Check and send USDC across EVM chains and Solana.
What it does
Checks USDC balances, sends payments, manages spending approvals, and verifies transfers on EVM chains and Solana.
When to use it
Use for single-chain USDC balance checks, payments, approvals, or low-level transfer control.
How to use it
Give it a USDC operation; it queries blockchain state or, after explicit confirmation, submits the transaction and reports its confirmation.

What you need · 2
EVM transfers and spending approvals use a private key, recommended through PRIVATE_KEY; reading a local key file is an alternative. Read operations need no private key.
Solana transfers use a private key, recommended as a JSON byte array in SOLANA_PRIVATE_KEY; Base58 conversion and a local key file are alternatives. Read operations need no private key.
