Swap WETH from Ethereum to USDC on Solana
Swap WETH from Ethereum to USDC on Solana. You send wrapped ether from Ethereum and you receive Circle USDC on Solana.
WETH is the ERC-20 at 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2. You approve it. Etherscan records that approval on chain id 1, where gas is still native ETH and blocks take about 12 seconds. Circle's SPL USDC is EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v. Match the mint on Solscan. Phantom or Solflare holds it. Solana has no ERC-20 approval. Keep SOL there so the USDC can move later.
Approve the wrapper, pay gas in ETH
Circle on Solana is a mint, not a 0x token
Unwrapping is the wrong tool here
The minimum USDC is the only floor

Frequently asked questions
What is the best way to swap WETH from Ethereum to USDC on Solana?
WETH is the ERC-20 at 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2. You approve it. XAUConnect compares live routes and lets your own wallet sign.
Why do I need ETH if I am already paying with WETH?
WETH is the asset being sold, at 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2. Gas on Ethereum is native ETH. Etherscan will show the approval and the swap as ETH-paid transactions. The USDC you receive is EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v on Solscan. Without ETH, the approval cannot be mined. Without SOL later, the USDC cannot be sent.
Is Solana USDC the same contract as Ethereum USDC?
No. Ethereum USDC is an ERC-20. This payout is the SPL mint EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v, which you check on Solscan, not on Etherscan. Both are Circle's dollar token, on different networks. Phantom or Solflare holds the Solana one. There is no ERC-20 approval on that side.
Can I skip the approval and send WETH like native ETH?
No. Native ETH uses the gas-coin marker and a different page. This route can move WETH only after you approve 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2. The approval is not the bridge. When it confirms, you still sign the swap against a fresh quote. A stale minimum is not a promise.
