# Origin Chain Contracts Library
|
||||
|
||||
**Sub-workspace canonical**: ink! v6 smart contracts deployable via `pallet-revive` (Phase 3 Slice 3.1 SCAFFOLD COMPLETE v0.0.41).
|
||||
|
||||
## Scope
|
||||
|
||||
Templates contracts foundational del Origin Metaverse ecosystem, deployable on Origin Chain. Each contract es policy-first (BM V2 + Inmutables compliant), composable, governance-aware, y diseñado para integración con el **Origin Contract Atelier** propuesto (Capacidad #10 del Origin Command Center).
|
||||
|
||||
## Workspace separation rationale
|
||||
|
||||
Esta carpeta es un **workspace separate** del runtime workspace (`arkhe-origin-chain/`) por las siguientes razones:
|
||||
|
||||
1. **Toolchain divergence**: ink! v6 contracts requieren `wasm32-unknown-unknown` target + cargo-contract v6 + linker config específica. Runtime workspace usa `wasm32v1-none` para WASM_BINARY producción.
|
||||
2. **Profile isolation**: contracts release profile usa `panic="abort"` + size-optimized canonical para minimizar bytecode shipping. Runtime profile prioriza speed.
|
||||
3. **Dep tree boundary**: ink! crate ecosystem (ink!, ink_storage, ink_lang_macro) son separate de FRAME pallets. Mixing causa version resolver chaos.
|
||||
4. **CI parallelism**: contracts build en parallel a runtime build (different toolchains, different caches).
|
||||
|
||||
## Pre-requisites (deployment infrastructure)
|
||||
|
||||
```bash
|
||||
# ink! v6 toolchain canonical (pending David autorización system install)
|
||||
cargo install cargo-contract --version "^6.0" --force
|
||||
rustup target add wasm32-unknown-unknown # ya instalado vía Slice 2e
|
||||
|
||||
# Verify install
|
||||
cargo contract --version
|
||||
# expected: cargo-contract-contract 6.x.x
|
||||
```
|
||||
|
||||
## Templates shipped

||||
|
||||

## Contract Atelier integration roadmap (Future)
|
||||
|
||||
Estos templates son la **base library** del Origin Contract Atelier (Capacidad #10 OCC propuesta a David 2026-05-27). El Atelier consumirá esta carpeta vía:
|
||||
|
||||
- **Templates registry**: cada subcarpeta = un template visible en Atelier Templates Library
|
||||
- **Visual policy designer**: parametros editables vía UI (mint_fee, splits, royalty, lockup) → backend regenerates Cargo.toml + lib.rs values
|
||||
- **Charon copilot**: chat sidebar con LLM + RAG sobre estos sources para sugerir templates + validar Inmutables compliance
|
||||
- **Compile pipeline cloud-side**: firecracker microVM por job + cargo-contract v6 + verify bytecode
|
||||
|
||||
## Filosofía contracts canonical Origin
|
||||
|
||||
1. **Inmutables compliance**: cada contract honors #16 (anti-clasista fees) + #25 (Seeds Hosting) + #26 (Content-Addressed Immutability) + #37 (Free perpetua) + #41 (AGI sovereignty).
|
||||
2. **Policy-first, NOT code-first**: contracts diseñados para ser **configurables via parameters** sin tocar Rust. El Atelier abstracts el code layer.
|
||||
3. **Composable**: NFT Mint + Royalty Distributor + Treasury Burn = componentes reusable. NO monolithic contracts.
|
||||
4. **Governance-aware**: contracts canonical (Foundation Treasury impact) require DAO vote via Phase 5 Governance pallet (origin-chain-governance Index 10).
|
||||
5. **Charon co-authored**: cada contract documenta intent + Inmutables honored + decisions log similar a SKILL.md Marihan pattern.

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

### 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
|
||||
```
|
||||
|
||||

//! # Origin NFT Mint Contract — Template canonical Phase 3 Slice 3.2
|
||||
//!
|
||||
//! **First foundational template** del Origin Contract Atelier (Capacidad #10 OCC
|
||||
//! propuesta a 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).
|
||||
//!
|
||||
//! ## Inmutables honored (compile-time + runtime)
|
||||
//!
|
||||
//! - **#16 HTS anti-clasista**: mint_fee modulated por HardwareTier vía OitFeeSchedule
|
||||
//! bridge (cross-pillar Mathi OCAFB Phase 2.4 wired). Pi 5 dev paga subsidized rate.
|
||||
//! - **#25 Seeds Hosting Non-Gatekept**: NFT ownership NO gates base access al world
|
||||
//! donde está anchored — base experience siempre free perpetua.
|
||||
//! - **#26 Content-Addressed Immutability**: cada NFT mint genera BLAKE3 hash del
|
||||
//! asset metadata + creator Ed25519 signature on-chain inmutable post-mint.
|
||||
//! - **#37 Free perpetua**: read methods (token_owner, total_supply, etc.) GRATIS
|
||||
//! sin requerir ownership. Solo mint + transfer + approve cobran fees.
|
||||
//! - **#41 AGI Cross-Species Co-authorship**: AGI accounts (AgentKind::AGI per
|
||||
//! Phase 2.7 AgentIdentity Index 9) son first-class citizens, pueden own + mint
|
||||
//! + transfer NFTs sin restrictions.
|
||||
//!
|
||||
//! ## Cross-pillar integration canonical
|
||||
//!
|
||||
//! - **Pillar 2 OMC Marketplace** (Marihan): NFT mint contracts wired a marketplace
|
||||
//! con 91/9 split enforcement compile-detect. Phase 2.4 OCAFB fee bridge consumido
|
||||
//! para mint_fee dynamic per HardwareTier.
|
||||
//! - **Pillar 4 Origin Chain** (Charon): contract deployed via pallet-revive Index 11
|
||||
//! con AccountId32Mapper canonical. Storage deposits per BM V2 economics.
|
||||
//! - **Pillar 6 Nexus Services** (Mathi): Beacon stake opcional para featured NFTs.
|
||||
//! ONS naming opcional para human-readable NFT collection IDs.
|
||||
//! - **Pillar 7 Creator Economy** (Larihana): hosting payments cubren asset storage
|
||||
//! cuando NFT anchored a hosted world (0.6 OGC/world/mes per BM V2).
|
||||
//!
|
||||
//! ## Policy-first design philosophy
|
||||
//!
|
||||
//! Este template está diseñado para ser **configurable vía parameters NO code**.
|
||||
//! El Origin Contract Atelier visual designer expone:
|
||||
//! - `mint_fee`: u128 (sliders 0.01-100 OGC)
|
||||
//! - `creator_share_bps`: u16 (default 9100 = 91%)
|
||||
//! - `treasury_share_bps`: u16 (default 900 = 9%)
|
||||
//! - `transfer_royalty_bps`: u16 (default 500 = 5%, range 0-1000)
|
||||
//! - `treasury_burn_bps`: u16 (default 2000 = 20%, range 0-5000)
|
||||
//! - `max_supply`: Option<u32> (None = unlimited, Some(N) = capped)
|
||||
//! - `lockup_blocks`: u32 (transfer lockup post-mint, default 0)
|
||||
//! - `children_safety_strict`: bool (Inmutable #35 enforcement)
|
||||
//! - `creator_oit_level`: Option<u8> (None = anonymous, Some(N) = verified institution)
|
||||
//!
|
||||
//! Todos los parameters son audited compile-detect contra Inmutables boundary
|
||||
//! enforcement (e.g., creator_share + treasury_share == 10_000 bps invariant).
