What a $15 scope-limited DeFi fee review actually looks like

Fictional decision

A hypothetical user considers moving $10,000 of stablecoins from a position assumed to earn 3.0% per year to a candidate with 4.5% base yield and a 1.0% reward-token incentive. We model realizing only 50% of that token incentive (so candidate effective APY = 5.0%). The move costs an estimated $24 including gas, swap fees, exit costs and 15 basis points of slippage. Two days produce no new yield.

Stress the reward dependence

If the reward token stops paying completely, the candidate APY falls to its base 4.5%. In that hypothesis, 90-day incremental income shrinks to roughly +$10.52. This is not a worst-case loss: depegging, adverse token price changes, failed bridge settlements, liquidations or vault loss may exceed the entire deposit.

Primary-source diligence needed before any decision

1. Obtain dated protocol URLs explaining how each APY is derived, whether it is variable, and whether reward tokens vest, decay or stop at a known date.
2. Read official vault deposit/redemption conditions, lock duration, queue limits, cooldown and all withdrawal penalties.
3. Record date-stamped actual route quotes for gas, swap price impact, bridge fees and how long the transfer may be pending; re-quote before any transaction.
4. Review chain IDs, canonical token contracts, bridge design, oracle/collateral/liquidation dependencies, and documented audits; an audit is not a guarantee.
5. Check stablecoin exposure including redemption or bank settlement terms, potential depegs, currency FX risk and jurisdiction-specific tax records.

What the optional 15 USDC scoped review provides

After agreeing on a specific non-sensitive one-pair question in writing, the deliverable is a compact one-page evidence memo: an assumptions table, dated primary-source links supplied or openly available, a cross-checked cost and break-even scenario, unverified/unknown data flagged clearly, and a short list of questions to ask the protocol before depositing. It is not investment selection, personal financial advice, a security audit or an APY guarantee. Payment is arranged only after the real owner accepts the scope; this free sample is not an order.
