Financial Transparency in Bitcoin: Wallet Auditing Through UTXO

What is UTXO and Why Should You Monitor It?

Bitcoin doesn’t use the traditional balance model you’d find in banking systems. Instead, it relies on the UTXO (Unspent Transaction Output) model, where each unspent output acts like a “coin” — a piece of Bitcoin that belongs to you and can be used in future transactions.

Here’s the key point: if you want to know exactly how much Bitcoin a wallet (i.e. a group of addresses) held at any given moment in the past, you need to analyze the UTXO state for that specific point in time.

That’s where the magic begins.

Poolsar.io — An X-ray Tool for Your Bitcoin Wallets

Poolsar.io is a powerful platform that lets you:

• Track UTXOs in real time or for any historical date across all addresses added to a wallet

• Work with wallets as collections of addresses — either manually added or generated from an xpub

• Restore wallet state — see how much Bitcoin was held, in which UTXOs, and when they were received

Who Is This For?

The UTXO state restoration feature is especially useful for:

• Crypto funds that need accurate asset accounting

• Companies and individuals preparing reports (including for tax or compliance purposes)

• Developers and enthusiasts who need a clear historical view of wallet activity

Why Does It Matter?

UTXO isn’t just a technical detail — it’s the foundation of how Bitcoin works.

If you’re not monitoring UTXOs, you’re missing the full picture.

With Poolsar.io, you gain access to precise, historical wallet data.

Clear. Reliable. Transparent.
