Machine Identity Manager

WHAT IT DOES

Machine Identity Manager gives IT administrators, security teams, and DevOps engineers a comprehensive tool for managing machine identities on-chain. It reads live on-chain data including machine identity records, device certificates, public key data, ownership records, registration timestamps, and contract state. You can register machine identities, update certificates, transfer ownership, revoke identities, and export identity records. The tool shows you in real time the machine ID, name, public key, owner, active status, identity count, and last update—so you can maintain a secure, tamper-proof inventory of machine identities.

HOW TO USE

Connect your EVM wallet (must be the contract owner or authorized address). Enter the identity manager contract address, machine ID, machine name, public key (hex), certificate data (hex), machine owner address, and metadata JSON. Use "Check manager state" to see the identity count, last update time, active status, and identity details for a specific ID. Click "Register identity" to create a new machine identity record. Use "Update certificate" to refresh certificate data. "Transfer ownership" changes the machine owner. "Revoke identity" permanently deactivates a machine identity. "Export identities" downloads the records as JSON. Each action generates a transaction you review and sign in your wallet.

TECHNICAL APPROACH

This tool interacts with machine identity manager contracts using ethers v5.7.2. It calls registerIdentity(), updateCertificate(), transferOwnership(), revokeIdentity(), getIdentity(), getIdentityCount(), getManagerConfig(), updateConfig(), and getLastUpdateTime() on the manager contract to manage and query identity state. Machine identities are registered with an ID, name, public key, certificate, owner, and metadata. Certificates can be updated while preserving the identity record. Revocation permanently deactivates identities. All RPC calls are wrapped in a robust error handler that extracts the actual failure reason from Ethers error objects, digging three levels deep to avoid showing "[object Object]" when a transaction reverts. Transaction costing uses receipt.effectiveGasPrice post-EIP-1559 rather than tx.gasPrice, which overstates actual spend.

WHAT IT CANNOT SEE

This tool cannot verify physical machine authenticity or guarantee that the machine matches the on-chain identity. It cannot detect if the machine has been compromised or tampered with. It cannot verify the identity of the machine owner beyond the on-chain address. It cannot see off-chain machine content or metadata not stored on-chain. It cannot guarantee that the identity records are complete or that all machines are registered. The tool provides machine identity management based on on-chain data, but it does not guarantee that the physical machine matches the records or that the records are complete.

PLEASE NOTE

This tool supports EVM‑compatible chains only (Ethereum, Goerli, Sepolia, Arbitrum, Optimism, Polygon). Solana, Tron, Starknet, SUI, TON, Aptos, Bitcoin, Cosmos, and XRP are not supported. This is a read‑write tool that requires signing transactions—always verify the manager contract address, machine ID, and owner before approving. No contract addresses are hardcoded; you paste the contracts you are managing. The tool is free and open under the BotGentz PLAYBOOK‑C specification.
