# Merkle Airdrop

## What is this?

Complete airdrop solution for [Tezos](https://tezos.com/) tokens.

The chosen solution uses merkle trees.

The advantages are of 2 kinds:

- It is cheap because fees will be paid by the claimers.

- It brings engagement, requiring some action from the claimers.

Status is experimental / side-project.

If you are looking for real airdrops, take a look at [organicgrowth.wtf](https://www.organicgrowth.wtf) 

(on etherlink)

## How it works?

An airdrop project consists in off-chain and on-chain data:

- [on-chain](./contracts), there is a smart-contract that holds projects information, e.g: the token contract address,

the hex of a merkle root of beneficiaries (address, amount), and the registry of already claimed beneficiaries entries.

- [off-chain](./app), the merkle tree must be stored to be able to generate the merkle proofs required to claim.

An off-chain app also is helping on the merkle tree generation and validation before deploying the airdrop contract.

## Prerequisites

- [taqueria](https://taqueria.io/docs/getting-started/installation) is used for the contracts stack

- PHP8 is used for the dApp

- docker for infra (MySQL, adminer, flextesa..)

## Why PHP?

- it is still the king of cheap hosting.

- it has great retro-compatibilty

- it is [evolving](https://php.watch), there is a [PHP fundation](https://thephp.foundation/) now, and everything is [discussed openly](https://php.watch/rfcs).

- it still runs an important part of the web, and we want to make decentralized apps, so why not using a popular language for this.

## Dev

1. Install dependencies: `make install`

2. Launch infra: `make up` (Stop it: `make down`)

4. Compile contracts: `make compile`

5. Deploy contracts: `make deploy`

6. Start app: `make start`

Then, you'll have :

- adminer available at 

- local sandbox at 

- tzkt api at 

## Dapp

Use [flextesa](https://gitlab.com/tezos/flextesa)'s bob or alice for dev purpose, you can also add

choosen deterministic keys in the [testdata script](./infra/testdata.ts).

Otherwise, you can add your address in same script.

The Dapp will check for the address existence in the [Identifier](./app/src/Identifier/TezosIdentifier.php).
