​
Parameters

  1. contract address (string, required): The address of the deployed contract

​
Response

The method returns an object containing the creator address and deployment transaction hash, or null if the address is not a contract or information is unavailable.

​
Response structure

  • hash — the transaction hash where the contract was created
  • creator — the address that deployed the contract

​

​
Contract creation methods

This method detects contracts created through:
  • Direct deployment transactions
  • CREATE opcode from other contracts
  • CREATE2 opcode for deterministic addresses

​
Use cases

The ots_getContractCreator method is essential for:
  • Contract verification: Verify the authenticity of contract deployments
  • Security auditing: Identify who deployed suspicious contracts
  • Attribution tracking: Link contracts to their deployers
  • Factory pattern analysis: Track contracts created by factory contracts
  • Deployment history: Research when and by whom contracts were deployed
  • Trust verification: Verify contracts were deployed by expected addresses
  • Forensic investigation: Trace the origin of malicious contracts
  • Documentation: Record deployment information for contract registries
  • Multi-sig verification: Confirm contracts deployed by authorized accounts
  • Development debugging: Track contract deployments during testing
This method is particularly valuable for security analysis and verifying the provenance of smart contracts in DeFi protocols.
