Swap USDT from Solana to POL on Polygon

Swap USDT from Solana to POL on Polygon. Tether's SPL mint leaves Solana, and native POL is what can arrive to pay gas on chain id 137.

You send Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB. Phantom signs, Solscan shows the mint, and there is no ERC-20 approval. POL is 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE on Polygon. Polygonscan shows the native row. This is not WETH at 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619 and not Circle USDC at 0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359. Ethereum gas is ETH on chain id 1, not this POL.

USDT leaves Solana. POL is what can arrive on Polygon.

You are refilling Polygon, not buying a dollar or a wrapper

The sentinel means native POL. Do not import it. If the wallet still prints MATIC, treat that as a stale label for the same gas role, and confirm the balance on Polygonscan rather than by adding a random contract. WETH and USDC are different routes. This page is wrong when the next contract wants those ERC-20s. It is right when the next transaction simply will not broadcast.

Chain id 137 is not chain id 1

Ethereum takes about 12 seconds per block and uses Etherscan. POL will not pay a mainnet fee. Polygon is the only place this arrival spends. An EVM wallet parked on Ethereum will show nothing and invite you to send the Tether mint again. Switch networks before you call the hop a failure.

SOL pays for the request, POL pays for everything after

The POL you hope to receive cannot fund the Phantom transaction. Keep native SOL. The Tether mint will not pay it. There is no ERC-20 approval to revoke on Solscan. MetaMask cannot see the mint. After the credit, chain id 137 should show POL on the native line. That line is the fee budget for the Polygon actions you came to do.

Skip the conversion if you only needed Tether to stay Tether

Polygon already has Tether at 0xc2132D05D31c914a87C6611C10748AEb04B58e8F if dollars were the point, and Solana already has the mint you are spending. Buying POL takes price risk. Do it when you have Polygon transactions queued. The minimum POL should cover those transactions plus a retry. This page does not promise when Polygonscan will update.

Frequently asked questions

What is the best way to swap USDT from Solana to POL on Polygon?

You send Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB. Phantom signs, Solscan shows the mint, and there is no ERC-20 approval.

Is the arrival WETH or native POL?

Native POL, quoted as 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE on Polygon, chain id 137. WETH is 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619 and is a different route. Tether's mint left Solana. Check the POL row on Polygonscan, not a token import of the sentinel. POL is what pays gas. Confirm the contract on the explorer before you sign.

Can Phantom hold the POL?

No. Phantom holds Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB and signs with SOL. POL is native gas on chain id 137 in an EVM wallet. There is no ERC-20 approval on the Solana mint. Solscan shows the debit. Polygonscan shows the credit. Keep SOL so the debit can happen. Keep the destination gas token or the arrival cannot move.

Will this POL pay fees on Ethereum?

No. Ethereum is chain id 1, about 12 second blocks, explorer Etherscan, fee coin ETH. This route funds Polygon only. If mainnet gas was the shortage, you are on the wrong page. Read the minimum POL and do not sign if it will not cover the Polygon transactions you need.
