Fee Structure
To ensure seamless cross-chain transfers and a stable user experience, our fee model consists of two key components. The structure is designed to be transparent, predictable, and competitive across different blockchain networks.
Our fee system includes:
Bridge Fee – A percentage-based service charge applied to the amount being transferred.
Destination Transaction Cost – A fixed fee used to cover on-chain transaction costs on the destination network.
This two-part fee model enables fast, secure bridging while ensuring fair compensation for protocol participants such as market makers.
Bridge Fee
The Bridge Fee is a service fee calculated as a percentage of the asset amount being transferred. It is charged to cover the operating costs of the protocol and provide incentives to liquidity providers who facilitate cross-chain transfers.

This fixed-rate model allows users to understand and estimate their costs before initiating a transfer.
Destination Transaction Cost
After initiating a transfer, a transaction must occur on the destination chain to complete the process – for example, to claim or mint the bridged asset. This Destination Transaction Cost is prepaid by the user and covers the required network fees (gas) on the destination chain.

The actual cost may vary by network conditions, but our mechanism ensures price efficiency through smart adjustments.
Dynamic Adjustment Policy
Gas costs are variable between different blockchains and over time. To maintain cost-effectiveness across Layer 1 and Layer 2 networks, our fee system includes dynamic adjustment of the Destination Transaction Cost, based on:
The current gas price (Gwei) of the destination network
Historical average fees
Fee efficiency targets compared to market norms
These adjustments are infrequent and aim to keep user costs below or at the market average, promoting both fairness and sustainability.
Examples
Our fee mechanism operates on an "External Deduction" principle — users specify the exact amount they wish to receive on the destination chain. The system then calculates the required source chain amount inclusive of all associated fees. Assuming a bridge fee rate of 0.01%, the fee calculation formula is:
Total Fee = (0.01% × Bridged Amount) + Destination Chain Transaction Cost
You want to receive 1 ETH
Bridge Fee: 0.0002ETH (0.02%)
Destination Transaction Cost: 0.00005 ETH
You pay: 1 + 0.0002 + 0.00005 = 1.00025 ETH
Fee Transparency and Updates
Users can always preview the exact fees before confirming any transfer. We are committed to fee transparency and provide timely updates on any changes.
All fees are displayed within the app prior to confirmation
Fee adjustments (if any) are announced via Discord and Twitter
No hidden or backend charges apply
