By Soroban Payout & Token Suite
Through this submission, we aim to implement three Soroban smart contracts on the Stellar network that will extend the SimplyTokenized platform into a fully on-chain, transparent, and compliant tokenization framework.
Token Contract – Enables issuance, minting, burning, and capped supply management for tokenized assets.
Stellar Impact: Leverages Soroban’s WASM runtime for secure asset issuance and aligns with Stellar’s SEP-41 token standards for interoperability.
Crowdsale / Sale Router Contract – Facilitates multi-stablecoin token sales (USDC, EURC), pricing logic, whitelisting, and fund routing.
Stellar Impact: Utilises Stellar’s native stablecoin anchors and cross-contract calls for atomic, auditable sales transactions.
Payout / Redemption Contract – Supports three payout modes: off-chain bank transfers, claim portal redemptions, and on-chain wallet payouts.
Stellar Impact: Uses Soroban contracts for transparent redemption tracking, linking real-world settlements to Stellar’s ledger.
These improvements will transform SimplyTokenized from a centralized platform to a hybrid Web3 infrastructure, enabling secure on-chain token management, verifiable sales, and automated payouts within the Stellar ecosystem.
Our success will be measured through both technical outputs and ecosystem impact achieved with the project completion.
Output Metrics:
3 Soroban smart contracts (Token, Crowdsale, Payout) fully developed, audited, and deployed on the Stellar testnet and mainnet.
3–5 enterprise pilots launched using the new on-chain modules for token issuance and investor payouts.
10+ users interacting with on-chain functions through the SimplyTokenized platform.
Open-source release of Soroban smart contract templates and documentation for community reuse.
Impact Metrics:
Increased adoption of Stellar by enterprises for compliant tokenization and financing use cases.
Improved transparency and auditability of asset issuance and redemption through Soroban’s on-chain logic.
Bridging traditional finance and blockchain by connecting corporate clients, stablecoin anchors (USDC/EURC), and investors within the Stellar ecosystem.
Overall, success means proving that regulated, real-world tokenization can operate seamlessly and securely on Stellar, setting a foundation for wider enterprise adoption and long-term ecosystem growth.

The SimplyTokenized platform is already live and operational, demonstrating strong early traction and validation within the asset tokenization domain.
Our primary web application is available at:
We operate in the DACH region (Germany, Austria, Switzerland), serving clients in the fintech and digital asset management sectors. Founded in 2019, SimplyTokenized initially focused on clients in Austria and later expanded operations into Germany and Switzerland. Currently, we work with four active enterprise clients within our core industries, collectively managing tokenized and digitized assets valued at approximately €10 million.
See how issuers and operators implemented tokenization with measurable outcomes—liquidity, reach, cost reduction, and compliance. Case Studies
These partnerships highlight the platform’s adoption by corporate clients in real estate, mining, and alternative asset financing, validating both business demand and product-market fit.
The current submission builds on this validated off-chain foundation by introducing Soroban-based on-chain smart contracts for issuance, sales, and payouts on Stellar.
MVP - Backend implementation of Soroban Architecture
Description:
Backend architecture integration for Soroban contract invocation, transaction orchestration, and event indexing
Measurement: At least 10 Soroban transactions executed end-to-end through backend orchestration
Token Contract Implementation
Description: Development of the SimplyTokenized Token Contract using OpenZeppelin patterns (Ownable, Pausable, ERC20-like structure) adapted for Soroban. Supports minting, burning, and capped issuance.
Measurement:
Deployed and validated on local Soroban environment; 99% unit test coverage.
Crowdsale / Sale Router Contract
Description:
Implementation of the Sale Router to manage multistablecoin intake (USDC, EURC) with dynamic pricing, whitelisting, and purchase caps. Utilises OpenZeppelin’s SafeMath and Access-Control.
Measurement:
Integration test with simulated stablecoins and role-based user permissions.
Payout / Redemption Contract Specification
Description:
Technical specification of the three payout modes—bank transfer, claim portal, and on-chain wallet payout—designed with OpenZeppelin’s Role-Based Access Control (RBAC).
Measurement:
Approved specification with internal review and security assessment.
Integrated Testnet Deployment
Description:
Deployment of the Token, Crowdsale, and Payout contracts on Soroban Testnet. Includes OpenZeppelin Defender setup for monitoring and administration.
Measurement:
End-to-end workflow validated; all contracts interact successfully on Testnet.
Wallet Integration & Transaction Signing (Testnet)
Description:
Integration of Stellar-compatible wallets into the SimplyTokenized platform to enable secure user signing and submission of Soroban transactions on Testnet.
Measurement:
Successful signing and submission of Soroban transactions via Freighter and Stellar Wallets Kit
Smart Contract Hardening and Security Engineering
Description:
Execution of in-depth smart contract security engineering and hardening for the Token, Sale Router, and Payout contracts on Soroban. This deliverable focuses on strengthening contract correctness, resilience, and upgrade safety through engineering-led security work, following Stellar Soroban best practices and OpenZeppelin secure design principles.
Measurement:
All contracts pass expanded adversarial and edge-case test suites
Payout Functionality Tests
Description:
Implementation and test execution of all three payout modes using mock data and sandbox APIs for off-chain components.
Measurement:
100% transaction success rate achieved in a controlled test environment.
Mainnet Deployment and Verification
Description:
Deployment of audited and verified contracts to Stellar Mainnet using OpenZeppelin AdminUpgradeabilityProxy to ensure maintainability and controlled updates.
Measurement:
Verified contract hashes on-chain; mainnet transactions confirmed by three independent wallets.
Technical Documentation and Governance Package
Description:
Publication of comprehensive developer documentation, API references, and governance model in alignment with Open-Zeppelin standards. Set up continuous monitoring using Defender for uptime and security tracking.
Measurement:
Documentation available on GitHub; system uptime 100% during the first 30 days post-launch.
Pilot Integrations and Development-Led Validation
Description:
Development-led onboarding and technical support for a small set of pilot integrations to validate real-world usage of the deployed Mainnet contracts. This deliverable focuses on hands-on integration work, SDK usage, contract interaction support, and iterative improvements driven by real transaction flows.
Measurement:
At least three pilot integrations are successfully interacting with Mainnet contracts

Collectively, our team has previously built and deployed the SimplyTokenized Platform, a live cloud-based system for asset tokenization and investor management. This platform is already in use by multiple European clients for corporate financing and digital asset management.
We now aim to extend this expertise into the Stellar ecosystem by implementing the Soroban smart contract layer for on-chain token issuance, sales, and payouts.
