Products & Services

BlindPay is a payment processor that allows you to convert stablecoins into fiat currency or fiat currency to stablecoins.

We don't have custody of users funds, which means we do NOT provide any wallet, and all failed payments will have the funds returned to the same wallet that started the payment. You can check more details here: https://blindpay.com/docs

We also have some customers waiting for stellar integration like Zenith Protocols (https://orbitcdp.finance/) and RampMeDaddy (https://rampmedaddy.com/).

Tranche 1 (Deliverable Roadmap) - MVP

[Deliverable 1]

Implementation of testnet Faucet for stellar assets in our existing developer portal.

How to measure completion: Log into the existing developer portal and have the ability to mint USDC for testing purposes in the Stellar network

Estimated date of completion: 1 week after grant date

Budget: 3,750

[Deliverable 2]

Adapt the current SDK to integrate with Stellar, implementing the proposed flow with Claimable Balances. This involves modifying the SDK and our API, while maintaining compatibility for our current customers. Our company serves customers that are currently in operation and in order to maintain our high standards of security and compliance, a new continuous integration/continuous deployment (CI/CD) pipeline will be set up to test the Stellar workflow thoroughly in an automated environment (using the stellar/quickstart docker image).

How to measure completion: Reviewers can either implement our SDK or use our demo implementation purpose-built for this submission (very lean Stellar wallet with off-ramp capabilities).

Estimated date of completion: 5 weeks after grant date

Budget: 18,750

Tranche 2 (Deliverable Roadmap) - Testnet

[Deliverable 1]

Implementation of the Stellar Signer API, this is so the signing server is segregated from the public API into its own private network and with its own signing validation rules (e.g. as to not sign transactions blindly).

How to measure completion: Updated technical architecture & network diagram for review.

Estimated date of completion: 2 weeks from Grant Date

Budget: 7,500

Tranche 3 (Deliverable Roadmap) - Mainnet

[Deliverable 1]

Integration of the Claimable Balances workflow with all BlindPay features like blockchain screening, KYC levels, transaction monitoring and fiat money transfers.

How to measure completion: End-to-end off-ramp using BlindPay on mainnet.

Estimated date of completion: 2 weeks from Grant Date

Budget: 10,000
