How to provide liquidity to ViperSwap on Harmony

In this guide we will explain how to provide liquidity to Viperswap pools on the Harmony network to earn swap fees and VIPER rewards.

What is Harmony?

Harmony is a blockchain built for openness and speed. Their mainnet runs Ethereum applications with 2-second transaction finality and 1000 times lower fees. Harmony is an open platform for assets, collectibles, identity, governance. Their secure bridges offer cross-chain asset transfers with Ethereum, Binance and 3 other chains.

What is Viperswap?

Viperswap is an automated market maker (AMM) allowing you to swap harmony tokens instantly on the blockchain. The Viper token is the governance token for the protocol. It is a community driven, fair launched token with no early investors or backers. Token holders can stake on the protocol to earn fees from trading activities.

What you will need to provide liquidity on Harmony Viperswap

  •     Metamask wallet
  •     ONE tokens in your wallet for gas
  •    Two ERC-20 tokens to provide as liquidity on Viperswap 

Setting up the Harmony network with your Metamask wallet

First, you will need to configure your Metamask wallet to connect to the Harmony network. You will need to open Metamask and click on the Network selection dropdown and then click on Custom RPC.

Here is the list of the network parameters so you can easily copy them:

Fill out the empty fields as shown above and click on Save. You will be directly switched to Harmony’s Mainnet now in the network dropdown list. This process adds the Harmony network to the list of available networks you can switch to from within Metamask. Sometimes it is helpful to switch networks when Metamask is acting strange or if you are having trouble getting things to show up.

Move funds to Harmony network

You can use the “Harmony Horizon Bridge” to move tokens over to the Harmony network from Binance Smart Chain or Ethereum. You will need to connect your wallet to the network you are transferring your tokens from and then use the bridge to move them over to the Harmony network.  One thing to note is that the Harmony network uses ONE as gas, so if you bridge over ONE tokens you will have what you need to make a transaction.

Finding the right pool to provide liquidity

To find the best rewards on Viperswap click the “Staking” button to get a drop down menu and then select “Pools” at the top of the page to get to the Farming pools. Listed will be the liquidity pools with the most attractive VIPER rewards.. You will need to click the “Deposit” to get to the interface for adding liquidity. 

Steps to add liquidity to Viperswap

Using this menu you can select a token pair that you would like to provide liquidity to. Remember, you have to put an even proportion of each token into the pool (50/50) and you will typically have to approve each token before you can add liquidity. Luckily on the Harmony network this does not cost very much in gas.

Once you have added the liquidity, you will have Viperswap Liquidity tokens (SLP) in your wallet that you can manage from the Viperswap site and then proceed to stake those SLP tokens to start earning rewards. Viperswap will give a readout of the token balances that indicate your share of the pool based on how many tokens you entered into the pool as shown below.

Stake your VENOM-LP tokens to start earning VIPER rewards

Once you have the VENOM-LP tokens, you can then stake them to earn your VIPER rewards by hitting the “Deposit VENOM-LP Tokens” button and then once it is approved the button will turn into a “Stake” button. Once it is staked, you will start earning your VIPER rewards!

How to withdraw liquidity and what to expect 

In the above picture you will see “Remove” button. Pictured below you will see that Viperswap has a 8% withdrawal free to discourage short term yield farming.

Much like with Uniswap, when you withdraw your liquidity from the Viperswap Harmony pools you will get back a different number of each token than when you started. That is due to the automatic rebalancing that is a core feature of automated market makers (AMM’s). You are able to see this process in action when tracking your tokens on APY.Vision. APY.Vision provides real-time tracking that illustrates the impermanent loss or gain of a liquidity pool position as shown below.


Providing liquidity is a great way to earn some income on tokens sitting in your wallet. You do have to be careful when providing liquidity, as sharp price increases or decreases can have a huge impact on the performance of your position. We suggest using APY.Vision to keep a close eye on your positions to know when to remove liquidity during times of extreme price volatility.
