Description

Celar is a stablecoin payments infrastructure API that enables developers and payment service providers to accept, route, and settle on-chain payments using USDC, USDT, and other supported stablecoins. It provides a unified backend for pay-ins, smart wallet–based payment attribution, automated confirmation via on-chain listeners, and webhook-driven settlement updates. Celar is designed to be chain-agnostic and developer-first, with a focus on production-ready payment flows.

Progress During Hackathon

During the hackathon, we integrated the Mantle chain into Celar’s payments infrastructure and enabled gasless transactions using Biconomy smart accounts and paymaster support. We implemented support for multiple stablecoins, including USDC and USDT, and built deterministic smart wallets per payment to ensure accurate payment attribution. The system includes on-chain listeners that automatically detect incoming transfers, confirm payments, and trigger webhook notifications, allowing the full pay-in flow to run end to end on Mantle chain.
