Explanation:
Access control bugs often have the highest real-world exploit probability in smart contracts because attackers can directly call privileged functions when role checks fail. In blockchain security audits, broken authorization logic is a common cause of fund loss and protocol takeover.
I’ve been reading more about security audits for blockchain-based casinos, and it feels different from the usual DeFi/protocol audits people discuss.
These systems handle real money, game logic, payouts, randomness,...
I recently had a blockchain developer interview where the panel asked me to compare zk-SNARKs and zk-STARKs “in practical engineering terms.” I understood the basic theory, but when they expected...

I’m interviewing for a Solidity/security role and the posting was “Remote (US)”. On the first call they mentioned “a few in-person weeks” in NYC/SF for team planning. I’m genuinely comfortable...
In a recent US DeFi team Solidity interview (remote loop), I got asked: “What are the risks of making an external call in a smart contract, and how would you...
I’m testing an upgradeable Solidity system (proxy pattern) and I’m realizing “tests passing” doesn’t automatically mean the upgrade is safe. The scary part is that upgrade failures can look fine...
I’m in late-stage interviews for a DeFi-focused Solidity developer role with a US-based team (remote). They’ve been clear that the offer will be contingent on a standard background check plus...
Yesterday I had a smart contract interview with a US-based Web3 startup (small team, very practical round). They went deep on EVM storage gas: SSTORE vs SLOAD, warm vs cold...
I’m a Solidity dev with ~4 years of experience, based in Germany. I’m applying to remote Web3 roles with US teams (protocol / DeFi / infra), but a lot of...
The term “Web3 experience” is so broad that I’m struggling to decode what US Web3 startups actually mean when they put it in a job description. A few roles even...
I’m seeing very different hiring behaviour for Solidity and Rust roles depending on whether the team is based in NYC, SF, or fully remote — and it’s most visible at...

Quick context before I sign anything — I’m sanity-checking: EP vs contractor/EOR, what “hybrid” actually means week-to-week, and whether the pay is mostly SGD or mostly token “upside”. Also trying...
