Address (Wallet Address)
A unique string of characters that identifies where cryptocurrency can be sent, like an account number for your wallet.
A wallet address looks something like 0x742d35Cc6634C0532925a3b844Bc9e7595f2bD78 on Ethereum, or a shorter string on other chains. It's derived from your public key and is safe to share. Anyone can send USDC to your address, but only you (with your private key) can send USDC from it.
Different blockchains have different address formats. An Ethereum address won't work on Solana and vice versa. This is a common source of mistakes. Always double-check that you're sending to an address on the correct network.
Most wallets let you copy your address with one tap and display it as a QR code. When receiving USDC, you give the sender your address and tell them which network to use. Sending to the wrong address is usually irreversible, so always verify before confirming.
