Nexus Pay

We’re building a seamless multi-chain payment platform for users and merchants. A user pays with any supported token, we use the Avail Nexus SDK to handle cross-chain deposits/withdrawals behind the scenes, while autonomous agents built using the Hedera Agent Kit communicate via the A2A standard, coordinate the payment flow, and settle funds. On the merchant side, we provide a real-time analytics dashboard powered by Blockscout APIs, showing token flows, chain usage and payment trends, letting merchants focus on business, not bridging or routing while finally settling in USDC / Stablecoin for broader adoption.

🛠 Tech Stack & Core Components • We used the Avail Nexus SDK for cross-chain deposit/withdraw flows. It supports multiple EVM-chains, unifies balances and simplifies bridging/swapping from the user side.  • On the agent / workflow side we used the Hedera Agent Kit (via the Hedera ecosystem) for building autonomous or semi-autonomous agents that can execute transactions, monitor events and communicate using standards (A2A / multi-agent).  • For analytics and merchant dashboard, we leveraged the Blockscout APIs/SDK to pull transaction histories, balances and chain info so merchants can get transparent data.
