The table below defines the mapping of Solidity variables and operation codes to Hedera.
The address is a mapping of shard.realm.number (0.0.10) into a 20 byte Solidity address. The address can be a Hedera account ID or contract ID in Solidity format.
The BASEFEE opcode will return zero. Hedera does not use the Fee Market mechanism this is designed to support.
The CHAINID opcode will return 295(hex 0x0127) for mainnet, 296( hex 0x0128) for testnet, 297( hex 0x0129) for previewnet, and 298 (0x12A) for development networks.
The COINBASE operation will return the funding account (Hedera transaction fee collecting account 0.0.98).
The index of the record file (not recommended use block.timestamp).
The transaction consensus timestamp.
The GASLIMIT operation will return the gasLimit of the transaction. The transaction gasLimit will be the lowest of the gas limit requested in the transaction or a global upper gas limit configured for all smart contracts.
The address of the Hedera contract ID or account ID in Solidity format that called this contract. For the root level or for delegate chains that go to root it is the account ID paying for the transaction.
The value associated to the transaction associated in tinybar.
The account ID paying for the transaction, regardless of depth.
Fixed (varies with the global fee schedule and exchange rate).
selfdestruct(address payable recipient)
Address will not be reusable due to Hedera’s account numbering policies.
Precompile contract addresses will report no code, including HTS System contract.
Precompile contract addresses will report the empty code hash.
This opcode will operate as expected with no change from Ethereum Mainnet.
The CREATE2 operation is supported as of the 0.23 Hedera services release. Please check out the status page for network availabilty.
