/ Chain Coverage Directory

38 chains. One indexer. Every block since 2017.

CryptoWorlds tracks every block, every asset, and every labeled wallet across the multichain economy — L1s, L2s, app-chains, and testnets — so your watchlist, your alerts, and your research aren't gated by which data provider covers which chain.

/ Directory · Grouped by Tier

Every tier of the multichain economy — indexed.

The directory isn't filtered to the top 10 by market cap. We cover base-layer settlement chains, the rollups and validiums built on top of them, the app-chains shipping their own consensus, and the testnets where the next mainnet is hardening.

Tier 01

Layer 1 Settlement

Base-layer chains with their own validator set and consensus. The foundation of the indexer.

/ Query Any Address, Any Contract, Any Chain

One API surface across 38 chains.

A single endpoint resolves to the right chain, the right decoder, and the right label set. Trace a wallet's cross-chain footprint, build a PnL table from raw transfers, or fire a webhook the moment a contract emits a specific event. The indexer does the parsing; you get the data.

Will this work for my stack?

The four questions that determine whether CryptoWorlds is a fit — answered directly.

Does CryptoWorlds support chain X?

If a chain is on the directory above, yes — mainnet, all historical blocks, every contract event, every token transfer. If a chain isn't on the directory, we don't currently index it; the indexer is added for chains with sustained validator activity and on-chain economic weight. The most recent additions were Berachain, Blast, and Mode — each within 72 hours of block zero. We don't speculate on chains that haven't launched.

How far back does your index go?

The first block ever indexed by CryptoWorlds was Bitcoin's block 455,667 in March 2017 — the first block after SegWit activation. Every chain since mainnet genesis is indexed in full; 612TB of historical chain data is stored across redundant hot and cold tiers. There are no gap-fills, no sampling, and no retroactive reorgs older than the chain's finality window.

What about L2s, app-chains, and testnets?

All three are first-class. L2s are indexed from their respective mainnet launches — Base since block 1, Arbitrum since 2021-09, Scroll since 2023-10. App-chains like dYdX, Celestia, and Berachain are indexed as independent chains with their own block explorers and label sets. Testnets are indexed for researchers tracking launches before mainnet listing; data is marked as testnet in every response.

Can I track a wallet across every chain at once?

Yes. The resolve endpoint takes an address and a list of chains (or "all") and returns the cross-chain footprint — labeled entity, category, confidence score, per-chain transfer counts, and first-seen timestamp. The same endpoint underpins the smart-money wallet tracking in the Watchlist product: 2.4M labeled addresses, refreshed every 90 seconds.

Don't see your chain? We add new mainnets within 72 hours of block zero — and we'll backfill full history from genesis.
