Overview

The Formfunction Gumdrop is a port of the Metaplex Gumdrop Program which uses merkle trees to support efficient airdrops of tokens and NFTs. The Formfunction Gumdrop is designed specifically to facilitate airdropping participation NFTs (pNFTs) from creators to auction participants.

Repo Structure

This repo contains the Solana program source code and the source code for a TypeScript SDK, in addition to some client-side program tests written in TypeScript.

Initial Environment Setup

Complete the following to setup your environment:

1. Install Node.js (and nvm if you want).
2. Follow the Anchor setup instructions. After this you should have Rust, Solana, Yarn and Anchor installed on your system.

Getting Started

Once you have your environment setup you can run the following:

# Install npm dependencies
$ yarn

# Build the program and SDK
$ yarn build

# Run sdk TS only unit tests
$ yarn test-sdk

# Run tests using Anchor (spins up local validator and deploys program)
# Note that you will need to give permission to the test.sh script the first
# time you run the tests (run 'chmod +x ./scripts/test.sh').
$ yarn test

# Run a command like this to test a single file
$ yarn test claimEditionInvalidCases.test

# Run tests in debug mode to show more error output
$ yarn test-debug

The following commands are also available:

# Run prettier checks
$ yarn prettier

# Run eslint checks
$ yarn eslint

# Compile TypeScript code
$ yarn tsc

# Build the program
$ yarn build-program

# Run setup step to copy generated program IDL and types to src/ folder
$ yarn setup

# Build the TS SDK
$ yarn build-sdk

Releases

Releases are based on git tags. There is a GitHub Action which is responsible for running releases.

The Solana program and TS SDK are versioned separately.

Solana Program

For the Solana program we build a binary using Anchor. To publish a new binary:

1. Increment the version in the program Cargo.toml file.
2. Push a commit to the main branch in GitHub.

Note that if the Anchor version is upgraded you should update the anchor version in the GitHub action as well.

Devnet Deployment

Run the following to deploy or upgrade the program on devnet or testnet:

# Set your CLI to the appropriate cluster.
$ solana config set -u devnet|testnet

# Give the script executable permissions (needed once on first use only)
$ chmod +x ./scripts/deploy-program.sh

# Note: If you are deploying for the first time, you need to specify the deploy
# command program-id argument to point to the program keypair.

# Get the deployer account address.
$ solana-keygen pubkey keys/devnet/deployer-keypair.json

# Ensure you have enough SOL. Repeat the following for the above address
# until you have ~10 SOL or more.
$ solana airdrop 1 G1K5YZmhg1LqaYUC9VXWK7YLCdwqJcVPLpgBt5tmUWVf

# Test, build and deploy the program. Pass argument for network.
$ yarn deploy-program devnet|testnet

After the initial deploy you will have to create the Gumdrop Config account. See the below section for the details.

To deploy the program from scratch to a new program address, do the following:

• Update the DEPLOY_PROGRAM_ID in deploy-program.sh.
• Add the new program address in Anchor.toml and all of the Anchor configs in scripts/anchor-configs.
• Add the new program and config keypairs for devnet/testnet in keys/.
• Update programIds with the new addresses.
• Update the address in keys/README.
• Run the above deploy steps.
• If you updated the gumdrop config authority address, update the appropriate environment variable in the Formfunction server deployments (local and in GitHub Secrets).

Mainnet Deployment

Gumdrop is deployed on Solana mainnet at gum8aDxTHP5HSXxQzVHDdSQJGUQFLreGDX2cUa133tk.

Gumdrop Config

The program requires a one-time setup of the Gumdrop Config account. You can create this by running the following:

# Set the config authority for devnet or testnet
$ yarn set-config devnet|testnet

# Set the config authority for mainnet (this will use the Anchor-prod.toml configuration)
# For the production config account, a new keypair will need to be created and funded with SOL
# prior to running the script.
$ yarn set-config mainnet

A similar script exists to update the config authority. The update script expects a keypair for the new update authority to be provided in the relevant folder: keys/testnet|devnet/update-config-authority-keypair.json.

# Update the config authority for devnet or testnet
$ yarn update-config devnet|testnet

# Update the config authority for mainnet (this will use the Anchor-prod.toml configuration)
# For the production config account, a new keypair will need to be created and funded with SOL
# prior to running the script.
$ yarn update-config mainnet

NOTE: If you update the config authority be sure to update the new gumdropConfigAuthority address in programIds.ts.

TypeScript SDK

Follow the following steps to publish a new version of the TypeScript SDK:

1. Run yarn version and enter a new appropriate semver version for the npm package. That will create a new tag and commit.
2. Run git push origin NEW_TAG.
3. git push the new commit as well.

This will push the new release tag to GitHub and trigger the release pipeline, after which clients can install the latest SDK with yarn add @formfunction-hq/formfunction-gumdrop@latest.
