Swap WETH from Ethereum to USDT on Solana
Swap WETH from Ethereum to USDT on Solana. You send wrapped ether from Ethereum and you receive Tether USDT on Solana, not Circle USDC and not SOL.
The contract you approve is 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2. Etherscan lists it on chain id 1. Gas for that approval is native ETH, and blocks are about 12 seconds. Tether on Solana is the mint Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB. Match it on Solscan in Phantom or Solflare. Solana will not ask for an ERC-20 approval. You still need SOL beside the USDT.
WETH is not the coin that pays gas
Tether arrives without an SPL approval
Native ETH and Circle USDC are other pages

Frequently asked questions
What is the best way to swap WETH from Ethereum to USDT on Solana?
The contract you approve is 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2. Etherscan lists it on chain id 1.
Which explorer shows the USDT, Etherscan or Solscan?
Etherscan shows WETH leaving Ethereum at 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2. Solscan shows Tether arriving at Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB. They are different networks. Phantom or Solflare is the wallet for the mint. There is no ERC-20 approval on Solana. You need SOL in that wallet after the USDT shows up.
What if my WETH approval is already set?
An existing approval for the amount you want can be enough, and you may only sign the swap. Check it on Etherscan rather than assuming. You still need ETH for gas on chain id 1. The approval does not lock the USDT quote. If the quote expired, request a new one before you sign the swap.
Can this page pay Circle USDC if Tether liquidity is poor?
No. The payout mint is Tether, Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB. Circle USDC is a different page. If the minimum USDT on this quote is worse than you will take, do not sign and do not assume the route will switch issuers for you. WETH would still be the asset you sold.
