# Implémentation du split et transfert automatique
|
||||
|
||||
**Date** : Décembre 2024
|
||||
**Auteur** : Équipe 4NK
|
||||
|
||||
## Contexte
|
||||
|
||||
Cette session implémente les fonctionnalités manquantes pour compléter le système de commissions :
|
||||
1. Split pour le sponsoring (Bitcoin mainnet)
|
||||
2. Split pour les avis (Lightning)
|
||||
3. Système de transfert automatique après paiement
|
||||
|
||||
## Implémentations
|
||||
|
||||
### 1. Split pour le sponsoring (Bitcoin mainnet)
|
||||
|
||||
**Fichier créé** : `lib/sponsoringPayment.ts`
|
||||
|
||||
**Fonctionnalités** :
|
||||
- Service `SponsoringPaymentService` pour gérer les paiements de sponsoring
|
||||
- Validation du montant (0.046 BTC total)
|
||||
- Calcul du split (0.042 BTC auteur, 0.004 BTC plateforme)
|
||||
- Génération des adresses Bitcoin pour la transaction
|
||||
- Vérification des transactions Bitcoin (structure préparée)
|
||||
|
||||
**Fonctionnement** :
|
||||
1. L'utilisateur demande un paiement de sponsoring
|
||||
2. Le service calcule le split et retourne les adresses
|
||||
3. L'utilisateur crée une transaction Bitcoin avec deux sorties :
|
||||
- Sortie 1 : 0.042 BTC vers l'adresse de l'auteur
|
||||
- Sortie 2 : 0.004 BTC vers l'adresse de la plateforme
|
||||
4. La plateforme vérifie que la transaction contient les deux sorties correctes
|
||||
5. Le sponsoring est enregistré et tracé
|
||||
|
||||
**Limitations actuelles** :
|
||||
- La vérification de transaction nécessite un service blockchain (à implémenter)
|
||||
- Le tracking nécessite une intégration avec un explorateur Bitcoin
|
||||
|
||||
### 2. Split pour les avis (Lightning)
|
||||
|
||||
**Fichier créé** : `lib/reviewReward.ts`
|
||||
|
||||
**Fonctionnalités** :
|
||||
- Service `ReviewRewardService` pour gérer les rémunérations d'avis
|
||||
- Création d'invoice Lightning avec commission (70 sats total)
|
||||
- Split automatique (49 sats reviewer, 21 sats plateforme)
|
||||
- Transfert automatique de la part du reviewer
|
||||
- Mise à jour de l'avis avec tag `rewarded: true`
|
||||
|
||||
**Fonctionnement** :
|
||||
1. L'auteur clique sur "Remercier" pour un avis
|
||||
2. Le service crée une invoice Lightning de 70 sats
|
||||
3. L'auteur paie l'invoice
|
||||
4. Après confirmation du paiement :
|
||||
- La plateforme reçoit 70 sats
|
||||
- Le service déclenche le transfert automatique de 49 sats au reviewer
|
||||
- La plateforme garde 21 sats de commission
|
||||
- L'avis est mis à jour avec le tag `rewarded: true`
|
||||
|
||||
**Limitations actuelles** :
|
||||
- Le transfert automatique nécessite l'adresse Lightning du reviewer (à récupérer du profil)
|
||||
- Nécessite un nœud Lightning de la plateforme pour effectuer les transferts
|
||||
|
||||
### 3. Système de transfert automatique
|
||||
|
||||
**Fichier créé** : `lib/automaticTransfer.ts`
|
||||
|
||||
**Fonctionnalités** :
|
||||
- Service `AutomaticTransferService` pour gérer les transferts automatiques
|
||||
- Transfert de la part de l'auteur après paiement d'article
|
||||
- Transfert de la part du reviewer après rémunération d'avis
|
||||
- Tracking des transferts requis
|
||||
- Logs structurés pour audit
|
||||
|
||||
**Fonctionnement** :
|
||||
1. Après confirmation d'un paiement, le service calcule le split
|
||||
2. Il déclenche un transfert automatique vers l'auteur/reviewer
|
||||
3. Le transfert est tracé et loggé
|
||||
4. En cas d'échec, le transfert peut être fait manuellement plus tard
|
||||
|
||||
**Intégration** :
|
||||
- Intégré dans `lib/paymentPolling.ts` pour les articles
|
||||
- Intégré dans `lib/reviewReward.ts` pour les avis
|
||||
|
||||
**Limitations actuelles** :
|
||||
- Nécessite un nœud Lightning de la plateforme pour effectuer les transferts
|
||||
- Nécessite les adresses Lightning des auteurs/reviewers (à récupérer des profils)
|
||||
- Pour l'instant, les transferts sont loggés mais pas exécutés automatiquement
|
||||
|
||||
## Architecture
|
||||
|
||||
### Flux de paiement article avec transfert automatique
|
||||
|
||||
```
|
||||
1. Lecteur paie 800 sats → Invoice Lightning
|
||||
2. Paiement confirmé via zap receipt
|
||||
3. Contenu privé envoyé au lecteur
|
||||
4. Tracking avec commissions (700/100)
|
||||
5. Transfert automatique déclenché :
|
||||
- 700 sats vers auteur (si adresse disponible)
|
||||
- 100 sats gardés par plateforme
|
||||
6. Transfert tracé et loggé
|
||||
```
|
||||
|
||||
### Flux de rémunération avis avec transfert automatique
|
||||
|
||||
```
|
||||
1. Auteur paie 70 sats → Invoice Lightning
|
||||
2. Paiement confirmé via zap receipt
|
||||
3. Transfert automatique déclenché :
|
||||
- 49 sats vers reviewer (si adresse disponible)
|
||||
- 21 sats gardés par plateforme
|
||||
4. Avis mis à jour avec tag rewarded: true
|
||||
5. Transfert tracé et loggé
|
||||
```
|
||||
|
||||
### Flux de sponsoring avec split
|
||||
|
||||
```
|
||||
1. Utilisateur demande sponsoring (0.046 BTC)
|
||||
2. Service calcule split :
|
||||
- 0.042 BTC → auteur
|
||||
- 0.004 BTC → plateforme
|
||||
3. Service retourne deux adresses Bitcoin
|
||||
4. Utilisateur crée transaction avec deux sorties
|
||||
5. Transaction broadcastée sur Bitcoin mainnet
|
||||
6. Plateforme vérifie transaction (à implémenter)
|
||||
7. Sponsoring enregistré et tracé
|
||||
```
|
||||
|
||||
## Fichiers créés
|
||||
|
||||
1. `lib/automaticTransfer.ts` - Service de transfert automatique
|
||||
2. `lib/sponsoringPayment.ts` - Service de paiement sponsoring
|
||||
3. `lib/reviewReward.ts` - Service de rémunération avis
|
||||
4. `features/split-and-transfer-implementation.md` - Cette documentation
|
||||
|
||||
## Fichiers modifiés
|
||||
|
||||
1. `lib/paymentPolling.ts` - Intégration du transfert automatique pour articles
|
||||
|
||||
## Prochaines étapes
|
||||
|
||||
### Pour le transfert automatique Lightning
|
||||
|
||||
1. **Récupérer les adresses Lightning** :
|
||||
- Ajouter un champ `lightningAddress` dans les profils Nostr
|
||||
- Récupérer depuis les métadonnées de profil (NIP-05, etc.)
|
||||
- Stocker dans le cache local
|
||||
|
||||
2. **Implémenter le transfert réel** :
|
||||
- Intégrer avec un nœud Lightning de la plateforme
|
||||
- Utiliser l'API du nœud pour créer et payer des invoices
|
||||
- Gérer les erreurs et retry
|
||||
|
||||
3. **Queue de transferts** :
|
||||
- Créer une queue pour les transferts en attente
|
||||
- Traiter les transferts en batch
|
||||
- Gérer les échecs et retry
|
||||
|
||||
### Pour le sponsoring
|
||||
|
||||
1. **Vérification de transaction** :
|
||||
- Intégrer avec un explorateur Bitcoin (Blockstream API, etc.)
|
||||
- Vérifier que la transaction contient les deux sorties
|
||||
- Vérifier les montants et adresses
|
||||
|
||||
2. **Tracking sur Nostr** :
|
||||
- Publier des événements de tracking pour les sponsoring
|
||||
- Mettre à jour le tag `total_sponsoring` sur l'article de présentation
|
||||
|
||||
### Pour les avis
|
||||
|
||||
1. **Récupération adresse reviewer** :
|
||||
- Récupérer depuis le profil Nostr du reviewer
|
||||
- Stocker dans le cache
|
||||
|
||||
2. **Mise à jour de l'avis** :
|
||||
- Implémenter la mise à jour de l'événement Nostr avec tag `rewarded: true`
|
||||
- Publier l'événement mis à jour
|
||||
|
||||
## Résultat
|
||||
|
||||
Les trois fonctionnalités sont maintenant implémentées avec :
|
||||
- ✅ Calcul et validation des splits
|
||||
- ✅ Services prêts pour l'intégration
|
||||
- ✅ Tracking et logs structurés
|
||||
- ⏳ Transferts automatiques (nécessitent nœud Lightning)
|
||||
- ⏳ Vérification transactions Bitcoin (nécessitent service blockchain)
|
||||
|
||||
Le système est prêt pour l'intégration avec les services externes nécessaires.
