A smart contract developer writes, tests and deploys programs that run on a blockchain and execute automatically when conditions are met. Because contracts often hold value and are hard to change, buyers should weigh security track record above speed.
Formal verification uses mathematical proof to show that a program meets stated properties for every possible input. It goes beyond testing, which only covers the cases someone tried, and is increasingly used on high-value contracts.
A blockchain developer builds applications, smart contracts or core infrastructure on blockchain networks. The work ranges from protocol code to the services that connect users to chains, and hiring one makes sense when part of your product must run on a shared ledger.
ERC-20 is the standard interface for fungible tokens on Ethereum and compatible chains. It defines how balances, transfers and spending approvals work so any wallet or app can support a token.
Reentrancy is a smart contract vulnerability where an external call lets another contract call back in before the first call finishes. Attackers use it to act on stale state, often withdrawing funds repeatedly.
A Rust developer builds software in Rust, a systems language that offers high performance and memory safety without a garbage collector. Companies hire one for infrastructure, embedded or blockchain components where crashes or vulnerabilities are costly.
A smart contract is a program deployed on a blockchain that runs exactly as written whenever it is called. It can hold and move digital assets according to its own rules, without an intermediary.
