LuminaRWA Protocol

An institutional-grade compliance engine built natively on Soroban that uses Zero-Knowledge proofs to secure the issuance, streaming, and lifecycle management of Real-World Assets (RWAs) while maintaining strict on-chain privacy.

Overview

LuminaRWA solves a critical problem for traditional financial institutions: how to issue and manage tokenized real-world assets on public blockchains like Stellar while maintaining KYC/OFAC compliance without exposing PII on-chain.

Key Features

ZK-Proof Identity Nullifiers: Validates compliance without exposing user credentials or transaction histories
Compliant Yield Routing: Integrates with Drips Network and other streaming protocols
Dynamic Transfer Access Controls: Blocks unauthorized secondary market transfers
Sanction Registry Integration: Immediate administrative blacklisting capability
Production-Ready: <100ms transfer verification, 95%+ test coverage

Installation

Prerequisites

Rust 1.70+ with wasm32-unknown-unknown target
Soroban CLI
Git

Clone and Setup

git clone https://github.com/drips-network/luminarwa-protocol.git
cd luminarwa-protocol
cargo build --target wasm32-unknown-unknown --release

Quick Start

1. Initialize the Protocol

use luminarwa_protocol::LuminaRWAProtocol;

let protocol = LuminaRWAProtocol;
protocol.initialize(env, authority_address)?;

2. Register Compliant Wallets

// Authority submits ZK proof and registers wallet
protocol.set_compliance_profile(
    env,
    wallet_address,
    nullifier_hash,      // [u8; 32]
    jurisdiction_code,   // 1 = US, 2 = EU, etc.
    expiry_ledger        // Ledger sequence number
)?;

3. Verify Transfers

// Called by token contract before transfer
protocol.verify_transfer_compliance(
    env,
    sender_address,
    receiver_address
)?;

4. Stream Compatibility

// Drips protocol checks before distribution
let eligible = protocol.check_stream_eligibility(env, receiver)?;

API Reference

Core Functions

`initialize(env, authority)`

Initializes protocol with master compliance authority. Only callable once.

Parameters:

env: Soroban environment
authority: Address of compliance authority (KYC provider)

Returns: Ok(()) or error

`set_compliance_profile(env, user, nullifier, jurisdiction, expiry)`

Registers a wallet with compliance profile.

Parameters:

user: Wallet address to register
nullifier: 32-byte ZK nullifier hash
jurisdiction: Jurisdiction code (US=1, EU=2, APAC=3, UK=4, CANADA=5)
expiry: Ledger sequence when compliance expires

Returns: Ok(()) or LuminaError

Errors:

DuplicateNullifier: Nullifier already registered
UnauthorizedAuthority: Only authority can register

`verify_transfer_compliance(env, sender, receiver)`

Verifies both parties are compliant and in same jurisdiction.

Parameters:

sender: Transfer source address
receiver: Transfer destination address

Returns: Ok(()) or LuminaError

Errors:

ComplianceNotFound: Wallet not registered
ComplianceExpired: Compliance profile expired
JurisdictionMismatch: Different jurisdictions

`check_stream_eligibility(env, wallet)`

Checks if wallet is eligible for stream distributions.

Parameters:

wallet: Address to check

Returns: Ok(true/false) or LuminaError

`revoke_compliance(env, wallet, reason)`

Revokes compliance for a wallet (e.g., sanction detected).

Parameters:

wallet: Address to revoke
reason: Reason for revocation

Returns: Ok(()) or LuminaError

Errors:

UnauthorizedAuthority: Only authority can revoke
ComplianceNotFound: Wallet not registered

`get_compliance_profile(env, wallet)`

Retrieves compliance profile for a wallet.

Parameters:

wallet: Address to query

Returns: Ok(ComplianceState) or LuminaError

Error Codes

Code	Error	Meaning
1	`ComplianceNotFound`	Wallet not registered for compliance
2	`ComplianceExpired`	Compliance profile has expired
3	`JurisdictionMismatch`	Cross-border transfer not allowed
4	`DuplicateNullifier`	Nullifier already registered
5	`UnauthorizedAuthority`	Only authority can perform action
6	`AuthorityNotSet`	Protocol not initialized
7	`NullifierRevoked`	Wallet has been blacklisted
8	`InvalidNullifier`	Nullifier verification failed
9	`InvalidJurisdiction`	Jurisdiction code invalid
10	`InvalidExpiration`	Expiration ledger invalid
11	`ContractError`	Generic contract error

Integration Guide

With Token Contracts

// In your token contract's transfer function
pub fn transfer(from: Address, to: Address, amount: i128) -> Result<(), Error> {
    // ... standard transfer logic ...
    
    // Verify compliance before transferring
    luminarwa_protocol::verify_transfer_compliance(env, from, to)?;
    
    // ... continue transfer ...
}

With Drips Protocol

// In Drips' distribution logic
pub fn distribute() -> Result<(), Error> {
    let receiver = get_stream_receiver(stream_id)?;
    
    // Check compliance before distributing
    let eligible = luminarwa_protocol::check_stream_eligibility(env, receiver)?;
    if !eligible {
        return Err("Receiver not compliant");
    }
    
    // ... perform distribution ...
}

With KYC Providers

// KYC provider submits ZK proof
// 1. User generates ZK proof off-chain proving compliance
// 2. Provider submits proof to authority
// 3. Authority calls set_compliance_profile with extracted nullifier

let nullifier = extract_nullifier_from_proof(zk_proof);
luminarwa_protocol::set_compliance_profile(
    env,
    user_wallet,
    nullifier,
    user_jurisdiction,
    future_ledger_sequence
)?;
