Archax adopts Chainlink to support tokenized Treasury collateral held 1:1
Key Facts
Archax announced on 19 October 2026 that it had adopted Chainlink technology to support the use of tokenized U.S. Treasuries as programmable collateral, linking its GOVY product to blockchain-based finance applications. The company said the integration aims to provide the data needed for lending, collateral and treasury management applications, the uses it identified in its adoption announcement. Target users include banks and asset managers, alongside decentralized finance users served by these applications. The integration relies on Chainlink Data Streams, which provides low-latency market data off-chain while allowing it to be verified on-chain. Archax describes the purpose of adopting the technology as enabling tokenized Treasury bills to be used "as programmable collateral." According to the company, GOVY gives eligible investors direct, legally enforceable exposure to short-term U.S. Treasury bills. The underlying assets backing that exposure are held 1:1 under regulated custody arrangements, according to Archax's announcement.
The service's technical architecture uses a pull-based data model, according to Chainlink's technical documentation. This design involves requesting data under that model, while the service allows the market data it supplies off-chain to be verified on the blockchain. Chainlink also says the service enables stale data detection, a function intended to support tokenized asset applications. The detection mechanism covers data received outside market hours, linking on-chain activity to conditions in traditional markets. The company says the aim is to "maintain accurate on-chain behavior that reflects traditional market conditions." The announced technical features thus address the timing and status of data, alongside low-latency delivery and verifiability. These functions form part of the data service Archax has adopted for tokenized collateral applications.
GOVY's structure gives investors direct beneficial ownership of specific Treasury bills, according to the product's official website. The website describes this relationship as "direct beneficial ownership of specific Treasury bills," with the token recording the associated rights on the blockchain. The product is restricted to professional investors, according to the eligibility requirement published on its website. When the bills mature, the rollover mechanism reinvests the proceeds in the next Treasury bills, in accordance with the investor's instructions. Reinvestment takes place automatically at each maturity, according to the website's explanation of how the product works. The website describes the mechanism as "mechanical, with no discretionary decisions," specifying how the rollover is executed. This arrangement links continued investment to the investor's instructions and the sequence of bill maturities, with beneficial ownership rights recorded as tokens on the blockchain.
The integration announcement follows a plan announced by tZERO and Archax on 23 June 2026 to distribute GOVY to qualified purchasers in the United States. The announcement identified tZERO's brokerage and custody infrastructure as the channel for this distribution. The plan made the channel subject to tZERO's due diligence and final approval. The announcement said distribution would be "subject to tZERO's due diligence and final approval," setting out the conditions for proceeding with the U.S. channel. On networks, the June announcement said the product's initial issuance covers Ethereum, Hedera and Stellar. These networks constitute the scope of the initial issuance presented in the announcement as part of the plan to make tokenized Treasury bills available. The announced next step includes plans to support additional blockchain networks.
