# Proposal to Launch Helper Contract (Auto-Buy DBR)
**Forum Link:** https://forum.inverse.finance/t/proposal-to-launch-helper-contract-auto-buy-dbr/191
This proposal aims to introduce a helper contract meant to assist FiRM users in buying DBR and selling DBR as a part of the borrowing and repayment transactions, and thus foregoing the need to procure DBR via any external website.
**Summary:**
FIRM, the new fixed rate lending market from Inverse Finance, makes use of a new DeFi primitive, DBR, to forego traditional interest rates.There is no interest rate for borrowing DOLA in FiRM. FiRM uses the DBR token to let you lock in a fixed rate.
A FiRM user simply holds DBR in their wallet to service the loan and the DBR balance will decay over time - in proportion to the size of their loan.
DBR must be present in a user’s wallet prior to borrowing DOLA on FiRM. Previously, this required one to purchase DBR on Balancer and/or Uniswap before attempting to open a position, but, assuming this proposal passes, the introduction of the helper contract will allow for the cost of a DBR purchase when taking out a loan to be added to your DOLA debt. The FiRM helper contract is designed to assist users in buying DBR as a part of the borrowing transaction, and will require a one-time transaction approval along with a signature.
The helper contract also allows users to withdraw collateral and sell their DBR in a single transaction when repaying their debt.
Finally, the helper function also contains methods to allow users to interact with FiRM WETH markets, without needing to convert their native Eth first.
**On-Chain Actions:**
* Borrow Controller: Whitelist Helper contract address to allow it to interact with FiRM markets.
