overview

CORE INFRASTRUCTURE

Smart Contract Development

Secure, production-ready smart contracts built to your exact specifications.

We architect and deploy custom Solidity and Rust smart contracts that form the foundation of your Web3 product. Our development process ensures security-first design, gas optimization, and comprehensive audit readiness from day one.

Custom Logic: Token systems (ERC-20, ERC-721, ERC-1155), DeFi protocols, DAO governance, and bespoke business logic.
Security Framework: Built with OpenZeppelin standards, formal verification practices, and automated testing suites.
Deployment & Management: Full lifecycle support from local development to mainnet deployment on EVM or Solana chains.

Reduce your time-to-market and technical risk with battle-tested contracts that just work.

We deliver production-grade code within 2-4 weeks for an MVP, backed by clear documentation and a 99.9% uptime SLA post-launch. Our focus is on creating secure, efficient, and maintainable contracts that scale with your user base.

PRODUCTION-READY XNFT INFRASTRUCTURE

Core Architectural Capabilities We Deliver

We architect and deploy secure, scalable xNFT protocols that enable seamless asset interoperability across major blockchains, reducing your time-to-market and technical risk.

Secure Cross-Chain Messaging Layer

Implementation of battle-tested bridging protocols (Wormhole, Axelar, LayerZero) with custom security modules. We deliver audited, non-custodial message passing that prevents double-spends and ensures atomic composability.

EXPLORE

Gas-Optimized Smart Contract Suite

Custom ERC-721x/1155 contracts with cross-chain state synchronization. Our architecture reduces gas costs by up to 40% for minting and transfers through efficient storage patterns and batch operations.

EXPLORE

Decentralized Relayer Network

Automated, fault-tolerant relayers for cross-chain transaction finality. We provision and monitor nodes across EVM, Solana, and Cosmos chains, guaranteeing sub-2-minute attestation times with 99.9% uptime SLA.

EXPLORE

Unified Metadata & Provenance Engine

On-chain and IPFS-based metadata resolution that persists across chains. We ensure trait consistency, verifiable ownership history, and royalty enforcement regardless of the asset's current network.

EXPLORE

Modular Protocol Governance

DAO-ready upgrade mechanisms and parameter controls using OpenZeppelin Governor. We implement secure, multi-sig guarded timelocks for protocol updates, fee changes, and supported chain management.

EXPLORE

Real-Time Monitoring & Analytics

Comprehensive dashboards for tracking cross-chain mint volume, bridge latency, and fee economics. We deliver alerts for failed transactions and liquidity thresholds, providing full operational visibility.

FROM CONCEPT TO PRODUCTION

Our Proven Delivery Methodology

We deliver secure, scalable xNFT architectures using a structured, milestone-driven process. This ensures predictable timelines, transparent communication, and production-ready infrastructure from day one.

Architecture & Design Sprint

We conduct a 2-week intensive sprint to define your xNFT protocol's core architecture, including cross-chain messaging strategy (LayerZero, Axelar, Wormhole), token standards (ERC-721, 1155), and gas optimization patterns.

Technical Deep Dive

xNFT Protocol Architecture: Key Questions

Get clear, specific answers to the most common questions CTOs and technical founders ask when evaluating an xNFT protocol development partner.

We follow a structured 4-phase methodology proven across 30+ Web3 projects:

Discovery & Design (1-2 weeks): We conduct a technical deep-dive to finalize architecture, tokenomics, and security requirements.
Core Protocol Development (3-5 weeks): Our senior Solidity engineers build the core smart contracts (minting, bridging, governance) using OpenZeppelin libraries and a multi-signature development wallet.
Security & Testing (2-3 weeks): Mandatory internal audits, unit/integration testing, and a testnet deployment precede a formal audit with a top-tier firm like CertiK or Quantstamp.
Deployment & Support (1 week+): We manage the mainnet deployment and provide 90 days of post-launch bug-fix support with optional extended SLAs.
