# origin-escrow — Multi-party Escrow Contract Template (Slice 3.3)
|
|
|
|
**Second foundational template** del Origin Contract Atelier. Multi-party escrow + time-locked milestones + dispute-enabled via Pillar 6 Tribunal integration.
|
|
|
|
## Use cases canonical
|
|
|
|
| Use case | Parties | Flow típico |
|
|
|----------|---------|-------------|
|
|
| **Freelance contracts** | Cliente + Freelancer + Tribunal | Deposit → milestones met → progressive releases |
|
|
| **OMC marketplace** (Marihan) | Buyer + Seller + Tribunal | Deposit → asset delivered → release. Dispute → refund. |
|
|
| **Institutional partnerships** | Universidad + Researcher + Tribunal | Multi-milestone investigation funding |
|
|
| **Refundable event tickets** | Organizer + Holder + Tribunal | Deposit guarantee → event held → release. Cancel → refund. |
|
|
|
|
## State machine canonical
|
|
|
|
```
|
|
┌──────► Created ──deposit──► Active ──confirm_milestone──► Releasing
|
|
│ │
|
|
│ ├──raise_dispute──► Disputed
|
|
│ │ │
|
|
│ │ └──resolve_dispute──► Completed
|
|
│ │
|
|
│ └──all milestones complete──► Completed
|
|
└────────────────────────────────────────────────────────────────┘
|
|
```
|
|
|
|
5 estados terminales: `Created → Active → Disputed → Releasing → Completed`.
|
|
|
|
## Inmutables compliance
|
|
|
|
| Inmutable | Enforcement |
|
|
|-----------|-------------|
|
|
| **#16 HTS anti-clasista** | escrow_fee_bps capped 5% BM V2 §5.3 ceiling. Pi 5 institutional rate Phase 3.x |
|
|
| **#26 Content-Addressed Immutability** | terms_hash + description_hash BLAKE3 inmutable post-deploy |
|
|
| **#37 Free perpetua** | 9 read methods sin payment (state, depositor, beneficiary, milestones, etc.) |
|
|
| **#41 AGI Cross-Species** | AGI accounts pueden ser any party (depositor, beneficiary, arbiter) |
|
|
|
|
## Resolution canonical (Tribunal options)
|
|
|
|
4 resolution patterns canonical para Tribunal:
|
|
|
|
1. **ReleaseToBeneficiary**: 100% remaining → beneficiary (work completed satisfactorily)
|
|
2. **RefundToDepositor**: 100% remaining → depositor (work not delivered / fraud)
|
|
3. **SplitFifty**: 50/50 split (partial completion / shared responsibility)
|
|
4. **Custom { depositor_bps, beneficiary_bps }**: arbitrary split (e.g., 30/70 partial completion)
|
|
|
|
Invariant compile-detect: `depositor_bps + beneficiary_bps == 10_000` (100%).
|
|
|
|
## Tests canonical (3 unit tests)
|
|
|
|
1. `constructor_canonical_invariants` — valid params + initial state Created
|
|
2. `excessive_fee_rejected_canonical` — 6% fee rejected (>5% ceiling)
|
|
3. `same_party_depositor_beneficiary_rejected` — same address rejected
|
|
|
|
## Cross-pillar integration
|
|
|
|
- **Pillar 4 Origin Chain (Charon)**: deploy vía pallet-revive Index 11
|
|
- **Pillar 6 Nexus Services (Mathi)**: Tribunal contract address = arbiter parameter
|
|
- **Pillar 2 OMC Marketplace (Marihan)**: escrow integrado a marketplace purchases
|
|
- **Pillar 1 Hosting (Larihana)**: refundable hosting fees future use case
|
