About the technology

Smart contracts

Solidity is the main language for smart contracts on Ethereum and many EVM networks. Companies use it to build token logic, escrow flows, on-chain rules, and application backends that run on-chain instead of a server.

Where it fits

It is common in DeFi, NFT products, wallets, DAO tools, and blockchain games. Teams in Germany often need Solidity experts for product launches, protocol changes, audits, and upgrades that touch live contracts.

Tooling stack

  • Write contracts with Solidity and common OpenZeppelin components
  • Test with Hardhat, Foundry, and local EVM forks
  • Review gas use, access control, and upgrade paths
  • Connect contracts to front ends, indexers, and APIs

When to bring in help

Freelance specialists are useful when a team needs a contract review before deployment, a fast fix after a bug, or support for a new chain or protocol. They also help when the in-house team knows product work but needs deeper smart contract discipline.

What strong experts do

Good Solidity professionals think about security first. They check state changes, permissions, integer handling, event design, and how contracts behave under failure.

Delivery and collaboration

A strong setup includes clear specs, test cases, and an agreed deployment process. Remote work is common for Solidity projects, while workshops or final reviews in Germany can help when teams want tight coordination across product, legal, and security stakeholders.

Frequently asked questions

Before you brief your next project: the most common questions about Solidity.

Solidity is used to write smart contracts for Ethereum and other EVM chains. Companies use it for tokens, staking logic, trading rules, marketplaces, DAO workflows, and other on-chain processes that must run with clear and immutable rules.

Solidity is the standard choice when a project targets Ethereum-style chains. Rust is common on other ecosystems such as Solana or Polkadot, so the decision usually depends on the chain, the tooling, and the contract model the team needs.

Yes. A strong Solidity specialist usually understands security review, testing with Hardhat or Foundry, and how contracts connect to web apps, indexers, and wallet flows. Knowledge of Ethereum standards such as ERC-20 and ERC-721 is also useful.

For simple token or proof-of-concept work, a focused Solidity expert may be enough. For live contracts, upgrades, or anything handling value, teams usually want someone who has shipped reviewed code, writes tests carefully, and can explain tradeoffs clearly.

Yes, most Solidity work is remote-friendly because the code, tests, and reviews live in shared repositories. In Germany, on-site sessions are still helpful for kickoff meetings, security reviews, or signing off on a launch plan with product and compliance teams.

Ask for examples of contract types, testing habits, and security review approach. A strong Solidity professional can explain how they handle access control, upgradeability, reentrancy risk, and deployment steps without vague answers.

No. Solidity is most closely tied to Ethereum, but it is also used on many EVM-compatible networks. That is why teams building across chains often keep the same language while changing deployment, tooling, and network assumptions.

A good Solidity specialist understands that contract bugs can be expensive and hard to fix after deployment. They focus on precise logic, careful testing, and security-first design, not just on making the code compile.

The average hourly rate of freelancers in Germany who have used Solidity in their recent projects is 91 €, which corresponds to a daily rate of about 728 € based on an 8-hour working day.

Of the freelancers in Germany who have used Solidity in their recent projects, 87% hold at least a Bachelor's degree and 73% hold at least a Master's degree.

On average, freelancers in Germany who have used Solidity in their recent projects have 16 years of professional experience, with a single engagement typically lasting around 2.3 years.
