Certified Blockchain Developer ? Ethereum (CBDE) Ethereum’s smart contract ecosystem assumes you’re comfortable with Solidity syntax, cryptographic hashing, and gas optimization concepts before exam day. Candidates lacking hands-on experience deploying contracts to testnets often struggle with transaction lifecycle questions. A working understanding of EVM opcodes and state management separates those who pass from those who don’t.
