CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built to your exact specifications.
- Full-Cycle Development: From initial concept and
Solidity/Rustcoding to deployment, verification, and monitoring. - Security as Standard: Every contract undergoes formal verification and automated analysis with tools like
SlitherandMythX. - Gas Optimization: We write efficient code to minimize transaction fees, a critical factor for user adoption and protocol economics.
Deliver a secure, auditable, and performant smart contract foundation in as little as 2-4 weeks for an MVP.

Business Outcomes of a Custom Opcode Set
Beyond raw capability, a purpose-built opcode set delivers measurable business results: faster time-to-market, lower operational costs, and defensible technical moats.
01
Reduced Gas Costs & Higher Throughput
Optimize for your specific transaction patterns. We design opcodes that minimize computational overhead, directly lowering gas fees for your users and increasing the transactions per second (TPS) your application can handle.

PROVEN METHODOLOGY
Our Delivery Process: From Analysis to Mainnet
A structured, four-phase approach to deliver secure, high-performance custom opcodes that meet your exact protocol requirements.
01
Phase 1: Requirements & Architecture
We conduct a deep technical analysis of your protocol's needs, defining the opcode's purpose, gas cost model, and integration points with the EVM. This phase establishes the formal specification and security boundaries.

Phase 2: Implementation & Unit Testing
Our engineers write the core opcode logic in Go (Geth) or Rust (Reth), adhering to EVM semantics. We build a comprehensive test suite covering edge cases, invalid inputs, and gas consumption validation.

Phase 3: Integration & Security Audit
We integrate the opcode into a forked client and conduct internal fuzzing and formal verification. The code undergoes a mandatory external audit by firms like Trail of Bits or ConsenSys Diligence before proceeding.
