claiming-app-data

The code in this repository was originally copied from the gnosis/safe-claiming-app-data repo and then modified to suit the Shutter DAO requirements.

A vesting data converter and proof generator.

Prerequisites

Place csv files with vesting data under vestings/assets/{chain_id}/*.csv.

Vesting CSVs

Vesting CSV files contains the following fields

owner: Must be an Ethereum address
amount: Token amount to be allocated
duration: Vesting duration in months
startDate: Vesting start date (ISO 8601 Format YYYY-MM-DD)
initialUnlock: Initial unlocked token share in decimal fraction (0...1)
requiresSPT: TRUE or FALSE if it is required to exchange SPT tokens upon claiming tokens (only valid for SPT holders)

Allocation file structure

Vesting file

Contains all defined allocations for a specific address with proofs.

[
    {
        "tag": "[user | spt_conversion]",
        "account": "checksummed address",
        "chainId": chain id,
        "vestingId": "vesting hash",
        "durationWeeks": integer,
        "startDate": timestamp,
        "amount": "amount in wei",
        "curve": integer,
        "proof": [
        ]
    },
    ...
 ]

Setting up locally

Create a Python virtual environment

python -m venv venv

Activate a virtual environment

source venv/bin/activate

Install dependencies

pip install -r requirements.txt
pip install pre-commit
pre-commit install -f

Generating output files

The exporter script can parse vesting CSV files, generate proofs, and export data for claiming. The steps mentioned earlier can be performed at once or separately.

Example:

cd vestings
python exporter.py --chain-id 1 --output-directory ../data/allocations

Exporter will place generated files under {output_directory}/{chain_id}

Output files

For each address, an allocation file is created {address}.json. These files contain the Merkle proof and all relevant data to redeem the tokens into the vesting pool contract later.

Additionally, the file root.txt containing the Merkle root is created. Take this value and configure the respective parameter upon DAO deployment.

All files are located under {output_directory}/{chain_id}.
