Solidity Developer for Hire

Solidity developer for hire with deep expertise in gas-optimized, security-focused smart contract development. Our team writes audit-ready code for DeFi protocols, token systems, and complex on-chain logic. We have shipped contracts securing hundreds of millions in value and served as founding engineers for government-grade crypto custody systems.

Why Solidity Expertise Matters

Smart contracts are unforgiving. Deployed code handles real money with no undo button. Here is why experienced Solidity developers make the difference.

Immutable Code, Real Money

Deployed smart contracts cannot be patched like web applications. One vulnerability can drain entire protocols. Solidity expertise means understanding attack vectors before they become exploits.

Gas Costs Compound

Inefficient code costs your users with every transaction. A few thousand gas saved per call translates to significant savings at scale. Optimization requires deep EVM knowledge.

Auditor Expectations

Security auditors look for specific patterns and anti-patterns. Code written by experienced Solidity developers passes review faster and with fewer findings.

Upgrade Complexity

Proxy patterns enable upgradeability but introduce storage collision risks, initialization bugs, and access control challenges. Experience prevents costly mistakes.

Our Solidity Development Capabilities

From DeFi protocols to custom token logic, we build secure smart contracts for production deployment.

DeFi Protocol Development

Lending platforms, DEXs, yield aggregators, and staking systems. We understand tokenomics and build contracts that create sustainable economic models.

Token Standards & Custom Logic

ERC-20, ERC-721, ERC-1155 implementations with vesting schedules, governance hooks, transfer restrictions, and custom mechanics tailored to your use case.

Upgradeable Contract Patterns

UUPS proxies, transparent proxies, and diamond patterns that allow your contracts to evolve. Proper initialization, storage layouts, and access control from day one.

Gas Optimization

Storage pattern optimization, calldata minimization, batch operations, and logic refactoring. We reduce transaction costs without compromising security or readability.

Security-First
Development

Every contract we write assumes adversarial conditions. We build for mainnet from the first line of code, not as an afterthought before deployment.

Our security practices come from building systems where failure was not an option. Government agencies depend on code we wrote for crypto asset custody. That same rigor applies to every Solidity contract we deliver.

We prepare contracts for external audit and work with security researchers. When auditors review our code, they find clean architecture and comprehensive test coverage, not a list of critical vulnerabilities.

Security Checklist

Reentrancy guards on all external calls
Access control with role-based permissions
Overflow protection and safe math
Check-effects-interactions pattern
Comprehensive unit and integration tests
Invariant testing and fuzz testing
Known vulnerability pattern detection
Economic attack vector analysis

Our Development Process

Structured workflow from requirements through deployment, with security verification at every stage.

1

Specification & Architecture

Document requirements, design contract structure, identify security considerations, and plan for upgradeability and gas efficiency.

2

Development & Testing

Write clean Solidity with comprehensive unit tests, integration tests, and fuzz testing. Every function validated against edge cases.

3

Security Review & Audit Prep

Internal security review, known vulnerability checks, documentation, and preparation for external audit. Issues fixed before deployment.

4

Deploy & Monitor

Careful testnet and mainnet deployment with contract verification, monitoring setup, and incident response procedures.

Why Hire Hexmount for Solidity Development

We combine deep Solidity expertise with real-world experience building applications that secure significant value.

Production-Tested Code

Our Solidity has secured smart contracts for exchanges reaching $400M market cap. We write code that handles real value at scale.

Government-Grade Security Background

Founding engineers for a UK B2G crypto asset recovery platform. National security requirements shaped our approach to every line of code.

Tiger Team Approach

Small, focused team of senior developers. You work directly with the engineers writing your contracts, not account managers who relay messages.
