Hire Smart Contract Developers
Smart contract developers write the on-chain code that holds and moves digital assets, where mistakes are public and often permanent.
The role
What smart contract developers do
A smart contract developer models the rules of your system as code, writes extensive tests, reviews for known exploit patterns, and plans deployment and upgrade strategies. On Ethereum-compatible chains that means Solidity; on Solana, usually Rust.
Typical deliverables
- Token, NFT, staking or escrow contracts
- Test suites with edge cases
- Deployment and verification scripts
- Upgrade and access control design
- Documentation for auditors
Tools you will see
- Solidity
- Rust and Anchor
- Foundry or Hardhat
- OpenZeppelin
- Static analysis tools
Choosing
How to choose smart contract developers

- Past audit reports they worked through.
Questions to ask
- 1What could go wrong with this contract?
- 2Who should have admin permissions, if anyone?
- 3How will users' funds be protected?
- 4How do you prepare code for an audit?
Planning
Before you post the job
Audits
Any contract holding significant value should be independently audited before mainnet launch.
What drives cost
Logic complexity, value at risk, number of contracts and testing depth.

FAQ
Questions about hiring smart contract developers
What is a smart contract audit?
An independent security review of contract code before launch.
Can bugs be fixed after launch?
Only with upgradeable designs or migration to new contracts, both of which add complexity.
Rust or Solidity?
Solidity for Ethereum and EVM chains; Rust for Solana and some other chains.
