Stablecoin issuer United Stables turns to Chainlink oracles as $1bn supply mark passes
United Stables adopts Chainlink Data Feeds and Proof of Reserve for its U stablecoin after a security review flagged oracle risks.
United Stables has adopted Chainlink’s Data Feeds and Proof of Reserve infrastructure for its U stablecoin, which has now surpassed $1 billion in circulating supply, as issuers of dollar-pegged tokens face mounting scrutiny over the reliability of the pricing and collateral verification systems underpinning decentralised finance.
According to the firm’s announcement, the integration followed an internal security review that identified fragmented liquidity, unverified pricing and bridge vulnerabilities as structural weaknesses across the legacy oracle infrastructure it had previously relied upon. U, which is native to BNB Chain, is reported to be logging more than $2.5 billion in daily trading volume.
Verified collateral for a token backed by cash and rival stablecoins
Chainlink’s Proof of Reserve service will give counterparties on-chain cryptographic confirmation of U’s backing, which comprises cash alongside USDC, USDT and USD1 held in segregated accounts. Chainlink Data Feeds will meanwhile supply decentralised pricing data across more than 20 lending protocols connected to the stablecoin.
United Stables chief executive Athena said the integration would let institutional partners and DeFi protocols “access verified pricing data and independently confirm U’s collateral around the clock.” A Cross-Chain Interoperability Protocol (CCIP) integration is also planned, though it is not yet live, which would extend U’s reach across additional blockchains.
The deal was confirmed by Chainlink’s official account, which described United Stables as choosing the network because it “provides the institutional-grade security required for global scale.”
LINK price steady despite the utility boost
LINK itself showed a muted reaction to the news, trading near $8.60 to $8.70, down roughly 1.5% over 24 hours, according to Coinspeaker. The modest move suggests markets have yet to fully price in the longer-term implications of Chainlink cementing itself as settlement infrastructure for a billion-dollar stablecoin, rather than the immediate token-level catalyst traders often look for.
For an audience of institutional allocators and regulators, the more consequential detail may be structural rather than price-related. Stablecoin issuers are under growing pressure, from both counterparties and supervisory bodies, to demonstrate that reserves are verifiable in real time rather than attested periodically. Proof of Reserve mechanisms of the kind Chainlink provides are increasingly positioned as a partial answer to that demand, offering continuous, cryptographically verifiable collateral checks rather than point-in-time audits.
The move also illustrates how oracle networks are becoming embedded not just in token pricing but in the compliance and risk architecture that stablecoin issuers must present to institutional partners as adoption scales. With U’s daily volume already exceeding $2.5 billion and its supply crossing $1 billion, the stakes attached to the reliability of that underlying data infrastructure rise correspondingly.
