Smart-contract development, blockchain integration, and on-chain product builds. EVM and Solana, Solidity and Anchor — the studio’s deepest specialty.
Solidity for EVM chains, Anchor for Solana. From simple ERC-20 launches to full DeFi protocol architecture.
Get startedPre-audit cleanup of existing contracts, integration with external auditors (CertiK and others), post-audit fixes.
Get startedOn-chain representation of real-world or in-protocol assets — RWA tokenization, in-game currencies, loyalty points.
Get startedConnect an existing web or mobile product to wallets, on-chain payments, NFTs, or crypto top-ups without rewriting your stack.
Get startedA few of the on-chain products from real projects. Live links and client names available on request.
Solidity-based DeFi protocol deployed across multiple EVM chains. Contracts passed external audit by CertiK. My scope of work covered core protocol design and on-chain logic, the integration layer connecting partner DeFi protocols, and the governance surface.
Backend for a Solana-based DEX automation platform — auto-sniping, limit orders, and pre-trade simulations that filter rug pulls and honeypots before a buy executes. Anchor programs, Solana web3 integration, and the Hono API service were delivered as part of this work.
Telegram Mini App that issues bank cards funded by crypto top-ups — users hold crypto, spend in fiat. The Express/MongoDB backend powering card issuance, top-up flows, and transaction history was delivered end-to-end. Live with an active user base.

Audit-ready process
Polygon dropped the Erigon namespace, Etherscan cut a fourth chain, Zapper's API goes dark tomorrow — this week's crypto infrastructure deprecations.
HAWK survived two years of expert review and did not survive a weekend with Anthropic's model. What that breaks is an assumption inside your architecture.
Auditors bill for time, and most of it goes on things you could hand over upfront. How to prepare a codebase so the audit finds bugs, not context.
