zkSync

ZKsync posted a teaser on X promising a Prividium announcement "Tomorrow," alongside a short video preview. No further details have been disclosed, but the teaser signals a new development coming to Prividium, ZKsync's DLT platform for financial institutions.

Matter Labs, the firm behind ZKsync, submitted a public comment letter to the SEC on the agency's Tokenized Securities Venue (TSV) exemptive order (File No. 4-927). Matter Labs said it supports the order and asked the Commission to confirm that validity proofs verified on a public, permissionless ledger meet the specified requirements of the exemption.

The TSV order, issued by the SEC, grants temporary conditional relief from the definition of "exchange" to venues trading tokenized NMS stock using permissioned automated market maker liquidity pools. ZKsync highlighted the submission on its X account as part of Matter Labs' ongoing engagement with US securities regulators on tokenized securities infrastructure.

DTCC launched its Tokenization Service, with 20 participants signed up for access, and ZKsync is among the firms collaborating, providing privacy features through Prividium. Alongside the launch, Prividium completed its SOC 2 Type 2 examination, demonstrating the controls required by regulated institutions — a compliance milestone ZKsync has now highlighted as "proven, not assumed." ZKsync CEO Alex Gluchowski called the DTCC partnership "a huge milestone," saying Prividium brings privacy to the network.

• The service helps institutions keep sensitive financial activity private while retaining control over transactions and oversight of daily operations.
• Prividium lets institutions run digital asset services under their own rules, connected to systems they already use.
• DTCC provides custody and asset servicing for more than $114 trillion in securities.

ZKsync unveiled Prividium Commander, a digital-assets control plane for institutions, announced by Matter Labs CEO Alex Gluchowski during his Money20/20 keynote — a video of which ZKsync published. The product brings permissioning, approvals and audit trails — along with operating, security and audit tooling — into one offering that runs under an institution's own rules and connects to the systems they already use.

• Commander is positioned to move institutions from pilots to production revenue by cutting the operational complexity between a successful pilot and a production digital-asset service.
• It is the latest addition to Prividium, ZKsync's DLT platform for financial institutions, which has a dedicated website showcasing the full platform of products.

In its October monthly recap, ZKsync highlighted several ecosystem developments. ADI Chain and the Government of Gibraltar signed an MoU to establish a multi-currency stablecoin consortium on ADI Chain, and Memento launched Confido, bringing private onchain transactions to Ethereum.

The recap also noted that GRVT, ZKsync's institutional derivatives venue, ranks among the top 5 perp DEXs with $483M in open interest — alongside the launches of Prividium Commander and the DTCC Tokenization Service.

ZKsync congratulated its partner GRVT on a collaboration with Mirae Asset Securities in which GRVT subscribed to an issuance of tokenised funding notes arranged by Mirae Asset Securities (HK) Limited under its affiliate's structured notes programme. ZKsync said the transaction is built on Prividium, its DLT platform for financial institutions.

• GRVT plans to use the exposure in connection with its Grvt Earn product, subject to applicable requirements.
• The firms intend to explore further tokenised products — Treasuries, corporate bonds and ETFs — on a non-committed basis, pending regulatory approvals.
• Backer Mirae Asset Financial Group oversees more than US$1 trillion in client assets; the funding note transaction marks the firms' first collaboration.

ZKsync has introduced Airbender Prime, which it describes as the first Ethereum prover to demonstrate real-time proof generation on a single GPU — and now promotes it as "Ethereum's fastest prover." In an evaluation, one NVIDIA RTX PRO 6000 Blackwell proved 99% of 7,200 consecutive Ethereum mainnet blocks in under 10 seconds each (all under 12 seconds), including witness preparation.

Built for post-quantum security, Airbender Prime uses hash-based STARKs combining GKR sumcheck, WHIR polynomial commitments and BLAKE2s hashing, with L1 proofs using Keccak-256-based commitments instead of BN254 pairings. It is based on the open RISC-V standard and pairs real-time proving with a standalone verifier for independent verification. ZKsync framed the prover as a building block for Ethereum's ZK-centric roadmap. Full details in the announcement.

GRVT, a crypto derivatives exchange, said it settles on ZKsync, calling it "the infrastructure under everything we're building." The venue framed speed as solved and said verification is next, signaling continued reliance on ZKsync's ZK-rollup stack for its trading settlement.

• GRVT is an institutional-grade derivatives venue built on ZKsync's technology.
• The tweet positions ZKsync as the settlement backbone for GRVT's upcoming launch.

ZKsync's Prividium platform is expanding to Japan through a partnership with NexBridge, a Japanese digital financial infrastructure company. The two will bring Prividium to Japanese financial institutions and jointly develop use cases matched to local regulatory requirements.

Prividium is ZKsync's DLT platform for financial institutions, following the recent open-sourcing of its permissioning engine and Deutsche Bundesbank's self-hosted deployment in Germany.

ZKsync (Matter Labs) open-sourced Prividium's permissioning engine — the core that governs roles and access in its DLT platform for financial institutions — so institutions can run a permissioned chain from public code in their own environment. Deutsche Bundesbank, Germany's national central bank, is the first institution to deploy the open-source engine self-hosted, with both sides continuing work on the platform's architecture.

The release builds on ZKsync's Pontes protocol for tokenized settlement in central bank money, which the team framed as confirmation that tokenized central-bank settlement is becoming Europe's direction of travel. Announcing the move, ZKsync also pointed to the argument from the Hidden Forces podcast that for central banks, something open and decentralized can be trusted more than something closed.
