Earn Rewards By Helping Us Test the Polygon-to-Findora Rialto Bridge

Earn Rewards By Helping Us Test the Polygon-to-Findora Rialto Bridge

In the Building Up the Bridge Campaign, you can earn FRA and a Project Galaxy NFT when you cross the bridge on testnet.

The Building Up the Polygon Bridge Campaign

Migrating assets to Findora over the Rialto Bridge lets you enjoy the privacy features Findora offers. Ethereum and BNB Chain are already connected, and the Polygon path is now live on testnet.

To stress-test this new part of the bridge, the Findora Foundation is sponsoring the Building Up the Bridge Campaign. Complete the campaign to win $5 worth of FRA, receive a Project Galaxy NFT, and help expand the future of privacy finance to more of web3.

Let’s dive in:

How To Test the Bridge and Win Rewards

You can test the Rialto Bridge in three easy steps:

  1. Configure your MetaMask wallet to the Findora Anvil and Polygon Mumbai Testnets and get testnet MATIC and FRA tokens.
  2. Bridge USDT from Polygon to Findora and then back to Polygon
  3. Bridge a testnet NFT from Findora to Polygon and then back to Findora.

First, you’ll need to enter the campaign here and complete the social tasks. After that, here’s a breakdown on how you can test the bridge:

Step 1: Get Set Up By Configuring MetaMask and Getting Testnet tokens from Faucets

If you haven’t already, you’ll need to add the Findora Anvil Testnt and Polygon Mumbai Testnet to your MetaMask Wallet. Open MetaMask, click on the network at the top, and select Add Network.

Here’s the RPC information you’ll need to enter:

Polygon Mumbai

Findora Avil:

Next, you’ll need testnet MATIC and FRA tokens. To get Matic, go to the Polygon Mumbai testnet faucet and put in your Polygon Mumbai MetaMask wallet address.

To get FRA tokens, you’ll need to go to the #Faucet channel on Findora’s Discord. In the chat, type “!evm” and then insert your Findora avnil MetaMask address.

Step 2: Bridging USDT Tokens Between Polygon and Findora

With your new MATIC testnet tokens, head to Quickswap to swap them for USDT. After a few minutes, the USDT tokens should appear in your MetaMask wallet.

Next, go to the Rialto Bridge on Anvil testnet and connect your Polygon Mumbai wallet to test the bridge. Make sure you’re going from Mumbai to Anvil and that you select USDT in the asset box.

TIP: You can simply check “I want to send funds to my address” instead of copy/posting your MetaMask wallet address in the destination address box.

Once the transfer is successful, switch to the Findora Anvil network to see the USDT.p you have just bridged over. If you can’t see USDT in your Findora anvil wallet, import the USDT.p token so your wallet can recognize it.

Under the Assets tab, click on “Import Token” and copy/paste the contract address:


The rest of the info should auto-populate but you can input it manually as well:

  • Token Symbol: USDT.p
  • Token Decimal: 6

The USDT tokens may take a few minutes to appear in your Findora Anvil wallet.

Simply reverse the process to bridge USDT.p back to Polygon.

Step 3: Bridging an NFT between Findora and Polygon

To get a testnet NFT, switch your MetaMask to the Findora Anvil testnet and select the ERC721 option. The blue NFT Faucet button should appear. Clicking on it will mint and NFT in your wallet.

NOTE: Be sure to copy the Token ID down!

Input the Token ID and select ZK Mole in the Source Contract Address box. After checking the box to send the NFT to yourself, start the transfer.

Once completed, wait a few minutes before transferring the NFT back to the Findora Anvil testnet. Make sure to switch to the Polygon Mumbai testnet and follow the same steps, being sure to input the same Token ID. You may need to wait around 15 minutes before the transfer back to Anvil will be possible.
