The block explorer
engineers keep open.
Genesis indexes every block, every transaction, every contract — with finality receipts, source verification, and a query API built for production, not the browser tab.
Four panes,
one archive.
Tx stream, holdings, validator pulse, gas chart. All sit on the same archive node — query any one, render any layout.
Four primitives.
One archive.
Any block, any chain, sub-150ms.
Genesis serves block headers, transaction lists, and event logs from a horizontally-sharded archive of every EVM chain we support. The cold path returns in 142 ms, the warm path in 8.
Source, by hash. No upload.
Submit a contract address — Genesis returns the verified Solidity source, ABI, constructor args, and the libraries it depends on. We index every Etherscan-verified contract on push.
Read every internal call.
Get the full call tree for any transaction — internal value transfers, delegate-calls, reverted branches. Built on a custom geth fork with zero-cost trace recording.
Confidence in every response.
Each lookup returns the canonical block hash, the depth, and a reorg probability. Build production systems against finality, not against the latest tip.
On-chain index
vs CEX panel.
Five places where a real archive node beats a centralized panel. The data is public — we just made it queryable in production.
“Genesis is the only explorer I have not closed in three weeks. The trace API replaced a 600-line script we were using for incident response.”
Pricing
by request.
Pay for the queries that hit the archive. No seat fees, no project fees, no browsing fees. Predictable enough for a budget line.

Mechanics & custody.
Coverage, freshness, finality, custody — every question your protocol team and your auditor will ask.
Ethereum mainnet, Arbitrum One, Optimism, Base, Polygon zkEVM, and Linea — full archive on each. Custom chains are available on the Enterprise tier.
Protocol upgrades.
Polygon zkEVM is now in full-archive mode — block 1 to tip.
Trace API now exposes delegate-call return data without re-running the transaction.
Verified-source index now ingests from Sourcify in addition to Etherscan.
Finality receipts are now stable — depth + canonical hash on every response.
The archive is open.

Block 1 to tip, every chain we support, every contract we have indexed. No seat fees. Just the data, signed and dated.
