Production blockchain, DeFi, trading & AI systems

From custom consensus and app-chains to bridges and node infrastructure, we build the foundational blockchain systems other teams build on top of.

We write the contracts that hold real value — tested to invariants, fuzzed, formally specified where it counts, and ready for third-party audit.

We build Anchor and native Rust programs that use Solana's parallel execution and low fees the way they were meant to be used — not ported EVM logic.

We build and ship EVM applications end to end — contracts, indexing, account abstraction, and front ends — across Ethereum and the major L2s.

We build complete DeFi protocols — contracts, economic models, and the keeper and oracle infrastructure that keeps them running safely at scale.

We build decentralised and hybrid exchanges — AMM or order-book — with aggregation, MEV-aware routing, and the liquidity tooling traders expect.

We build the trading core, custody, and settlement systems behind centralised and hybrid exchanges — engineered for uptime, latency, and proof-of-reserves.

We build market-making, arbitrage, and algorithmic execution systems with the connectivity, risk controls, and observability that separate profit from disaster.

We build production AI agents with tool use, planning, evaluation, and guardrails — including agents that act on-chain under strict, auditable controls.

We design and build production SaaS platforms — multi-tenancy, billing, SSO, and an event-driven core — with the hard architecture done right from day one.

We design and build REST, GraphQL, and gRPC APIs with the versioning, auth, rate limiting, and documentation that make an API a dependable product.
