BlockTailor

BlockTailor is a multi-chain blockchain explorer and data service for Bitcoin, Litecoin, Ethereum, and TRON. Its platform lets users search any supported network by address, transaction hash, or block height, and browse current and historical blockchain activity. BlockTailor says its data is indexed and served on its own infrastructure, with live comparisons against each chain’s node to show index status and coverage. It also provides certification information for indexed histories and offers an API, including a no-key demo and an endpoint tester.

The explorer presents recent blocks, transaction counts, network status, and fee conditions. For Bitcoin and Litecoin, it also displays mempool activity and projected next-block fee rates. Additional network information includes Bitcoin and Litecoin difficulty adjustments and halving schedules. BlockTailor supports mainnets and testnets, and provides contact, privacy, and terms information for users and developers. The service describes its data as provided as-is, without warranty, and states that its pages contain no ads, trackers, or third-party requests.
