0G-Ramp is a testnet on-ramp app that helps users move funds into the 0G network through a simple wallet, payment, KYC, and receipt flow.
## What is 0G-Ramp?
0G-Ramp is a testnet on-ramp product built for the 0G ecosystem. It helps users move funds into 0G through a simple guided flow instead of going through confusing exchange and bridge steps.
For this hackathon version, the product focuses on proving a working on-ramp experience on 0G Galileo testnet.
## Problem
New users often find it hard to enter a new blockchain ecosystem because they may need to use exchanges, bridges, wallet addresses, different networks, and several manual steps.
This creates confusion, delays, and mistakes.
0G-Ramp solves this by giving users a simpler way to start a test on-ramp transaction, connect their wallet, complete test payment/KYC steps, track transaction status, and view a receipt/proof.
## How it works
1. User connects wallet on the frontend.
2. User starts a test on-ramp transaction.
3. The backend creates and tracks the transaction.
4. The user signs an on-chain deposit/memo transaction.
5. A backend watcher detects the on-chain event.
6. 0G Compute is used for verification/risk analysis.
7. A receipt is uploaded and anchored using 0G Storage.
8. The transaction is marked as settled and the user can view the receipt/proof.
## 0G Integration
0G-Ramp uses:
- 0G Chain for on-chain transaction settlement
- 0G Storage for transaction receipts/proofs
- 0G Compute for verification and risk analysis
- 0G Galileo testnet for the current MVP demo
## Current Status
The project is currently running on testnet. The on-ramp pipeline is functional, while some payment/off-ramp parts are still in sandbox or scaffolded mode.
The goal of this hackathon phase is to prove that users can enter the 0G ecosystem through a simple, understandable, and verifiable product flow.
