Distribution Script

This command-line application, written in Rust, verifies signed Gnosis validator data and checks if the signer an active HOPR node runner.

This script uses alloy-rs for Ethereum primitives and graphql_client to query subgraphs. When querying subgraphs, it first attempts to query the production subgraph endpoint but falls back to the development endpoint in the Subgraph Studio.

Development Installation

1. Install Rust using the official guide.
2. Build:

$ cargo build

3. Create a .env file according to the .env.example and fill it in with API keys.
4. Load environmental variables:

$ source .env

5. Run to see the --help message:

$ cargo run -- -h

Usage

1. Production build:

$ cargo build --release

$ ./target/release/distribution_script --help
Usage: distribution_script [OPTIONS] --deposit-data-dir <DEPOSIT_DATA_DIR> --claim-history-path <CLAIM_HISTORY_PATH>

Options:
    -i, --input-signed-data-dir <INPUT_SIGNED_DATA_DIR>
            Directory to where all the input signed deposit data files are stored
    -o, --output-deposit-data-dir <OUTPUT_DEPOSIT_DATA_DIR>
            Directory to where the final output deposit data file is stored
    -t, --hopr-amount <HOPR_AMOUNT>
            HOPR amount in ether, e.g., 10000000 [default: 10000000]
    -m, --min-nodes <MIN_NODES>
            Minimum number of nodes in a Safe [default: 1]
    -b, --block-number <BLOCK_NUMBER>
            Snapshot block number for the subgraph query [default: 34310645]
    -h, --help
            Print help
    -V, --version
            Print version

Example

There are two identical signed deposit datas under the ./test/input folder. Check if they are eligible if the minimum requirement is to have at least 20 HOPR tokens in a Safe and 1 running HOPR node:

$ cargo run -- --input-signed-data-dir ./test/input -o ./test --hopr-amount 20 --min-nodes 1 --claim-history-path ./test/claim_history.csv > ./test/result.log

The command above should return an empty array as a result.

$ cargo run -- --input-signed-data-dir ./test/input -o ./test --hopr-amount 0 --min-nodes 0 --claim-history-path ./test/claim_history.csv > ./test/result.log
