| title: Deployed MACI Smart Contracts | ||
| description: Deployed MACI Smart Contracts | ||
| sidebar_label: Deployed MACI Smart Contracts | ||
| sidebar_position: 10 | ||

|
|
||
| There are a number of MACI's smart contracts which can be re-used by different deployments. These are the following: | ||
|
|
||
| - [VkRegistry](https://github.com/privacy-scaling-explorations/maci/blob/dev/contracts/contracts/VkRegistry.sol) | ||
| - [PoseidonHashers](https://github.com/privacy-scaling-explorations/maci/blob/dev/contracts/contracts/crypto/Hasher.sol) | ||
|
|
||
| VkRegistries can be re-used by different protocols to share the same set of verifying keys. Please be advised that you should be verifying that those verifying keys are the ones that have undergone a trusted setup ceremony. | ||
|
|
||
| In order to verify you will need the following: | ||
|
|
||
| - configure the cli (`cd cli && cp .env.example .env` and set the correct env vars) | ||
| - download the keys (`pnpm download-zkeys:ceremony` from the monorepo root) | ||
| - run checkVerifyingKeys with the cli (see below) | ||
|
|
||
| ```bash | ||
| cd cli && node build/ts/index.js checkVerifyingKeys -q false -vk 0x74569d524a193daC0D3Df17B9E207C916174745b -s 6 -i 2 -m 9 -v 3 -b 2 -p ./zkeys/ProcessMessages_6-9-2-3/processMessages_6-9-2-3.zkey -t ./zkeys/TallyVotes_6-2-3/tallyVotes_6-2-3.zkey | ||
| ``` | ||
|
|
||
| :::info | ||
| You should change the -vk parameter to the VkRegistry address for the chain you are deploying to. Also you might need to modify the parameters based on the circuit configuration. Please refer to the [circuits page](/docs/developers-references/zk-snark-circuits/setup) for more information. Also you can add `-uq false` if you want to check non quadratic voting keys. | ||
