About the technology
Smart contracts
Solidity is a statically typed programming language for writing smart contracts on Ethereum and other Ethereum Virtual Machine networks. These contracts run on a blockchain and enforce rules for tokens, payments, ownership, governance and decentralized applications without relying on a central operator.
Core applications
Solidity specialists turn business rules into contract logic that can be deployed and called through wallets, web applications and blockchain protocols.
- Fungible and non-fungible token contracts
- Decentralized finance protocols and liquidity systems
- DAOs, voting and treasury controls
- Escrow, marketplace and payment workflows
- Upgradeable contract architectures
Ecosystem and tooling
The work sits within the Ethereum ecosystem and commonly includes EVM-compatible chains, OpenZeppelin libraries and wallet integrations. Professionals use development environments such as Hardhat and Foundry, along with JavaScript or TypeScript tooling, RPC providers, block explorers and contract verification services.
When expertise matters
Companies bring in freelance Solidity expertise when a contract will hold assets, expose a public protocol or need independent review before deployment. Specialists are also useful when an existing codebase needs gas optimization, migration to another EVM network, incident analysis or a controlled upgrade path. Teams in Germany may choose remote collaboration or on-site workshops depending on security and product requirements.
Safe delivery
Strong professionals begin with a clear threat model and explicit contract invariants. They write unit, integration, fuzz and invariant tests, inspect access control and upgrade mechanisms, and review reentrancy, oracle, arithmetic and signature risks. They also document deployment procedures, key responsibilities and emergency controls.
Choosing a specialist
Look for evidence of shipped contracts, readable repositories and disciplined review practices rather than familiarity with syntax alone. A capable Solidity expert can explain trade-offs between immutable and upgradeable designs, estimate gas behavior, work with auditors and communicate clearly with product, legal and security stakeholders. For Germany-based teams, language and availability should match the collaboration model.
Frequently asked questions
Before you brief your next project: the most common questions about Solidity.
Solidity is used to create smart contracts for Ethereum and EVM-compatible blockchains. Companies use it for tokens, decentralized finance, marketplaces, governance systems, escrow logic and other applications where rules must execute transparently on-chain.
Solidity is the most established language in the Ethereum ecosystem and has broad tooling, library and audit support. Rust-based and Move-based alternatives can offer different safety or platform models, but the right choice depends on the target network, team skills and available ecosystem components.
A strong Solidity specialist often also understands EVM execution, gas costs, cryptographic signatures, wallet flows and blockchain security. Practical work may require TypeScript, frontend wallet integration, Hardhat or Foundry, OpenZeppelin libraries, RPC infrastructure and deployment automation.
The need depends on the contract’s value, complexity and exposure. A simple internal prototype may need focused implementation support, while a public protocol should involve a seasoned Solidity professional who can design tests, threat models, upgrade controls and an audit-ready release process.
Yes. Solidity work is well suited to remote collaboration through shared repositories, review tools, test networks and structured security workshops. Germany-based companies should agree on working hours, documentation standards, language expectations and access controls before sharing sensitive deployment information.
Review deployed contract addresses, source repositories, test coverage and the specialist’s explanations of security trade-offs. High-quality Solidity work includes clear access control, defensive handling of external calls, predictable upgrade behavior, gas awareness and documentation that another professional can verify.
Some Solidity professionals specialize in implementation, while others focus on independent audits and security reviews. Ask whether the freelancer can identify reentrancy, authorization, oracle, accounting and upgrade risks, and whether the engagement should be followed by a separate review for independence.
A Solidity assignment should define the target chain, compiler constraints, contract standards, upgrade model, testing expectations and deployment ownership. Freelancers should also clarify whether they are responsible for implementation, integration, audit preparation, incident response or ongoing protocol maintenance.
The average hourly rate of freelancers in Germany who have used Solidity in their recent projects is 89 €, which corresponds to a daily rate of about 709 € based on an 8-hour working day.
Of the freelancers in Germany who have used Solidity in their recent projects, 88% hold at least a Bachelor's degree and 65% hold at least a Master's degree.
On average, freelancers in Germany who have used Solidity in their recent projects have 15 years of professional experience, with a single engagement typically lasting around 2.2 years.
