What you need to know if you are deploying a new smart contract

  • The solidity compiler up to 0.8.23 version is now supported. Due to the new EIP-3855, it is possible to use the new instruction PUSH0, which pushes the constant value 0 onto the stack. Please note this is used by Solidity compiler from version 0.8.20. 
  • There are important changes in the deployment phase introduced by EIP-3860. 
    • The introduction of a maximum size limit for smart contract initcode.
    • The introduction of a charge of 2 gas for every 32-byte chunk of initcode.


List features from 1.2.0 to 1.3.0

Updated to the 0.11.0 SDK version

  • The 1.3.0 version has been updated to the 0.11.0 SDK version. See the SDK release notes for a detailed explanation.

Forger reward address

  • It is now possible to set up in the configuration the reward address that will be inserted in blocks produced by the forger. See SDK release notes for more details.
  •  If using docker, you can just configure the env property SCNODE_FORGER_REWARD_ADDRESS: the config file will be automatically generated accordingly.

Custom log4j file support in docker

Pause forging

  • Please be aware that starting from this version EON block production may temporarily pause if the mainchain block production slows down: EON forgers will automatically stop to produce new blocks if in the latest 99 EON Blocks no reference to mainchain blocks is present.

EIP-3651 Support

  • EIP-3651: Warm COINBASE: with this EIP, the forger address will be loaded at the beginning of a transaction in order to save some gas for the methods that use it.
