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

Claim by claim, with its source
✓
Mysten Labs said Sui completed its first native quantum-safe transaction on devnet after the network’s devnet implementation added ML-DSA-65 account signatures.
✓
Mysten Labs said native mainnet support is targeted for Q1 2027.
✓
The update was framed as a quantum-safe transaction milestone for Sui and as part of a shift toward stronger blockchain security.
✓
Sui’s update was described as a development-network step for post-quantum accounts, with comments from Mysten Labs co-founder Kostas Chalkias attached to the announcement.
✓
The devnet upgrade was described as version 1.82.0 and as using NIST-approved ML-DSA-65 algorithms so builders can test secure transaction workflows.

What it means

Who it affects, what changes and what is still unconfirmed

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.

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.
