Introduction to Ramp

Ramp is our user-friendly feature that allows you to seamlessly manage, exchange, and transfer digital assets from one currency to the other.

Ramp is currently divided into two main categories:

1. Cryptocurrency: In this category, you can manage your crypto assets directly. It enables you send crypto from your meCash wallets to other crypto wallets and withdraw crypto to other wallets or exchanges.

2. Off-Ramp: This category is for converting digital assets to fiat money.

In this guide, we’ll walk you through how to fund and withdraw from your Ramp wallet.

Networks and Tokens

Before funding your account, it's important to understand these key concepts:

1. Networks: These are blockchain ecosystems where transactions occur. Ramp supports:

• Polygon (specifically Polygon Amoy testnet): A layer-2 scaling solution for Ethereum that offers faster and cheaper transactions

• Ethereum: The original smart contract blockchain.

2. Tokens: Digital assets that exist on these networks. At meCash we support:

• USDC (USD Coin): A stablecoin pegged 1:1 with the US dollar that exists as an ERC-20 token on both Polygon and Ethereum networks
• Tether (USDT): Another USD-pegged stablecoin. it is also available in ERC-20 format.
• Polygon (MATIC): The native token of the Polygon network.
• Ethereum (ETH): The native token of Ethereum network.

How to Fund your Ramp Wallet

1. Access the Ramp Section

• Navigate to the Ramp section on the left side of the main menu.

• Ensure you're on the correct network (Polygon Amoy in this case).

2. Deposit

• Select the "Deposit" option on any of the specific token you want to fund.

• You'll see a wallet address displayed.

• Important warnings:
  • Only send the currency that matches the wallet's currency you want to fund. e.g USDC to USDC wallet only.
  • Other assets sent will be lost permanently.
  • Ensure you're sending from a Polygon-compatible wallet.

Important Notes

1. Network Compatibility: Always ensure the sending and receiving networks match (e.g. Polygon to Polygon).
2. Token Standard: Only send ERC-20 standard USDC tokens.
3. Address Verification: Double-check the wallet address before sending funds.
4. Transaction Times: Polygon transactions are typically fast (a few minutes), but may vary based on network congestion.
