overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3 experts to power your dApp.

We architect and deploy custom smart contracts on EVM and Solana that are secure by design. Our development process includes formal verification and third-party audits to eliminate vulnerabilities before mainnet launch.

  • Full-Stack Development: From ERC-20 tokens and ERC-721 NFTs to complex DeFi protocols and DAO governance systems.
  • Security-First Approach: Built with OpenZeppelin standards, tested with Foundry/Hardhat, and audited by firms like CertiK and Quantstamp.
  • Gas Optimization: We reduce transaction costs by up to 40% through efficient code patterns and storage optimization.

Deliver a market-ready, audited contract suite in as little as 4 weeks, with guaranteed post-deployment support and upgradeability.

Outcomes for Your Protocol

We design and implement custom jury selection and reputation systems that directly enhance protocol security, governance, and user trust. Here’s what you can expect from our engagement.

01

Custom Jury Selection Engine

A purpose-built, on-chain mechanism for selecting unbiased, qualified jurors for disputes or governance votes. We implement algorithms like sortition, stake-weighted selection, or reputation-based filtering to ensure fairness and Sybil resistance.

BUILDING TRUST, NOT JUST CODE

Our Delivery Methodology

We architect reputation systems that are secure, scalable, and legally sound from day one. Our phased approach ensures your custom jury selection mechanism is delivered on time, on budget, and ready for production.

01

Phase 1: Architecture & Legal Review

We begin with a deep-dive workshop to define your governance model, dispute types, and legal compliance requirements. This phase produces a technical specification and a risk assessment report, ensuring the system's design aligns with your jurisdiction and use case.

Design Phase

Specification Lock
02

Phase 2: Core Protocol Development

Our engineers build the smart contract suite for juror selection, staking, and voting using battle-tested patterns (e.g., commit-reveal, quadratic voting). Every contract is developed in Solidity 0.8+ with OpenZeppelin libraries and includes comprehensive unit/integration tests.

4-6 weeks

Phase 3: Security Audit & Hardening

Before deployment, the entire system undergoes a rigorous security review. We partner with leading audit firms (e.g., Trail of Bits, ConsenSys Diligence) for an independent assessment, followed by remediation of all critical/high issues. This phase is non-negotiable for production systems.

Frequently Asked Questions

Get clear answers on our process, timeline, and technical approach for building on-chain dispute resolution and reputation frameworks.

A complete custom jury and reputation system typically takes 4-8 weeks from design to mainnet deployment. This includes a 1-week discovery phase, 2-3 weeks for smart contract development and internal testing, 1 week for a third-party audit, and 1-2 weeks for integration and final deployment. For simpler reputation modules, delivery can be as fast as 2-3 weeks.
