Optimism: Major outage affecting swap routes — resolved

Summary

CryptoRoute's route monitoring observed major outage conditions on Optimism. The incident is resolved; this page records the affected routes, the observed impact and the timeline.

What happened

CryptoRoute continuously probes the health of its swap routes. On Sun, Jul 19, 2026 11:46 PM UTC, our monitoring flagged Optimism as major outage based on a drop in synthetic quote success and/or elevated latency.

Update: the incident was resolved on Mon, Jul 20, 2026 4:16 AM UTC and Optimism returned to operational.

Why it matters for swaps

While the incident was active, routes touching Optimism may have quoted more slowly, failed more often, or been temporarily unavailable. Swaps are non-custodial and refundable, but it is always worth checking status before sending funds.

Affected routes

• USDC → USDC — major outage (100% quote success (n=12, last 90m))

Alternatives

These routes that also touch Optimism were operational at the time of writing — they share the same network, so check the live status before using them:

• USDT → USDT

The safest option is usually to wait for status to return to operational, or to use a route that avoids the affected network entirely (a different destination chain or asset).

What to check before you swap

• Confirm the current status on the Optimism status page.

• Verify your recipient address is correct for the destination network.

• Do not resend a transaction while a previous one is still processing.
