What Rails Covers

Compound V3 on Base is a separate deployment from Compound V3 on Ethereum — five Comet markets of its own, with their own collateral rosters, their own risk parameters and their own accounts — so the two are separate explorers rather than a switch inside one. A Comet market is single-base and multi-collateral: one asset is both the lend and the borrow side, every collateral asset backs borrowing of that base alone, and nothing is cross-collateralised between markets. So a wallet has a separate standing and a separate liquidation line in each market it touches, and this explorer never states a combined one. It also never totals across them, because they do not all measure in the same unit: four quote in dollars and cWETHv3 quotes in ETH, which is the unit each market's own oracle answers in. That unit is a fact about the market rather than about its base asset — cAEROv3's base is the volatile asset and it still quotes in dollars. What sets this explorer apart from Compound V3 Ethereum's is where each figure comes from, and in one respect it reaches further. The Ethereum listing is a replay of an indexed event stream; this one is not a replay at all: every (market, account) pair that ever held a position is found from the five Comets' own events, and each account's base and collateral are read from that Comet at the block its row names and read again after any event — risk is read live on the position page — so a listing figure is a fact the chain stated rather than a reconstruction — and the page states its own completeness, how far the history walk and the sweep have each got, rather than letting a partial roster look whole. Opening a row answers the whole wallet at once — every market in the roster asked about the account, and the address's history read from the Base box's capture of every Comet's events from the earliest market's first block (a live sweep of their logs stands in when the capture cannot answer), so the history reaches each position's genesis rather than a recent window, and the Lifetime flows panel can state every flow at Comet's oracle price at its block and the interest inside the debt. Comet has no borrow or repay event — a withdrawal past the balance is the borrow and a supply against a negative balance is the repayment — so those flows are read off the running balance's zero crossings, as the protocol itself defines them. A timeline states underneath itself anything its history is missing. Two facts of this deployment are stated: one market's borrows stand above its supplies, which is the borrow index outrunning the supply index by the spread between the two rates rather than a shortfall, and four different proxies on Base answer to the name cUSDCv3, only one of which Compound governance deployed — so the roster here is settled from the Configurator's own deployment log rather than from a name.

Moonwell is a Compound v2 fork, and Base is where it actually runs: twenty-one markets against Ethereum's four, and tens of millions supplied against a few million. The two are separate deployments with separate contracts, so they are separate explorers — a wallet's position on Base says nothing about its position on Ethereum. What sets this explorer apart from Moonwell Ethereum's is where each figure comes from. The Ethereum listing is a replay of an indexed event stream; this one is not a replay at all. Every wallet that ever held a position is found from the twenty-one markets' own events on the Base box — with a routed mint or redeem resolved to its real owner through the same-transaction transfer leg, the way the Ethereum index does it — and each account's balances, debt, exchange rates and dollar values are read from the mTokens, the Comptroller and its own oracle at the block its row names and read again after any event; risk is read live on the position page. So a listing figure here is a fact the chain stated at a block the row names, never a reconstruction, and the page states its own completeness — how far the history walk and the sweep have each got — rather than letting a partial roster look whole. Opening a position reads that one wallet's whole history from the Base box's capture of the twenty-one markets' events, from the Comptroller's first block. That is why the timeline reaches the position's genesis rather than a recent window, why the Lifetime flows panel can state every flow at Moonwell's oracle price at its block and the interest on both sides, and why the account surface can say which of a wallet's supplies are actually entered as collateral (minting alone does not enter a market, and an un-entered supply backs nothing) beside the Comptroller's own verdict on how far it sits from liquidation. When the capture cannot answer, Rails sweeps the chain instead: a Compound v2 market indexes nothing on its own events, so the sweep anchors on the reward distributor — the one contract on this deployment that names the account on every action — and reads each transaction it names. A timeline states underneath itself anything its history is missing — on the few accounts too large to send whole, from which date onward it is drawn. Two facts of this deployment are stated rather than smoothed over: two markets carry a supply cap BELOW what they already hold, which is governance closing them to new deposits rather than a ceiling being breached, and two different markets both answer to the mToken symbol "mUSDC" (the bridged and the native USDC), so only an address identifies a market here. Since 4 September 2026 every event block the Base box captures is also read for the Comptroller's own oracle — every market's price and exchange rate, the incentive and the close factor, all at that block and stored — so a liquidation card values both legs at the prices the seizure was computed with and states the premium against the incentive read from the same block, and an ordinary row names its market's price at its own block. The newest blocks are priced within minutes and every liquidation block is priced; older ordinary rows are priced as the historic walk reaches them and render token-only until then, and a position holding such rows says so above its timeline, with the date the walk is expected to reach them. Since 4 September 2026 a position that held a market’s shares across a step in that market’s own exchange rate also carries a market note on its timeline — a receipted row rather than an event, never counted in any total, placed between the two of the account’s own events that bracket the step, stating the rate at each end and what the position’s own shares were worth at each. The rate is derived rather than read: every Mint and Redeem in a market emits the underlying amount and the mTokens it was exchanged for, and their quotient is the market’s rate at that block, so this needs no oracle. A step is stated only where the change over the whole market’s series exceeds ten times the interest the market could have accrued over the same seconds — across the twenty-one markets’ entire history three such steps exist. A live note sits above the newest row for any entered market the account still holds: the same market’s own exchange rate read live at the chain head, against the account’s own newest Mint or Redeem in it, holding the account’s CURRENT holding fixed and moving only the rate — shown whatever the move, because nothing having changed since is itself the fact it states.

Seamless is an Aave V3 fork on Base, verified as one by interface rather than by reputation: its Pool answers the identical account, reserve and configuration calls, which is what lets the same reader serve it. So the model is Aave's — one Pool, one cross-collateralised account per wallet, one health factor — and everything the Aave V3 Base explorer says about reading risk off each reserve's own configuration word holds here too. What is different is that this market is closed. All eighteen reserves were frozen in a single block on 15 April 2025, which is one governance action, and the freeze was read off the chain by binary search over the frozen bit. A frozen reserve still accrues interest, still liquidates, and still lets a holder repay and withdraw; what it will not accept is a new supply or a new borrow. So every rate and threshold this explorer shows is live and enforced, and none of it is an invitation — which is why the surfaces say so. The listing here is not a replay: every account that ever touched the Pool is found from the Pool's own events, and each account's balances and dollar values are read from the Pool, its reserve tokens and its oracle at the block its row names and read again after any event — risk is read live on the position page — so a listing figure is a fact the chain stated rather than a reconstruction — and the page states on its face how far the history walk and the sweep have each got, rather than letting a partial roster look whole. The census has an unusual shape here, and it is worth naming: because the Pool is frozen, the set of accounts that can ever hold a position on it is closed and can only shrink, so once taken it stays complete rather than going stale. That is true of no other explorer on this roster. Opening a position reads that one wallet's whole history from the Base box's capture of this Pool's events, from its first block (a live sweep of the Pool's own logs stands in when the capture cannot answer), which is why the timeline reaches the position's genesis. Since 4 September 2026 every event block the Base box captures is also read for the Pool's own oracle — every reserve's price and liquidation bonus at that block, stored — so a liquidation card served from the index values both legs at the prices the seizure was computed with and states the premium against the bonus read from the same block, with the protocol's share of that bonus read at the same block too (0 on most reserves; 10% on cbBTC, EURC and weETH today), and an ordinary row names its reserve's price at its own block. The historic walk has reached the Pool's first event, so every row names its reserve's price at its own block.
