Borrow against HYDX
Teller pools accept HYDX, the Hydrex token, as collateral on Base at up to 16.7% LTV, lending USDC at 25% APR. At about 102.7 million tokens it carries the tightest supply of any Base collateral here. Every loan is fixed-term with no margin-call, so a price fall during the loan cannot liquidate your collateral.

An address that starts with five zero bytes
Hydrex sits at 0x00000e7efa313f4e11bfff432471ed9423ac6b30. Those leading zeroes are not decoration and not luck. Addresses are mined for that shape on purpose, because zero bytes in calldata cost less gas than non-zero ones, so every transfer touching the contract is fractionally cheaper for as long as it exists.
For a borrower it is mostly a recognition aid: a token whose deployer went to that trouble is one you can spot in a list at a glance. Verify the full address anyway. A vanity prefix is exactly the sort of thing an imitation copies first.
The tightest float in the Base set
totalSupply answers 102,751,503 tokens. Every other Base asset Teller lends against runs to billions or tens of billions, so this one is smaller by a factor of ten at the least and by a factor of a thousand against the largest. The unit price is correspondingly higher, and a collateral depositing here is counted in ordinary numbers rather than in ten-digit ones.
Supply size does not change the loan. It changes how you read a balance: a few thousand tokens is a real position here, where the same count elsewhere on the chain would round to nothing.
Terms
The pool clears 16.7% of collateral value at 25% APR, lending USDC on Base. That ceiling sits at the conservative end of the chain’s range, so budget around six dollars of collateral for each dollar borrowed. Interest is charged for the days you hold the loan, which puts a 30-day cycle at 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. Miss the due date and the collateral is forfeit. Base gas is cents on both transactions, vanity address or not.
The rest of the chain is on the Base collateral page, and AERO is the other Base protocol token with a page here.
Frequently asked questions
It was mined for that shape. Zero bytes in calldata cost less gas than non-zero ones, so a leading run of them makes every transaction touching the contract fractionally cheaper.
102,751,503, which totalSupply on 0x00000e7efa313f4e11bfff432471ed9423ac6b30 confirms. That is far tighter than the billions and tens of billions the rest of the Base set carries.
Divide one hundred by the ceiling above. This row sits at the conservative end of the Base range, so budget around six dollars of HYDX per dollar of USDC.
The prefix is the easiest part to imitate, so check the full address rather than the first few characters. The pool accepts one contract and rejects everything else at the deposit.
Nothing happens to the loan. There is no liquidation threshold during the term, so your obligation on the due date is unchanged.
