Chainlink Launches CustodySync With Anchorage Digital

October 26, 2026

Chainlink launched CustodySync on Oct. 26, 2026, a product meant to let institutions borrow in decentralized lending markets while their crypto stays with a qualified custodian. According to Chainlink's announcement, Anchorage Digital Bank, N.A. — the first federally chartered digital asset bank in the United States — is the official launch partner. The Defiant reported that shared price data is used to align loan valuations, while Anchorage retains the collateral and manages margin and liquidation.

What happened

CustodySync is designed to keep a custodian's systems and a DeFi lending market aligned across a loan, from deposit and borrowing through repayment and liquidation. Chainlink says the qualified custodian retains control of client assets, and both sides act on the same verified data.

When an institution deposits collateral, Chainlink Proof of Reserve publishes the custody balance onchain. A transfer-restricted receipt token, whose supply tracks those assets, is posted to the lending market. Chainlink says the receipt carries no claim on the underlying assets outside that integration. Borrowed funds move to the client in one transaction, and borrows, repayments, and interest are written back to the custodian's records.

The lending market reads Chainlink Data Feeds onchain. Data Streams send the same prices to the custodian's offchain systems, so both sides calculate loan-to-value from one source. If a loan crosses its liquidation threshold, an appointed collateral agent sells through its own process. CustodySync records the committed proceeds onchain, with final settlement intended to complete in a single transaction.

Chainlink's Runtime Environment is described as the layer that watches the custodian's collateral system, carries out authorized onchain actions, and writes loan activity back. Standardized contracts, designed by Chainlink and deployed by the lending market or a risk curator, are where those actions run.

Anchorage is the first qualified custodian to build with CustodySync. Its Atlas Collateral Management product is meant to act as collateral agent for lending protocols, in a tri-party structure familiar from traditional markets. Nathan McCauley, Anchorage Digital's chief executive, said institutions "should not have to choose between qualified custody and onchain liquidity."

Why it matters

Many institutions must keep assets with a qualified custodian because of regulation, investment mandates, or internal rules that limit direct exposure to smart contracts. That requirement has left much custodied crypto outside DeFi lending.

Chainlink cites roughly $700 billion in digital assets under custody, a figure it attributes to Standard Chartered, and says that is less than 0.5% of about $250 trillion in traditional assets under custody. It also says DeFi lending markets hold more than $80 billion in deposits and over $30 billion in active loans, with the loan figure taken from DefiLlama. Those are cited market sizes, not capital already connected through CustodySync.

The operational risk Chainlink highlights is mismatched records. If a custodian and a protocol value the same position differently, or if updates lag, one side may liquidate a loan the other still treats as healthy, or delay a sale until collateral no longer covers the debt. Shared prices and an onchain reserve record are meant to narrow that gap. For protocols, the stated benefit is borrowing demand from clients who will not move assets out of custody. For custodians, Chainlink argues a shared standard can avoid a custom build for every market.

What's next

Chainlink presents CustodySync as infrastructure other qualified custodians could adopt. The launch post does not name a specific lending protocol as live. Clients and venues will still need to confirm supported assets, fees, and which functions a custodian has enabled.

Chainlink Labs states that it does not hold, custody, or transfer assets, and that it is not a lender, borrower, or loan counterparty. It also notes that features may vary by custodian and that not all of them may be available at Anchorage Digital Bank. Comments about how far the model might scale toward traditional custody markets are Chainlink's expectations, not completed results. Odaily and Chainlink Today reported the same core design: restricted receipts as collateral, shared pricing for loan-to-value, and a designated agent handling a sale if liquidation is triggered.
