Grant Stream Contracts

Smart contracts for managing grant streams with milestone completion proof hashing and integrated dispute resolution system.

Overview

This repository contains multiple implementations for grant management:

1. Soroban (Stellar) Implementation: High-precision per-second streaming with legal anchoring and cross-chain interoperability.
2. Solidity (Ethereum/L2) Implementation: Milestone-based releasing with integrated dispute resolution and ZK proofs.

Soroban Implementation (Stellar)

Located in contracts/grant_stream/.

Key Features

• Per-Second Accrual: High-precision streaming logic using scaling factors.
• Legal Anchoring: Prevent fund streaming until legal documents are cryptographically signed on-chain.
• Cross-Chain Interoperability: Compact byte-array status emission for bridge monitoring.
• Wrapped Asset Security: Emergency halts and security buffers for non-native assets.
• Yield Treasury: Integration with external yield aggregators for capital efficiency.
