Transaction effect verification

A successful receipt is not a successful payment.

Veyctum Proof checks what an on-chain transaction actually did before an autonomous workflow takes its next step.

Input
One transaction hash
Verification
Two-provider agreement
Output
Observed effect and evidence
01 / THE PROOF

Do not release the next action on receipt status alone.

The verifier separates what the chain executed from what the workflow needed to happen.

02 / THE FLOW

One clear path from hash to trusted decision.

Veyctum Proof is a small application layer over a live Telegraph Miner. It does not custody funds or pretend to be an escrow contract.

01

Submit the hash

Bring a transaction you already have. The app does not create or move the referenced transaction.

02

Ask Telegraph

A real paid request reaches Miner 9005, which resolves the transaction against independent RPC providers.

03

Read the effect

See the method, status, transfer effect, finality facts, and signal needed for a downstream policy decision.

03 / THE BOUNDARY

Verification is not custody.

The app proves whether the expected payment effect exists. A separate escrow contract or workflow can decide what to do with that fact.

Veyctum Proof does

Observe, compare, explain.

It verifies transaction facts, normalizes supported Base USDC effects, and returns inspectable Telegraph evidence.

Veyctum Proof does not

Hold, settle, or release funds.

The only payment here is the small Telegraph lookup fee on Base Sepolia. The referenced transaction remains untouched.

04 / THE RECEIPT

Built around evidence a workflow can inspect.

The live service keeps the response, signal, and decision boundary visible instead of hiding the important part behind a green checkmark.

Check the effect before the action.

Open the verifier, connect a Base Sepolia wallet, and inspect one transaction through Telegraph.
