Pull Request Overview
This pull request introduces comprehensive support for deterministic, human-readable word handles built on the BIP39 vocabulary standard, alongside significant improvements to contract compilation infrastructure, developer tooling, and multi-chain identity management. The implementation enables wallets to claim unique, memorable phrases (e.g., "ocean-guitar-sunset") that map directly to their Ethereum addresses through a new on-chain registry system.
Key Changes
- Word Handle System: New
AddressHandleRegistrysmart contract with BIP39 vocabulary support enables deterministic phrase claiming with validation, uniqueness guarantees, and multiple vocabulary support - Contract Compilation Refactor: Modular compilation scripts for
AddressClaim,AddressHandleRegistry, andBip39Vocabularywith automatic bytecode updates to environment variables - Enhanced Address Tracking:
AddressClaimcontract now efficiently tracks active claims with pagination support viagetClaimedAddressesPaginated()and related view functions

Line 92 has redundant type checking. The expression typeof encoded === 'string' ? ethers.getBytes(encoded) : ethers.getBytes(encoded) applies ethers.getBytes() in both branches, making the ternary operator unnecessary.

Line 815 includes a duplicate ABI entry. getTotalClaims() is already defined at line 57, making line 81's definition redundant.

This pull request introduces full support for deterministic, human-readable "word handles" using a new
AddressHandleRegistrysmart contract and BIP39 vocabulary, alongside major improvements to contract compilation, developer tooling, and documentation. TheAddressClaimcontract is also enhanced with efficient tracking and pagination of claimed addresses. The changes are organized into three main themes: new smart contracts and features, build tooling and scripts, and documentation/user experience.Key changes:
1. New Smart Contracts & Features
AddressHandleRegistry contract and interface:
Added
AddressHandleRegistry.solandIAddressHandleRegistry.solto enable wallets to claim unique, deterministic handles (BIP39 phrases) mapped to their address. Includes validation, uniqueness guarantees, and support for multiple vocabularies. [1] [2]BIP39 vocabulary integration:
The handle registry uses a vocabulary contract generated from the BIP39 English word list, enabling deterministic phrase handles.
Active claim tracking and pagination in AddressClaim:
The
AddressClaimcontract now tracks active claims, supports efficient addition/removal, and provides paginated queries for claimed addresses. [1] [2] [3] [4] [5]2. Build Tooling & Scripts
Modular contract compilation scripts:
Introduced separate scripts for compiling
AddressClaim,AddressHandleRegistry, and all contracts at once. Scripts also auto-generate the BIP39 vocabulary contract and update relevant.envvariables with bytecodes. [1] [2] [3] [4] [5] [6] [7]Environment variable management:
Updated
.env.exampleand added a shell script to manage contract and handle registry addresses per network, ensuring smooth local setup and CI/CD integration. [1] [2]3. Documentation & User Experience
Updated
README.mdandDOCUMENTATION.mdto explain word handles, how to deploy the registry, and how to enable/disable it per network. Also clarified compilation steps and feature lists. [1] [2] [3]These changes collectively enable a robust, multi-chain identity system with human-readable handles, improved contract management, and clear developer onboarding.
