The configuration on optimism would be 3,600 seconds (1 hour) and that of ethereum would be 129,600 seconds (36 hours).</p>\n<p>Staleness is measured by fetching the timestamp of the latest chainlink price push and comparing it to the timestamp of the current block. If the difference exceeds the configured maximum staleness parameter, the oracle would revert when called, otherwise it would return the oracle price and timestamp.</p>\n<h2 id=\"motivation\" style=\"position:relative;\"><a href=\"#motivation\" aria-label=\"motivation permalink\" class=\"anchor before\"><svg aria-hidden=\"true\" focusable=\"false\" height=\"16\" version=\"1.1\" viewBox=\"0 0 16 16\" width=\"16\"><path fill-rule=\"evenodd\" d=\"M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z\"></path></svg></a>Motivation</h2>\n<!--The motivation is critical for SCCPs that want to update variables within Synthetix. It should clearly explain why the existing variable is not incentive aligned. SCCP submissions without sufficient motivation may be rejected outright.-->\n<p>Currently the configured chainlink node does not incorporate any staleness check. However, it is considered best practice that prices are checked for staleness before being consumed (e.g. staking, unstaking and liquidation). Hence, in case the oracle is stale, all activity that touches the oracle would revert.</p>\n<h2 id=\"copyright\" style=\"position:relative;\"><a href=\"#copyright\" aria-label=\"copyright permalink\" class=\"anchor before\"><svg aria-hidden=\"true\" focusable=\"false\" height=\"16\" version=\"1.1\" viewBox=\"0 0 16 16\" width=\"16\"><path fill-rule=\"evenodd\" d=\"M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z\"></path></svg></a>Copyright</h2>\n<p>Copyright and related rights waived via <a href=\"https://creativecommons.org/publicdomain/zero/1.0/\">CC0</a>.</p>"}},"pageContext":{"id":"f3526437-8eeb-5969-b256-cd2273d63b39","frontmatter__sip":357,"__params":{"frontmatter__sip":"357"}}},"staticQueryHashes":[]}
