Swap SOL from Solana to POL on Polygon

Swap SOL from Solana to POL on Polygon. SOL leaves Solana, and native POL is what can arrive. You exchange one fee coin for the fee coin on chain id 137.

The quote names So11111111111111111111111111111111111111112, the wrapped SOL mint. Phantom signs, Solscan shows it, native SOL pays the source fee, and there is no ERC-20 approval. POL is 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE on Polygon. Polygonscan shows the native balance. This is not WETH, not a dollar, and not ETH on Ethereum, chain id 1, where blocks are about 12 seconds and the explorer is Etherscan.

The sentinel is POL, and the mint is SOL

Do not paste So11111111111111111111111111111111111111112 into an EVM field, and do not paste 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE into Phantom. They are not two spellings of one coin. Read the POL row on chain id 137. If the wallet still says MATIC, confirm on Polygonscan instead of importing a token to chase the old ticker. WETH at 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619 will not pay the fee this POL is for.

You cannot buy POL with a SOL balance of zero

Native SOL pays Phantom. The wrapped mint in the quote does not remove that. Leave a remainder. MetaMask cannot tell you the debit happened. Solscan can. The POL you receive cannot travel back in time to pay that debit. Plan the fee before you size the trade.

Ethereum gas is a different request

Chain id 1 uses ETH and Etherscan. This route never credits it. Polygon is the network that spends POL. A friend who asked for mainnet gas will still be stuck if you stop here. The bridge has no clock on this page. Watch the destination address. Do not sign a second time because the first wallet, still on Solana, looks empty.

Buy POL only for transactions you will send on Polygon

If you need SOL fees, selling SOL is backwards. If you need USDC or USDT, a dollar route avoids POL's price. If you need WETH, the wrapper route matches the contract. The minimum POL should cover the actions you already intend, including a retry. Refuse a floor that leaves the new chain as stuck as the old one.

Frequently asked questions

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

The quote names So11111111111111111111111111111111111111112, the wrapped SOL mint. Phantom signs, Solscan shows it, native SOL pays the source fee, and there is no ERC-20 approval.

Are the SOL mint and the POL sentinel interchangeable?

No. SOL is So11111111111111111111111111111111111111112, an SPL mint on Solscan, held in Phantom, with no ERC-20 approval. POL is 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE on Polygon, chain id 137, shown on Polygonscan. Native SOL still pays the source fee. Neither coin pays the other chain. Switch the wallet to the destination chain before you judge the balance.

Can this POL pay Ethereum fees?

No. Ethereum is chain id 1, about 12 second blocks, explorer Etherscan, fee coin ETH. POL pays chain id 137 only. If mainnet gas was the goal, this route is the wrong destination. Switch the EVM wallet to Polygon before you look for the credit.

What if the app wants WETH, not POL?

Use the WETH route. Native POL will not satisfy 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619. This page is for gas. Leave enough SOL to sign, and check the native POL row on Polygonscan rather than a token list that asks you to import the sentinel. Do not send a second time while the first transfer is still open.
