How to use UniScan to track Bitcoin transactions? (Explorer Guide)

Understanding UniScan Interface

1. UniScan presents a clean, responsive dashboard where users input Bitcoin transaction IDs, addresses, or block hashes directly into the search bar located at the top center of the page.

2. The interface defaults to BTC mainnet mode, ensuring all queries resolve against the live Bitcoin blockchain without requiring manual network selection.

3. Real-time status indicators appear beside each search result, showing confirmation count, timestamp, and fee rate in satoshis per virtual byte.

4. Hovering over any output script reveals its type—P2PKH, P2SH, P2WPKH, or P2TR—with corresponding address formats displayed in both legacy and Bech32m variants.

5. Transaction graphs render UTXO flow visually, mapping inputs to outputs with directional arrows and color-coded value labels.

Navigating Transaction Details

1. Clicking on a transaction hash opens a dedicated detail view containing raw hex data, decoded scriptSig and scriptWitness fields, and full signature validation status.

2. Each input displays the previous output’s transaction ID and index, along with the unlocking script’s execution result—success or failure—and associated error code if applicable.

3. Outputs are listed with precise satoshi amounts, locking script opcodes, and whether they have been spent in subsequent blocks.

4. A collapsible “Related Transactions” section shows all transactions linked through shared inputs or outputs, enabling chain tracing across multiple hops.

5. Timestamps reflect actual block inclusion time, not broadcast time, and are cross-verified against the median time past of the confirming block’s parent chain.

Monitoring Address Activity

1. Entering a Bitcoin address triggers an overview showing total received, sent, and final balance in both BTC and satoshis, updated instantly upon new confirmations.

2. The address page lists all confirmed transactions chronologically, with newest entries first, and includes pagination controls supporting up to 10,000 records per request.

3. Each transaction row highlights whether it is inbound, outbound, or self-transfer based on input/output ownership heuristics applied by UniScan’s clustering engine.

4. Balance history charts plot daily net flow, revealing accumulation or distribution patterns without relying on external APIs or third-party analytics feeds.

5. QR code generation is available for any address shown, rendered inline using SVG format with customizable size and margin parameters.

Using Advanced Search Filters

1. The advanced search panel allows filtering by minimum/maximum confirmation count, transaction size in bytes, fee range, and inclusion within specific block height intervals.

2. Users may combine filters to isolate low-fee transactions stuck in mempool or identify high-value transfers exceeding 1 BTC in a single output.

3. Script pattern matching supports regular expressions targeting specific opcodes like OP_CHECKMULTISIG or OP_RETURN payloads containing ASCII text or hex-encoded metadata.

4. Export options include CSV and JSON formats, preserving all decoded fields including sighash flags, sequence numbers, and witness commitment hashes where present.

5. Search history persists locally in browser storage and remains accessible across sessions unless manually cleared by the user.

Frequently Asked Questions

Q: Does UniScan support SegWit v1 (Taproot) transaction decoding?Yes. UniScan fully decodes Taproot spends, displaying internal key, script path spend details, and Merkle branch verification status for each witness element.

Q: Can I verify if a transaction is replaceable via RBF?Yes. UniScan explicitly marks transactions with opt-in RBF enabled by checking the sequence number of each input against the BIP125 standard.

Q: Is there a rate limit on API access when using UniScan programmatically?Public API endpoints enforce a limit of 60 requests per minute per IP address; no authentication is required for basic transaction lookups.

Q: How does UniScan handle coinjoin transactions?UniScan identifies common coinjoin signatures such as those from Wasabi Wallet or Samourai Whirlpool and labels them accordingly, while preserving full input/output transparency without obfuscation.
