overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built for scale and compliance.

We architect and deploy custom Solidity/Rust smart contracts that power your core business logic. Our development process is built for security-first execution, integrating formal verification and comprehensive audit trails from day one.

  • Full lifecycle development from specification to mainnet deployment.
  • Gas-optimized code reducing user transaction costs by up to 40%.
  • Compliance-ready structures for ERC-20, ERC-721, and custom token standards.
  • Upgradeable architecture using Transparent Proxy or UUPS patterns.

Deploy battle-tested contracts with a 99.9% security audit score and full documentation in 4-6 weeks.

We provide more than code—we deliver a resilient foundation. Every contract includes automated testing suites, deployment scripts, and post-launch monitoring via our dashboard to ensure ongoing integrity and performance.

PROVEN FRAMEWORK

Our Methodology: Secure, Scalable DID Integration

We architect decentralized identity for Prediction NFTs using a battle-tested, four-phase framework. This ensures your platform is secure from day one, scales with your user base, and delivers a seamless, compliant experience.

01

Architecture & DID Standard Selection

We analyze your use case to select the optimal DID standard (W3C DID, ERC-725/735, or ERC-6551) and design a modular architecture. This future-proofs your platform, enabling easy upgrades and interoperability with other Web3 services.

Secure Smart Contract Development

Our engineers build custom, gas-optimized smart contracts for identity management, credential issuance, and NFT binding. Every contract follows OpenZeppelin security patterns and is written in Solidity 0.8+ for maximum safety.

Scalable Credential Infrastructure

We implement off-chain verifiable credential storage with on-chain proof verification (e.g., using IPFS + Ceramic). This balances user privacy with blockchain efficiency, keeping minting costs low as your user count grows into the millions.

Frequently Asked Questions on DID for Prediction NFTs

Get clear answers on integrating decentralized identity to secure user predictions, manage reputation, and ensure verifiable outcomes.

We implement a modular DID layer that interfaces with your existing smart contracts. Typically, we deploy a DID Registry (ERC-1056/ERC-725) and a Verifiable Credential manager. User predictions are signed and linked to their DID, creating an immutable, self-sovereign record. This allows for portable reputation scores and prevents Sybil attacks without requiring users to manage complex keys directly.
