Receipts

Last updated October 21, 2026

A receipt is a small JSON document the creator's wallet signs into Arweave the moment a launch confirms. It ties the mint to the creator, the metadata to a hash, and the cost to a transaction. Anyone can verify it in a browser without trusting WICK.

What a receipt contains

{
  "v": 1,
  "app": "WICK",
  "mint": "…pump",                 // the token mint
  "creator": "…",                   // the wallet that signed the create transaction
  "name": "Night Owl", "symbol": "OWL",
  "metadata": "https://gateway.irys.xyz/…",   // the metadata JSON the coin points at
  "metadataSha256": "…",            // SHA-256 of those exact bytes at launch
  "image": "https://gateway.irys.xyz/…",
  "firstBuySol": 0.5, "slippagePct": 10, "priorityFeeSol": 0.0005,
  "simulated": { "ok": true, "unitsConsumed": 123456, "costSol": 0.52011, "tokensOut": 17654321.0 },
  "pool": "pump", "builtBy": "pumpportal trade-local",
  "tx": "…",                        // the create transaction signature
  "slot": 312345678, "confirmedAt": "2026-10-21T14:03:11.000Z",
  "secondsFromClickToConfirm": 19,
  "host": "https://…/"
}

Tags on the Arweave item: App-Name: WICK, Type: receipt, Mint: <mint>, Creator: <creator>, Content-Type: application/json.

What it proves

Claim	How the receipt page checks it
The creator wrote this receipt	Irys data items are signed by the uploader. The page asks the Irys index for the item's owner address and compares it with `creator`. A receipt uploaded by any other wallet fails this check.
The create transaction is real and was signed by the creator	The page fetches `tx` from a Solana node, checks it did not fail, that its fee payer (first signer) is `creator`, and that `mint` is among its accounts.
The mint exists	The page reads the mint account and checks it is owned by the token program.
The metadata has not changed	The page fetches `metadata`, hashes the bytes and compares with `metadataSha256`. Metadata on Arweave cannot change; metadata on a mutable host can, and this check would catch it.

What it does not prove

That the coin is a good investment, that the creator is honest, or that the art is original.
That the creator did not also trade from other wallets.
Anything about trades after the launch. The receipt is a birth certificate, not a history.

Finding a receipt

From the Receipts section on the landing page, paste either a receipt id (opens it directly) or a mint address (queries the Irys index for items tagged App-Name: WICK, Type: receipt, Mint: <mint>). Coins launched anywhere other than WICK, or launched on WICK with the receipt option off, have no receipt.

Why Arweave and not a database

A database WICK ran could be edited, lost, or taken down with the site. Arweave storage is permanent and content-addressed, and the signature on each item belongs to the creator, not to WICK. If WICK disappeared tomorrow, every receipt would still resolve at its gateway address and still verify from the raw JSON.
