SolaryRWA — Tokenized T-Bills on Solana

Production-grade Real-World Asset (RWA) smart contracts for tokenized US Treasury Bills on Solana, built with Anchor 0.32.1, Solana 2.3, and Token-2022 v8.

Deposit USDC → receive yield-bearing tRWA tokens backed by T-Bills, with on-chain compliance, proof-of-reserves, and T+1 redemption.

Architecture

Five modular on-chain programs:

Program	Role
compliance-registry	KYC/AML identity, jurisdiction rules, transfer policy
transfer-hook	Token-2022 hook — enforces compliance on every transfer
token-controller	Token-2022 mint (InterestBearing, TransferHook, PermanentDelegate)
subscription-vault	USDC ↔ tRWA subscribe / redeem with NAV pricing
treasury-manager	Proof-of-Reserves attestations, AUM tracking, fees

See docs/ARCHITECTURE.md for the full system design.

Quick Start

Prerequisites

Install on Linux/macOS or WSL2 (recommended on Windows):

# Rust (1.89+ required by Anchor 0.32 IDL build)
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
rustup install 1.89.0 && rustup default 1.89.0

# Solana CLI (2.3.0 recommended)
sh -c "$(curl -sSfL https://release.anza.xyz/v2.3.0/install)"

# Anchor (AVM)
cargo install --git https://github.com/solana-foundation/anchor avm --locked
avm install 0.32.1 && avm use 0.32.1

# Node deps
npm install

Build & Test

anchor build
anchor keys sync    # writes unique program IDs
anchor test         # spins up local validator + runs tests

Deploy (localnet)

solana-test-validator   # separate terminal
anchor deploy
npx ts-node scripts/seed-compliance.ts

Key Features

• Token-2022 InterestBearing — native on-chain yield accrual (~5% APY from T-Bills)
• Transfer Hook compliance — every transfer checks KYC + jurisdiction
• NAV-based pricing — subscribe/redeem at fair value
• T+1 redemption queue — realistic settlement for T-Bill liquidity
• Proof of Reserves — on-chain attestations with collateralization floor
• PermanentDelegate clawback — regulatory recovery (governance-gated)
