Invoice NFT
The Faktur Pajak as an ERC-721 token, locked in its vault, drawn onchain as SVG with a status stamp, and burned when the claim ends.
FakturNFT (symbol FKTR) is an ERC-721 whose token ID is the invoice ID. The registry mints it into the invoice's vault at verification, and it cannot be transferred. It is the onchain claim on the invoice: as long as it sits in a vault, that invoice is spoken for.
Lifecycle
| Event | NFT |
|---|---|
| Verified | Minted to the vault, stamp VERIFIED |
| Financed | Still in the vault, stamp FINANCED |
| Repaid / Defaulted / Funding failed | Burned; the picture keeps LUNAS, DEFAULT or UNFUNDED |
Burning on close means a live token always equals a live claim. Wallets and marketplaces never show a token for an invoice that is already settled.
Onchain image
FakturRenderer builds the image from the registry, so it works even after the token is burned:
svg(invoiceId)returns the raw 400×520 SVG: Faktur Pajak number, amount in rupiah, invoice date, due date, buyer NPWP hash and token ID (both shortened), and the stamp.tokenURI(invoiceId)returns adata:application/json;base64,…document with name, description, the SVG asimageand attributes Status, Amount (IDR) and Due date.
FakturNFT.tokenURI delegates to the renderer; the admin can swap renderers with setRenderer without touching tokens. The app shows the picture on Borrow, Lend and Check, because the token never reaches a user wallet.
