Swap ETH from Base to USDT on Solana

Swap ETH from Base to USDT on Solana. You sell native ETH on Base and you receive Tether's SPL USDT on Solana.

The input is Base ETH, chain 8453, placeholder 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, on Basescan as the account balance. Leave a fee. No approval applies to that coin. The output mint is Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB. Solscan shows it. It is Tether, not Circle's Solana USDC at EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v. Phantom holds SPL tokens. MetaMask does not. Solana has no ERC-20 approval. SOL, not USDT, pays Solana fees.

ETH leaves Base. USDT is what can arrive on Solana.

Tether's mint, not Circle's

Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB is the USDT mint. A payment that expected EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v will not clear. Ethereum Tether at 0xdAC17F958D2ee523a2206206994597C13D831ec7 is a third asset on chain 1. Tickers do not cross those boundaries. Read the mint on Solscan before you tell anyone you paid them.

The send spends the Base fee coin

Keep ETH for the chain 8453 fee. WETH will not be picked up. You are not wrapping, and you are not delivering ETH on Solana. You are selling ether for a dollar mint on another network. If Base apps still need ETH, the sale works against that.

No allowance on Solana

Do not look for an approve transaction on Solscan for this receive. SPL transfers do not use ERC-20 allowances. The Solana wallet may need a token account for the mint. That creation is not an approval of a spender. Trade on Solana is the receiving environment. No bridge clock is stated.

Where the result cannot appear

It cannot appear in MetaMask. It cannot appear as Ethereum USDT. It cannot appear as SOL unless you chose the SOL mint So11111111111111111111111111111111111111112, which is a different route. Basescan shows ETH leaving. Solscan shows the Es9v mint. Decline a weak minimum. SOL pays Solana fees and is not included with this Tether mint, so Phantom still needs a little SOL of its own.

Frequently asked questions

What is the best way to swap ETH from Base to USDT on Solana?

The input is Base ETH, chain 8453, placeholder 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, on Basescan as the account balance. Leave a fee.

Is Solana USDT the Ethereum Tether contract?

No. Ethereum Tether is 0xdAC17F958D2ee523a2206206994597C13D831ec7. This route delivers the SPL mint Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB, which you check on Solscan. Circle's Solana USDC is a different mint. The source is native ETH on Base, chain 8453, not a token approval. Phantom must hold the SPL mint, and Solscan is where you verify it.

Which wallet receives the USDT?

A Solana wallet such as Phantom. MetaMask can sign away the Base ETH and cannot store the SPL mint. There is no ERC-20 approval on Solana. Paste a Solana address, not a 0x address, as the receiver. Then read Solscan for Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB. A 0x address is not a Solana receiver.

Does the USDT include SOL for fees?

No. SOL pays Solana fees. USDT does not. Selling Base ETH does not deliver a SOL balance for you. The wrapped SOL mint is a different route. Keep SOL in Phantom if you need to move the Tether after it arrives, and keep a little ETH on Base for the send.
