What's covered

Compound V2 is the original cToken deployment, and what stands out about it is how little of it is still in use: it holds around $106M supplied, but only about $12.4M of that is borrowed — under 12% — and two markets, cDAI and cUSDC, carry 94.5% of even that. Eight of its twenty markets have had their collateral factor set to zero, which does not mean a 0% limit; it means the market has been switched off as collateral entirely. The protocol view states that from the markets' own numbers: what each holds in its own token, how much of it is working, the collateral factor it does or doesn't have, and the utilisation its own rate model was tuned to expect. Dollars come from the oracle the Comptroller itself reads, never a price API — with one caveat surfaced rather than hidden: three markets are priced by a constant stored in that oracle with no feed behind it, and the legacy SAI market's constant sits at $14.43 for a token that targets a dollar. Nothing keys on a token symbol, because symbols collide: twenty markets carry eighteen distinct ones, two different markets both answer "cDAI", and the legacy SAI token itself reports the string "DAI" — so only a cToken address identifies a market. The position explorer replays the other side of that stillness: six years of account history — 3.83M events, 26,639 liquidations across 5,864 borrowers, the deepest liquidation record on the roster — proven wei-exact against the chain per market, with each account's live standing read from the Comptroller itself. The present is quiet; the history is why the explorer exists.

Dolomite is a fork of dYdX's Solo Margin, and its grain is the contract's own: a position is an (owner, account number) pair — cross-margined within an account number, isolated across them — so that is what a page is. The core has no borrow action; a negative balance IS debt, and every balance is replayed from the emitted after-state rather than summed from deltas, which is why the whole book proves wei-exact against the contract's own totals with no exclusions. The margin line is the protocol's own arithmetic re-derived exactly: a global 117.65% minimum, per-market premiums applied multiplicatively (WLFI's effective requirement is 150.0%), and an on-chain override that gives ETH-and-LST pair accounts a 111.11% line with premiums skipped — the explorer reads that override per account rather than asserting the ladder as universal. On mainnet Dolomite is in practice WLFI Markets — USD1 and WLFI dominate the book — and the pages state what is there without editorialising. Liquidations exist (122, four named legs each); their valued treatment awaits the oracle-at-block price capture the event stream already carries.

Fluid prices each vault's collateral in its debt token — the vault oracle quotes debt-per-col, the exact quantity the liquidation engine judges, and the protocol has no USD feed. Positions, ratios and liquidation prices are stated in the vault's own token pair rather than converted through a feed the protocol doesn't use. Smart-vault legs hold Fluid DEX pool shares, and the protocol view resolves them into the tokens they are made of — the pool states its own per-share composition, which is a fact about what the shares ARE, not a price. Their liquidations still stay amounts-only: the DEX resolver that answers this at the head has no bytecode at the blocks those liquidations fired in, so nothing on chain can say what a share was made of back then. Liquidations sweep price-band ticks and name no position — the timeline's per-position impacts are the vault's own settlement math read at the boundary blocks, valued at the vault's own oracle read at that same block. Each token-pair vault's realized premium is shown against that vault's own liquidation penalty, read from the block it fired in — a floor the engine guarantees rather than a figure it targets. The two are computed independently, so a sweep landing on its vault's constant is the check that the price is the one the engine used; one landing above it simply cleared on better terms than the minimum, and is shown as it happened.

f(x) socializes funding, rebalances and liquidations across whole ticks without emitting per-position events. The explorer reads exact current state from the pool's own views, reconciles the socialized share explicitly, and replays tick lineage to place each tick rebalance on the timelines it touched — but those amounts are the whole tick's clear: no log states a single position's slice.

Maple's share price is on-chain bookkeeping of an off-chain loan book: the chain proves what the contracts recorded — principal deployed, a posted interest rate, the delegate's impairment marks — not that the loans' custodied collateral (BitGo/Copper/Anchorage/Hex Trust, tri-party) exists. Impairments are a delegate judgment posted on-chain, and withdrawals travel a delegate-operated queue. The explorer shows what a lender actually reaches: the liquid buffer versus the deployed book, live, with the caveat on every receipt.

Each Morpho Blue market measures everything in one token: the loan token it was created with (USDC, for example). Debt is simply a count of that token, and the market's own oracle prices the collateral in it too — the protocol never states a dollar value anywhere. So the explorer doesn't either: showing USD would add an assumption the contracts never make, that the loan token itself is worth $1. Two more limits are the protocol's rather than the roadmap's. Blue keeps no market-wide collateral total — collateral is per-position state, so a market's loan-to-value is a fact about each borrower and not about the market, and there is no such figure to plot; what a market can state about its own shape is how much of what was supplied is currently borrowed. And a market's totals are its last-settled balance rather than its balance now: Blue accrues interest only when someone touches a market, so a market left alone carries the figures from the block it was last touched, and the explorer shows them as they are stored with the current rate beside them. Projecting them forward would be the explorer's arithmetic rather than the protocol's record, and on markets untouched for months at rates the adaptive curve has driven into the hundreds of percent, that arithmetic is the loudest number on the page.
