Findora Academy 💟 | How to Use Rialto Bridge — A Mini Tutorial

Welcome to our final article discussing the newly launched cross-chain bridge, Rialto, that connects Findora to BNB Chain (and, later on, other EVM-compatible blockchains like Ethereum). See our earlier overview and deep dive articles for more information.

Findora’s AMM DEX Ecosystem

Rialto is the first cross-chain bridge built to access the growing DeFi market of zk dApps deployed on Findora. Findora decentralized exchanges (DEXs) include FairySwap🧚‍♀️ and Be sure to visit these project links to check for any APY promotional campaigns.

Rialto Bridge Promotional Campaign

For the mainnet Rialto Bridge launch, a $5m bridge fee reimbursement promotion was launched. Click here to participate and earn free FRA!

When migrating assets over from BNB Chain to Findora Network, we estimate the total fees to be under $2.00 worth of BNB on the BNB Chain side — as of March 14, 2022 BNB pricing of ~$373.

More specifically, gas fees on the BNB Chain side of the bridge will be about ~250,000 gas units (~$0.47 worth of BNB) and on Findora’s side about ~370,000 gas units. (about $0.000087 worth of FRA). Bridge transactions consist of a deposit transaction on the BNB chain side and 3 transactions (1 execution and 2 voting) on the Findora side. The entire bridge transaction typically takes less than 30s to complete under normal conditions.

Below are the key steps to perform on Rialto Bridge to move assets over from a source network (such as BNB Chain) to a destination network (such as Findora networks).

Step 1: Configure Metamask for both BNB Chain and Findora

Goto Metamask’s “Add Network” screen and configure Metamask to connect with BNB Chain using the settings below:

Next, go to Metamask’s “Add Network” screen again and configure Metamask to connect with Findora using the settings below:

Step 2: Fund Metamask with BNB Tokens

Rialto bridge transactions whose assets originate from BNB Chain must pay BNB gas fees on the BNB Chain side of the bridge. Thus, you must first buy or transfer BNB tokens into your BSC Mainnet Metamask wallet. If you don’t have BNB tokens, you can buy them from an exchange like or any of the exchanges listed on this page.

Step 3: Transfer Tokens Across Bridge

Goto and connect your BNB Chain Metamask wallet. Next set the “Source Network” to BNB Chain. Enter the token type and token amount you wish to send from BNB Chain to Findora. Enter your destination (Findora) wallet address and click “Start Transfer”. To send the funds to the same destination wallet address (i.e. set both sending BNB Chain address and receiving Findora address to the same value), click the “I want to send funds to my address” checkbox.

Step 4: Confirm Metamask Transaction

Metamask will ask you to confirm your transaction. Click “Confirm” on the screens below.

Step 5: View Transaction Details on EVM Block Explorer

To view the completed bridge transaction log, goto Enter your wallet address into the search bar at upper right of the block explorer and hit enter. Next, click on the “Token Transfers” tab and look for the “Token Minting” success message. A successful bridge transaction will lock your token on the BNB Chain side of the bridge and mint a new, corresponding token on the Findora side of the bridge.
