## Eclair Merges Fee Fixes
Eclair Lightning implementation merged two fixes to prevent nodes from paying excessive Bitcoin mining fees during collaborative channel funding and transaction construction.

> A malicious peer could make us pay mining fees at an arbitrary feerate, while contributing nothing
## First Fix Limits Fee Rate
The first change, merged Oct. 2, 2026, limits the fee rate a peer can impose during a replace-by-fee transaction involving a dual-funded channel opening or a splice.
## Second Fix Checks Fee Accuracy
The second fix, merged Oct. 5, 2026, addresses Eclair-signer mode by calculating actual fees and rejecting invalid change-output positions.

> We now check that the rebuilt contributions pay exactly the fee we verified on the funded transaction
## Key takeaway

Eclair merged two fixes to stop nodes from paying excessive Bitcoin mining fees during collaborative channel funding and transaction construction.
