Chainlink introduced CustodySync on October 26, 2026, with Anchorage Digital Bank as its first custodian partner, according to Crypto.news. The product lets institutions borrow from decentralized lending markets against assets that remain in qualified custody rather than being moved onto onchain contracts.
Anchorage is using its Atlas Collateral Management product for the arrangement. “Institutions should not have to choose between qualified custody and onchain liquidity,” Anchorage chief executive and co-founder Nathan McCauley said in the announcement.

Key facts
- Chainlink’s Proof of Reserve publishes custody balances onchain, while a transfer-restricted receipt token stands for the collateral inside the lending market; the token carries no claim on the underlying assets outside that integration.
- Chainlink’s Runtime Environment coordinates authorized actions and custody-record updates, and Data Feeds and Data Streams send matching prices to both systems.
- When a position reaches its liquidation threshold, an appointed collateral agent handles the sale, and CustodySync records committed proceeds onchain before final settlement.
- Anchorage has an existing arrangement with Spark that lets institutions borrow against Bitcoin held at the bank; multiple borrowers had drawn loans, but Anchorage did not disclose their identities or the total amount.
- Coinpedia reported that DeFi lending markets hold more than $80 billion, against roughly $700 billion in digital assets under custody.
Borrowed funds go straight to the borrower
In Chainlink’s design, borrowed funds move directly from the lending market to the borrower rather than passing through the custodian. The custody side and the lending side see the same prices throughout the loan’s life, which the company says removes the discrepancies that can lead to premature or delayed liquidations.
Anchorage’s Atlas Collateral Management Manual, dated April 28, sets out the framework. Borrowers and lenders sign bilateral agreements covering eligible assets, loan-to-value thresholds, cure periods and required responses before any funding is released, and the borrower then deposits collateral into a segregated vault or wallet. Atlas monitors positions around the clock. When a threshold is breached, responses can include notification, partial liquidation, full liquidation, or transfer of collateral to the secured party. A critical threshold can trigger immediate action unless cure-period protection is configured, and the manual says liquidations are coordinated through Anchorage’s trading desks. Chainlink noted that available features may differ between custodians.

Anchorage’s lending and staking routes
Anchorage’s work with Spark gave institutions a way to borrow against Bitcoin without removing it from custody; the bank acts as collateral agent there, monitoring loan-to-value ratios, payments, margin calls and liquidations through Atlas. Anchorage said that structure serves borrowers unwilling to put their collateral fully into onchain lending contracts.
Other integrations sit alongside it. On October 8, Crypto.news reported that Anchorage had joined Sui’s Hashi launch coalition, which announced more than $500 million in capital commitments from more than 20 launch partners for a phased mainnet rollout. A September 11 announcement from Frgmnt described institutional access to fUSD and the sfUSD staking product through Anchorage’s custody infrastructure on Base. Anchorage also integrated Lido staking on July 2, letting clients mint and burn wrapped staked Ether inside its custody platform.
Coinpedia put the CustodySync opportunity in market terms, noting that digital assets make up less than 0.5% of the roughly $250 trillion in traditional assets under custody. Those figures come from Coinpedia; Crypto.news’s report did not include market-size estimates.
Why it matters
Institutional holders have long kept collateral in regulated custody precisely because lending contracts demanded the assets be moved. CustodySync’s model keeps ownership records at the custodian and puts a restricted representation token into the lending market instead, so the underlying asset never leaves the bank. Custodians get a deployment route with their own controls, lending markets get independent price data, and borrowers can put idle holdings to work without a second custody setup.
What to watch
Chainlink said features may vary by custodian, so the next signal is which banks and custodians adopt CustodySync and whether borrower demand follows. Anchorage’s existing Spark book, with undisclosed borrowers and volume, is the closest read on whether institutions actually draw against custodied collateral.
