Flag CALLCODE as deprecated and suggest CALL/DELEGATECALL

Open vietlq opened this issue 6 years ago • 1 comments

CALLCODE is now deprecated and unsafe due to bug in implementation. People are advised to use CALL or DELEGATECALL instead.

Libraries

Libraries are similar to contracts, but their purpose is that they are deployed only once at a specific address and their code is reused using the DELEGATECALL (CALLCODE until Homestead) feature of the EVM.
