# Blockchain Analytics

To use these endpoints, specify the blockchain from the list below. This API version supports the following blockchains: `bitcoin`, `ethereum`, `litecoin`, `bitcoin-cash`, `doge`, `solana`, `xdc`, `ripple`, `stellar`, `algorand`, `polygon`, `polkadot`, `tezos`, `near`, `avalanche`, and `optimism`.

The Blockchain Analytics Module screens addresses for financial and risk information. Financial details include balances and asset specifics.

Typically, results are provided within 60 seconds depending on your activation plan
