CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
- Full Development Lifecycle: From specification and
Solidity/Rustcoding to testing, deployment, and verification. - Security-First: Contracts are built with OpenZeppelin standards and undergo rigorous internal review before external audit.
- Measurable Outcomes: Achieve 99.9% uptime SLAs, reduce gas costs by up to 40%, and deploy a secure MVP in as little as 3 weeks.
We don't just write code; we deliver the foundational, trustless logic that powers your product's core value proposition.

PROVEN PROCESS
Our Migration Methodology
A structured, risk-mitigated approach to modernizing your financial infrastructure. We ensure zero downtime, data integrity, and a seamless transition from legacy systems to a scalable blockchain foundation.
01
Discovery & Architecture Design
We conduct a comprehensive audit of your existing systems to map business logic, data flows, and dependencies. This phase defines the target blockchain architecture (EVM, Solana, Cosmos) and migration strategy.

Smart Contract Development & Audit
Our engineers build the core on-chain logic using Solidity, Rust, or CosmWasm. Every contract undergoes rigorous internal review and formal verification by third-party auditors like CertiK or Quantstamp before deployment.

Data Migration & Bridge Implementation
We design and execute secure, verifiable data migration pipelines. For hybrid systems, we implement robust, non-custodial bridges (e.g., Axelar, Wormhole) or custom oracles to ensure real-time sync between legacy and new systems.

PROVEN METHODOLOGY
Our Four-Phase Delivery Process
A structured, risk-mitigated approach to migrating your core business logic from legacy databases to a secure, scalable blockchain. We deliver a production-ready system, not just a proof-of-concept.
01
Phase 1: Discovery & Architecture
We conduct a deep technical audit of your existing system to map data flows, business rules, and dependencies. This phase delivers a detailed migration blueprint, smart contract architecture, and a phased rollout plan with clear success metrics.

Technical & Process Details
Legacy Migration FAQs
Answers to the most common questions CTOs and engineering leads ask when planning a legacy system migration to blockchain.
Our standard migration projects deploy to mainnet in 6-12 weeks. The timeline is broken into phases: 2 weeks for architecture & planning, 3-6 weeks for core development and smart contract auditing, and 1-2 weeks for deployment and integration. Complex systems with extensive off-chain logic or multi-chain requirements may extend to 16 weeks. We provide a detailed, phase-gated project plan at kickoff.
