Aave Blocks New tBTC Deposits in Ethereum Core Market After Minting Pause

New Deposits and Collateral Borrowing Halted

Aave has stopped accepting new tBTC deposits and tBTC-backed borrowing in its Ethereum (ETH) core market. The restriction followed a suspension of tBTC issuance and redemption by Threshold Network, the protocol that issues the bitcoin-backed token. LlamaRisk, the risk services provider that works with Aave governance, set out the scope in a governance forum post dated October 31: the measure applies only to tBTC in the Ethereum core market, and no other asset in the market is affected. Positions opened before the restriction remain usable. Existing users can keep repaying debt against their tBTC collateral and can withdraw assets, and liquidation of undercollateralized positions proceeds through the market's ordinary process.

The mechanics explain why the two steps landed together. tBTC is a tokenized bitcoin issued by Threshold Network, built to track the Bitcoin (BTC) price, which stands near $77,474 at the time of writing, so TBTC technical analysis moves with bitcoin's own levels rather than with the lending market's parameters. In an Aave market, a holder supplies tBTC as collateral and borrows other assets against it, a structure familiar from margin trading in which the collateral is marked continuously against the outstanding debt. Once Threshold paused minting and redemption, no fresh tBTC could enter the market as collateral, and new borrowing positions against the token were closed alongside it. LlamaRisk's post frames the restriction as a response to the token's own issuance halt rather than a change to risk parameters for other assets. The redemption pause also leaves holders without an exit through Threshold's system, which is why the response blocks new collateral inflow while keeping the exit path inside Aave open for existing depositors.

Scope Confined to One Market's tBTC

Aave's Ethereum (ETH) core market is the protocol's main deployment, settled on Ethereum, the layer 1 blockchain protocol that carries most of the platform's lending activity. Collateral there does not resemble a directional position taken on a perpetual futures venue: a depositor earns supply yield and holds the right to withdraw, while a borrower owes a debt that accrues against the posted asset. The restriction changes only the entry side for tBTC. New supply of the token is refused, and users who hold no tBTC in the market cannot open a borrow against it. Everyone else keeps the rights they had the day before. Users who want to reduce exposure can act without waiting on the issuer: repaying the borrowed asset releases the tBTC collateral, and a withdrawal then moves it out of the market entirely. The forum post sets out these user rights explicitly, which leaves the market's remaining function to exits and repayments rather than to growth.

The trigger sits with the token itself. Minting is the process that creates new tBTC when bitcoin is committed to Threshold's system, and redemption is the process that hands the underlying bitcoin back to a holder; with both suspended, the token's supply cannot grow and existing tokens cannot be redeemed through the issuer. Aave's core market draws its tBTC from that ecosystem, so the freeze on new deposits follows directly from the issuance halt. Nothing in the forum post describes the suspension as temporary or sets a date for it to end. What the post does state is the boundary of the measure: tBTC in the Ethereum (ETH) core market, and nothing else. Liquidations, which are standard in contract trading and in on-chain lending alike, continue to run against tBTC positions whose collateral value falls below the required threshold, so the market's risk engine stays fully in operation while new entries are shut.

What Has to Change Before Entries Reopen

The governing record here is the governance forum post itself, which states the scope of the restriction and the continuation of repayments, withdrawals and liquidations, and says nothing about a timetable. Our reading is that the move is a containment measure tracking the token's own suspension: the lending market closed its doors to new tBTC because no new tBTC can be created or redeemed, not because a borrower failed. Lifting the restriction depends on a step outside Aave's control, namely Threshold Network resuming tBTC minting and redemption. Until that happens, new supply and new borrowing against the token stay blocked, and existing positions unwind on their own terms.
