What is QuantArk

QuantArk is a Solana launchpad. Anyone can launch a coin on a bonding curve, and anyone can trade it. Three things set it apart from other launchpads.

	Typical launchpad	QuantArk
Quote token	SOL	Q2, backed by GOOGLx and NVDAx
Treasury key	Ed25519 wallet or multisig	LM-OTS one-time hash signatures
Holder protection on Q-day	None	Lifeboat key plus on-chain snapshots
Launch data	Price and holders	Bundle share, dev holdings, flow, Lifeboat coverage

Why a stock basket

A memecoin quoted in SOL holds SOL in its curve. A coin quoted in Q2 holds tokenized shares of Alphabet and NVIDIA, two of the companies building quantum computers. If quantum computing arrives faster than expected, the basket is the part of the market built to benefit. If it never arrives, the curve still holds stocks rather than nothing.

Q2 is minted only by depositing the stocks and burned back into them on request, so every Q2 in circulation has its stocks sitting in the basket vault. See Q2, the stock basket.

Why Q-day matters

Q-day is the day a quantum computer can derive an Ed25519 private key from its public key. Every Solana wallet is an Ed25519 key, and every public key is visible on-chain. From that day an attacker could sign as any wallet.

QuantArk prepares for that in two ways.

Fees land in a vault that only opens with a hash-based LM-OTS signature, which a quantum computer cannot forge. See Hash-signed treasury.
Holders can register a Lifeboat key now, before anything breaks, so ownership can be proven later with a key that was never Ed25519. See Lifeboat and snapshots.

A public on-chain canary watches for the break. When it trips, QuantArk freezes every action that trusts Ed25519. See Q-day and the canary.

What is honest to say today

Some parts are not quantum-safe yet: the bonding curve program belongs to Meteora and is upgraded with an Ed25519 key, and the Lifeboat recovery claim is not built. The Security model page lists exactly which parts are covered.
