what is this, which is the hash value of an empty string in eoa and smart contract code included in ca
The hash value you’re asking about is the Keccak-256 of the empty string ,
which is:
0xc5d2460186f7233c927e7db2dcc703c0e500b653ca82273b7bfad8045d85a470
What it means
- For an EOA (externally owned account), the code hash is the hash of an empty string, because EOAs have no bytecode.
- For a smart contract account , the code hash is derived from the contract’s deployed bytecode, not the empty string.
Quick note
If you saw this in a quiz or forum post, the intended answer is usually the same exact 32-byte value above.
TL;DR:
0xc5d2460186f7233c927e7db2dcc703c0e500b653ca82273b7bfad8045d85a470
