Rewards: Leaving the Rewards Contract

Removing tokens from the StandardRewards contract requires the user to indicate the program ID and the token amount. The following steps explain how to collect the data necessary to call the leave function that returns the bnTokens to your wallet. Once the bnTokens are back in your wallet, you can reclaim your deposit by following the instructions in the Withdraw Tokens guide.

1. Program ID

This step will explain how to identify the ID of the rewards program you are staked in:

• Visit StandardRewards contract on etherscan

• Execute the providerProgramIds function (this is a Read function) with your Ethereum address:

Input variable

Name	Type	Description
_provider	address	User wallet address

Output response

List of 1+ IDs to represent the different programs you are staked in

Save the IDs that are returned for use in later steps.

2. Identify which ID to use

If you only have 1 ID (extracted in step 1), skip to step 3.

If you are actively staked in more than 1 program, this step will explain how to identify the program ID for the rewards program you would like to unstake from

• Visit StandardRewards contract on etherscan

• Execute the programs function (this is a Read function)

Input variable

Name	Type	Description
ids	uint256	An array of 1 or more reward program IDs

Output response

Name	Type	Description
id	uint256	The unique identifier of the rewards program
pool	Token	The deposited token (i.e BNT, ETH, DAI, LINK) address
poolToken	IPoolToken	The relevant bnToken address
rewardsToken	Token	The address of the rewards token that is given in this program
isEnabled	bool	True/False indication if the program is active
startTime	uint32	The start time of the program
endTime	uint32	The end time of the program
rewardRate	uint256	The amount of tokens per second that are distributed

Using the output data,

1. Identify the program with the pool token you would like to withdraw

2. Identify the program id to use in the following step

3. Available amount

This step will explain how to identify the number of available tokens to unstake from the contract

• Visit StandardRewards contract on etherscan
• Execute the providerStake function (this is a Read function)

Input variable

Name	Type	Description
provider	address	Your wallet address
id	uint256	The unique identifier of the rewards program

Output response

Name	Type	Description
Amount	uint256	The bnToken amount staked into the rewards program

Note the number returned by the function - this is the number of pool tokens you own, which you will need to input to leave the rewards contract. Note that this value is already returned in wei format, so you will not need to add zeroes to it.

4. Leaving the StandardRewards Contract

This step will explain how to call theleave function, removing your tokens from the rewards program.

• Visit StandardRewards contract on etherscan
• Execute the leave function (this is a Write function)

Input variable

Name	Type	Description
id	uint256	The unique identifier of the rewards program (found in steps 1 and 2)
poolTokenAmount	uint256	The amount of bnTokens to unstake (found in step 3)

Output

The bnTokens will return to your wallet.

Now that once the bnTokens are in your wallet, you can follow the Withdraw Tokens guide.
