Practical overview
When it fits
Use it as the contract layer when building or integrating Stellar invoice-finance flows that need on-chain participant status, invoice state transitions, liquidity pools and escrow coordination.
Who it is for
- Developers building invoice-finance applications on Stellar.
- Teams integrating contract interfaces and events into an application or SDK.
- Contributors working on Rust-based Soroban contracts or testnet deployments.
Documented uses
- Store issuer and buyer profiles with verification status.
- Create invoice records and enforce lifecycle transitions, including delivery confirmation and repayment.
- Accept liquidity, issue transferable LP shares, fund eligible invoices and account for repayment.
- Coordinate escrow during funding, including configured release and recovery operations.
- Deploy and track separate pool instances by asset through the pool factory.
Requirements & limits
The README describes USDC contracts deployed on Stellar Testnet. It documents Rust 1.85.0, the wasm32v1-none target and Stellar CLI as development prerequisites. The repository specifies an MIT license.
- The contracts coordinate on-chain state and token transfers but do not validate commercial documents or establish invoice legitimacy.
- Attestation-gated listing depends on separately configuring the optional Underwrite agent registry integration.
- The README reports that the contracts have not been formally audited and identifies an issuer payout path not yet wired into invoice funding.
- The documented default deployment targets USDC; XLM deployment is experimental and opt-in.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
Prepare the Rust workspace for a Stellar Testnet deployment
Install the documented Rust components and configure the project’s testnet deployment before running its deployment scripts.
Before you start
- Rust toolchain 1.85.0
- The wasm32v1-none Rust target
- Stellar CLI
- A testnet deployer funded on Stellar Testnet
- Project configuration based on .env.example
Steps
Install Rust toolchain 1.85.0.
Add the wasm32v1-none target for that toolchain.
Configure .env using .env.example and fund a testnet deployer.
Run bash scripts/setup-testnet.sh, then bash scripts/deploy.sh.
Expected outcome
The repository’s scripts are documented for setting up and deploying the contracts to testnet; the deployment process supports resumption and updates the address table.
Guide limitations
- This describes the repository’s documented deployment procedure, not an independently executed deployment.
- The default deployment targets the supported USDC workflow; XLM deployment is experimental and opt-in.
- Contract addresses may change after redeployment. Review the deployment guide for address lifecycle, wiring, verification and rollback details.
- The project reports that its contracts have not been formally audited and warns against using real funds or treating testnet assets as redeemable value.
