# PriceFeed: Two step owner transfers are safer Low/Info · Three Sigma · NFT perpetuals · 2nd January, 2024 Finding 3S-NFTPerp-L06 of the Nftperp Exchange security review. - Report: /reports/nftperp-i - Source: https://cdn.sanity.io/files/qoqld077/production/c19530de75e234ad15694b4563edb1fc9d2a3fd8.pdf --- ### Description When changing contract owner, a two step process is recommended. Using this method, first a pending owner is set, which then has to accept the role in order to become the contract owner. This prevents situations in which a mistake when setting the new owner address leads to permanent loss of contract ownership. ### Status Acknowledged --- Related findings: - [Missing priceFeedDisabled event in RedStonePriceFeedBase](https://0xsimao.com/findings/felix-price-disabled-red-stone): Felix Price Feeds - [Attacker can trigger temporary shutdown due to RedStonePriceFeedBase missing gas check](https://0xsimao.com/findings/felix-temporary-shutdown-price-gas): Felix Price Feeds
