Crypto tools that cover DeFi

Three claims that a reader hears as one

Thirty-two cards say they cover DeFi. The reason this page exists is not the thirty-two — it is the three separate things that phrase can mean, and the cards that have one without the others.

coverage.asset_classes: defi says the card reports protocol positions: pools, lending markets, staking, yield. That is the selector for this page.

coverage.venues: dex says where a price came from — an automated market maker rather than an exchange order book. Twenty-six cards in the catalogue claim that and do not claim DeFi. A CCXT connector routing an order through a DEX is not reporting anything about the protocol it routed through; neither is a bot, a charting platform, or a tick archive that happens to record swap events.

capabilities.onchain_data says the product reads chains at all. Eight cards have it without DeFi — a liquidation dashboard, a holder-graph tool, a terminal that shows a wallet balance. And four cards on this page have DeFi without it: CoinAPI, Hummingbot, Gunbot and Velo touch DeFi assets by trading them, not by indexing them.

One card on this page claims DeFi and not DEX — growthepie, which measures Ethereum layer twos rather than trading on them. That is the shape of the whole distinction in a single row.

What is actually on the page

Fifteen are on-chain analytics platforms and eight are market-data APIs; the remaining nine are terminals, charting tools, bots and one backtester. Twenty-three have a free tier, the highest share of any shelf here, and three are open source. That combination is particular to this corner of the market: the underlying data is public, so what a vendor sells is the indexing, the decoding, the history and the query — never access to the numbers themselves.

They split cleanly into two kinds of product, and choosing between the kinds matters more than choosing between vendors inside one.

Curated metric sets. DefiLlama is the type specimen: somebody has already decided what TVL, fees, revenue and earnings mean, written the rules down, and applied them uniformly — 8,308 protocols across 468 chains in 102 categories on 19 September 2026. What you buy is comparability. What you give up is everything outside the list: no SQL, no custom aggregation, and adding a metric means writing an adapter and opening a pull request. Token Terminal and Artemis work the same way against different definitions.

Query engines. Dune, Allium, Bitquery and Footprint Analytics hand you the decoded tables and let you define the metric yourself. The cost is that you now own the definition, including the parts you did not think about.

And pool screeners, which are a third thing wearing the same word. DEX Screener, DEXTools and GeckoTerminal list live pairs — 228 networks and 1,978 DEXes on the last of those — and answer "what is trading right now", not "what is this protocol worth".

Where the free path stops

Later than anywhere else on this site, and then abruptly. DefiLlama's site and public API cost nothing and need no account; Pro is 49 dollars a month; the API tier is 300 and is where the per-minute limit, the unlock data and the MCP server live; hourly history, raw database access and TVL broken down by token address are enterprise. GeckoTerminal is free to read and free to query slowly. Dune puts the API on every plan including the free one, which is unusual enough to be the reason to pick it.

Twenty-two of the thirty-two cards carry at least one tier with no published number, so the priced on request shelf overlaps this one heavily. And two of the screeners are paid for in a way that is not a subscription at all: DEX Screener by token promotion, DEXTools by tiers gated on holding its own token. What that costs, and why it cannot be compared with a monthly fee, is a token threshold is not a price.

The two things to check before trusting a number

The definition. "Active addresses" can mean senders, receivers or either. TVL may or may not net out the same collateral counted in two protocols. A vendor that publishes its methodology is making a claim you can check; one that does not is asking for trust, and the numbers will differ.

The chain list, on the card rather than on the site. Trading Strategy is EVM-only — no Solana, no Bitcoin — and says so plainly, which is a partial picture honestly labelled. Footprint Analytics covers neither Solana, Bitcoin nor Tron while its homepage logo strip shows two of them. Whether a chain you care about is a first-class citizen or a line in a coverage table is not something the coverage table distinguishes; the Solana shelf is the same problem at chain scale.
