Deployment Address Registry Publisher

WHAT IT DOES

Deployment Address Registry Publisher is a read-only developer tool that generates structured registry entries for deployed EVM smart contracts. It reads contract bytecode via eth_getCode to verify the address points to a valid contract, fetches account balance, block number, chain ID, and contract metadata, and produces comprehensive registry entries in both JSON and Markdown formats. The tool helps developers maintain a centralized record of deployed contract addresses, track deployment versions, document contract descriptions, and share deployment information with team members. It is essential for projects with multiple contracts across different environments (testnet, mainnet, local forks).

HOW TO USE

Connect your EVM-compatible wallet via the BGWallet bridge and select the network where your contract is deployed. Enter the contract name, address, optional version number, and optional description. Click "Publish Registry Entry" to generate a verified registry entry. Results include a summary of contract details (name, address, version, chain ID, block number, balance, contract status, bytecode size, registration timestamp), a JSON-formatted registry entry suitable for programmatic use, and a Markdown-formatted entry suitable for documentation or README files. The tool also provides copy buttons for both formats. All analysis is read-only—no signatures or transactions are submitted.

TECHNICAL MECHANISM

The tool uses ethers.js v5.7.2 to read chain state via the provider. It retrieves the contract bytecode via provider.getCode(address) to verify the contract exists and is deployed, balance via provider.getBalance(address) (converted to ETH), block number via provider.getBlockNumber(), and chain ID via provider.getNetwork(). The user-provided contract name, version, and description are combined with the on-chain data to produce a complete registry entry. The tool generates two output formats: JSON (structured data with all fields for programmatic use) and Markdown (human-readable documentation format). Each entry includes the contract name, address, version, chain ID, block number, balance in ETH, contract status (true/false), bytecode size in bytes, description, and registration timestamp. The tool does not store any data—all results are generated on-demand and displayed in the UI for the user to copy and save manually.

WHAT IT CANNOT SEE

This tool has fundamental limitations that users must understand. It cannot actually publish or store the registry anywhere persistent—the tool generates registry entries but does not integrate with any storage, database, or version control system. It cannot automatically detect contract deployments without user input—the user must provide the contract address. It cannot generate registry entries for contracts that are not deployed—the tool verifies bytecode presence before generating the entry. It cannot verify that the address corresponds to the intended contract version without source code matching—the tool only checks if the address is a contract, not which version. It cannot update or modify existing registry entries—the tool generates new entries but does not maintain a persistent registry. It cannot enforce uniqueness or prevent duplicate entries without manual review—the tool does not track previous entries. It cannot generate registry IDs or naming schemes without user input. It cannot verify the contract's ABI or source code. It cannot detect if the contract has been self-destructed or modified. The generated entries are templates for manual use and require the user to manage the registry storage.

PLEASE NOTE

This tool only supports EVM-compatible blockchains (Ethereum, Polygon, BSC, Avalanche C-Chain, Optimism, Arbitrum, and their testnets). Solana, Tron, Starknet, SUI, TON, Aptos, Bitcoin, Cosmos, and XRP are not supported. The tool is free, open-source, requires no API keys, and uses the wallet's native provider for all read operations. Registry entries are for documentation purposes—always verify contract addresses against the actual deployed source code before use.
