1

The "Stuck Gas" Problem

If you bridge USDT to Polygon but have no MATIC for gas, you are stuck. Always use a bridge that has a "Gas Refuel" option (like Jumper/Bungee).
2

The CEX Workaround

Easiest Method: Send Crypto A to Binance. Withdraw Crypto A to Target Chain. Binance handles the bridging for you.
3

Official Bridges

Arbitrum Bridge, Optimism Gateway. These are slow (7 days withdrawal) but safest. Third-party bridges (Orbiter) are faster but riskier.
4

Wrapped Tokens

Know what you are getting. "USDC.e" is bridged USDC. "Native USDC" is issued by Circle. Some Dapps accept one but not the other.

Common Questions

Q: My funds are stuck in the bridge?

Bridges can take 10-30 mins. Check the block explorer (LayerZero Scan). If it has been hours, check their Discord.
