Initiating the Withdrawal
Initiating the withdrawal requires depositing your pool tokens into the pending withdrawal contract, starting the cooldown period.
The process consists of 3 steps:

If you are withdrawing your entire balance, you can skip this step and use the total number of pool tokens in your wallet in the WEI format in the following steps.
This step will explain how to calculate the number of bnTokens you need to withdraw to receive a specific number of tokens.
  • Visit the BancorNetworkInfo on etherscan
  • Execute the underlyingToPoolToken function (this is a Read function)
Input variable
Name
Type
Description
pool
Token
The address of the underlying token
amount
uint256
The amount of underlying token you would like to withdraw (in WEI format)
For ETH use 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE

Name
Type
Description
poolTokenAmount
uint256
The amount of bnToken representing the underlying token amount
Save the value as this represent the input amount needed to use in the next steps

In order for the contract to interact with the tokens in your wallet and perform the transaction, an Approve must be set first for the contract.
  • Visit the relevant pool token token contract, for example: bnBNT | bnETH | bnDAI | bnLINK
  • Execute the Approve function (this is a Write function)
spender
The contract address of the BancorNetwork found here
value
The amount you would like to approve (it can be identical or more than the amount you wish to withdraw, BUT NOT LESS) in WEI format as explained here
The number of tokens you approve represents the bnToken you would like to liquidate
  • Click Write to sign the Approve in your wallet

This step will explain how to call the initiate cooldown function
  • Visit BancorNetwork contract on etherscan
  • Execute the initWithdrawal function (this is a Write function)
Input variable
Name
Type
Description
poolToken
Token
The bnToken address (found here)
poolTokenAmount
uint256
The amount of bnTokens to liquidate (found in step 1)
This will initiate the cooldown process and allow to complete the withdrawal
