TL;DR
RWA Vaults are ERC-4626 onchain containers for yield-bearing tokenized real-world assets: money market funds, corporate bonds, BTC-collateralized fixed income, private credit. Underlying assets sit with licensed custodians. The Vault token is the onchain claim. Three things matter: ERC-4626 makes every Vault composable across DeFi, the Bahamas DARE Act perimeter keeps the assets institutionally legible, and Vaults are architected for two surfaces. Authorised and Autonomous vaults.
Why this matters
The category "tokenized real-world assets" is now broad enough to be meaningless on its own. Treasuries, private credit, real estate, equities, commodities, structured products. All sit under the RWA umbrella. The question that matters is not whether something is tokenized but how it is wrapped, who custodies the underlying, and how the onchain claim behaves once it lands in a wallet. RWA Vaults are an architectural answer to that question. The Vault is the wrapper, the standard, and the rail.
What are RWA Vaults?
An RWA Vault is an onchain smart contract that holds a tokenized claim on a real-world asset and issues a fungible token representing a depositor's pro-rata share. The contract follows the ERC-4626 standard, which defines how deposits,redemptions, vault token accounting, and yield accrual work for tokenized vaults.
The underlying asset is held by a licensed custodian. That asset might be a money market fund, a corporate bond, a BTC-collateralized fixed-income product, or a private credit position. The Vault contract issues an ERC-4626 vaulttoken onchain. The depositor holds that vault token. Yield accrues in the Vault and is either reflected in the vaulttoken's value or distributed onchain.
IXS Vaults are deployed across 10+ blockchains, including BTC. The same Vault product can be addressed by a wallet, a smart contract, or (in the agent-addressable variant currently in testing) an autonomous AI agent.
Why ERC-4626 for tokenized real-world assets?
When we picked an onchain standard for IXS Vaults, the choice came down to one question. What makes the asset most useful once it is tokenized?
ERC-4626 won because composability matters more than restriction. The standard is the same shape DeFi already speaks. Yield strategies, lending markets, agent frameworks, treasury tooling all integrate ERC-4626 by default. A tokenized treasury Vault that follows the standard plugs into the rest of the onchain economy without bespoke integration work on either side.
The alternative would have been a permissioned token standard built specifically for securities. Narrower, harder to integrate, optimized for the issuer rather than the holder. That tradeoff makes sense for some issuers. It makes less sense if you are trying to build the rail that AI agents and DeFi protocols will eventually transact on at scale.
The compliance perimeter does not live in the token standard. It lives in the licensed entity issuing the Vault, the custodian holding the underlying, and the KYC layer at the deposit interface. That separation is what makes ERC-4626 plus licensed RWAs work. Open standard, regulated wrapper.
What's inside an IXS Vault?
The IXS Vault product surface as of mid-2026:
- Fidelity USD Money Market Fund Vault. Tokenized exposure to a USD-denominated money market fund. Cash-equivalent yield, daily NAV reference, institutional-grade underlying.
- BlackRock Corporate Bond Vault. Tokenized exposure to BlackRock corporate bond positions. Investment-grade credit exposure in onchain form.
- BTC Real Yield Vault. BTC-collateralized fixed-income exposure. BTC holders earn dollar-denominated yield without converting to fiat or stablecoins. (Read the BTC Real Yield explainer.)
- Private Credit Vault. Tokenized private credit positions sourced from institutional originators.
Custody for the underlying runs through BitGo and Fireblocks. The Vault tokens themselves live onchain across the deployment chains.
Tokenized real-world assets carry risk, including potential capital loss.
How are IXS Vaults regulated?
IXS Finance is licensed under the Digital Assets and Registered Exchanges (DARE) Act by the Securities Commission of The Bahamas (April 2023). That license is the regulatory perimeter around the Vault product set. Issuance, trading, and settlement of tokenized digital assets happens inside it.
What the DARE perimeter means for a Vault depositor: the entity issuing the Vault is licensed, the custodian holding the underlying is licensed, and the activities the Vault enables (KYC'd deposit, redemption, secondary trading) sit inside a defined regulatory framework. The Vault is not a permissionless DeFi pool. It is a regulated product with an onchain interface.
Access requires KYC verification. Certain products are not available in all jurisdictions, including to US persons for specific offerings.
Vaults for Humans vs Vaults for Agents
IXS Vaults are architected for two surfaces.
Vaults for Humans is the live surface. Institutional allocators, treasuries, and qualified individual depositors access the Vaults through the IXS interface. Wallet connect, KYC, deposit, hold, redeem. Same ERC-4626 share tokens, same regulated underlying, same custody.
Vaults for Agents is in testing. The architecture is designed to provide agent-addressable access to the same regulated Vault product set. An autonomous AI agent operating a treasury, a portfolio strategy, or a yield optimization role is designed to deposit, hold, and redeem against those Vaults through programmatic interfaces, with the same custodian and compliance perimeter behind the underlying.
The thesis is that one Vault product set should serve both kinds of capital. A money market fund yield is the same yield whether the depositor is a human or a programmatic agent. The wrapper, custody, and license do not change. The interface does.

Where IXS fits
IXS Finance team has been building tokenized RWA infrastructure since 2018, with a combined seven years of regulatory licensing work to operate 2 licensed platforms. $88M+ raised on platform, 60+ institutional deals closed across private credit, real estate, funds, and structured products. The Vault product set is the front-end of that infrastructure. Custody runs through BitGo and Fireblocks. Distribution and liquidity partners include LINE, Union Chain, and Flowdesk. Deployment spans 10+ chains, including BTC and Union Chain. The regulated perimeter is the Bahamas DARE Act license. The product noun is Vaults. The dual-surface architecture is Vaults for Humans, live, and Vaults for Agents, in testing.
That's the entity. (For the full entity frame, see Is IXS a DEX?)
