Bridge Comparator

Bridges charge a percentage, gas, or both, and the cheaper one flips with transfer size. Compare two quotes properly instead of trusting the louder UI.

How it works

total = amount × fee % + fixed gas

Worked example

Moving $2,000: 0.05% + $6 gas costs $7, while 0.3% + $2 costs $8. At $500 the second bridge wins ($3.50 vs $6.25). Size decides.

FAQ

What matters beyond cost?

Security model and speed. Bridges are crypto's most-hacked category; a 0.1% saving through an unaudited bridge is a bad expected value.

Why did I receive less than quoted?

Destination gas, slippage on pool-based bridges, or a relayer fee taken in-kind. Compare received amounts, not advertised fees.
