Chainlink introduced CustodySync on October 26, 2026, a solution designed to connect qualified custodians with decentralized finance lending markets. The system enables institutional clients to access onchain borrowing while their digital assets remain securely held in regulated custody.

Anchorage Digital Bank serves as the official launch partner. Through the arrangement, institutions can use assets under custody as collateral for DeFi loans without moving those holdings into smart contracts or other non-custodial environments.

How CustodySync Operates

CustodySync synchronizes custody records with lending market activity across the full life of a loan. Chainlink’s Proof of Reserve publishes custody balances onchain. A transfer-restricted receipt token then represents the collateral inside the lending protocol. That token carries no independent claim on the underlying assets outside the specific integration.

Borrowed funds flow directly from the lending market to the borrower. Chainlink’s Runtime Environment coordinates authorized actions and updates the corresponding custody records. Matching price data reaches both the custody and lending systems through Chainlink Data Feeds and Data Streams.

When a position hits its liquidation threshold, an appointed collateral agent manages the sale process. CustodySync records the committed proceeds onchain before final settlement occurs. Features available through the system may vary by custodian.

Addressing Operational and Risk Gaps

Custody platforms and DeFi lending markets were not originally built to operate together. Without coordination, the two systems can produce inconsistent loan valuations. That mismatch risks premature or delayed liquidations that affect both borrowers and lenders.

CustodySync aims to reduce those inconsistencies by keeping balances, prices, and loan status aligned. For custodians, the design supports faster deployment and lower operational overhead through custodian-managed controls. Lending markets receive independent, verifiable data and a more consistent risk framework.

Anchorage’s Atlas Collateral Management product forms part of the initial implementation. Atlas monitors positions continuously, issues margin calls according to agreed thresholds, and coordinates liquidations through trading desks when required. Borrowers and lenders first establish bilateral agreements that set loan-to-value ratios, cure periods, and response protocols before funding occurs.

Scale of the Opportunity

DeFi lending markets currently hold more than $80 billion in total value. At the same time, approximately $700 billion in digital assets sits under institutional custody. Traditional assets under custody total roughly $250 trillion, placing digital holdings at less than 0.5 percent of that figure.

The gap indicates substantial capital that remains idle relative to available onchain liquidity. Institutions have long sought ways to put custodied digital assets to work while meeting regulatory and operational requirements. CustodySync positions itself as infrastructure intended to remove the need to choose between those priorities.

Anchorage has previously enabled similar access for Bitcoin collateral through an arrangement with the Spark lending market. In that setup, Anchorage acts as collateral agent, handling monitoring, margin calls, payments, and liquidations while assets stay in qualified custody. Multiple institutional borrowers have already drawn loans under that structure.

Context and Next Steps

The CustodySync launch arrives ahead of Link:NYC, scheduled for October 29, 2026. Chainlink has framed the product as the first in a series of announcements expected to showcase further developments and partnerships focused on financial applications.

Anchorage Digital Bank operates under a federal charter and is supervised by the Office of the Comptroller of the Currency. The bank has also expanded institutional pathways into other onchain activities, including staking and selected lending products, while keeping assets inside its custody platform.

Whether CustodySync gains broader adoption will depend on its ability to deliver the reliability and risk controls institutions require. The solution seeks to let qualified custodians offer their clients direct routes into DeFi lending markets without compromising the security and compliance standards that define regulated custody.
