Bridge Fees vs. Slippage

Cross-chain routes can combine several costs. Looking at only one fee line can hide the difference between protocol charges, network costs and price movement during an embedded swap.

Key idea

Compare input with final received amount first, then use the fee breakdown to explain the difference.

01

Fees are explicit charges

Network and protocol fees are identifiable costs in the route. Their structure depends on the chains and bridge mechanism involved.

02

Slippage comes from execution

If the route includes a swap, available liquidity can make the execution price differ from the quoted market price. That difference is separate from a protocol fee.

03

Compare the final outcome

The cleanest comparison is input versus expected destination amount for the same route and timing. Then inspect the breakdown to understand why two quotes differ.

Cross-network asset movement

A bridge coordinates asset or message state between independent networks.

  1. 01

    Source

    Lock, burn or deliver an asset into a bridge mechanism

  2. 02

    Verification

    A bridge or message layer verifies required conditions

  3. 03

    Destination

    Release, mint or deliver the destination-side asset

Important: Different bridges have different trust, liquidity and finality assumptions.
