How to deposit in a Vault

This visual guide will walk you through every step in depositing funds in a Vault


  • You must have the vault's underlying token(s) in your wallet. See here how to fund your wallet.
  • You must use a supported wallet, such as Metamask or Trustwallet.


1. Go to the Champion Optimizer app page:

Again, make sure that your wallet is connected and that it is funded with tokens.

2. Use the filters to find a vault you want to deposit into:

The blockchain logos, the preset selection buttons and the search field all act as filters.

3. Example of filter usage

In this guide, we will use the CHAM-ETH vault on BSC as an example:

4. Inside the vault:

There is a lot of information inside the vault, such as TVL (Total Value Locked), Price and APY (Annual Percentage Yield) historical rates, Token Asset details, and the Vault's compounding strategy.

5. The Deposit and Withdraw module:

The vault already sees we have LP available in our wallet to deposit. There is a "Buy Token" link provided in case you do not have any LP or wish to buy more LP to deposit, as well as a "Bridge CHAM" button to bridge CHAM from another blockchain to BSC (Broken link). A deposit field and a "Max" button are used for entering the exact amount of CHAM you want to deposit. Furthermore, the Vault Fees (Broken link) are shown.

6. An example deposit:

In this example, we first click the "Max" button to deposit all the CHAM in our wallet, followed by clicking on the "Deposit All" button.
When it is the first time you deposit in this vault, you need to grant permission to the vault's contract and allow it to access your funds:
In the next transaction you will be actually depositing in the vault:
In summary, depositing into a new vault always requires two transactions: one for approving the spending permission and one for the actual deposit.

7. Deposit confirmation:

Once the transaction succeeds, a message will pop up confirming the deposit and it contains a link to the transaction in the block explorer. It is very important to understand that your wallet now holds a tokenized proof of deposit called a "coToken". This coToken is required to withdraw from the vault, don't lose it!
On the block explorer page of the deposit transaction you can find out that the coTokens are indeed supplied to your wallet after depositing in the vault. The token transfer will look something like this:
Since coTokens are interest-bearing, they are more valuable than their "normal" token counterpart. This is also the reason why the coToken amount does not 1:1 match with the token amount initially deposited.
That's it, once the harvest function on this vault is called, you are already earning yield!
