Swap USDC from Solana to AVAX on Avalanche C-Chain
Swap USDC from Solana to AVAX on Avalanche C-Chain. Circle's SPL mint leaves Solana, and native AVAX is what can arrive to pay gas on C-Chain. X-Chain AVAX is not this balance.
You send EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v. Phantom signs, Solscan records it, and there is no ERC-20 approval. AVAX is 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE on chain id 43114. Snowtrace shows the native row, not a token import of the sentinel. This is not WETH, not a dollar, and not ETH on Ethereum, chain id 1, about 12 second blocks, Etherscan.
C-Chain gas is the arrival, and the sentinel is how it is quoted
SOL has to pay before any AVAX exists
Snowtrace lag is not a reason to send twice
Buy AVAX when C-Chain transactions are queued

Frequently asked questions
What is the best way to swap USDC from Solana to AVAX on Avalanche C-Chain?
You send EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v. Phantom signs, Solscan records it, and there is no ERC-20 approval.
Is the AVAX from Solana USDC an X-Chain balance?
No. Native AVAX arrives on C-Chain, chain id 43114, quoted as 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. X-Chain and P-Chain will not show it. Circle's mint left Solana. Check the AVAX row on Snowtrace, not a token import. This AVAX pays C-Chain gas. Keep the destination gas token or the arrival cannot move.
Can this AVAX pay Ethereum fees?
No. Ethereum is chain id 1, about 12 second blocks, explorer Etherscan, fee coin ETH. This route funds C-Chain only. SOL paid the Phantom side. There is no ERC-20 approval on EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v. Keep SOL so the mint can leave. The quote minimum is the floor, and a thin floor is a reason to stop.
What if I needed USDT instead of AVAX?
Use the USDT route. Tether on C-Chain is 0x9702230a8ea53601f5cd2dc00fdbc13d4df4a8c7, and native AVAX will not satisfy that contract. This page is for gas. Read the minimum AVAX only if C-Chain fees are what you are trying to buy. A block interval is not a delivery time for the bridge.
