Do wallets with cross chain swaps optimize for gas fees?
One thing that still confuses me in DeFi is how gas fees work when you’re trading across multiple chains. On Ethereum, I’ve had trades where the fees were almost as much as the actual swap. Then on chains like Polygon or BNB it’s pennies in comparison.
Some wallets have “cross-chain swaps” directly inside the wallet. Instead of me bridging manually and then swapping on a DEX, the wallet just handles it in the background. Sounds convenient, but do these wallets actually optimize for fees behind the scenes, or are they just routing through whatever bridge/DEX combo is available at the moment?
Wallets like Bitlock wallet lets you pick tokens across ETH, BNB, Polygon, Solana, etc. and it just executes. But do they automatically find the lowest gas + swap fees? Or am I better off watching gas trackers and timing my own swaps manually if I want the absolute best rates?
Most cross-chain bridges plan for the worst case on the second chain and either overcharge or else slow your transaction until rates are affordable. Cross-chain wallets are just another layer wrapping those services (and possibly adding their own additional fee).
