Borrow against MAMO
Teller pools accept MAMO as collateral on Base at up to 21.1% LTV, lending USDC at 25% APR. Borrowing takes two transactions, an approval and the borrow itself. Every loan is fixed-term with no margin-call, so a price fall during the loan cannot liquidate your collateral.

Two transactions, and what the first one authorises
Borrowing here takes two signatures rather than one. The first is an approval, which tells the token contract that the Teller contract may move a stated amount of MAMO out of your wallet. The second is the borrow itself, which moves the collateral and sends the USDC back.
The approval is the one worth reading. It is a standing permission on the token contract, not a transfer, and it survives the loan unless you change it. Approving the exact amount you intend to post keeps that permission bounded. Approving an unlimited amount saves a transaction next time and leaves an open allowance behind, which is a trade rather than a mistake, but one to make on purpose.
You can read any allowance you have granted straight off the token contract, and set it back to zero the same way. Doing that after you close a loan is a habit worth having on every token, not just this one.
The row, and the token
The Base pool clears 21.1% of collateral value at 25% APR, lending USDC. That ceiling is at the wider end of the chain’s range, so around five dollars of MAMO back each dollar borrowed rather than the six a narrower row asks for.
The contract sits at 0x7300b37dfdfab110d83290a29dfb31b1740219fe, reads Mamo, and reports a total supply of exactly 1,000,000,000. Check those before the approval rather than after it, since an approval granted to the wrong token contract is a permission you then have to go and revoke.
After the borrow
Interest is charged for the days you hold the loan, so the 30-day cycle costs roughly a twelfth of the annual figure. Rate, LTV and the roll window lock when the loan opens and the pool holds the collateral until you repay or roll.
Every loan is fixed-term with no margin-call, so a price fall during the loan cannot liquidate your collateral, and no second approval is needed part-way through because there is never a top-up to make. Miss the due date and the collateral is forfeit. Base gas is cents on both transactions.

Frequently asked questions
The first is an approval, telling the token contract that Teller may move a stated amount of MAMO from your wallet. The second is the borrow, which moves the collateral and sends the USDC back.
Approving the exact amount you intend to deposit keeps the permission bounded. Unlimited saves a transaction next time and leaves an open allowance behind, so make it a deliberate choice.
Yes. Allowances are readable off the token contract and can be set back to zero the same way. Doing that after closing a loan is a good habit on any token.
No. There is no top-up and no margin call during a fixed term, so nothing further is authorised until you open the next loan.
