Morylen Airdrop Kit

A standalone toolkit that runs a token airdrop from start to finish on any EVM chain — no database and no cloud. It is the exact code behind the Musicoin → MORY distribution, released so anyone can audit it, reproduce the Merkle root, and run their own campaign. MIT licensed.

What's inside

Smart contracts

A gas-efficient MerkleDistributor (claim by proof, sweep unclaimed after the deadline, reentrancy-guarded), an EscrowClaimDistributor for a gasless, front-run-safe email claim to a new wallet (for keyless custodial holders), plus a fixed-supply ERC20 template. Hardhat project with cross-checked test vectors.

Core engine

Ingest → allocate → build Merkle tree → estimate cost → preflight gate → nonce-safe, resumable bulk send (skips already-claimed, checkpoints progress, survives interruptions).

CLI

Keyless by default — the kit prints calldata and you sign in Ledger or Safe; a hot-key is opt-in (encrypted keystore) only for high-volume pushes.

Operator console (local web)

A localhost dashboard to deploy, fund, and bulk-send, plus an email mapping workspace: export a template, import contacts, see coverage, and notify recipients with delivery/bounce handling.

The Musicoin → MORY campaign data

The kit ships with the real, verifiable distribution. Every figure below is reproducible from the included files — rebuild the tree with scripts/verify-all.ts and you get the same Merkle root, byte for byte.

Run it

unzip airdrop-kit-1.0.2.zip && cd airdrop-kit
npm install
npm test                 # full test suite
npm start                # local operator console (http://localhost:4321)
npm run airdrop -- --help   # the CLI

# reproduce the Merkle root from the bundled data:
node --import tsx scripts/verify-all.ts examples/morylen-campaign

Public data only. The bundle contains wallet addresses and on-chain amounts — no emails or personal data. The Merkle root is the same value committed on-chain.
