4 years as a Salesforce dev — should I jump to Solidity now, or keep Salesforce as my safety net?
I’d say it’s a smart move only if you’re okay with uncertainty and you’re willing to be judged on output, not years of experience.The risk is real: Web3 hiring can freeze suddenly. Also, Solidity work is...

How to Land Account Abstraction Jobs (ERC-4337): Bundlers, Paymasters & Security Skills That Actually Get Hired
I’ve helped interview for a couple of Account Abstraction roles recently, and I can confirm: nobody expects juniors to show up with a fully battle-tested bundler in production. What we actually look for is structured understanding of the ER...

How do you prevent block.timestamp manipulation in Solidity smart contracts for time-sensitive auctions?
A stronger answer is not “never use block.timestamp,” and it is definitely not “just replace it with block.number.” The better Solidity answer is to treat on-chain time as approximate and then design the auction so a small timing shift cann...

Ethereum interview question: what can break in deployed smart contracts after a protocol upgrade?
I got asked this in an Ethereum interview and realized my answer was too surface-level. When an Ethereum protocol upgrade or hard fork happens, deployed smart contracts don’t change because the bytecode is immutabl...

Layer-2 Solidity interview: what’s a sane event-logging + monitoring setup without bloating L1 data fees?
From the indexing side: the biggest gift you can give your future self is consistent event semantics. Teams get burned when they emit a lot, but the schema is inconsistent (same concept logged under 3 event names, different field ordering,...

Layer-2 Solidity interview: what’s a sane event-logging + monitoring setup without bloating L1 data fees?
On L2, I’d still think of logs as a cost center, because a lot of the “fee pain” comes from data posted to L1 (Optimism literally splits out an L1 Data Fee component). So my pattern is: events are an interface, not a diary. I emit few, stab...
