Pioneering Self-Custody in Private Markets with The Industry Leading Compliant-Ready Wallet

Abstract

The transition of private market assets onto public blockchains requires a new generation of infrastructure that balances compliance with user empowerment. This whitepaper presents the ADDX Go Wallet, a pioneering self-custody solution designed specifically for the era of tokenized Real-World Assets (RWAs). It moves beyond the limitations of existing platforms to provide a secure, compliant, and user-centric gateway to the decentralized economy.

The ADDX Go Wallet is built on a robust Multi-Party Computation (MPC) framework that eliminates single points of failure while embedding regulatory oversight directly into its architecture. Its key innovation lies in using Soul-Bound Tokens (SBTs) to transform the wallet into an intelligent access tool, one that programmatically verifies investor eligibility before allowing interaction with regulated securities. This "compliance-by-design" approach is reinforced by a smart contract-level backstop, rendering non-compliant investments impossible.

Validated in a Proof of Concept aligned with the principles of MAS's Project Guardian, the ADDX Go Wallet demonstrates its readiness to set a new market standard. It offers financial institutions and investors a scalable, interoperable, and user-friendly platform that finally unlocks the promise of a truly global and liquid market for private assets.

Executive Summary

This paper details the architecture, security framework, and validated results of the ADDX Go Proof of Concept (PoC), a self-custody system engineered to address the fundamental infrastructure deficit in the tokenized Real-World Asset (RWA) market. Historically, private market platforms have operated on private, permissioned blockchains, which provided secure yet isolated "walled gardens." This paper contends that the subsequent phase of market expansion necessitates bridging these regulated assets to public blockchains.

The PoC validates a hybrid Multi-Party Computation and Threshold Signature Scheme (MPC-TSS) wallet architecture designed to serve as this critical conduit. Employing a {2,3}-threshold scheme, it establishes a "Compliance Bridge" for real-time policy enforcement while providing an "Escape Hatch" that ensures a provably non-custodial state for users. We elaborate on how this architecture securely anchors on-chain identity via Soul-Bound Tokens (SBTs) to programmatically govern user access to regulated offerings. Furthermore, we provide a thorough analysis of the security model, addressing risks such as collusion and application-layer threats. The outcomes of the PoC affirm the viability of this model as a secure, compliant, and scalable foundation to unlock the full potential of the RWA economy.
