Swap USDC from Base to AVAX on Avalanche C-Chain
Swap USDC from Base to AVAX on Avalanche C-Chain. Circle USDC leaves Base, and native AVAX arrives on the C-Chain.
Spend 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913, Circle's USDC on Base, chain 8453. Basescan shows it, and you pay ETH for the allowance and the send. Receive native AVAX on chain 43114. Quotes label it 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. Snowtrace shows AVAX on the account, not as a token contract. This is the C-Chain, not the X-Chain. Tether at 0x9702230a8ea53601f5cd2dc00fdbc13d4df4a8c7 is a different result. You are buying the fee coin.

Frequently asked questions
What is the best way to swap USDC from Base to AVAX on Avalanche C-Chain?
Spend 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913, Circle's USDC on Base, chain 8453. Basescan shows it, and you pay ETH for the allowance and the send.
Does this AVAX arrive on the X-Chain?
No. It arrives as native AVAX on the C-Chain, chain 43114, shown on Snowtrace as the account balance. The quote writes it as 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. The X-Chain and the P-Chain are different systems. An export from C-Chain to X-Chain would be another step, not this route.
Is AVAX an ERC-20 I must approve on arrival?
No. Native AVAX is the gas coin. You do not approve it to hold it. You did approve Circle USDC on Base, at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913, so the router could take the input. That allowance was chain 8453 and cost ETH. AVAX on the C-Chain is a separate coin and does not pay the Base fee.
I needed USDT, not AVAX. Is this close?
No. Tether on the C-Chain is 0x9702230a8ea53601f5cd2dc00fdbc13d4df4a8c7. Circle USDC there is 0xB97EF9Ef8734C71904D8002F8b6Bc66Dd9c48a6E. This page delivers the gas coin. If the order was a dollar, leave it. AVAX will not satisfy a stablecoin whitelist. If the invoice says USDT or USDC, pick the dollar route instead of the gas coin.
