Data API: Bitcoin (BTC) Indexer - performance upgrade

We’ve rolled out a major enhancement to our Bitcoin UTXO Indexer, delivering huge performance gains especially for large wallets with high transaction counts.

The result is significant: ~19× faster performance for key endpoints such as:

📘

Get unspent UTXOs for an address

GET /v4/data/utxos
Explore Docs → Get unspent UTXOs for a specific address up to a specific total amount.

📖

Get the balance of a Bitcoin address

GET /v3/bitcoin/address/balance/{address}
Explore Docs → Get the balance of a Bitcoin address.

This improvement eliminates the limitations of the old indexer, which previously had a hard cap at ~170K transactions before timing out. The new indexer now handles any wallet size. No limits, no timeouts.
