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.

The dashboard

Four panes,
one archive.

Tx stream, holdings, validator pulse, gas chart. All sit on the same archive node — query any one, render any layout.

Primitives

Four primitives.
One archive.

01
Block lookup

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.

8 ms
warm-cache lookup
02
Contract verification

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.

1.4M
verified contracts
03
Trace API

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.

47.2k
traces / second
04
Finality receipts

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.

94.6%
reads at depth ≥ 12

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.
