How to read a DeFi protocol before you deposit
A repeatable checklist for evaluating a decentralized-finance protocol: what the contracts do, who can change them, whether they have been audited, and where the yield actually comes from.
Depositing into a decentralized-finance protocol is not the same as opening an account. There is no support desk that can reverse a mistake, and the code holds the funds. A short, repeatable review before you commit capital removes most avoidable losses.
What does the contract actually do?
Start with the mechanism. Is it a lending market, an automated market maker, a staking wrapper, or a leveraged strategy? Each carries a different risk profile. If you cannot explain in one sentence how the protocol earns and pays out, you are not ready to deposit.
Who can change it?
Find out whether an administrator, multisig, or governance process can upgrade the contracts, pause withdrawals, or move funds. Upgradeable contracts are common and not inherently bad, but they change who you are trusting.
- Is there a timelock on privileged actions?
- How many signers control the multisig, and who are they?
- Can parameters like collateral factors be changed without notice?
Has it been audited, and by whom?
An audit is a snapshot, not a warranty. Read the scope, the date, and whether findings were fixed. A protocol that has run at scale for a long time carries different evidence than a fresh deployment with a single review.
Where does the yield come from?
Sustainable yield has a source: borrowing demand, trading fees, or staking rewards. If the advertised return is high and the source is unclear, treat the gap as risk you have not priced.
