What is PostQ?

PostQ is an ERC-20 token on Ethereum where every token must be earned through a valid post-quantum cryptographic signature. No whitelist. No presale. No allocation. You prove you can produce a hash-based PQ signature → you mint.

• Total Supply: 7,500,000 POSTQ
• Public Mint: 5,000,000 (10,000 slots × 500 POSTQ)
• LP Reserve: 2,500,000
• Team Allocation: 0
• Mint Price: 0.0025 ETH per slot

Quick Start

Check mint progress

npx postq-miner status

Mine (mint 500 POSTQ)

npx postq-miner mine

You'll be prompted for your private key (masked input). Or set it as an env var:

PRIVATE_KEY=0x... npx postq-miner mine

Requirements

• Node.js 18+
• ETH wallet with at least 0.003 ETH (0.0025 mint + gas)
• That's it. No other setup needed.

Install (optional)

You can run without installing via npx, or install globally:

npm install -g postq-miner
postq-miner status
postq-miner mine

1. Keygen — Generates a one-time post-quantum keypair (hash-based, SPHINCS-style)
2. PQ Sign — Signs a challenge message using the PQ private key
3. Attestation — Backend verifies your PQ signature is valid, then signs an ECDSA attestation
4. Mint TX — CLI submits the attestation to the smart contract → 500 POSTQ minted to your wallet

Each PQ key can only be used once. After minting, the public key hash is permanently recorded on-chain.

PostQ Token	0xa81Ae8c88DBe2A48304204eA65c56017642D9Db7

Both contracts are verified on Etherscan. No admin keys, no proxy, no pause function, fully immutable.

Security

• Your private key is never sent to the backend. It stays local.
• The backend only receives the PQ keypair (generated fresh each time) and your recipient address.
• All PQ signatures are independently verifiable.
• The smart contract is immutable — no owner, no admin, no upgrade mechanism.
