Blockchain software development for financial services and FinTech: smart contracts, multi-chain wallets, tokenization, KYC and AML systems and the infrastructure that runs them.

We have run 30+ smart contract audit engagements and 15+ Rust projects since 2019.

Production work on Ethereum, Polygon, Arbitrum, Optimism, Base, BSC, Avalanche, Solana and TON. Non-EVM is routine rather than an exception: Solana through Rust and Anchor, TON for Telegram mini-apps, CosmWasm for Cosmos.

Token standards: ERC-20, ERC-721, ERC-721A, ERC-1155, ERC-4626 and ERC-4337 account abstraction, plus ERC-3643 and ERC-1400 where transfers must be permissioned. Regulatory scope covers MiCA, PSD2, AML and Travel Rule.

Azure Kubernetes Service runs the nodes and the application tier. Azure Confidential Ledger provides a tamper-evident append-only record built on the Confidential Consortium Framework. Azure Key Vault and Managed HSM hold signing material. Azure SQL Database ledger covers relational records that need integrity guarantees. Azure Monitor supplies the operational baseline.

Microsoft retired Azure Blockchain Service in September 2021, so no first-party managed blockchain network exists today. We design either around Azure Confidential Ledger, where a permissioned integrity record is what the problem actually calls for, or around a ledger running on Azure Kubernetes Service where a full network is required.

Discovery comes first: data flows, parties, trust boundaries and the record that must be provable. You get a written feasibility verdict, including a recommendation not to proceed if a ledger is the wrong tool for the problem.

Architecture, build and audit follow. The engineers who write the contracts also audit them, so review is not handed to a team that has never shipped on the chain in question.

Funded startups past seed, operating businesses scaling a product that already works and enterprises moving an older stack onto current technology. Minimum engagement is $25,000.
