Live on-chain data for Mantle (chain-id 5000), a modular EVM Layer 2 with the MNT native gas token. Read the chain status — chain id, latest block number, current gas price, node client version and sync state — fetch any block by number (or the latest) with its hash, parent hash, timestamp, transaction count, gas used and limit, base fee and proposer, read the current gas price and max priority fee in both wei and gwei, and look up any account address for its MNT balance (in wei and whole MNT) and transaction nonce. Addresses use the standard 0x EVM hex form. A short protective cache keeps responses fast while staying within a few seconds of the chain. Distinct from other Layer-1, Layer-2 and Cosmos-chain APIs on the marketplace: this surfaces the Mantle network specifically.

Live on-chain data for Fraxtal (chain-id 252), an Optimistic-rollup EVM Layer 2 from Frax Finance that uses frxETH (Frax Ether) as its gas token. Read the chain status — chain id, latest block number, current gas price, node client version and sync state — fetch any block by number (or the latest) with its hash, parent hash, timestamp, transaction count, gas used and limit, base fee and proposer, read the current gas price and max priority fee in both wei and gwei, and look up any account address for its frxETH balance (in wei and whole frxETH) and transaction nonce. Addresses use the standard 0x EVM hex form. A short protective cache keeps responses fast while staying within a few seconds of the chain. Distinct from the Frax Finance protocol pools/yields feed and from other Layer-1, Layer-2 and Cosmos-chain APIs on the marketplace: this surfaces the Fraxtal chain itself.

Addresses use the standard 0x EVM hex form. A short protective cache keeps responses fast while staying within a few seconds of the chain. Distinct from other Layer-1, Layer-2 and Cosmos-chain APIs on the marketplace: this surfaces the Abstract ZK network specifically.

Live on-chain data for Sonic (chain-id 146), a high-performance EVM-compatible Layer 1 (the network formerly known as Fantom) with the S gas token. Read the chain status — chain id, latest block number, current gas price, node client version and sync state — fetch any block by number (or the latest) with its hash, parent hash, timestamp, transaction count, gas used and limit, base fee and proposer, read the current gas price and max priority fee in both wei and gwei, and look up any account address for its S balance (in wei and whole S) and transaction nonce. Addresses use the standard 0x EVM hex form. A short protective cache keeps responses fast while staying within a few seconds of the chain. Distinct from other Layer-1, Cosmos and Move-chain APIs on the marketplace: this surfaces the Sonic EVM network specifically.

Der Ethereum-Blob-Datenverfügbarkeits-Gebührenmarkt, von dem jedes Layer-2-Rollup lebt und stirbt, live aus dem öffentlichen Blobscan-Datensatz, kein API-Key. Seit dem Dencun-Upgrade (EIP-4844, Proto-Danksharding) posten Rollups ihre komprimierten Transaktionsdaten nicht mehr als teures Calldata – sie posten sie als Blobs, große temporäre Datenpakete, die in ihrem eigenen unabhängigen Gebührenmarkt bepreist werden (dem Blob-Gas-Markt mit seiner eigenen Basisgebühr, die steigt, wenn Blöcke voller Blobs sind, und fällt, wenn sie es nicht sind). Blob-Space ist jetzt der mit Abstand größte Kostenfaktor für fast jedes Rollup, daher sind die Blob-Basisgebühr und wie viel Blob-Space jedes Rollup verbraucht die Kernökonomie des gesamten Layer-2-Ökosystems – wenn die Blob-Nachfrage steigt, steigen die Kosten jedes Rollups (und letztlich seine Nutzergebühren) gemeinsam. Der Netzwerk-Endpunkt gibt den Live-Zustand des Blob-Gebührenmarktes zurück: die aktuelle Blob-Basisgebühr, den Durchschnitt über die letzten Blöcke, die durchschnittlichen Blobs pro Block im Vergleich zum Protokollziel und -maximum, die resultierende Auslastung, das überschüssige Blob-Gas, das die Gebühr antreibt, und die pro Block verbrannte Datenverfügbarkeitsgebühr. Der Rollups-Endpunkt ist die Schlüsselansicht – er ordnet die Layer-2-Rollups danach, wie viel Blob-Space sie gerade verbrauchen (Base, Arbitrum, Optimism, World, Taiko und der Rest), jeweils mit ihrer Blob-Anzahl, verbrauchtem Blob-Gas, Anteil am gesamten Blob-Space und der in ETH gezahlten Datenverfügbarkeitsgebühr. Der Blocks-Endpunkt listet die letzten Blöcke mit ihrer Blob-Anzahl, Blob-Basisgebühr und DA-Gebühr auf. Dies ist der Blob-/Datenverfügbarkeits-Gebührenmarkt-Ausschnitt – unterschieden vom Multi-Chain-Ausführungsgas-Orakel (dem EIP-1559-Ausführungsgas-Markt, nicht dem separaten Blob-Gas-Markt), dem ETH-Angebot/Verbrauch-Feed (der eine einzelne Blob-Basisgebührenzahl meldet, aber nicht die Blob-Space-Auslastung oder welche Rollups sie verbrauchen) und den On-Chain- und TVL-Feeds. Gebühren sind in Gwei und ETH; Zahlen sind live, pro Block.

Live Ethereum mainnet on-chain data as an API, built on the open Blockscout explorer — a different layer from market-price feeds. Pull network stats (total blocks and transactions, ETH price, market cap and live gas usage), a gas oracle with slow, average and fast prices in gwei, the most recent blocks and full block detail by height or hash. Look up any address for its ETH balance, ENS name and contract status, any transaction by hash for its value, fee, status, sender and receiver, and any ERC-20 token by contract for its name, symbol, decimals, holders and USD exchange rate. A universal search resolves addresses, tokens, blocks and transactions in one call. Real on-chain data, no key needed upstream. Ideal for wallets, block explorers, gas trackers, DeFi dashboards and crypto analytics.
