Frequently asked questions
What is the best way to swap USDT from BNB Chain to USDC on Avalanche C-Chain?
Approve 0x55d398326f99059fF775485246999027B3197955, the 18-decimal Tether peg. BscScan shows it on chain id 56.
How do I tell this USDC from a bridged copy?
Match 0xB97EF9Ef8734C71904D8002F8b6Bc66Dd9c48a6E on Snowtrace, chain id 43114. That is Circle's native USDC on C-Chain. A bridged copy can share the ticker and still be the wrong token. The input was 0x55d398326f99059fF775485246999027B3197955 on BscScan. You need AVAX afterward. The X-Chain is not the network.
Does this keep my balance in Tether?
No. You sell the Tether peg and receive Circle USDC. If a desk asked for Tether on C-Chain, this route is the wrong tool. BscScan and Snowtrace will not show one shared balance. Gas out is BNB on chain id 56. Gas on C-Chain is AVAX, and USDC cannot pay it.
Can I move the USDC with no AVAX in the wallet?
No. Circle USDC at 0xB97EF9Ef8734C71904D8002F8b6Bc66Dd9c48a6E does not pay gas. AVAX does, on chain id 43114. Snowtrace can show the token while a transfer fails. BNB left on BNB Chain does not help, and an X-Chain AVAX balance does not either. Add AVAX on C-Chain.
