Swap AVAX from Avalanche C-Chain to USDT on Solana

Swap AVAX from Avalanche C-Chain to USDT on Solana. Native AVAX leaves C-Chain, and Tether's SPL mint is what can arrive on Solana.

The AVAX sentinel is 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE on chain id 43114. Snowtrace shows native gas, not an approval. Tether on Solana is Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB. Solscan is the explorer for that mint. Phantom holds the token account. There is no ERC-20 approval on Solana, and MetaMask cannot be where you look for the credit. Keep AVAX for the C-Chain fee.

Diagram for Swap AVAX from Avalanche C-Chain to USDT on Solana
AVAX leaves Avalanche C-Chain. USDT is what can arrive on Solana.

Tether's mint is the whole point of the arrival

Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB is not Circle's EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v. Programs that settle in Circle will ignore a Tether balance, and the reverse is true. This page is the wrong route when the Solana instruction names the Circle mint. It is also the wrong route when you wanted SOL itself, which is the wrapped mint So11111111111111111111111111111111111111112, not a dollar.

The source wallet and the destination wallet are not a network toggle

Spending AVAX is an EVM signature on C-Chain. Receiving the mint is a Solana account. MetaMask can do the first and cannot do the second. Phantom can do the second and cannot sign chain id 43114 as if it were an Ethereum chain. Solana is the side you are entering. Solscan will not index your leftover AVAX, and Snowtrace will not index the mint.

Fee coins on both ends, and USDT is neither

Leave AVAX on chain id 43114 or the send never broadcasts. X-Chain is the wrong Avalanche chain. On Solana, hold native SOL or the new Tether cannot move. The route does not deliver the gas sentinel as a Solana concept. 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE stops being meaningful the moment you are looking at Phantom. Plan the SOL fee before you need to forward the mint.

A C-Chain stable is quieter if Solana was optional

AVAX to Tether can be done on C-Chain when the creditor, the pool, or your own books are still there. Cross only for the SPL mint. The minimum USDT is the number that matters. A thin quote can cost more than the AVAX fee you were trying to escape. This page does not turn a block on either chain into an arrival time.

Frequently asked questions

What is the best way to swap AVAX from Avalanche C-Chain to USDT on Solana?

The AVAX sentinel is 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE on chain id 43114. Snowtrace shows native gas, not an approval.

Does AVAX arrive as Circle USDC on Solana?

No. Native AVAX leaves C-Chain and Tether's mint Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB is what can arrive. Circle's mint is EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v. Check Solscan and hold the token in Phantom. If the program wants Circle, this route is the wrong mint. Confirm the contract on the explorer before you sign.

Do I approve the AVAX sentinel first?

No. 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE is native gas on Avalanche C-Chain, chain id 43114, shown on Snowtrace. There is no ERC-20 approval for it, and there is none on Solana either. Leave enough AVAX to pay the fee. X-Chain balances cannot sign this send. Keep the destination gas token or the arrival cannot move.

Why can Phantom show USDT and still fail a transfer?

Because Solana fees are native SOL, and the USDT mint does not pay them. A new wallet can hold Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB and have nothing for rent or fees. Fund a little SOL before you move the mint. MetaMask will not show this balance at all. The quote minimum is the floor, and a thin floor is a reason to stop.
