Frequently asked questions
What is the best way to swap WETH from Arbitrum One to USDT on Solana?
Spend 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1 on Arbitrum One. Arbiscan, chain id 42161, not Nova. XAUConnect compares live routes and lets your own wallet sign.
Which USDT mint arrives in Phantom?
Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB. Check it on Solscan. You spend WETH at 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1 on Arbitrum One. Arbitrum Tether is not the credit. There is no ERC-20 approval on Solana, and the recipient cannot be a 0x address. Confirm that address on the explorer before you sign, and refresh the quote if it has expired.
Why do I need ETH to sell WETH?
Chain id 42161 charges native ETH, sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. WETH cannot pay it. SOL cannot pay it. If that ETH row is empty, the approval cannot be signed. A slot near 400 milliseconds on Solana does not remove the source fee. Nova is the wrong chain.
Does wrapped ether arrive as wrapped SOL?
No. The output mint is Tether, not So11111111111111111111111111111111111111112. Starting with WETH does not preserve an ETH ticker on Solana. If you wanted SOL, open the route that names that mint. Read the quote before you approve 0x82aF. Confirm that address on the explorer before you sign, and refresh the quote if it has expired.
