Mysten Reports Sui's First Native Quantum-Safe Devnet Transaction
Mysten Labs said Sui completed its first native quantum-safe transaction on devnet after adding ML-DSA-65 account signatures. Native mainnet support is targeted for Q1 2027, with audits and testnet feedback still part of the plan. Other coverage framed the update as a development-network step for post-quantum accounts and said the implementation is in version 1.82.0.
What this rests on
What it means
Each sentence links inside to the piece that supports it.
Builders working on Sui devnet are the first group to notice this directly, because the network now has a native quantum-safe transaction path available for testing there. That makes the development environment the place where post-quantum account behavior can be exercised today, while mainnet support remains set for later.
In practice, the change is that devnet now includes ML-DSA-65 account signatures, which lets builders test secure transaction workflows on the network’s development environment. What stays unchanged is that native mainnet support is still only targeted for Q1 2027, with audits and testnet feedback still part of the plan.
Market reaction
The move was larger before the first headline than after. That is an observation, not an explanation: the market also moves on things nobody publishes.
How the story was built
Every piece in order, with the time its news medium declares — if it is not believable we use ours and say so — and what it added to what was already known at that point. Arriving first is not the same as adding something.
