The premier Mantle-native gateway for Real-World Assets. Tokenize and invest in RWA invoices, leverage mETH for capital-efficient purchases, access universal credit via OAID, compose RWA into usable credit, trade freely in real value.
The first generation of tokenized Real-World Assets (RWAs) successfully moved ownership to the blockchain but failed to solve the utility and fairness challenges of high-frequency finance.
Traditional RWA sales happen behind closed doors or via static listings. This leads to fragmented liquidity and unfair pricing, where retail participants have zero visibility into the true market demand for an asset.
Currently, when a user buys a tokenized invoice, their capital is effectively "frozen" until maturity. The asset remains a dead weight in the wallet, unable to be used as collateral or leveraged without moving it to a specific, siloed lending protocol.
Most on-chain yield models favor the last holder. If an investor holds an asset for 90% of its duration but sells just before settlement, they often lose 100% of the accrued yield to the buyer. This discourages secondary market liquidity and penalizes long-term holders.
OpenAssets provides a deterministic lifecycle for RWAs on Mantle, ensuring every step—from issuance to settlement—is optimized for capital efficiency.
Standardization at the Core
We transform off-chain cash flows into ERC-3643 compliant tokens. Every asset follows a strict, non-reversible state machine on Mantle, ensuring institutional-grade auditability from the moment of issuance.
Flexible Capital Formation
Originators can choose the best pricing strategy for their asset:
- Fixed-Price Listings: Instant liquidity for standard, high-velocity invoices.
- Uniform-Price Auctions: Fair price discovery for unique or large-cohort assets, ensuring all investors pay the same clearing price.
Self-Amortizing Acquisition
Leveraging Mantle’s native mETH, users can acquire RWAs with high capital efficiency. The native staking yield of mETH is automatically harvested to service loan interest, allowing users to hold leveraged RWA positions with near zero out-of-pocket interest costs and at times earning even more.
Deposit Once, Borrow Everywhere
Your Open Access ID (OAID) acts as a universal credit identity. By decoupling collateral custody (Solvency Vault) from credit issuance, users can tap into multiple Mantle lending protocols and more using a single RWA collateral pool. No more moving assets, just portable, verifiable credit.
Eliminating Yield Sniping
Our Token-Day Engine calculates yield entitlement down to the second. By tracking the duration of ownership, we ensure yield is distributed fairly between all past and present holders. This mathematically guarantees returns for your exact period of risk.

TECHNICAL WALKTHROUGH
Guided demonstrations of our Mantle-native execution layer and RWA lifecycle.
The OpenAssets Client is a High-Fidelity State Interpreter. It coordinates seamlessly with our Mantle-native smart contracts and a dedicated backend indexing layer to provide institutional-grade performance.
- Real-Time Sync: Uses Redis-backed WebSockets to push live bid updates and health factor changes.
- Trustless Data: Critical financial metrics (LTV, Debt, Yield) are read directly from Mantle Sepolia.
- Role-Based UX: Optimized interfaces for both Issuers (Asset Tokenization) and Investors (Discovery & Credit).
We have curated a library of short, guided videos to demonstrate the core functionality of the protocol.
You can find all the walkthroughs on our website at once interactive section here > Walkthroughs

DEVELOPER ONBOARDING
Step-by-step guide to deploying the OpenAssets interface on your local machine.
Before you begin, ensure you have the following installed:
- Node.js: v20.x or higher (Recommended: v22 LTS)
- Package Manager:
npmorpnpm - Web3 Wallet: MetaMask or any mantle supporting wallet configured for the Mantle Sepolia Testnet.
- Mantle Faucet: Ensure you have test MNT for gas.
- Open Assets Backend Up: Ensure you have the server and contracts up. (Steps can be found here Backend Setup)
git clone https://github.com/TheOpenAssets/TOA-Client-Mantle.gitWe recommend using npm for consistent dependency resolution:
npm installThe application requires several contract addresses and API endpoints to function. Create a .env file in the root directory:
