overview

CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3 experts.

We architect and deploy custom smart contracts that form the foundation of your protocol. Our development process is built on security-first principles and delivers audit-ready code from day one.

Full Lifecycle Development: From initial concept and Solidity/Rust coding to deployment on EVM or Solana.
Security by Design: Implementation of OpenZeppelin standards, formal verification, and comprehensive test suites.
Gas Optimization: Every contract is engineered for minimum execution cost and maximum efficiency on-chain.

We deliver contracts that are secure by default and built to scale, reducing your time-to-audit by weeks.

Our team specializes in complex DeFi primitives (AMMs, lending vaults), NFT ecosystems (ERC-721A, ERC-1155), and custom utility contracts. We provide complete technical documentation and a deployment package for seamless mainnet launch.

ENTERPRISE-GRADE ARCHITECTURE

Core Components of Our SBT Framework

Our modular SBT framework is engineered for production, combining battle-tested smart contract libraries with custom logic to deliver robust, scalable, and secure Sybil resistance for your application.

Modular Identity Registry

Deploy a custom, gas-optimized identity registry built on ERC-721 or ERC-1155 standards. We implement role-based permissioning, pausable contracts, and upgradeable proxies for future-proof governance.

ERC-721/1155

Standards

OpenZeppelin

Security Base

On-Chain Attestation Engine

Integrate verifiable credential issuance and revocation. Our system supports batch minting, off-chain signing with EIP-712, and on-chain validation to minimize gas costs for users.

Sybil Detection Logic Layer

Custom smart contract logic to enforce unique-human rules. We implement mechanisms like proof-of-personhood gateways, social graph analysis, and time-locked claims to prevent duplicate identities.

DELIVERABLES

Business Outcomes: Secure & Scalable Identity

Our SBT Sybil Resistance Design delivers verifiable, on-chain identity primitives that enable secure user verification and unlock new business models without compromising decentralization or performance.

On-Chain Reputation Graphs

We design and deploy custom SBT schemas that map user credentials, affiliations, and achievements into a portable, non-transferable reputation graph. This enables trustless verification for airdrops, governance, and gated access.

Sybil-Resistant Airdrop & Rewards

Implement SBT-gated distribution mechanisms that filter out bots and duplicate wallets, ensuring rewards reach real users. We deliver custom claim logic and merkle-tree distribution for gas efficiency.

Decentralized Governance & Voting

Build governance systems where voting power is derived from verified identity SBTs, not just token holdings. We deliver custom quorum logic and snapshot integrations to prevent vote manipulation.

Enterprise-Grade Security & Audits

All SBT logic and integration contracts undergo rigorous security review. We deliver audit-ready code following OpenZeppelin patterns and can facilitate third-party audits with firms like Trail of Bits or Quantstamp.

how-we-deliver

CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built for your specific business logic.

We architect and deploy custom Solidity/Rust smart contracts that are secure by design. Every contract undergoes a multi-stage audit process, including automated analysis, manual review, and formal verification for critical logic.

From Concept to Mainnet: We handle the full lifecycle—requirements, development, testing, deployment, and monitoring.
Compliance & Standards: Built to exact specifications, whether it's a custom ERC-20, ERC-721, or a novel protocol standard.
Gas Optimization: Contracts are optimized for minimum execution cost, a critical factor for user adoption and scalability.

Deploy with confidence. Our contracts power applications managing over $500M+ in on-chain value with a 0 critical vulnerability track record.

Soulbound Token Development FAQ

Common questions from CTOs and product leads about our Sybil-resistant Soulbound Token design and development process.

We follow a structured 4-phase engagement: 1) Discovery & Design (1 week): We analyze your use case, threat model, and finalize tokenomics. 2) Smart Contract Development (2-3 weeks): Build and unit test the core SBT logic and Sybil-resistance mechanisms. 3) Security Audit & Testing (1-2 weeks): Internal review followed by a formal audit from a partner firm like Quantstamp or CertiK. 4) Deployment & Integration (1 week): Mainnet deployment and integration support with your frontend. We provide weekly demos and maintain a shared Jira board for full transparency.
