StarInvoice

An invoice-based escrow protocol for freelancers, built on Stellar using Soroban smart contracts.

Overview

StarInvoice lets freelancers create on-chain invoices and receive payment through a trustless escrow flow. The client funds the invoice, the freelancer marks work as delivered, and funds are released upon approval — no intermediaries needed.

Status

This project is intentionally minimal. The create_invoice function is implemented. All other escrow functions are stubbed with TODO comments and open GitHub issues for contributors to pick up.

Contract Flow

create_invoice → fund_invoice → mark_delivered → approve_payment → release_payment
