4. System Architecture

WalletTag is designed to be modular, scalable, and optimised for EVM-compatible chains — enabling flexible deployment and seamless integration into a wide range of Web3 platforms.

The protocol is composed of multiple layers, each contributing to intelligent wallet reputation scoring and real-time fraud detection.

• Issues on-chain tags as Soulbound NFTs or registry entries (e.g. Verified, Flagged, Monitored)

• Implements chain-specific logic to ensure gas-efficient tagging on EVM networks

Public Search Interface

• Allows anyone to check a wallet’s real-time risk score and trust tags

• Displays tag metadata, behavioral history, and any associated dispute records

REST API & SDKs

• Provides developers with easy access to WalletTag data

• Supports integrations into dApps, marketplaces, launchpads, domain registrars, and block explorers

Dispute Resolution Layer (Web3 Domains)

• Enables verified IP owners to submit claims for domain-based infringements

• Supports automated domain locking or transfer based on verified rulings and tag-triggered enforcement
