Stock-backed NFTs — Mintr Docs

What a backed collection is

A backed collection connects a fixed maximum NFT supply to a vault holding one approved token.

One token

Every Mintr collection has a vault holding a single SPL backing token.

Approved backing

The token comes from Mintr's approved allowlist. It can be a tokenized stock pool.

Fixed maximum

The creator sets the maximum supply at launch. It can be from 1 to 10,000 NFTs.

The vault

The collection shares one public vault. Each circulating NFT has an equal proportional claim on it.

Shared

There is one vault per collection, not one vault per NFT.

Live

The vault is public and on-chain. The site shows its live balance.

Backing-token units, not dollars

The per-NFT claim is measured in units of the backing token. As fees accrue and top-ups are made, the amount of backing token claimed by each NFT increases. The dollar value of that claim can rise or fall with the market price of the backing token.

Redeeming

A holder can exchange the NFT for its proportional share of the shared vault.

Burn

A holder can burn their NFT at any time and receive its proportional share of the vault in the backing token.

No redemption fee

Mintr does not charge a fee when an NFT is redeemed.

Remaining holders

Burning reduces circulating supply. The per-NFT claim for the remaining holders is unchanged by the redemption.

Reusable slot

A burned slot becomes available to mint again. Supply is capped, not permanently consumed.

How the vault fills

Backing can enter the shared vault from the creator, from other wallets, or from trading fees on a paired coin.

Creator top-ups

The creator can add the backing token from the collection's dev section at any time, in increments.

Anyone can top up

Top-ups are not restricted to the creator. Any wallet can add backing.

Coin trading fees

For a coin-paired collection, trading fees add the paired token to the vault.

The collection page includes a public tracker. It shows cumulative top-ups split between the creator and everyone else.

Coin-paired collections

A collection can be connected to a pump.fun coin priced in a tokenized stock pair.

Launch options

A creator can launch a coin and collection together, launch either one alone, or add a coin to an existing collection later from the collection page.

Custom pair

Coins launch through pump.fun using custom pairs. The coin is priced in a tokenized stock instead of SOL.

Creator fee mode

The creator chooses a fee rate from 1% to 3%.

Matching backing

Creator fees accrue in the paired token. The collection's backing token defaults to that same token, but the creator can override it.

Vault route

Accrued coin fees route into the collection vault. This increases the per-NFT claim in units of the backing token over time.

Coin page

Every coin launched on Mintr has its own page on the site.

Fees

The current fee model is short and specific.

NFT mint

Paid in the collection's backing token to a wallet chosen by the creator.

Redemption

There is no redemption fee.

Secondary sale

There are no royalties on secondary sales.

Platform

Mintr charges no platform fee at this time.

FAQ

Short answers to the main questions about backed collections.

Does each NFT have its own vault?

No. A collection has one shared vault. Each NFT represents an equal proportional claim on it.

Can anyone add backing?

Yes. The creator can add backing from the collection's dev section, and any other wallet can top up the vault.

Can I redeem whenever I want?

Yes. Burn the NFT to receive its proportional share of the vault in the backing token. There is no redemption fee.

Does the backing have a fixed dollar value?

No. The claim is measured in units of the backing token. Its dollar value moves with the market price of that token.

Can a burned slot be minted again?

Yes. Burning lowers circulating supply and makes the slot available to mint again. The maximum supply remains fixed.

Do the coin and collection have to launch together?

No. A creator can launch them together, launch either one alone, or add a coin to an existing collection later from the collection page.

Who receives the NFT mint fee?

A wallet chosen by the creator receives the flat 1% fee in the collection's backing token.
