IoT Device Registrator

WHAT IT DOES

IoT Device Registrator gives manufacturers, system integrators, and device owners a comprehensive tool for registering and managing IoT devices on-chain. It reads live on-chain data including IoT device registrations, device metadata, ownership records, firmware version data, registration timestamps, and contract state. You can register devices, transfer device ownership, update device metadata, and export device records. The tool shows you in real time the device ID, name, type, firmware version, owner, registration timestamp, active status, and device count—so you can maintain a tamper-proof inventory of IoT devices.

HOW TO USE

Connect your EVM wallet (must be the contract owner or authorized address). Enter the registrator contract address, device ID, device name, device type, firmware version, device owner address, and metadata JSON. Use "Check registrator state" to see the device count, last update time, active status, and device details for a specific ID. Click "Register device" to create a new device record. Use "Transfer device" to update the device owner. "Update metadata" changes the device metadata. "Update config" changes active status and max size. "Export devices" downloads the records as JSON. Each action generates a transaction you review and sign in your wallet.

TECHNICAL APPROACH

This tool interacts with IoT device registrator contracts using ethers v5.7.2. It calls registerDevice(), transferDevice(), updateDeviceMetadata(), getDevice(), getDeviceCount(), getRegistratorConfig(), updateConfig(), and getLastUpdateTime() on the registrator contract to manage and query device state. Devices are registered with an ID, name, type, firmware version, owner, and metadata. Ownership transfers create immutable records. 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 device authenticity or guarantee that the device matches the on-chain record. It cannot detect if the physical device has been tampered with or replaced. It cannot verify the identity of the device owner beyond the on-chain address. It cannot see off-chain device content or metadata not stored on-chain. It cannot guarantee that the device records are complete or that all devices are registered. The tool provides IoT device registration based on on-chain data, but it does not guarantee that the physical device 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 registrator contract address, device 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.
