Overview
USDC is Circle's stablecoin deployed across multiple blockchain ecosystems. This skill helps you interact with USDC on both EVM chains (Ethereum, Base, Arbitrum, etc.) and Solana. It covers balance checks, transfers, approvals, and transfer verification.
Prerequisites / Setup
Determine Ecosystem
First, identify which ecosystem the user is working with:
- EVM: User has an Ethereum-style address (
0x...) or mentions Ethereum, Base, Arbitrum, Polygon, etc. - Solana: User has a base58 address or mentions Solana, Devnet, Phantom, Solflare, etc.
- Unclear: Ask which ecosystem before proceeding.
