The ID for a smart contract instance
shardNum
The shard number (nonnegative)
realmNum
The realm number (nonnegative)
contractNum

evm_address
The 20-byte EVM address of the contract to call. Every contract has an EVM address determined by its shard.realm.num id. This address is as follows: The first 4 bytes are the big-endian representation of the shard. The next 8 bytes are the big-endian representation of the realm. The final 8 bytes are the big-endian representation of the number. Contracts created via CREATE2 have an additional, primary address that is derived from the specification, and does not have a simple relation to a shard.realm.num id. (Please do note that CREATE2 contracts can also be referenced by the three-part EVM address described above.)
