1.2 Top up your balance directly via Registry smart contract

Funding the user’s balance directly via Registry smart contract will take just a minute.

First, click on the name of the network where you want to top-up your balance, e.g. Polygon Mumbai.

This will take you to the contract address page on the respective explorer, e.g. polygonscan.

After that, click on “Write Contract”, and then click again on “fundBalance”. Enter the number of tokens (e.g. MATIC) you want to add to your balance and press “Write”.

Once you confirm the transaction in your wallet, your balance within Nerif App is topped up.

The algorithm is the same for all the other supported networks (e.g. Ethereum Goerli, BSC Testnet, and Gnosis Chiado).
