The platform's main differentiators include: adherence to regulations, technical features like blockchain for transparency, and security measures such as user verification  (KYC/AML). 

Use cases span various sectors, including real estate, renewable energy, venture capital, DAOs, and community-based businesses, with an environmental focus on reducing paper consumption and carbon footprint. 

Stellar is chosen for its efficiency, interoperability, transparency, speed, and global payment capabilities, aligning with Stocken Capital's expansion plans across Europe and Mexico.

🧐 What do we already have?

We already have a platform working with Stellar that enables digital governance, investor registration, and trading of company shares as blockchain tokens, with transactions recorded on the blockchain. Each company has a dedicated subdomain. After 2 months after launch, we currently have 300 users and 25 companies. Login into https://pro.stockencapital.com/ and check it for yourself!
 

🤓 What do we want to do now?

We aim to enhance by  transforming the current off-chain flow to buy convertible notes to utilize Stellar and Soroban. Currently, we allow users to purchase convertible notes emitted by enterprises on our platform using traditional payment methods like MangoPay, and an off-chain trusted escrow flow. This submission will focus on 3 key areas:

1. Payment Management. We want all our users to have an Stellar wallet that they will connect only with their email and password by implementing the SEP30 Key Management Standard, charge money to the platform using Stellar Anchors and pay for equity instruments, convertible notes and more through Soroban Smart Contracts.
2. Escrow Management using Soroban. We want to transform our current off-chain trusted flow to use an Soroban Escrow Smart Contract that will lock the users money until a convertible notes contract has been signed.
3. Create a Soroban Oracle. We want to know if users have signed an off chain document through an API endpoint provided by the Signaturit  platform

For our SCF#24 Activation Award, we will focus on transforming the current off-chain flow to buy convertible notes to utilize Stellar and Soroban. Currently, we allow users to purchase convertible notes emitted by enterprises on our platform using traditional payment methods like MangoPay, and an off-chain trusted escrow flow. This submission will focus on transforming this process, implementing anchors, Soroban contracts for escrow, and an Oracle to fetch off-chain data about document signatures.

In particular, our deliverables for this round will be:

(Note that there will be 2 teams working on simultaneously. One will work on Deliverables 1, 2 and 6, and the other team will work on Deliverables 3,4 and 5)

Assumption: Work will start on March 18th 2024.

Deliverable 1: Wallets. Define a non-custodial wallet for each user and company and connect it to their identity. Users will log in using email/password. Private keys will be stored implementing the SEP30 Key Management Standard.

• How to measure: We will grant the reviewer access to the code and documentation. The reviewer will be able to log in to our platform and view their wallet address, balance, and signed documents. The reviewer will also be able to recover their account.
• Estimated Start Date: March 18th 2024.
• Estimated Duration:  2 weeks
• Estimated Delivery Date: April 5th 2024
• Budget $ 9,309

Deliverable 2: Stellar Anchors. Implement a Stellar Anchor Platform and SEP-6 so users can onboard and have a balance in a Stellar-based digital EUR (possibly EURC from Mykobo). Users will also be able to off-ramp.

• How to measure: We will grant the reviewer access to the code and documentation. The reviewer will be able to log in to our platform, onboard, and off-ramp.
• Estimated Start Date: April 8th 2024
• Estimated Duration: 2 weeks
• Estimated Delivery Date: April 26th 2024
• Budget $ 4,654

Deliverable 3: Oracle. Creation of a Soroban-based Oracle to fetch signature information.

• Description: Our convertible notes are generated on our platform and sent to the Signaturit platform. Signaturit provides an endpoint so we can determine when the document has been signed. We need to pass this information to the Soroban Escrow contract so the funds can be unlocked. This deliverable includes unit and integration tests.
• How to measure: Code will be available on our GitHub.
• Estimated Start Date: March 18th 2024.
• Estimated Duration: 2 weeks
• Estimated Delivery Date: April 5th 2024
• Budget $ 4,654

Deliverable 4: Escrow. Creation of a Soroban Escrow Smart Contract:

• Description: Escrow will depend on the signature status. Once the document has been signed, it releases the payment. The signature can be canceled, and the payment can be recovered. This contract also mints an NFT representing an on-chain backup of the signed document.
• How to measure: Code will be available on our Github
• Estimated Start Date: April 8th 2024
• Estimated Duration: 2 weeks
• Estimated Delivery Date: April 26th 2024
• Budget $ 4,654

Deliverable 5: NFT. Implementation of NFT in Soroban to backup the signed document:

• Description: Implementation of an NFT storing the signed document hash. This NFT will be minted when the convertible note escrow has been released as proof of the note.
• How to measure: Code will be available in our Github
• Estimated Start Date: April 29th 2024
• Estimated Duration: 2 weeks
• Estimated Delivery Date:May 17th 2024
• Budget $ 4,654

Deliverable 6: Backend and Frontend: 

• Description: Adapt the existing backend, converting Web3 elements to Soroban.
• How to measure: Successful integration with Soroban.
• Estimated Start Date: April 29th 2024
• Estimated Duration: 2 weeks
• Estimated Delivery Date: May 17th 2024
• Budget: $4,654

This current grant (SCF #24) will help us to work during 1.5 months and complete the deliverables exposed above. However in order to complete our Stellar and Soroban implementation in house we’ll need 2 more stages. We expect to deliver a good product to the community in order to apply for our Second and Third stages for new SCF grants.

1. First Stage. Current SCF #24. Q1 2024. 6 weeks of development.
2. Second Stage. Q2 2024. 12 weeks of development.
   Main Deliverables:
   1. NFT Smart Contract Integration: Implement a smart contract to manage evidence storage through NFTs. This includes storing hashes of signed Convertible Notes documents as a persistent, on-chain backup, initially set with a TTL of 6 months. A backend cron job will ensure the TTL never falls below 5 months, maintaining document integrity.
   2. Signatures Oracle Implementation: Integrate a simple, permissioned oracle standard to read values from a specific API endpoint, leveraging Signaturit for digital signature management. This will facilitate real-time data verification and enhance security measures for document handling.
   3. Stocken Administrative and Escrow Smart Contracts: Deploy contracts initialized with a specific token (EURC), enabling Stocken Capital to onboard new enterprises and users. These contracts will support the creation and management of convertible notes, linking them to pending signatures and locking tokens as necessary. A feature will be added to abort and retry the signature process if needed, ensuring flexibility and control over transactions.
3. Thirst stage Q3 2024. 10 weeks of development. 
   1. Marketplace Launch for Convertible Notes: Open a secondary market for users to sell their convertible notes through NFTs. This function will trigger an API in the Signature Platform, prompting the signing of a new document and the storage of a new hash, facilitating a seamless transfer process.
   2. Design and Interface Enhancements: Implement new design and interface improvements for the newly added functionalities, focusing on user experience and platform usability.
   3. Testing and Deployment: Conduct implementation testing in both TEST and PRODUCTION environments, followed by a detailed report. This phase ensures that the platform and its new features are thoroughly vetted and fully functional before being released to the public.

The founders, Rafael, Carlos, and Victor, originated from Block Impulse, where, since 2018, we've been collaboratively developing blockchain projects with our skilled team. As a successful company in this field, we persist in supporting other projects using blockchain technology. Additionally, we operate our platform for launching ICOs and STOs, maintain our NFT Marketplace, handle custom developments, manage smart contracts, utilize arbitration bots, and facilitate cryptocurrency payments.

Even if the development will be in-house, we have partnered with Esteban Iglesias (@esteblock) from PaltaLabs that will provide us with technical advice in our journey to implement Soroban and Stellar.
