Aave Horizon: VBILL Treasuries Become Collateral, What It Means
A new integration expands collateral types on the protocol’s new chain: Aave Horizon accepts VanEck’s VBILL as eligible collateral. The change enables borrowing of stablecoins against tokenized treasuries while linking pricing and transfer-agent systems, and it clarifies institutional access to on-chain lending.
How do VBILL tokenized treasuries become usable collateral on Horizon?
The integration makes VBILL, VanEck’s first tokenized fund, eligible collateral on Horizon. In this context, holders can use VBILL to borrow stablecoins, effectively converting short-term treasury exposure into on-chain lending power.
However, the upgrade depends on on-chain pricing and custody signals to meet compliance and accounting needs.
In practice, institutional custodians require a verified chain of custody and regular NAV cadence before accepting tokenized funds as collateral.
Operationally, integrating transfer-agent signals with oracle-delivered NAV reduces reconciliation risk and allows Horizon to quantify haircuts and concentration limits more precisely.
Securitize described VBILL as “providing real-time access to U.S. Treasury-backed assets,” reflecting its design for institutional cash management: Securitize press release.
What role do Chainlink NAVLink feeds and trusted NAV pricing play?
The integration is powered by Chainlink NAVLink feeds to deliver regular fund valuation on-chain. As a result, these feeds provide a verified net asset value (NAV) which Aave Horizon uses to size collateral and determine borrowing capacity.
Trusted pricing therefore reduces slippage and uncertainty for lenders and borrowers.
Meanwhile, reliable valuation is critical because Horizon has surpassed $532 million in total market size as of November 06, 2025, reinforcing the importance of precise NAV updates.

How does the Securitize–VanEck partnership affect RWA collateral lending and institutional DeFi liquidity?
The Securitize–VanEck partnership creates a bridge between traditional fund mechanics and on-chain lending.
VBILL converts short-duration treasuries into tokenized units, and Horizon accepting those tokens as eligible collateral is intended to increase institutional DeFi liquidity. That said, the move should broaden access to RWA collateral lending without altering the underlying fund structure.
What systems ensure VBILL accounting and trusted NAV pricing?
Securitize’s transfer agent systems ensure VBILL collateral is fully accounted for, preserving investor records and ownership.
In addition, Chainlink NAVLink provides periodic, auditable pricing to Aave’s risk module, enabling Horizon to apply consistent valuation rules. Accuracy in transfer records and NAV publication are both necessary for regulatory alignment and to maintain market trust.
How will Securitize’s TSSO integrate and what changes for lenders?
Securitize’s TSSO will be integrated to coordinate on-chain settlement with traditional transfer-agent duties. Moreover, the integration aims to ensure off-chain legal ownership maps to on-chain token balances, reducing reconciliation friction for collateral liquidation and margin calculations.
As a result, lenders on Horizon can underwrite collateral with clearer documentation and reduced operational risk, supporting broader institutional participation. This follows the integration of TSSO and NAVLink into Horizon’s risk and settlement workflows.
What are the market and product implications for borrowers and lenders?
For borrowers, the main practical effect is that VBILL enables borrowing stablecoins against VBILL holdings, unlocking liquidity without requiring the sale of the fund position. For lenders, the availability of tokenized treasuries as collateral diversifies risk exposures within the protocol.
Nevertheless, protocol risk remains tied to oracle integrity, transfer-agent reconciliation, and governance of risk parameters on Aave Protocol v3.3. Market participants should monitor feed cadence and transfer-agent reconciliations closely.
Which operational details should institutional participants watch?
Key items include NAV publication frequency, the scope of Securitize’s transfer-agent reporting, and Horizon’s risk parameters for VBILL concentration.
Institutions will evaluate capital efficiencies versus custody and compliance workstreams when moving funds into tokenized treasuries. Review the Securitize announcement and Aave’s official market updates to assess timing, custody, and pricing responsibilities before onboarding VBILL as collateral.
