Smart Contract Development
Smart contract development demands precision - there are no second chances when code handles real money. Our team brings experience from building contracts for a $400M exchange and security expertise from government-grade crypto custody systems. We write contracts that are secure, auditable, and built to last.
Security-First Development
Our approach to smart contract development comes from experience where security failures are not an option. We served as the founding engineering team for a UK-based B2G crypto asset recovery platform - a system where government agencies depend on code integrity to seize and custody criminal cryptocurrency.
That same rigor applies to every contract we write. We have seen what happens when smart contracts fail: funds drained, protocols exploited, communities devastated. We build to prevent those outcomes.
When you work with Hexmount, you get a smart contract development company that treats your code like it handles millions - because it probably will.
Our Development Process
From specification to deployment, we follow a rigorous process that prioritizes security at every step.
Specification & Design
Document requirements, design contract architecture, and identify potential security risks before writing code.
Development & Testing
Write clean Solidity code with comprehensive unit tests, integration tests, and gas optimization.
Audit & Deploy
Internal security review, formal verification where applicable, and safe deployment with monitoring.
Smart Contract Services
From initial Solidity development through security auditing and optimization, we handle every phase of smart contract delivery.
Contract Development
Custom smart contract development from specification to deployment. We write clean, gas-optimized Solidity code with comprehensive test coverage and documentation.
Security Auditing
Thorough code review and vulnerability assessment. We identify reentrancy risks, overflow conditions, access control issues, and logic flaws before they become exploits.
Gas Optimization
Reduce transaction costs without sacrificing security. We refactor contract logic, optimize storage patterns, and minimize on-chain computation.
Upgradeable Contracts
Proxy patterns and upgrade mechanisms that let you improve your contracts over time. UUPS, transparent proxies, and diamond patterns implemented correctly.
Blockchain Platforms
We deploy to Ethereum and across the EVM ecosystem, choosing the right chain for your requirements and user base.
Ethereum & Solidity
Native Ethereum development with deep Solidity expertise. ERC-20, ERC-721, ERC-1155, and custom token standards.
Polygon & L2s
Layer 2 deployment for lower gas costs. Polygon, Arbitrum, Optimism, and Base chain development.
EVM-Compatible Chains
Cross-chain deployment to BNB Chain, Avalanche, Fantom, and other EVM networks with consistent security standards.
Multi-Chain Architecture
Contracts designed for cross-chain operation with bridge integrations and chain-agnostic patterns.
What We Build
From DeFi protocols to NFT systems, we develop smart contracts across the full spectrum of Web3 applications.
DeFi Protocols
Lending platforms, DEX liquidity pools, yield aggregators, and staking mechanisms. We understand DeFi economics and the security implications of composability.
Token Contracts
Standard and custom token implementations with vesting schedules, governance rights, transfer restrictions, and tax mechanisms built in.
NFT Systems
Generative collections, dynamic NFTs, royalty enforcement, and marketplace integrations. ERC-721 and ERC-1155 implementations optimized for your use case.
DAOs & Governance
On-chain governance with proposal systems, voting mechanisms, treasury management, and timelocks. Built for transparent, decentralized decision-making.
Escrow & Custody
Multi-signature wallets, time-locked releases, conditional payments, and trustless escrow systems. Security patterns proven at institutional scale.
Cross-Chain Bridges
Token bridges and cross-chain messaging. We have built protocols connecting blockchains that were not designed to communicate.
Our Security Approach
Every smart contract we deliver goes through a rigorous security process. We do not just write code - we actively try to break it before deployment.
Our smart contract audit process combines automated tooling with manual review. We check for known vulnerabilities, test edge cases, and analyze economic attack vectors that automated tools miss.
The result: contracts that have been stress-tested against real attack patterns before they ever hold user funds.
