# origin-nft-mint — NFT Mint Contract Template (Slice 3.2)

> **Estado (3-nov-2026): borrador de mayo de 2026.** Como crate de Rust compilaba y pasaba sus pruebas en junio, con ink! 6.0.0-beta.1 (commit `6663dbd`; hoy no lo he vuelto a medir). Pero **nunca se ha construido con `cargo-contract` ni se ha desplegado**.
> No es producto ni describe el diseño vigente. Donde este texto diga «ratificado», «garantizado» o «complete», habla de mayo.
> *In English: May-2026 draft. It compiled and passed its Rust tests in June 2026 (6663dbd), but it has never been built with cargo-contract nor deployed. Not a product.*
> **Lo que ya no vale:** el reparto 91/9, la regalía del 5 % y la quema del 20 %. Desde el 2-nov-2026, el 9 % de cada venta del Store se reparte en 6 % para la LLC de la casa y 3 % para el tesoro común, sin quema. Además, el Store será una pallet propia de la cadena, no este contrato (ver el README del repositorio).

**First foundational template** del Origin Contract Atelier (Capacidad #10 OCC propuesta David 2026-05-27). Implementa el split BM V2 ratificado 2026-05-18 91% creator / 9% Treasury + transfer royalty 5% (configurable) + Treasury burn 20% (per BM V2 burn matrix Pillar 3).

## Status

🚧 **SCAFFOLD (source-only, v0.0.42)** — `lib.rs` shipped + Cargo.toml ready. Real compilation deferred hasta `cargo-contract v6` install autorizado (precedent Slice 2e brew LLVM authorization pattern). El source es:

- **Compilable canonical** una vez tooling instalado: `cargo contract build --release`
- **Reference architectural** para Contract Atelier visual designer Phase 3.x
- **Documentation living** del policy-first contract design pattern Origin

## Inmutables compliance compile-detect

| Inmutable | Enforcement canonical en este contract |
|-----------|----------------------------------------|
| **#16 HTS anti-clasista** | `mint_fee_base` modulated por HardwareTier vía OitFeeSchedule bridge Phase 3.x integration |
| **#25 Seeds Hosting Non-Gatekept** | NFT ownership NO gates base world access — purely decorative/economic layer |
| **#26 Content-Addressed Immutability** | `asset_hash: AssetHash` BLAKE3 hash compile-detect required (Error::InvalidAssetHash if zero) |
| **#37 Free perpetua** | Read methods (`total_supply`, `token_owner`, `balance_of`, etc.) sin payment — siempre gratis |
| **#41 AGI Co-authorship** | AccountId32 canonical para AGI accounts (Phase 2.7 AgentIdentity) sin distinction de Human accounts |

## Configuration parameters (Contract Atelier UI exposure)

| Parameter | Type | Default BM V2 | Range UI canonical |
|-----------|------|---------------|---------------------|
| `mint_fee_base` | `Balance` (u128) | 1 OGC (10^18 base) | 0.01 - 1000 OGC sliders |
| `creator_share_bps` | `u16` | 9_100 (91%) | locked invariant 91% canonical (BM V2 ratified) |
| `treasury_share_bps` | `u16` | 900 (9%) | locked invariant 9% canonical (BM V2 ratified) |
| `transfer_royalty_bps` | `u16` | 500 (5%) | 0-1000 (0-10%) sliders |
| `treasury_burn_bps` | `u16` | 2_000 (20%) | 0-5000 (0-50%) sliders |
| `max_supply` | `Option<u32>` | None (unlimited) | None OR Some(1..=4_294_967_295) selector |
| `lockup_blocks` | `u32` (blocks) | 0 (no lockup) | 0-1_576_800 (≈ 6 months Pi 5 6s blocks) slider |
| `children_safety_strict` | `bool` | false | toggle (Inmutable #35 strict mode) |

### Pillar 2 OMC Marketplace (Marihan) wire

NFT mint contracts compose el marketplace canonical Marihan. Cada skill canonical creada en Atelier Skills (Marihan) puede ser minted como NFT via este template. El 91/9 split BM V2 ratified compile-detect garantizado.

### Pillar 4 Origin Chain (Charon) deploy

Deployment vía `pallet-revive::instantiate` Index 11 (Slice 3.1 SCAFFOLD COMPLETE shipped v0.0.41). Storage deposits per BM V2 economics (mint_fee_base default 1 OGC + storage deposit pallet-revive 1 MILLI_OGC/byte + 1 OGC/item).

### Pillar 6 Nexus Services (Mathi) integration opcional

Post-deploy NFT collection puede:
- **Beacon stake** canonical: lockup OGC para featured visibility (100-1000 OGC/mes per ONS_PILLAR_6_NEXUS_SERVICES_V1)
- **ONS name** registration: human-readable collection name (5-1000 OGC/year per BM V2)
- **Oracle KYB**: institutional creators verified Nivel 3+ canonical

### Pillar 7 Creator Economy (Larihana) hosting

NFT anchored a world pagado canonical 0.6 OGC/world/mes hosting. NFT transfer canonical preserva world ownership context (NFT changes hands, world hosting continues canonical).

## Deploy instructions (Phase 3.x post cargo-contract v6 install)

```bash
# 1. Install ink! v6 toolchain canonical (pending David authorization)
cargo install cargo-contract --version "^6.0" --force

# 2. Build contract canonical
cd contracts/origin-nft-mint
cargo contract build --release

# 3. Output canonical files:
# - target/ink/origin_nft_mint.polkavm  (PolkaVM bytecode canonical)
# - target/ink/origin_nft_mint.json     (ABI metadata canonical para frontends)
# - target/ink/origin_nft_mint.contract (combined bundle canonical)

# 4. Deploy via Polkadot.js Apps OR Charon Atelier (Phase 3.x maduración):
# - upload_code(origin_nft_mint.polkavm) → CodeHash
# - instantiate(code_hash, constructor=default_bm_v2, value=storage_deposit)
# - Returns contract AccountId32 + H160 mapped address
```

## Tests canonical (unit tests included)

3 tests canonical en `#[cfg(test)] mod tests`:

1. **`default_bm_v2_constructor_canonical_invariants`** — verifica defaults BM V2 ratified (91/9 + 5% royalty + 20% burn + unlimited supply + no pause).
2. **`invalid_share_split_rejected_canonical`** — invariant compile-detect: creator_share + treasury_share MUST sum 10_000 bps (100%). 90% + 5% rejected.
3. **`excessive_royalty_rejected_canonical`** — invariant: transfer_royalty_bps ≤ 1_000 (10% industry standard). 15% rejected.

Run canonical post-install:
```bash
cargo test --features ink-as-dependency
```

## Roadmap follow-up post Slice 3.2

| Ship | Slice | Scope |
|------|-------|-------|
| v0.0.43 | 3.3 | origin-escrow contract template (multi-party + time-locked) |
| v0.0.44 | 3.4 | origin-credential-mint contract (Ed25519 + BLAKE3 Sussi Ethos) |
| v0.0.45 | 3.5 | origin-staking contract (validator + beacon + reputation) |
| v0.0.46 | 3.6 | origin-mdk-reconciliation (ink! vs origin-mdk WASM boundary) |
| Phase 3.x | — | cargo-contract v6 install + real compilation + ReviveApi exposure (deferred Slice 3.1) + integration tests E2E reales |
