How exchanges build an Earn product, and who pays the yield

An exchange can build its Earn product in-house, wire it straight into one lending protocol, or put white-label vaults behind its own Earn tab. The route you pick sets how fast you launch and which yield sources you can offer. It also sets how fees split between you, the vault provider and the asset manager running the strategy.

Since the GENIUS Act was signed on 18 July 2025, US stablecoin issuers can't pay holders a yield just for holding the token. An Earn product works differently: the customer swaps the stablecoin for a vault share, and the vault earns yield by lending the dollars, buying Treasury bills or running trading strategies. To build an Earn product, an exchange can build vaults in-house or integrate one lending protocol directly. Or it can deploy white-label vaults on an infrastructure provider, with a professional asset manager running the strategy.

Each route leaves different jobs with your team. The customer relationship, onboarding and compliance stay with the exchange in all three. What changes is who writes and audits the vault contracts, who picks the strategy, who calculates the share price every day and who processes withdrawals. Those jobs decide how many people you need, how long the launch takes and where your revenue comes from.

Three routes to an Earn product

The three routes differ mostly in how much of the stack your engineers own once it's live. In the table, "curator" means the asset manager that runs a vault's strategy inside limits the platform approves.

Most exchanges we talk to start with one conservative product. They add a second band once the first has a track record, usually after a few months of clean withdrawals and a yield history they can show to compliance and to customers.

Building Earn in-house means running a small asset manager

An exchange that builds in-house takes on every job a fund administrator and a portfolio manager would normally do. You write the vault contracts and pay for audits on every version. That's a standing cost. You pick venues, set position limits and monitor them around the clock. The share price has to be calculated from live positions, and withdrawals have to be queued and paid. Every customer's yield gets recorded for tax. Tria, a crypto neobank with users in more than 150 countries, listed the same jobs before it chose to integrate. Its list ran from strategy selection and manager oversight to withdrawal processing and yield accounting. Each one needs an owner. It also needs an escalation path and a way to prove to auditors that it ran correctly.

Building it yourself makes sense when you run a treasury desk at scale, have engineers who've shipped audited contracts before and want to keep the whole spread, which in practice describes a handful of the largest exchanges. For most platforms the fixed cost lands before the first customer deposit, and it grows with every new chain or strategy you add.

Integrating a protocol directly gives you one yield source

Direct integration connects your Earn tab to a single onchain lending market. Coinbase took this route in September 2025, when it added USDC lending routed into onchain lending vaults curated by Steakhouse Financial, with no lockups. Borrowers on the protocol pay the yield. The rate floats with demand.

The integration is lighter than a full build, though you still own the deposit and withdrawal flows, the daily reconciliation between your ledger and the protocol, and every customer disclosure about where the money goes and what can go wrong. The catch is range, at least for an exchange that wants more than one kind of yield on the menu within its first year or two. A lending market gives you lending yield. Adding tokenized T-bills or private credit later means a second integration, with its own contracts, audits and checks.

What does a white-label Earn product include?

A white-label Earn product splits the work between three parties, and each one is paid for its part. Think of a supermarket's own-brand range. The shop sets the shelf price and owns the customer, while a specialist manufacturer makes the goods to its spec. In Earn, the three parties are:

• The exchange owns the Earn tab, the brand, onboarding, KYC and customer support. You pick the vaults.
• The vault infrastructure provider runs the vault contracts, the onchain risk limits, the daily share price and withdrawal processing.
• The curator, typically a hedge fund or asset manager, runs the strategy inside the limits you approve. Some exchanges curate their own vaults instead.

The customer sits outside all three. They hold a vault share, a token for their slice of the vault's assets, and redeem it at the share price.

Tria built its Earn tab on the Upshift SDK and went live two weeks after starting the integration, in January 2026. It now runs three vaults across two chains, with strategies run by Sentora. The Tria case study puts deposits routed at more than $25M. A Tria customer taps Earn and signs once. The shares land in their own smart account.

It works for institutions too. Eligible Kraken Institutional clients allocate into permissioned vaults from their qualified custody account, announced on 15 July 2026. The receipt token goes back to the client's segregated custody account. It shows on the statement.

Who provides the yield in a white-label Earn product?

In a white-label Earn product the yield is paid by whoever sits on the other side of the vault's positions. That means borrowers on lending markets, the US Treasury through tokenized money market funds, or counterparties paying funding spreads. The curator chooses the mix, the vault infrastructure enforces its limits, and the exchange passes the net result to its customers.

Gross yield comes in from the sources at the bottom. The curator allocates into them and earns a performance fee, and the vault layer earns a management fee. The exchange takes its own platform fee or spread, and the customer gets what's left.

Upshift groups its vaults into three bands by what they hold. The yield options page sets out the menu, and every band keeps balances in USDC or USDT.

Bands are indicative yields of the underlying assets as of 28 September 2026. Rates float. None is guaranteed. Each band is a separate vault behind the same SDK. Adding core later needs no new build. Where stablecoin yield comes from covers each source in more depth, and tiered stablecoin yield covers how to present a menu to customers.

How does revenue share work in an Earn product?

Revenue in a white-label Earn product comes out of the gross yield before it reaches the customer. Each layer takes its fee at a different point. Upshift's vault fee schedule has three fees, and the exchange can add its own on top:

An exchange earns in one of four ways. Many combine two. You can set a platform fee or keep a spread between the vault's yield and the rate you show customers. You can take a share of the management fee on the balances you bring, under a distribution agreement. If you curate a vault yourself, the performance fee is yours. And if you'd rather pass the full yield to customers as a growth play, you can set your own fee at zero. Fee levels are set per vault and per partner (most providers don't publish their splits at all).

One public example sits on the issuer side. Circle's IPO filing showed Coinbase receiving 50% of the residual reserve income on USDC, as reported by Decrypt in April 2025. That arrangement pays a distributor for holding the stablecoin, which is a different deal from earning on an Earn product.

The rules that shape an Earn product

Stablecoin rules in the US and the EU target the issuer first, and the EU rules also reach the platform. Under section 4(a)(11) of the GENIUS Act, an issuer can't pay "any form of interest or yield (whether in cash, tokens, or other consideration) solely in connection with the holding, use, or retention" of the stablecoin. The return in an Earn product comes from a vault that lends, buys T-bills or runs a strategy instead. How the GENIUS and CLARITY Acts reshape stablecoin yield covers what the market structure bill may add.

MiCA goes further for e-money tokens such as USDC and EURC in the EU. Article 50 bars issuers from granting interest, and it also bars crypto-asset service providers from granting interest "when providing crypto-asset services related to e-money tokens". Any benefit tied to how long a holder keeps the token counts as interest, including benefits from third parties. EU platforms structure Earn around the vault position the customer holds. Counsel in each market should review the structure before launch, and what a MiCA licence covers sets out the licence side.

Risks to size before launch

Every Earn product carries smart contract and strategy risk, whichever route you pick. A bug in a vault or protocol contract can lose funds. Ask any provider for its audit history and for who can upgrade the code. Liquidity risk sits with withdrawals, since a vault can take longer to pay out than customers expect. A liquid buffer with instant redemption covers day-to-day outflows. Counterparty risk sits with borrowers and fund issuers, and per-counterparty caps keep any single one from dominating a vault. A stablecoin can also trade below $1 for a while, as how stablecoin depegs happen shows.

Always make sure to do your own research and be aware of the above and any other risks before depositing.

How Upshift fits an exchange's Earn product

Upshift is onchain yield infrastructure that lets fintechs and asset managers offer yield inside their own products. Partners start with 24/7 tokenized money market funds and add higher-yield strategies, from lending to basis trades, on the same integration. A professional curator runs each stablecoin, BTC or ETH vault within risk limits set in advance, and depositors keep custody of their vault shares throughout. You integrate the SDK once and pick vaults from the live catalog, or have one built to your mandate. You set the vault name, your fees and who can deposit. The exchanges and wallets page shows how a launch runs.

Upshift vaults held $423.4M on 2 October 2026, summed vault by vault. Every Upshift vault is priced and settled by Upshift, which validates the curator's net asset value before it reaches depositors. Curators who run their strategy through the Upshift prime stack also get a policy engine that limits activity by chain, protocol, token and contract function, access to an institutional lender network, and execution across onchain protocols and centralized venues from one smart contract account. The vault owner is a multisig. The contracts have been through 11 smart contract audits by 6 independent firms, and the controls are set out in the risk management framework. Before you pick any provider, run it through vault provider due diligence.

Frequently asked questions

Should an exchange build Earn in-house or use a vault provider?

Build in-house if you run a treasury desk at scale and want the whole spread. A vault provider moves contracts, audits, NAV and withdrawals off your roadmap, and Tria went live in two weeks this way.

Who holds customer funds in a white-label Earn product?

The vault contract holds the assets, and each customer holds vault shares. With Upshift the curator can't move depositor funds to an outside wallet, and the vault owner is a multisig.

How much revenue does an exchange keep from Earn?

The exchange keeps the fee it sets on top of the vault's yield, plus any share of vault fees in its distribution agreement. Fees are set per vault and per partner, and no market-wide standard is published.

Can an exchange offer more than one risk level?

Yes. Each band runs as a separate vault with its own disclosures, and a second band can be added to the same SDK integration later.

How long does a white-label Earn launch take?

Tria's SDK integration took two weeks to go live in January 2026. A custom vault built to your own mandate adds time for the strategy setup and diligence.

What happens if a protocol inside a vault is exploited?

Losses hit the vault's share price, which is why caps per protocol and per counterparty matter. Upshift vaults carry no protocol-level smart contract insurance, though cover can be bought from third-party providers.
