We architect and deploy custom smart contracts that power your core business logic. Our team specializes in Solidity 0.8+ and Rust, implementing battle-tested patterns from OpenZeppelin and Solana Program Library to ensure security and gas efficiency from day one.
Multi-Chain Sybil-Resistant SDK Development
Smart Contract Development
Secure, production-ready smart contracts built for speed and compliance.
- From MVP to Mainnet: Go from concept to a fully audited, deployable contract in 2-4 weeks.
- Security-First: Every line undergoes peer review and is built for formal verification with tools like
SlitherandMythril. - Cross-Chain Ready: Deployments optimized for
EVMchains (Ethereum, Polygon, Arbitrum) andSolana.
We don't just write code; we deliver the immutable foundation for your token, DeFi protocol, or NFT platform with a 100% security audit track record.
Core SDK Capabilities We Deliver
Our Multi-Chain Sybil-Resistant SDK is engineered to provide the foundational security and interoperability your application requires. Each component is built, tested, and audited for enterprise-grade reliability.
Business Outcomes: From Integration to Impact
Our Multi-Chain Sybil-Resistant SDK delivers concrete, quantifiable value from day one. We focus on outcomes that accelerate your time-to-market, reduce operational overhead, and secure your user base.
Rapid Protocol Integration
Integrate our SDK and launch your sybil-resistant feature in under 2 weeks. We provide battle-tested modules for EVM chains (Ethereum, Polygon, Arbitrum) and Solana, with pre-configured attestation logic.
Reduced Fraud & Airdrop Costs
Cut airdrop waste and bot-driven fraud by over 90%. Our on-chain reputation scoring and multi-factored attestation prevent duplicate accounts and sybil attacks, ensuring rewards reach real users.
Scalable, Maintainable Architecture
Future-proof your application with a modular SDK built on OpenZeppelin standards and TypeScript. We deliver clean, documented code with upgrade patterns, reducing your long-term maintenance burden.
Compliance & Audit Readiness
Build with confidence using our audit-ready smart contracts and SDK components. Our development follows security best practices, making third-party audits by firms like Trail of Bits or CertiK faster and more cost-effective.

Our Delivery Process: From Spec to Production
We deliver production-ready, sybil-resistant SDKs through a rigorous, client-aligned process. Our phased approach ensures technical excellence, security, and seamless integration into your existing stack.
Phase 1: Discovery & Architecture
We conduct a deep technical discovery to define your multi-chain strategy, threat model, and SDK architecture. Deliverables include a detailed technical specification, integration roadmap, and a prioritized feature backlog.
Phase 2: Core SDK Development
Our engineers build the core sybil-resistance logic (e.g., proof-of-personhood, stake-based weighting) and multi-chain adapters for your target networks (EVM, Solana, Cosmos). All code follows security-first patterns.
Phase 4: Integration & Testing
We provide a staging SDK package and dedicated support to integrate it into your dApp. We conduct load testing, cross-chain simulation, and user scenario validation.
Phase 6: Ongoing Maintenance
Optional retainer for protocol upgrades, new chain integrations, and continuous security monitoring. We ensure your sybil resistance stays effective as the ecosystem evolves.
Built on Proven Protocols & Standards
Our SDK leverages battle-tested cryptographic primitives and industry-standard frameworks, ensuring your application inherits enterprise-grade security and interoperability from day one.
Frequently Asked Questions
Get clear answers on our development process, security, and timelines for building your custom SDK.
A production-ready, audited SDK for 2-3 target chains typically takes 4-6 weeks. This includes design, core development, integration testing, and a full security audit. For more complex deployments (5+ chains, custom consensus mechanisms), timelines extend to 8-12 weeks. We provide a detailed sprint-by-sprint roadmap during the initial scoping phase.
