Deploy a Frontend

MACI Platform is a complete frontend solution for running voting or funding rounds using MACI. This guide explains how to deploy MACI Platform.

Setup​

Start by cloning the MACI Platform repo:

git clone https://github.com/privacy-scaling-explorations/maci-platform

Head to the folder and install the dependencies:

cd maci-platform && \
pnpm install

Configuration​

Copy the example variables and update them accord to your needs:

cp packages/interface/.env.example packages/interface/.env

At the very minimum make sure to configure:

  • BLOB_READ_WRITE_TOKEN. Storage for applications metadata.
  • NEXT_PUBLIC_ALCHEMY_ID. Optional but highly recommended for RPC calls.
  • NEXT_PUBLIC_REGISTRATION_END_DATE. Determine when users can register application.
  • NEXT_PUBLIC_ADMIN_ADDRESS. Address that will approve applications and voters
  • NEXT_PUBLIC_APPROVAL_SCHEMA. Schema for applications and voters.
  • NEXT_PUBLIC_METADATA_SCHEMA. Schema for storing metadata refs.
  • NEXT_PUBLIC_MACI_ADDRESS. The MACI contract address deployed on the Getting Started Guide.
  • NEXT_PUBLIC_MACI_START_BLOCK. Block when was deployed the MACI contract.
  • NEXT_PUBLIC_MACI_SUBGRAPH_URL. URL of the Subgraph deployed on the Subgraph Deployment Guide.
important

Make sure that the EAS schemas exist in the network that you are using.

Build the repo with the following command.

pnpm build

In order to run the interface locally can run:

pnpm dev:interface

Deploy Poll​

Once you have configured the repo with the subgraph and MACI contract you only need to deploy a poll on MACI.

pnpm deploy-poll:NETWORK

Deploy Frontend​

The easiest way to deploy MACI Platform is using vercel.

  1. Import the repo you created/forked
  2. Open the Environment Variables panel
  3. Select the first field and paste your variables from your text editor.
  4. Deploy!

Results​

Once the voting time has ended, as a coordinator, you need to merge the signups and generate the proofs. This is done on the MACI repo.

This is going to generate a tally.json file, then you need to rename it as tally-{pollId}.json or tally-{roundId}.json, upload it and add it as an environment variable NEXT_PUBLIC_TALLY_URL. The frontend will read this variable and will display the results.

important

We recommend you use vercel storage to upload the tally-{pollid}.json file.

Credits​

The interface originally started as a fork of easy-rpgf, but has since taken a completely different direction. As a result, we decided to detach the fork to clarify the project's new focus, which now extends beyond RPGF to include other types of voting and funding.

We are very thankful to the developers and all contributors of the easy-rpgf project, and we hope to continue collaborating and wish to see their project succeed and help more communities/projects get funded.
