Stop screenshotting prompts.
Sell them.
A prompt is an ERC-7857 iNFT. Hold the token = decrypt the prompt locally and plug into any LLM. On transfer() the key re-seals to the buyer — the seller cryptographically loses access the moment the tx commits.

Six pieces. One sealed asset.
From paste to mint to sale — without ever leaking the prompt body to a server.
01
LiveEncrypt locally
AES-256-GCM key generated in your browser. The prompt body never leaves your machine in plaintext.

02
LiveMint as ERC-7857
The iNFT wraps the encryption key. Owning the token = owning the prompt. Listed on the live Galileo contract.

03
LiveReveal client-side
Ciphertext on 0G Storage, key in your wallet's local browser cache. Plug the prompt into any LLM.
Open →
04
LiveSell · atomic loss
`transfer()` re-seals the key to the buyer. Your local reveal stops working — by cryptography, not promise.
Open →
05
LiveRent · authorizeUsage
Grant an executor N-uses or time-boxed access without selling. Revoke on-chain in one tx.
Open →
06
LiveStarter library
Battle-tested prompts with strict guardrails. Fork, tune, mint as your own iNFT.

A prompt has never been an asset.
PromptBase resells screenshots — anyone with eyes is the new owner. Custom GPTs let you publish, not sell. There has never been a primitive for transferring opaque artifact access with provable loss for the seller. ERC-7857 is that primitive.
