Oynk is building programmable infrastructure that coordinates payment applications, qualified liquidity sources, and local settlement providers across fragmented cross-border routes.
Implementation status matters. This repository currently runs an identity and compliance foundation plus a BSC/Solana settlement-activity visibility plane. The Stellar network and Soroban protocol described in this documentation are the target settlement architecture; no Stellar SDK integration or Soroban contract is present in this repository today.

​
What Oynk does

Oynk separates the customer-facing payment experience from the providers and rails that execute each leg. A future control plane will validate requests, obtain quotes, apply corridor and compliance policy, assign providers, and issue an authoritative settlement reference. Settlement assets can then move through a programmable settlement boundary while local partners deliver the destination value. Today, the implemented platform focuses on visibility and operational foundations:
  • Direct indexing of supported BSC and Solana token transfers
  • Durable PostgreSQL storage, checkpoints, run records, and failure records
  • Public aggregate activity and privacy-safe off-chain transaction reporting
  • Business, settlement-partner, and internal identities with organization-scoped roles
  • Password, OTP, session, CSRF, email-delivery, and business-compliance foundations

Understand the system

Follow a payment from request to payout and see which layers own each decision.

Stellar & Soroban

Read the proposed on-chain settlement and smart-account design, with current gaps clearly labeled.

Run locally

Start PostgreSQL, migrate the schema, and run the API, web apps, and docs.

Operate indexers

Understand replay safety, confirmations, checkpoints, failures, and metric semantics.

​
The holistic model

The solid BSC/Solana visibility path is implemented. The dotted Soroban path is planned and must pass specification, testing, external audit, and deployment review before it can hold or control funds.
