Fields

source_code: SourceCodeMetadata

Includes metadata for compiler settings and language.

abi: String

The ABI of the contract.

contract_name: String

The name of the contract.

compiler_version: String

The version that this contract was compiled with. If it is a Vyper contract, it will start with “vyper:”.

optimization_used: u64

Whether the optimizer was used. This value should only be 0 or 1.

runs: u64

The number of optimizations performed.

constructor_arguments: Bytes

The constructor arguments the contract was deployed with.

evm_version: String

The version of the EVM the contract was deployed in. Can be either a variant of EvmVersion or “Default” which indicates the compiler’s default.

library: String

license_type: String

The license of the contract.

proxy: u64

Whether this contract is a proxy. This value should only be 0 or 1.

implementation: Option<Address>

If this contract is a proxy, the address of its implementation.

swarm_source: String

The swarm source of the contract.
