Make any NFT collection permanent.

A Forever Twin is a permanent, on-chain counterpart for an existing NFT, bound 1:1 to the original through Xtrata. No re-mint. No migration. When the old link rots, the art lives on.

First public collection: Bitcoin Pepes · live on Stacks

Permanent media records for existing collections

Forever Twins packages the Xtrata protocol into a collection-specific recovery path: original token in place, on-chain twin added beside it, public verification always available.

01

Write the asset on-chainXtrata stores the permanent counterpart instead of relying on a gateway or pinning bill.

02

Bind it to the originalThe holder keeps one side of the pair while the contract enforces the relationship.

03

Keep campaign UX customPartner pages can carry their own collection identity, like the Fak.fun-led Pepes page.

The model

One permanent twin, bound to your original

Most NFTs don't store their art — they point to a file on a server or gateway that can disappear. Forever Twins fix that for collections that already exist, without asking holders to migrate anything.

1

Inscribe

The original token's artwork is written permanently and fully on-chain via Xtrata, and a forever twin is bound to it 1:1.

2

Bound & inseparable

One of the pair is always escrowed in the contract; the holder always keeps the other. They can be swapped, but never split apart.

3

Finalized forever

Each twin carries a canonical content hash. Once finalized, that record is immutable — independent of any hosting bill, gateway, or company.

If your art depends on IPFS gateways, centralized servers, or pinning bills, your collection has infrastructure risk. Forever Twins gives it a permanent on-chain counterpart — without re-minting or migrating holders.

Forever Twins create a permanent on-chain counterpart on Xtrata; they do not repair an original collection's existing off-chain art or pointer.
