Scores
Each criterion carries equal weight. The overall score is the average of these 5 scores — (9.0 + 5.0 + 4.0 + 7.0 + 2.0) ÷ 5 = 5.4.
Pros
- Flat fee published per chain, from 0.001 ETH to 15 CRO, across seventeen networks
- Variable component stated precisely as 4 bps of the input token
- Explicitly warns that fees can change and must be queried from the contract rather than hardcoded
- Seventeen chains enumerated in the fee table
Cons
- Trust model is described as a self-organised liquidity network with no validator or verification mechanism explained
- Business Source License 1.1 whose change date of 31 December 2025 has already passed
- No audits page could be reached and no auditing firm is named
A fee table that names every chain
deBridge publishes a flat fee for each supported network in that chain's native gas token — 0.001 ETH on Ethereum and the major L2s, 0.05 AVAX, 0.005 BNB, 0.5 MATIC, 0.015 SOL, 15 CRO, 4 TRX and so on — alongside a 4 basis point charge on the input token.
It also does something almost nobody else does: it warns that protocol fees can change and that integrations must query them dynamically from the contract rather than hardcoding them. Telling developers your published numbers are not stable is a form of honesty worth crediting.
The security description is thin
The architecture is described as a self-organised liquidity network executing trades asynchronously with zero total value locked. What that means for who can move funds, and under what assumption, is not set out.
A lapsed licence and no audits
The BUSL change date of 31 December 2025 passed before we checked, and no audit page could be reached.
