#on-chain

The on-chain prices that DeFi actually runs on, read live and keyless straight from Chainlink's price-feed contracts on Ethereum. Chainlink is the dominant oracle: a decentralised network writes each price on-chain and refreshes it on a heartbeat or when it moves past a deviation threshold, and thousands of lending, perpetual and stablecoin protocols read that exact number to value collateral and trigger liquidations. What matters is not just the price but whether the feed is fresh — a stale Chainlink feed is how DeFi protocols break — and that on-chain freshness is exactly what this exposes. The feeds endpoint lists every tracked Chainlink feed (crypto, stablecoins and FX) with its current on-chain answer, how many seconds ago it last updated and whether it is fresh. The feed endpoint returns one pair's full detail by name, including the round id, the update timestamp and the feed contract address. The health endpoint is the oracle-monitoring view: how many feeds are fresh versus stale, the stalest feed and the average update age — the on-chain reliability picture that a plain price API can't give you. Each price is read from the feed's latestRoundData and scaled by the feed's own on-chain decimals (USD feeds use 8); the update time is the contract's updatedAt. This is the Chainlink on-chain-oracle cut — distinct from the off-chain oracle-price APIs (which serve a price but not the on-chain feed's round and freshness) and from the exchange price feeds. Prices are in the feed's quote unit (USD here); times are UTC. No key, nothing stored beyond a short cache.

Where dollar stablecoin liquidity actually lives, read live and keyless from each blockchain. USDC and USDT are issued natively on many chains, and the split between them is one of the most-watched signals in the layer-2 wars: Ethereum mainnet still holds the bulk, but Base, Arbitrum and the other rollups have been pulling stablecoin supply across as activity migrates. This API reads the native USDC and USDT supply directly from the token contract on each chain — Ethereum, Base, Arbitrum, Optimism, Polygon and Avalanche — not a single chain and not an aggregator, so you see the real on-chain distribution. The stablecoin endpoint takes a symbol (USDC or USDT) and returns its supply on every tracked chain, ranked, each with its share of that stablecoin and the Ethereum-versus-rollup split. The chains endpoint ranks the chains by their total native stablecoin liquidity (USDC and USDT together) — which chain hosts the most dollars. The summary endpoint is the top-down view: total USDC, total USDT, the combined total, the USDT-to-USDC ratio, and Ethereum's dominance versus the share that has moved to the rollups. Because USDC and USDT are dollar-pegged and read at the token's own on-chain decimals (read live from each contract, never assumed), the supply equals the dollars of stablecoin on that chain; only natively-issued supply is counted (bridged and peg tokens are excluded). This is the stablecoin chain-distribution cut — distinct from the single-chain token feeds, the generic stablecoin-supply aggregators and the price feeds: it is specifically the cross-chain liquidity map. Amounts are in US dollars. No key, nothing stored beyond a short cache.

The Bitcoin cycle-timing valuation models that tell you whether BTC is historically cheap or expensive right now, computed live and keyless from price (Yahoo Finance daily closes) and on-chain data (the public blockchain.com charts feed). These are not raw time series and not a price feed — they are the derived indicators that on-chain analysts and cycle traders watch to judge where Bitcoin sits between deep value and euphoria. The mayer endpoint returns the Mayer Multiple — price divided by its 200-day moving average — the simplest and most durable over/undervaluation gauge (buying under ~1 and trimming over ~2.4 has historically timed cycles well). The puell endpoint returns the Puell Multiple — daily miner revenue divided by its 365-day average — a miner-side gauge that marks capitulation bottoms (under ~0.5) and tops (over ~4). The nvt endpoint returns the NVT ratio — market cap divided by the 90-day average of on-chain transaction value — Bitcoin's answer to a price/earnings ratio, where a high reading means price is rich relative to the value actually settling on-chain. The s2f endpoint returns the Stock-to-Flow scarcity ratio — circulating supply divided by the realised annual issuance (the flow measured empirically from the supply actually minted over the last 365 days); the S2F price model derived from it is included but clearly flagged as controversial and historically over-optimistic (the response also reports how far the model sits above the actual price). The summary endpoint puts all four side by side with an aggregate cycle read. This is the valuation-model / cycle-indicator cut — distinct from the raw Bitcoin on-chain time-series feeds (which report hashrate, miner revenue and transaction counts but not the derived ratios), the network-security feed (difficulty, hashrate, halving), the block-explorer feed and the crypto-macro correlation feed. Ratios are unitless; model and actual prices are in USD. No key, nothing stored beyond a short cache.

Bitcoin's network-security and mining-economics layer, live and keyless, powered by mempool.space — hashrate, mining difficulty, the difficulty-adjustment countdown, the halving countdown and per-window block-reward economics. These are the numbers that describe how hard Bitcoin is to mine and how secure the chain is, not a price and not a block explorer. The difficulty endpoint is the flagship: the current mining difficulty plus the live adjustment countdown — how far through the current 2016-block epoch we are, the projected size of the next adjustment (Bitcoin retargets every two weeks so blocks stay ~10 minutes apart), the blocks remaining to the retarget, the estimated retarget date and the realised average block time. The hashrate endpoint returns the current network hashrate in EH/s plus a historical hashrate-and-difficulty timeseries over a chosen window (1m to all). The halving endpoint is the countdown to the next block-subsidy halving — the current block height, the current subsidy in BTC, the next halving block and how many blocks and days remain. The rewards endpoint returns block-reward economics over a recent window: the total miner reward, the fee share, and the per-block averages, all in BTC. This is the Bitcoin difficulty / hashrate / halving cut — distinct from the Bitcoin block-explorer feed (mempool, fees, blocks, addresses, transactions), the mining-pool-distribution feed (who finds the blocks and how centralised), and the multi-coin mining-profitability feed. Hashrate in EH/s, difficulty raw and in trillions, rewards in BTC, times in UTC. No key, nothing stored.

Who secures Solana and how decentralised it is, read straight from a public Solana RPC node. Solana is proof-of-stake: validators vote with the SOL delegated to them, and the distribution of that stake decides both rewards and security. The validators endpoint ranks validators by activated stake, with each one's stake in SOL, its share of total stake, its commission and whether it is delinquent (currently failing to vote). The staking endpoint returns the staking economics — total active stake, the circulating and total SOL supply, the percentage of supply that is staked, the current inflation rate broken into its total, validator and foundation components, and the current epoch with its progress. The centralization endpoint computes the stake-centralisation metrics — the Nakamoto coefficient (the fewest validators that together control more than one third of the stake, the amount that could halt the chain under Byzantine-fault-tolerant consensus), the top-10 and top-20 stake share, and the Herfindahl concentration index. This is the Solana validator, staking and decentralisation data-cut, distinct from the Solana on-chain account/transaction API and the other staking and exchange APIs in the catalogue. Live from a public RPC, no key on the upstream, nothing stored.

Who actually mines Bitcoin's blocks, served from the public blockchain.com pools feed. The distribution endpoint ranks the mining pools by the blocks they found over a window (24 hours to 10 days), with each pool's share of blocks and its estimated share of the network hash rate (in EH/s). The centralization endpoint turns that into mining-decentralisation metrics — the top pool's share, the top-3 and top-5 share, the Nakamoto coefficient (the fewest pools that together control more than half of the attributed blocks, a headline measure of how centralised mining is), the Herfindahl concentration index, and the share of blocks not attributed to a known pool. The pool endpoint looks up a single pool's blocks, share, rank and estimated hash rate. This is the mining-pool and hash-rate-distribution / centralisation data-cut — distinct from the mempool-snapshot, the aggregate on-chain-metrics and the price-feed APIs in the catalogue. Estimated per-pool hash rate = block share times network hash rate. Live, no key on the upstream, nothing stored.

The long-run on-chain economics of Bitcoin as time series, served from the public blockchain.com charts feed. Where snapshot APIs report the chain state right now, this is the history: how the hash rate, mining difficulty, miners' revenue, daily transaction count, transaction fees, market price, market capitalisation, circulating supply, mempool size, average block size, estimated on-chain transaction volume, daily unique addresses, UTXO count and median confirmation time have moved over months and years. The metric endpoint returns one metric's full daily time series over a chosen window (30 days to all-time) with summary statistics — first, last, change, percent change, minimum, maximum and average. The latest endpoint returns a metric's current value with its change versus the previous reading and versus 30 days ago. The metrics endpoint lists every available metric with its unit and category. This is the historical and charting view of Bitcoin's network economics — distinct from the live mempool-snapshot, the multi-chain network-stats and the price-feed APIs in the catalogue. Live, no key on the upstream, nothing stored.

Live economic-activity metrics for Ethereum Layer-2 rollups — Arbitrum, Base, Optimism, zkSync, Linea, Scroll, Polygon and more — powered by the public growthepie.xyz feed, no key, nothing stored. This is the L2 fundamentals cut: not a single chain's block or gas data, but how much each rollup is actually used and what it earns. The chains endpoint lists the tracked rollups. The chain endpoint returns one rollup's latest metrics: daily active addresses, transaction count, fees paid, on-chain profit (the fees it keeps after paying Ethereum to post its data), median transaction cost, stablecoin supply, total value locked, market cap and fully-diluted valuation. The metric endpoint ranks every rollup by a single metric, so you can see at a glance which L2 leads on users, fees or profit and how the scaling race is shifting. Track the real adoption and economics of the rollup ecosystem as live JSON. This is the L2 activity / economics cut — distinct from the per-chain on-chain (block and gas) APIs and the TVL-only APIs in the catalogue.

Live on-chain crypto options trading volume — the decentralized options market where protocols like Derive, Aevo, Premia, Ithaca and Rysk let users trade calls and puts on-chain, powered by the public DeFiLlama options feed, no key, nothing stored. This is distinct from a centralized options exchange order book: it measures the volume actually flowing through on-chain options venues. The overview endpoint returns the whole on-chain options market's volume over the last 24 hours, 7 days and 30 days plus every protocol ranked by what it trades, measured as notional (contract face value, the default) or premium (what option buyers actually paid). The protocol endpoint returns a single protocol's notional and premium volume side by side across 24h / 7d / 30d / all-time. The chain endpoint returns the options volume and top venues for one blockchain. See which on-chain options venue leads and how DeFi options flow shifts. This is the on-chain options-volume cut of DeFi — distinct from the centralized options-chain, spot-DEX, swap-aggregator, fees and perpetual APIs in the catalogue.

Live Ethereum monetary-policy data — the total ETH supply, how much of it is being created versus destroyed, and the EIP-1559 fee burn that can make ether deflationary (the "ultrasound money" thesis), powered by the public ultrasound.money feed, no key, nothing stored. The supply endpoint returns the current circulating ETH supply and its net change over the last 5 minutes, hour, day, week and month — a negative change means more ETH was burned than issued, i.e. net deflation. The burn endpoint returns the ETH destroyed by the base-fee burn over each window in both ETH and USD, the live burn rate in ETH per minute and the current deflationary streak. The basefee endpoint returns the current base fee per gas, the blob base fee and the ETH price. The leaderboard endpoint ranks the apps and contracts burning the most ETH right now. Track ETH issuance, the burn and whether ether is deflating as live JSON. This is the ETH supply / issuance / burn cut — distinct from the gas-fee, on-chain and price APIs in the catalogue.

Live trading volume routed through DeFi DEX aggregators — Jupiter, 1inch, CowSwap, Paraswap, OKX Swap, KyberSwap and more — powered by the public DeFiLlama aggregators feed, no key, nothing stored. Aggregators don't hold liquidity themselves: they split each trade across many underlying decentralized exchanges to get the best price, so their volume is the single best measure of where real swap flow actually routes. The overview endpoint returns total aggregator volume over the last 24 hours, 7 days and 30 days plus every aggregator ranked by what it routes, with its category and the chains it covers. The aggregator endpoint returns a single aggregator's volume across 24h / 7d / 30d / all-time. The chain endpoint returns aggregator volume and the top routers for one blockchain (Solana, Ethereum, Base). See which router dominates each chain and how swap flow shifts. This is the swap-routing / aggregator-volume cut of DeFi — distinct from the spot-DEX-volume, fees-and-revenue, TVL and exchange-ticker APIs in the catalogue.

A live database of cryptocurrency and DeFi hacks, exploits and thefts — every major on-chain theft on record, powered by the public DeFiLlama hacks dataset, no key, nothing stored. Each incident carries the victim, the amount stolen in US dollars, the date, the attack technique (flash-loan oracle manipulation, reentrancy, private-key compromise, access-control exploit and more), a higher-level classification, the chain or chains involved, the target type (DeFi protocol, centralized exchange, bridge, wallet, token) and how much, if any, was later returned. The hacks endpoint returns the incident list newest-first, filterable by chain, technique, target type, classification, year and minimum loss. The biggest endpoint ranks the largest exploits of all time by dollars stolen — from the multi-billion-dollar bridge and exchange breaches down. The stats endpoint aggregates the whole dataset: total stolen, incident count, funds returned, and breakdowns by attack technique, chain, target type and year. This is the crypto-security and exploit-history cut — risk and post-mortem data distinct from the price, market, TVL, fees and on-chain APIs in the catalogue.

Live data on the fees users pay to DeFi protocols and the revenue those protocols actually keep — the "which protocols earn money" view, a different layer from Total Value Locked. TVL is what is deposited; fees are what users pay to use a protocol; revenue is the slice the protocol or its token-holders retain. Powered by the public DeFiLlama fees feed, no key, nothing stored. The overview endpoint returns the whole-DeFi fee (or revenue) total for the last 24 hours, 7 days and 30 days plus every protocol ranked by what it earns, with its category and chains. The protocol endpoint returns a single protocol's fee and revenue figures side by side across 24h / 7d / 30d / all-time (e.g. Aave, Uniswap, Lido). The chain endpoint returns the fee or revenue total and top-earning protocols for one blockchain (Ethereum, Solana, Base). Switch any list between gross fees and retained revenue with a single metric parameter. This is the fees-and-revenue cut of DeFi — distinct from the TVL, DEX-volume, exchange-ticker and coin-markets APIs in the catalogue.

Symbols are Hive-Engine tokens such as LEO, BEE, SWAP.HIVE or SPS; prices and market volume are denominated in HIVE, the base-chain coin. This is the token-sidechain / on-chain-DEX view — per-token supply, holders and an internal order-book market — distinct from the single-venue exchange tickers, the cross-exchange coin-markets and the base-chain on-chain APIs in the catalogue. Live and read straight from a public Hive-Engine RPC node — nothing stored.
