RollCall: Rollup Governance Libraries
RollCall is a set of cross chain governance solutions
- L2Voter: Voting on mainnet governance proposals on a rollup.
- Executor: Manage mainnet treasury from a governance on a rollup.
Quickstart
Install foundry https://github.com/gakonst/foundry#installation
Run tests
forge test --vvv
L2Voter
Voting on Ethereum mainnet (Layer 1) governance proposals on an Optimistic Rollups (Layer 2). We move only the voting to Layer 2.
To do so, Layer 1 governance's implementation provides a set of weight mappings (mapping(address => uint256)) which are used to compute a voters weight. When a proposal is created, the storage root of the block is bridged to Layer 2 and voters can submit votes on Layer 2 using storage proofs.
Goals
- Reduce the overhead for participating in governance by reducing voting gas costs
- Enable onchain governance for tokens which do not already support the snapshot functionality.
- Provide a modular framework for governance voting, where vote weights can be pulled from one or more sources and is not limited to token voting exclusively.

Generating Storage Proofs
Install Golang.
Run the generate script with the desired contract, voter address, and mapping storage slot
go run src/test/data/generate.go -contract 0x7ae1d57b58fa6411f32948314badd83583ee0e8c -voter 0xba740c9035fF3c24A69e0df231149c9cd12BAe07 -slot 0
Executor
Manage Ethereum mainnet (Layer 1) treasury from a governance on an Optimistic Rollups (Layer 2). We move the DAO, minus the treasury, to Layer 2.
Goals
- Provide path for incremental migration of DAO Governance from Layer 1 to Layer 2.
