How it works

Spot it.Prove it.Assign it.Close it.

The same records flow through every step, so nobody rebuilds the story from screenshots.

01

Observe

Register what you expect. Watch tells you when it's seen, late or unverifiable.

INV-20418 observed 14:02
02

Compare

Chain, provider and ledger side by side, in exact base units, under a named rule.

No ledger record
03

Investigate

Trace orders the evidence. The case gets an owner, a deadline and a history.

[ What it catches ]

Five ways a payment goes missing on paper.

The exceptions CoinPuffin flags most, from a sample workspace over 14 days.

Exception 01 · Ledger

Ledger record not found

Chain and provider agree. Your ledger has no matching credit yet.

3134% of 92 exceptions · sample data

Exception 02 · Amount

Amount differs

The provider settled 12,950.00 USDC. You expected 13,000.00.

2224% of 92 exceptions · sample data

Exception 03 · Timing

Payment late

An expected payment missed its window, with no transfer observed.

1820% of 92 exceptions · sample data

Exception 04 · Source

Source stale

A feed stopped updating, so the state shows Unknown, never a guess.

1213% of 92 exceptions · sample data

Exception 05 · Duplicate

Duplicate or partial

Two transfers for one invoice, or one that covers only part of it.

Questions ops teams ask

Ask us anything. We answer straight.

CoinPuffin teamEarly access questions
Sample conversation
Payment ops lead

Does CoinPuffin hold or move our funds?

CoinPuffin

No. CoinPuffin is read-only and non-custodial.

It never holds keys, signs transactions or moves funds.

Payment ops lead

Which networks and sources are supported?

CoinPuffin

Early pilots focus on a small set of networks, with Tron, Ethereum and Base as candidates, plus provider and ledger exports.

We confirm coverage for your setup during the connector review.

Payment ops lead

Is this an AML or compliance screening tool?

CoinPuffin

No. CoinPuffin reconciles and investigates your own payment records. It doesn't attribute wallet ownership or score risk.

Payment ops lead

What happens when a source stops updating?

CoinPuffin

Records from that source show as Stale or Unconnected, with their last update time.

So your team can tell “no transfer” apart from “we can't see it yet”.

Payment ops lead

What does it cost?

CoinPuffin

Pricing is set with design partners during early access, based on the networks, sources and volume involved.
