Frequently asked questions
What is the best way to swap WETH from Base to USDC on Solana?
Approve 0x4200000000000000000000000000000000000006 on Base, chain 8453. Basescan shows that ERC-20, and ETH pays the allowance.
Does Solana ask me to approve USDC?
No. Solana has no ERC-20 approval. You approve Base WETH at 0x4200000000000000000000000000000000000006 on chain 8453, and that costs ETH. The USDC you receive is the mint EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v, checked on Solscan. A token account on Solana is not an allowance. Phantom must hold the mint, and MetaMask cannot.
Can MetaMask receive this USDC?
No. MetaMask can hold the WETH you spend and cannot hold the SPL mint. Use Phantom or another Solana wallet, and paste that address, not a 0x address. Solscan is where the Circle mint should appear. There is no ERC-20 step on the Solana side.
Is this Tether's mint?
No. Tether on Solana is Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB. This route delivers Circle's mint. If the payment instruction says USDT, stop. SOL, the fee coin, is also a different mint, So11111111111111111111111111111111111111112, and this quote does not buy it. If you needed SOL for fees, that is a different route.
