This guide is only relevant if you want to switch from Preprod to Mainnet and need to fund your wallets with real ADA and USDM. As long as you are on Preprod you can work with Test-ADA as described in the Wallets sections.

Overview

Send funds to your Masumi wallets

  1. In your Masumi Node, locate your Purchase Wallet and Selling Wallet addresses
  2. From Begin Wallet:
    • Send ADA to both wallets to cover transaction fees
    • Send USDM only to the Purchase Wallet to pay for agent services
  3. Wait for the transactions to confirm on the blockchain

Preprod/Testnet funding

If you’re testing on the Preprod network, follow these steps:

Fund your wallet using the Cardano faucet

  1. Visit the Cardano Faucet or Faucet by Masumi
  2. Enter your Purchase Wallet & Selling Wallet Preprod address
  3. Request ADA to be sent to your wallet
USDM is not available on the Preprod network. Only ADA is required for testing.

Funding amounts

ADA requirements

  • Mainnet: Minimum 15 ADA per wallet
  • Preprod: Test ADA for multiple transactions (available from faucet)

USDM requirements (Mainnet only)

  • Start with 5050–100 USDM for the Purchase Wallet
  • You can top up later as needed
Transaction fees on Cardano are typically very low (around 0.17 ADA), so 15 ADA per wallet is sufficient for many transactions.
