Real assets. Clear rules. Stellar Soroban.

Open-source building blocks for tokenized invoices, property shares, and carbon credits—with eligibility and transfer rules checked by smart contracts.

The idea

Tokenizing an asset is only one part of the work. Applications may also need holder eligibility, transfer policies, and rules tied to an asset’s lifecycle. TrustMint brings those examples together in one inspectable Stellar Soroban repository, so builders can explore the pieces and adapt them for their own testnet prototypes.

TrustMint does not verify identities or provide legal compliance. A trusted verifier records an approval decision on-chain; identity documents and the process behind that decision remain off-chain and under the deploying project’s control.

Explore the building blocks

Building block	What it demonstrates
KYC Registry	Authorized verifiers record approval, tier, jurisdiction, and optional expiry for a Stellar address.
Compliance Engine	Transfer policy examples such as pause controls, address and jurisdiction blocklists, transfer limits, holding periods, and holder caps.
Invoice Token	Invoice metadata with issuance, transfer, settlement, and redemption examples.
Property Token	Fractional property shares with cumulative per-share dividend accounting.
Carbon Credit Token	Credit issuance, transfer, and retirement records with beneficiary metadata.
RWA Reference Token	A separate SEP-41-style token example with KYC and compliance hooks and asset metadata.

The repository also contains a React + Vite dashboard, a TypeScript SDK, deployment helpers, Rust contract tests, and local Stellar integration tests.

How a policy check flows

flowchart LR
  Person[Holder or operator] --> App[Dashboard or SDK]
  App --> Token[Asset contract]
  Token -->|Check approval| KYC[KYC registry]
  Token -->|Evaluate policy| Rules[Compliance engine]
  Token -->|Apply permitted action| State[(Contract state)]
  Verifier[Authorized verifier] --> KYC
  Admin[Authorized admin] --> Rules

Asset contracts invoke the registry and compliance engine during relevant operations. The exact checks depend on the contract and method. An on-chain approval is a record of a verifier’s decision, not proof that an off-chain identity or compliance process is adequate.

Get started

Requirements

• Rust toolchain and the wasm32-unknown-unknown target
• Stellar CLI
• Node.js 20 or newer
• Docker, if you want to run the local integration suite

Build and test the contracts

From the repository root:

rustup target add wasm32-unknown-unknown
cargo build --release --target wasm32-unknown-unknown
cargo test --features testutils

Run the dashboard

cd frontend
npm install
npm run dev

The interface can load without contract IDs. Network-backed workflows need the relevant VITE_*_ID values in frontend/.env. Start from frontend/.env.example. Vite variables are bundled into the browser app, so never put private keys, secrets, or identity documents in them.

Deploy the example suite to Stellar testnet

The helper deploys the KYC registry, compliance engine, invoice token, property token, and carbon-credit token. It writes those IDs to frontend/.env. The separate RWA reference token is not included. The asset metadata in the script is placeholder data; review and replace it before every deployment, including testnet.

bash scripts/setup-identity.sh trustmint-dev
bash scripts/deploy.sh trustmint-dev

Developer commands

# Rust formatting, linting, and contract unit tests
cargo fmt --all -- --check
cargo clippy --all --all-targets -- -D warnings
cargo test --features testutils

# TypeScript SDK
npm run build:sdk

# Frontend
cd frontend
npm run lint
npm run build

The GitHub Actions workflows run formatting, lint, contract tests, WASM builds, and a local Stellar integration job. Passing CI is useful feedback; it is not a security audit or production-readiness guarantee.
