CORE SERVICE
Smart Contract Development
Secure, audited smart contracts built to your exact specifications, from token standards to complex DeFi logic.
- Custom Logic: Build bespoke
ERC-20,ERC-721, orERC-1155tokens, DeFi protocols, DAO governance, and more. - Proven Security: Development follows OpenZeppelin standards, with formal verification and pre-audit reviews included.
- Full Lifecycle: We handle deployment, upgradeability planning (using proxies like
TransparentProxyorUUPS), and initial configuration.
Deliver a secure, functional smart contract system in as little as 2-4 weeks, accelerating your path to mainnet launch.

PREDICTABLE, TRANSPARENT, AND FAST
Our Delivery Process: From Specification to Production
A structured, four-phase approach that de-risks development, ensures alignment, and delivers production-ready SDKs and APIs on schedule. We focus on clear milestones, not just sprints.
01
Phase 1: Discovery & Specification
We conduct a technical deep-dive to define your exact requirements, target platforms (iOS, Android, Web), and data sources (on-chain, off-chain). Deliverables include a detailed technical specification and a fixed-scope, fixed-price proposal.
1-2 weeks
Duration
Fixed Scope
Output
02
Phase 2: Architecture & Core SDK Build
Our engineers design the SDK's modular architecture, implement core streaming logic (WebSocket/SSE), and build the first integration with your primary data source. You receive a functional prototype for early validation.
2-3 weeks
Duration
Working Prototype
Output
03
Phase 3: Integration, Testing & API Layer
We integrate all specified data sources, build the accompanying REST/GraphQL API, and implement comprehensive testing (unit, integration, load). Security audits and documentation are completed in parallel.
3-4 weeks
Duration
Audit-Ready Build
Output
04
Phase 4: Deployment & Handover
We deploy the SDK to package managers (npm, CocoaPods, Maven) and the API to your cloud environment (AWS, GCP). Full technical documentation, sample apps, and developer support ensure a smooth transition to your team.

Frequently Asked Questions
Get clear answers on our development process, timelines, and support for building your real-time data infrastructure.
A production-ready, fully audited SDK for a single protocol (e.g., Ethereum or Solana) typically takes 4-6 weeks. Complex multi-chain integrations or advanced features like historical data replay can extend this to 8-12 weeks. We provide a detailed sprint-by-sprint timeline after the initial discovery phase.
