Stablecoins are a $319 billion market, and most of that capital earns nothing between transactions. If your platform holds stablecoin balances, that capital can be routed into a licensed RWA vault backed by real-world assets: money market funds, Treasuries, or private credit. This guide covers how the model works and how to integrate it.
TL;DR
The market is already moving, with platforms integrating yield in different forms, from DeFi lending to T-bill-backed products to RWA vaults.
For neobanks, adding a yield tier on idle float has become a practical response to compressing FX margins, with 76% of neobanks still unprofitable despite strong growth (CoinLaw, 2025). The same logic applies to crypto exchanges, yield apps, wallet providers, and payment platforms. Every platform holding stablecoin balances is sitting on an underused asset, and the infrastructure to put it to work now exists.
On yield sources, RWA vault infrastructure has practical advantages over DeFi for most regulated platforms:
For a platform already holding stablecoin balances, RWA vault infrastructure is a practical, compliant way to put that capital to work without building the underlying stack.
The flow is direct. Stablecoin capital routes into a licensed vault, the vault deploys into regulated real-world assets, those assets generate yield through real economic activity, and the yield is distributed back to the platform and its users.
Step 1: the platform connects to a licensed vault via API. Users on a fintech, exchange, or wallet connect to a licensed vault operator through an API. The stablecoin is routed to the vault without leaving the platform's interface.
Step 2: the vault deploys capital into regulated real-world assets. Capital is allocated into yield-generating instruments such as money market funds, US Treasuries, corporate bonds, or private credit, depending on the platform's preferred yield level and liquidity profile.
Step 3: returns are generated. Yield comes from interest paid by borrowers in a private-credit pool, bond coupons, or T-bill interest from a money market fund.
Step 4: yield is distributed and the platform earns a revenue share. Yield accrues daily and is credited to the platform's account. The platform decides how much to pass to users and earns a distribution fee on the AUM deployed through the vault.
Step 5: users redeem on demand. Settlement timelines vary by product, and each deal sets its own redemption and notice terms.
IXS runs a live suite of tokenized yield products that platform partners can access for regulated, asset-backed returns. Three are USDC-denominated and sit at the tiers most relevant to idle stablecoin balances. BTC Real Yield is Bitcoin-denominated and sits alongside them for platforms with BTC exposure.
Products sit in two vault structures. Permissioned vaults (details) are KYC-gated for institutions and regulated platforms. Permissionless vaults (details) are open-access on the ERC-4626 standard with no KYC at the protocol layer, built as the compliant rails for agentic finance. A platform partner can integrate either, depending on its users and regulatory setup. Integration is via API, with no licence required on the partner's side. Talk to us about a partnership.
The table below is an at-a-glance view of the indicative revenue opportunity by platform type.
Crypto exchanges and yield apps. An exchange can offer a yield product inside its existing interface and earn a revenue share on AUM deployed between trading cycles. A platform with $50 million in stablecoin balances routing through a 6% private-credit vault and retaining 50 basis points as a distribution fee generates roughly $250,000 a year in passive revenue, with no additional user acquisition. For a yield app already offering DeFi products, an RWA vault tier completes the menu: DeFi yield for users who accept rate variability, RWA vault yield for users who want predictable USD-denominated returns. With Aave's USDC yield around 3.1% (Aave, June 2026) and IXS RWA vault products at 4 to 12% depending on the asset, the RWA tier offers a materially better risk-adjusted return on the stable portion of a user's portfolio.
Neobanks and fintech platforms. The capital, stablecoin balances held between payment cycles, is already on the balance sheet. Adding a yield tier on that float can require no new user acquisition and no structural change to the payment product. Research cited by Rebelfi (March 2026) describes the standard split: platforms keep 15 to 30% of the yield and pass the rest to customers. On $100 million in balances at 8% annualised, that is $1.2 million to $2.4 million in annual revenue while offering users a 5.6 to 6.8% savings rate.
Payment processors. Corporate float held between payment and settlement is one of the most underused yield opportunities in stablecoin infrastructure. A processor holding client funds for 24 to 48 hours at scale has an addressable opportunity that generates revenue without touching the core payment product. An MMF vault with T+1 to T+2 liquidity is usually the right structure, letting capital earn during the settlement window and redeem when the payment clears.
Wallet providers. Wallets with large user bases can integrate RWA vault access via API, with the licensed vault operator handling compliance at the product level. Wallet users tend to hold stablecoin balances passively for long periods, which improves vault economics for both sides.
Whether you are depositing your own stablecoin treasury or offering yield to your users, the licensed infrastructure, legal structuring, asset-manager relationships, custody, compliance, and reporting, is handled by the vault operator. Building it from scratch takes significant upfront capital. A vault integration skips that. A licensed infrastructure operator handles:
Your integration work covers the API connection, the user-facing product design, and the commercial terms of the revenue share. A webview integration displays the vault inside your product through a hosted page and needs no heavy technical build. A full API integration gives direct access to the underlying functionality for a more custom, native experience.
Licensing. The operator should hold the licences relevant to the product and jurisdiction. IXS's infrastructure is built within a regulated framework, including the Bahamas DARE Act.
Asset-manager relationships. The quality of the underlying assets matters. Established institutional fund managers carry a meaningfully different risk profile from less-proven credit originators.
Integration options. A credible operator offers both lightweight and full API integration paths with realistic timelines, so a platform can pick its model based on technical resources and go-to-market timeline, and start light then upgrade as volume grows.
The simplest entry point is depositing your platform's stablecoin balances into a licensed vault to earn the returns generated by its underlying real-world assets. From there, platforms that want to offer yield to their users can move to an API integration.
IXS is a licensed RWA tokenization platform. Whether you want to earn yield on your own stablecoin treasury or offer a regulated yield product to your users, get in touch to start a conversation.
Do we need our own regulatory licence to offer this? In many structures, no. When you work with a licensed vault operator, the regulatory framework covering the product sits with the operator rather than the distribution partner. Whether that applies to you depends on your jurisdiction and the specific product structure. Seek appropriate regulatory advice before launching any yield product to users.
How long does integration take? A webview integration typically takes two to four weeks. A full API integration typically takes six to eight weeks. Neither requires your engineering team to build compliance, custody, or asset-management infrastructure.
What happens to user capital during the investment period? Capital is held within the licensed vault structure and invested in the underlying real-world assets. It is not commingled with the vault operator's balance sheet. Users redeem according to the vault's liquidity terms, typically T+1 to T+2 for money market products and longer for private credit.
Can we offer this alongside existing DeFi yield products? Yes. RWA vault yield and DeFi yield serve different preferences. DeFi yield suits users comfortable with rate variability and smart-contract exposure. RWA vault yield suits users who want stable, USD-denominated returns without crypto-market correlation. Running both gives your platform a complete yield menu.
Is the RWA yield USD-denominated? It depends on the product, the underlying asset, and the deal structure. On the IXS platform, current vault products are USD-denominated, with returns from USD assets including US Treasuries, money market funds, and corporate bonds.
