# Protocol Fee Expansion: Vote 2
AI summary
This proposal aims to expand the Uniswap protocol fee mechanism to five additional blockchain networks: Soneium, XLayer, Celo, Worldchain, and Zora. If passed, it will enable the collection of fees on Uniswap V2 and V3 transactions on these chains. The proposal involves executing ten cross-chain transactions to set the owner of the V3 Factory to the V3OpenFeeAdapter and direct V2 protocol fees to the TokenJar on each of these networks.
If this proposal passes, Uniswap will begin collecting protocol fees on transactions occurring on Soneium, XLayer, Celo, Worldchain, and Zora, potentially increasing revenue for the Uniswap DAO treasury. Users of Uniswap on these chains might see a slight increase in transaction costs due to these fees. The proposal does not specify the exact fee percentage or the expected revenue.

Protocol Fee Expansion: Vote 2
Proposal Spec
If this proposal passes, it will execute ten transactions:
/// Enable fees on Soneium, XLayer, Celo, Woldchain, and Zora. For each chain:
/// Set the owner of the V3 Factory to the V3OpenFeeAdapter
V3_FACTORY.setOwner(address(v3OpenFeeAdapter));
/// Set the recipient of V2 protocol fees to the TokenJar
V2_FACTORY.setFeeTo(address(tokenJar));
Because these transactions are crosschain, governance front ends may not decode them correctly. We recommend reviewing the [Seatbelt simulation report](https://github.com/uniswapfoundation/go…
