Deutsche Bank, a bank managing $1.3 trillion in assets, just went live with blockchain-based settlement infrastructure built on ZKsync technology. The Memento ZK Chain, developed in collaboration with Memento Blockchain, launched on mainnet in May 2025. It runs as a private Layer 2 blockchain powered by ZKsync’s Prividium framework, settling transactions to Ethereum using zero-knowledge validity proofs.
What Deutsche Bank actually built
The chain integrates with Deutsche Bank’s DAMA 2 platform, which handles tokenized fund issuance, distribution, and servicing. The architecture is permissioned, with private data settling to Ethereum using ZK validity proofs. Zero-knowledge proofs let the bank prove transactions are valid without revealing the underlying data.
Fund deployment timelines have dropped from a typical 2-3 months down to 2-3 weeks.
This collaboration with Memento Blockchain traces back to around 2022, when the project began under the umbrella of the Monetary Authority of Singapore’s Project Guardian. Deutsche Bank’s deployment represents one of the first major implementations to graduate from that sandbox into live production.
