Tokenized stocks are moving onchain. Their authorization needs to prepare for a post-quantum future.
Introducing Quantum Stocks. Now live on mainnet.
CA : 0x839beb7d5032b4dd2ebdc7b17c1286dcd97ad144
Our post-quantum design brings together:
• ML-DSA-44 module-lattice signatures under NIST FIPS 204
• Dual-layer authorization
• SHA-256 intent binding across chain, program, owner, action, asset, amount and receiver
• Nonces and expiry to prevent replay
• Staged buffers for larger signature payloads
The goal: bind authorization to exactly what you approve, using signatures designed to withstand quantum attacks.
Tokenized stocks. Dividend claims. Collateralized borrowing.
Building First post-quantum financial infrastructure for Robinhood Chain and Solana.

Wall Street is moving onchain. Is its security ready for Quantum-Day?
CA: 0x839beb7d5032b4dd2ebdc7b17c1286dcd97ad144
Tokenized stocks depend on cryptographic signatures to authorize transfers. Q-Day is the point when sufficiently powerful quantum computers could break today’s widely used public-key cryptography.
That’s why we’re building toward post-quantum authorization at Quantum Stocks.
• ML-DSA-44 signatures • Authorization bound to the exact transaction intent • A focus on tokenized stocks, dividend claims and collateralized borrowing
Watch the explainer below to understand why this matters for onchain finance.
BlackRock CEO Larry Fink says this is only the beginning as the tokenization of everything is underway.
Money, property, and even personal identity will soon exist in digital form.
He calls it a major opportunity for BlackRock, saying the plan is to move beyond traditional financial assets by digitally re-potting them into a new system.
