OKEx Oracle: A Secure, Signed Price Feed for DeFi Applications

The global crypto trading giant OKEx has announced the implementation of OKEx Oracle, a secure signed price feed that serves as a source of reliable on-chain crypto prices for DeFi projects. By making OKEx Oracle available as an API that doesn’t necessitate users to be the platform’s customer, the highly liquid global exchange provides developers with access to dependable, trustworthy price data for use in their own projects.

The price feed is an important component when it comes to crypto-based financial products and trading instruments. Sometimes malicious actors exploit systemic vulnerabilities in DeFi protocols to publish erroneous information on-chain and profit from it. OKEx Oracle helps avoid such instances by creating tamperproof price feed signed by the platform itself using a secure private key, which further imparts users with the ability to verify the source as well as the integrity of such data.

Explaining the importance of OKEx Oracle, CEO of OKEx Jay Hao said, “Having access to a trustworthy price feed signed by OKEx gives DeFi projects and users the peace of mind that the data they are using is 100% accurate. Not only does this help to build reliable foundations to support DeFi further, but also helps to ensure the security of users’ assets and the longevity of the protocols they are using.”

Incidentally, the OKEx Oracle also makes use of similar OPF standards to provide reliable feed for on-chain price data.

The Compound Protocol token (COMP) was recently listed on OKEx, allowing its global userbase to trade against BTC and…
