Securitize Expands DeFi Collateral with VBILL Integration on Aave, Powered by Chainlink
November 6, 2025
Securitize CEO Carlos Domingo highlights that integrating VBILL with Aave and Chainlink expands access to trusted on-chain collateral and demonstrates regulated assets moving fluidly through DeFi.
Operational details for institutions to watch include NAV publication frequency, Securitize reporting scope, and Horizon’s risk parameters for VBILL concentration.
The move allows borrowers to gain liquidity without selling fund positions and gives lenders diversified collateral, with the overall impact hinging on governance, custody, and pricing accuracy.
The integration uses on-chain NAV pricing and custody signals to meet compliance and accounting needs, via Chainlink NAVLink feeds for regular NAV updates.
Industry context notes ongoing tokenized funds and oracle tech developments, with references to prior Securitize and RedStone pilots for secure NAV data.
Securitize’s TSSO will map off-chain legal ownership to on-chain balances through on-chain settlement, reducing reconciliation risk for lenders.
Securitize’s transfer-agent systems and the Securitize–VanEck partnership bridge traditional fund mechanics with on-chain lending to broaden institutional DeFi liquidity without changing fund structure.
The move broadens access to RWA collateral lending and may diversify lender risk, while requiring ongoing governance and oracle risk monitoring of NAV cadence, feed reliability, and transfer reconciliation.
Since its August launch, Aave Horizon has become the fastest-growing venue for real-world assets in DeFi, surpassing $460 million in total market size.
VBILL accounting and NAV pricing are maintained via transfer-agent records and Chainlink NAVLink, enabling consistent collateral valuation and risk management.
Securitize plans to deploy its Trusted Single Source Oracle (TSSO) in the future to strengthen on-chain fund valuation verification.
Aave Horizon now accepts VBILL as eligible collateral, enabling borrowing of stablecoins against tokenized U.S. Treasuries.
VBILL, launched earlier in 2025, is the asset manager’s first tokenized fund and can now support borrowing stablecoins against VBILL holdings on Horizon.
Securitize and VanEck have added VBILL as eligible collateral on Aave Horizon, the DeFi platform for real-world assets.
The integration is powered by Chainlink’s NAVLink (and LlamaGuard NAV) oracles to provide verified, risk-adjusted net asset value for tamper-resistant pricing.
Overall, the move aims to bridge traditional finance and DeFi by making regulated assets more fluid on-chain and accessible to institutions.
