DefiLlama review

Every number can be traced

DefiLlama's adapters are open source, which means any TVL figure it publishes can be followed back to the contract calls that produce it. When you disagree with a number, you can read the code that made it and file a fix. No commercial provider in this sector offers that, and it is why DefiLlama's figures became the ones everyone else quotes.

It documents its own weaknesses

Double-counting rules — staked derivatives, treasury holdings, cross-chain wrappers — are documented and toggleable in the interface, so you can see how a headline changes under different assumptions. A provider that shows you the assumptions is providing a measurement; one that shows you a single figure is providing an opinion.

Free, in a way that shapes the sector

Core data and the API are free with no paywall on the headline numbers and no premium tier gating them, and the data downloads without an account. The one real caveat is maintenance: adapters are community-contributed and vary in freshness, so a specific protocol's figure may lag while the majors stay current.

What it does not do

There is no wallet labelling, no entity attribution and no attempt to tell you who is behind a flow. It measures protocols, not people, and that boundary is part of why the data stays trustworthy — it publishes what can be derived from contracts rather than what requires judgement.

Who it is for

Everyone, at some point: it is the sector's default reference for TVL, fees, revenue, yields and chain comparisons, and none of that sits behind a paywall.
