The context.

A blockchain rail still has to fit into a complete payment product: customer flows, funding confirmation, provider APIs, payout handling, and operational evidence. This engagement explores those connections in a prototype and testnet setting.

My contribution.

  1. Connect Stellar funding and payout workflows to application APIs.
  2. Implement funding verification using Horizon evidence and testnet payment checks.
  3. Work on endpoint flows for crypto-to-fiat, fiat-to-crypto, and crypto-to-crypto journeys.
  4. Organize provider integration modules and backend orchestration for payment workflows.
  5. Contribute to integration planning around customer registration, KYC, funding, and settlement.

The result.

  • Successful testnet payment and funding-verification checks.
  • Backend integration work connecting on-chain events with application payment flows.
On-chain confirmation is one part of settlement. A usable product must also explain provider state, customer state, and the off-chain outcome.
