Smart Contracts That Survive Mainnet
Testnet is easy. Mainnet is where $200M exploits happen because someone forgot a reentrancy guard. We write smart contracts in Solidity and Rust, run formal verification where it matters, and get third-party audits before any code touches real funds.
What is Blockchain Development?
Blockchain development is the engineering of decentralized applications, smart contracts, and protocols that run on distributed ledger networks. This includes DeFi protocols, tokenization platforms, NFT marketplaces, DAOs, and enterprise blockchain solutions. The stakes are different from traditional software — deployed smart contracts are immutable (or upgradeable with proxy patterns, which carry their own risks). Bugs cost real money, usually someone else's money. Gas optimization matters because users pay for every computation. And security isn't a nice-to-have; it's the entire value proposition of running code on-chain instead of on a server you control.
- Smart contract development in Solidity (EVM chains) and Rust (Solana, Near)
- DeFi protocol engineering with formal verification for high-value contracts
- Gas optimization that reduces transaction costs by 30-60% on average
- Security-first development with pre-audit, audit, and post-deployment monitoring
What We Build On-Chain and Off-Chain
Full-stack blockchain development — from smart contracts to the frontends that interact with them.
Smart Contract Development
Solidity for EVM-compatible chains (Ethereum, Polygon, Arbitrum, Base), Rust for Solana and Near. Proxy patterns for upgradeability, gas optimization through storage packing, and factory patterns for scalable deployments.
Security Auditing & Formal Verification
Internal audit with Slither, Mythril, and Echidna fuzzing before engaging third-party auditors. Formal verification with Certora for high-value contracts. We fix vulnerabilities before auditors find them, which saves time and money.
DeFi Protocol Engineering
AMMs, lending protocols, yield aggregators, and liquidity mining systems. We've built protocols managing $40M+ TVL. Flash loan protection, oracle manipulation resistance, and economic attack modeling included.
Token Engineering & Tokenomics
ERC-20, ERC-721, ERC-1155, and custom token standards. Vesting contracts, staking mechanisms, and governance tokens with on-chain voting. Token economic modeling to prevent inflation death spirals before they start.
Layer 2 & Scaling Solutions
Deployments on Arbitrum, Optimism, Base, Polygon zkEVM, and StarkNet. Bridge integration, cross-chain messaging via LayerZero and Axelar, and rollup-specific optimizations that reduce gas costs by 90%+ vs L1.
Web3 Frontend & Wallet Integration
React/Next.js dApps with wagmi, viem, and WalletConnect. Multi-wallet support (MetaMask, Coinbase Wallet, WalletConnect), transaction simulation previews, and gas estimation UIs that don't confuse users.
Who Needs Blockchain Development?
Blockchain makes sense when trust, transparency, or disintermediation create real value. Here's where.
DeFi Protocols
Decentralized exchanges, lending markets, and yield protocols. We built an AMM on Arbitrum that reached $12M TVL in its first month with zero security incidents. Gas-optimized contracts that save users $2-5 per transaction vs competitors.
Asset Tokenization Platforms
Tokenize real estate, securities, commodities, or intellectual property. ERC-3643 compliance for security tokens with transfer restrictions, dividend distribution, and cap table management on-chain.
Enterprise Blockchain Solutions
Supply chain provenance, cross-organizational data sharing, and settlement systems. Private/permissioned deployments on Hyperledger Besu or Polygon Supernets when public chain transparency isn't appropriate.
Gaming & Digital Collectibles
On-chain game economies, NFT marketplaces, and player-owned asset systems. ERC-1155 multi-token contracts for in-game items with off-chain metadata and IPFS/Arweave storage for permanence.
How We Build Blockchain Applications
Blockchain development with an obsessive focus on security — because on-chain mistakes are permanent.
Protocol Design & Economic Modeling
We define the on-chain vs off-chain boundary, model token economics with agent-based simulations, and identify attack vectors before writing code. The design phase is where you prevent $100M exploits, not the audit phase.
Smart Contract Development
Solidity or Rust development following established patterns (OpenZeppelin, Solmate). Full unit tests, integration tests, and invariant fuzzing with Foundry. Every function gets a NatSpec comment explaining its purpose and access controls.
Internal Security Review
Automated analysis with Slither and Mythril, manual code review by a second engineer, and invariant testing with Echidna. We catch 90% of issues internally so the external audit focuses on subtle economic and logic vulnerabilities.
Third-Party Audit & Remediation
We engage reputable audit firms (Trail of Bits, OpenZeppelin, Spearbit) and manage the audit process. All findings get fixed and re-reviewed. The audit report is published publicly — transparency builds trust with users.
Mainnet Deployment & Monitoring
Deterministic deployment scripts, multi-sig controlled ownership, and timelocks on admin functions. Post-deployment monitoring with Forta agents and custom alerting for unusual contract interactions. Bug bounty program setup on Immunefi.

Blockchain Development Questions Answered
Quick answers to the questions we hear most often.
It depends on your use case. Ethereum for maximum security and DeFi composability. Arbitrum or Base for lower gas costs with Ethereum security. Solana for high-throughput applications where sub-second finality matters. Polygon for projects that need low fees and broad wallet support. We help you pick based on your technical requirements, not chain tribalism.
