Verify your Bitcoin against the chain.

Paste an xpub or descriptor: Wump pulls your real on-chain balance, surfaces every transaction, and tells you where your records and the chain disagree. Bitcoin only.

  1. You paste an xpub or descriptor. Single-sig, multipath, or sortedmulti multisig: all parse natively.
  2. Wump reads the chain. Real balance, every transaction, sat-denominated.
  3. You see the delta. Matched, Only on-chain, Only in Wump.

Paste your own xpub above, or sign up to verify your full wallet history.

Bitcoin-only credibility

Descriptor-native. BIP-380/389.

Single-sig, multipath, or sortedmulti multisig: they all parse.

Paste a single-sig xpub, a multipath descriptor, or a sortedmulti multisig: they all parse the first time. New to descriptors? They're how modern Bitcoin wallets describe themselves. Wump speaks the standard.

Verification hash over fixed canonical fields.

The badge is evidence, not a trust claim.

Every verified transaction is pinned to a SHA-256 hash over a fixed set of fields, plus an immutable snapshot of the on-chain inputs, outputs, fee, and block height. If the record ever drifts from what was on-chain, the badge changes and we tell you.

Sats where they matter. BTC where they don't.

Fees in sats and sat/vB. We don't round 732,841 sats to 0.0073 BTC.

Balances under 1 BTC default to sats. Fees show in sats and sat/vB. You can flip to BTC any time. We don't round 0.0073 BTC when "732,841 sats" is the honest number.

Bitcoin only. No NFTs. No DeFi. No "we'll add it."

The restraint is the product.

Other currencies appear as fiat-style references: price-only, never as portfolio assets. We support Bitcoin and only Bitcoin. The restraint is the product.

The row you forgot was on-chain.

Most trackers ask you to trust them. Wump shows you what's actually on-chain, what you've recorded, and where they disagree.

Three states: Matched (your record and the chain agree), Only on-chain (a transaction the chain has and you don't), Only in Wump (a transaction you recorded and the chain hasn't seen). One click resolves each.

Your record matches the chain.
The chain has it. Your record doesn't.
You recorded it. The chain hasn't seen it.

We can’t move your money

We can’t move your money. Wump never asks for a private key, a seed phrase, or signing access. Wallets are added as xpubs or output descriptors: read-only by construction. If our database were stolen, no attacker could spend a satoshi.
