TradeFlow-Core: Decentralized Trade Finance on Soroban

TradeFlow-Core is the smart contract layer for the TradeFlow protocol. It enables Real-World Asset (RWA) tokenization and decentralized factoring on the Stellar network.

🏗 Architecture

The system consists of two decoupled smart contracts:

1. invoice_nft: A standard-compliant NFT representing a verified invoice. It holds metadata (IPFS hash, face value, currency, due date).
2. lending_pool: An escrow vault where liquidity providers deposit stablecoins (USDC). It accepts invoice_nft as collateral to automate loan origination and repayment.

The following contracts are currently active for frontend integration and testing.
