neonlabsorg/neon-evm v0.4.0

on GitHub

1. Change fields of the Storage structure. This structure is used to hold the state of EVM between iterations. Since we have not yet launched in the MainNet, a simplified way of changing this structure was chosen (without introducing an additional version of the structure). Therefore, when upgrading from an older version, you must ensure that all iterative transactions are completed.

2. Changed instructions:

   • Write (0) -> WriteHolder (18)
   • PartialCallFromRawEthereumTX (9) -> PartialCallFromRawEthereumTXv02 (19)
   • Continue (10) -> ContinueV02 (20)
   • Cancel (12) -> CancelWithNonce (21)
   • ExecuteTrxFromAccountDataIterative (11) -> ExecuteTrxFromAccountDataIterativeV02 (22)

3. Changed ELF parameters:

   • add NEON_PAYMENT_TO_TREASURE
   • add NEON_PAYMENT_TO_DEPOSIT
   • add NEON_CHAIN_ID
