eros-nft

Open standard for predefined AI persona NFT cards on Solana cNFT.

A persona card is a self-contained Solana cNFT that grants the holder permission to chat with a specific predefined AI persona. This repo defines the format, publishes JSON Schema 2020-12 contracts, ships a Rust reference crate (eros-nft on crates.io), and bundles 15 sample personas.

fn main() {

Concepts

A persona NFT card has two document forms:

• PersonaDraft — what a creator submits to a marketplace mint pipeline. Contains the plaintext system prompt and raw avatar source. Lives only in the pipeline; never published.
• PersonaManifest — the published artifact. Suitable for Arweave / IPFS pinning and as the metadata URI of a Solana cNFT. Carries prompt_ciphertext_ref (KMS reference + ciphertext SHA-256), not the plaintext.

The cNFT itself is the chain anchor; the Manifest is chain-agnostic. See spec/v1.0/06-chain-profiles/solana-cnft.md.

Out of scope

• Trained-persona transfer (memory dossier, lineage, training metrics) lives in a separate future spec, eros-nft-extended.
• Marketplace business logic (mint pipeline, royalty enforcement, takedown) lives in eros-chat-marketplace (closed source).
