Swap USDC from Polygon to ETH on BNB Chain
Swap USDC from Polygon to ETH on BNB Chain. Circle USDC leaves Polygon. Binance-Peg ETH is what can arrive on BNB Chain. That token is not native ether and it will not pay BNB Chain fees.
Sell 0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359. Buy 0x2170Ed0880ac9A755fd29B2688956BD959F933F8. WETH on Ethereum is 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 and is not involved. Polygonscan shows the USDC. BscScan shows the peg. Chain id 56 charges BNB, with blocks around 3 seconds. How cross-chain bridges work is useful if the ticker ETH still looks like mainnet gas.

Frequently asked questions
What is the best way to swap USDC from Polygon to ETH on BNB Chain?
Sell 0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359. Buy 0x2170Ed0880ac9A755fd29B2688956BD959F933F8. XAUConnect compares live routes and lets your own wallet sign.
Is Binance-Peg ETH the same as WETH?
No. Ethereum WETH is 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 on chain id 1. This route buys 0x2170Ed0880ac9A755fd29B2688956BD959F933F8 on chain id 56. ETH is not WETH, and the peg is neither of them. BscScan is the explorer for the credit. Etherscan will not list this debit. Do not treat the peg as mainnet gas.
Will this fund gas on BNB Chain?
No. The peg cannot pay fees. BNB does, and this quote does not buy the native label. Keep BNB in the destination wallet or the new token cannot move. Blocks near 3 seconds describe BNB Chain only, not the bridge finish. Fund BNB before you need to move the peg.
What if my USDC is the bridged Polygon kind?
Then stop. USDC.e is 0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174. This page spends 0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359. Polygonscan will show an approval of the wrong contract if you force the bridged token. POL is still required on chain id 137. Switch to native Circle USDC before you approve, or the bridged balance stays put.
