No ERC-20 approval exists on Solana. How to bridge assets between chains is the check that the receiver is not a 0x address.
ETH is not what arrives
Solana Tether is not the Circle mint
WETH still needs POL to leave

Frequently asked questions
What is the best way to swap WETH from Polygon to USDT on Solana?
Sell 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619. Buy Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB. XAUConnect compares live routes and lets your own wallet sign.
Is the credit an ERC-20 I approve on Solana?
No. Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB is an SPL mint. Solana has no ERC-20 approval. You sell Polygon WETH at 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619, which Polygonscan can show. Solscan shows the mint in Phantom. A 0x address will not hold it. ETH is not WETH. Open Phantom and Solscan. There is no allowance step on that mint.
Will Tether pay Phantom?
No. Tether is not SOL. This quote does not buy So11111111111111111111111111111111111111112. Keep SOL in the destination wallet or the mint waits. There is no finish time for the bridge. POL pays only chain id 137. Bring a little SOL into Phantom before you need to transfer that Tether mint.
What if I wanted Circle USDC?
Leave this page. Circle on Solana is EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v. Tether and Circle are different issuers. Switch before you approve the Polygon WETH. The source contract is not Ethereum WETH. Do not start from Ethereum WETH. Circle on Solana is a different mint, and this page buys Tether.
