End-to-end
blockchain engineering.

Six service lines under one roof — architecture, contracts, dApps, AI, web and growth. You get a single accountable team from kick-off to mainnet and beyond.

01 / Protocols

Blockchain development

Custom L1 chains, L2 rollups, sidechains, bridges, validator and node infrastructure. Token economics, consensus tuning and high-throughput indexing built to survive real volume.

EVMSOLANACOSMOS SDKSUBSTRATE
02 / Contracts

Smart contract development & audits

Solidity, Vyper, Rust and Anchor contracts written test-first. Static analysis, Foundry fuzzing, formal verification and a paired third-party audit before any mainnet deployment.

SOLIDITYFOUNDRYSLITHERCERTORA
03 / dApps

Web3 dApps & DeFi platforms

DEXs, lending markets, staking, NFT marketplaces, DAO tooling and RWA platforms. Account abstraction, gasless UX and subgraph-powered data so users never see a failed tx.

04 / AI x Chain

AI + blockchain innovation

Autonomous on-chain agents, zkML and verifiable inference, AI-driven oracles, prediction markets and intent-based protocols — built where machine learning meets cryptography.

LLM AGENTSZKMLCHAINLINKEIGENLAYER
05 / Web

Web development

Marketing sites, investor decks, admin dashboards and protocol explorers built on Next.js — performant, accessible, SEO-clean and ready to plug straight into your contracts.

PR & press releases

Token announcements, listing news, milestone coverage and crisis comms placed across Cointelegraph, Decrypt, The Block, CoinDesk and tier-1 mainstream press — with a network of crypto journalists we've worked with for years.

PRESSNEWSWIREMEDIA KITOUTREACH
08 / Design

Web design

Conversion-focused product and marketing site design — wireframes, prototypes, design systems and pixel-tight UI built in Figma, then handed off ready for engineering.

FIGMAUXUIDESIGN SYSTEM

How we engage

Four phases. Fixed scope. No surprises at audit.

01

Discovery & spec

We map your protocol mechanics, token model, threat surface and compliance posture. Week one ends with a written technical spec, gas budget and fixed roadmap.

02

Architecture & design

Contract architecture, data model, indexers, frontend and oracle integrations are designed in lock-step — no orphaned services or last-minute glue code.

03

Build, test & audit

Test-first development with 95%+ coverage, fuzzing, internal review, formal verification where it counts, and a paired external audit before mainnet.

04

Launch & operate

Mainnet deployment, monitoring, incident playbooks and 24/7 on-call. We stay with you through TGE, listings and the first hundred days post-launch.
