What Matters: A stablecoin targets a price; a yield product adds another set of exposures. Before comparing advertised rates, identify who pays the return, who controls the assets, what you receive at settlement and how you can exit. This update replaces the original 2025 guide’s savings-account comparisons and broad safety claims with a product-by-product research framework.
Start with the source of the return
Holding a dollar-targeting token and subscribing to a yield strategy are different decisions. The issuer, network and token contract are one layer. A lender, exchange, vault or structured product adds another. Returns can come from borrower interest, trading fees, token incentives or option premiums. Those cash flows have different failure conditions and should not be ranked by one headline APY.
| Mechanism | Possible source of receipts | Question before comparing |
|---|---|---|
| Custodial lending or earn programme | Interest or revenue allocated by the provider under its terms. | Who owes you the assets, where can they deploy them, and can withdrawals be suspended? |
| On-chain lending | Borrowers pay interest through a protocol. | Which pool, available liquidity, collateral rules and administrative controls apply? |
| Liquidity provision | Trading fees and possibly incentive tokens. | Can the pool accumulate a depegged asset, and what remains after fees and price changes? |
| Incentive campaign | A finite token or marketing allocation. | When does the subsidy end, and can rewards actually be sold at the displayed valuation? |
| Structured product | An embedded trading or options exposure. | Can settlement change the asset you hold or crystallise a loss? |
What the linked documentation establishes
Aave’s supply documentation describes rates that change with pool utilisation and governance parameters. Its withdrawal documentation says withdrawals depend on available pool liquidity; collateral supporting a borrow position can impose additional constraints. This supports a mechanics explanation, not a current rate quote or a claim that a particular pool is safe.
Circle’s USDC disclosures distinguish digital assets from deposit-protected money. An issuer’s reserve disclosure does not establish that a separate yield provider can repay you. Check the exact token, network, redemption eligibility and intermediary terms rather than assuming a dollar target guarantees a dollar exit.
Dual Investment is not ordinary stablecoin savings
OKX’s Dual Investment FAQ describes returns associated with selling options, settlement in different currencies according to the product conditions, and possible losses on early redemption. It identifies the product as non-principal-protected. The linked regional FAQ may not apply to every customer. DN therefore withdraws the earlier grouping of Dual Investment with simple stablecoin savings. Read the actual order terms and local eligibility before assessing any offer.
Annualised rate is not your holding-period return
APR generally expresses an annual rate before compounding; APY incorporates specified compounding assumptions. Neither tells you that the rate will persist. Promotional tiers, balance caps, reward-token prices and reinvestment costs can change the result.
Fictional example: at a constant 6% simple APR, 1,000 tokens held for 30 days on a 365-day basis generate about 4.93 tokens before costs. Entry and exit costs totalling 8 tokens would leave a net loss of about 3.07 tokens, assuming the principal is fully returned and the token price does not change. This is arithmetic, not a forecast or a provider quote. A depeg, default or different settlement asset requires a separate valuation.
DN stablecoin-yield comparison worksheet
| Record for each product | Evidence to capture |
|---|---|
| Identity and eligibility | Legal entity, jurisdiction, exact product name, token contract and network; date of terms. |
| Return source | Borrower payments, fees, subsidies or option exposure; separate base rate from incentives. |
| Rate assumptions | APR or APY, compounding, tier limits, duration, reward asset and observation time. |
| Asset control | Custodian or contract, upgrade and pause powers, reuse of funds and any bridge exposure. |
| Exit conditions | Notice, queues, available liquidity, minimums, fees, settlement asset and suspension clauses. |
| Stress case | What happens if the token loses its peg, borrowers default, the operator fails or the network stops? |
| Net comparison | Same principal, holding period and valuation currency; costs and taxes shown separately. |
| Unresolved evidence | Record unknowns explicitly. An attractive rate does not fill an evidence gap. |
What changed from the 2025 guide
Removed the “safe protocols” framing, general claims that CeFi provides reliability, the suggestion that mixing CeFi and DeFi maximises safety, and the unsupported Currency.com Treasury-product example. Earlier Binance and OKX product mentions are not a verified current shortlist. No live APY ranking or allocation recommendation is offered. Multiple products can share the same issuer, custodian, collateral or network, so splitting a balance does not necessarily diversify its main risks.
