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. A separate Soroban settlement-contract MVP is deployed on Stellar mainnet, but its source, bindings, submitter, and event indexer are not present in this repository. The broader Stellar application integration remains a target architecture.

​
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
  • A separately deployed Stellar mainnet settlement-contract MVP with three completed lifecycles representing 4,360 USDC of real settlement principal

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 in this repository. The Soroban MVP is deployed separately and has executed request, quote, settler acceptance, deposit, confirmation, and claim calls on mainnet. Its application integration and event-indexing paths remain planned, and a hardened contract must pass specification, testing, independent security review, and controlled release gates before production funds-at-risk use.
