A DeFi position is a dependency chain. Identify the network, contracts, administrative controls, oracle, liquidity, token approvals, bridged assets, interface, and exit path. A high yield or completed audit does not remove these dependencies.
At a glance
- Smart-contract audits are evidence of review, not guarantees.
- Oracle inputs have source, timing, aggregation, and governance assumptions.
- Bridged assets depend on additional verification or custody systems.
- Headline yield should be decomposed into fees, emissions, token price exposure, and withdrawal costs.
Step-by-step walkthrough
- Write down the network, protocol, contract addresses, and interface domain.
- Identify upgrade, pause, mint, freeze, multisig, and emergency powers.
- Record oracle providers and what happens when data becomes stale or unavailable.
- Inspect liquidity, withdrawal rules, lockups, incentives, and likely slippage under stress.
- Identify bridged or wrapped assets and the system backing each representation.
- Find audits, bug bounties, incident history, and a public emergency communication channel.
- Define how to revoke approvals and exit if the primary interface is unavailable.
A 20% advertised yield
The number becomes meaningful only after its components and dependencies are identified.
| Signal | What it can mean | Important caveat |
|---|---|---|
| 5% trading fees | Depends on volume and provider share. | Volume and pool share can change. |
| 15% token incentives | Paid through new or treasury tokens. | Token price and emissions may fall. |
| Audited contracts | A defined review occurred. | Economic, oracle, bridge, and new-code risks remain. |
Common mistakes and edge cases
- Treating total value locked as a safety score.
- Assuming “non-custodial” means no governance or key-holder risk.
- Ignoring token approvals, bridge dependencies, or oracle failure modes.
- Comparing yields without matching time periods, token units, and exit costs.
