Yes, it was a deliberate deactivation, and today is exactly the day it happened.
Pyth USDa/USD Feed Deactivation — April 15, 2026
TL;DR: Pyth formally deactivated Crypto.USDA/USD (your feed ID 0x3a1050...) today at 4:11 PM as part of a batch of 7 feeds. It was announced 2+ weeks ago on their developer forum.
Root Cause: Angle Protocol Shutdown
Angle Protocol — the issuer of USDa — is winding down operations. Their site now reads:
"Angle is entering its final chapter. Every USDA and EURA is redeemable 1:1. Redeem before March 1, 2027."
Pyth's policy is to sunset feeds when the underlying asset is deprecated by its issuer.
Official Announcement
Pyth posted Price Feeds Upcoming Deactivations – April 15th, 2026 on March 30, 2026, listing 7 feeds for removal including:
Crypto.USDA/USD ← your feed
Crypto.stUSD/USDA.RR ← companion Angle Protocol feed
Crypto.OM/USD
Crypto.MAG7-SSI/USD
Crypto.SXP/USD
Crypto.WOJAK/USD
Equity.US.SPLG/USD
The pyth.network/price-feeds/crypto-usda-usd page now permanently redirects to insights.pyth.network/legacy-price-feeds/crypto-usda-usd.
What You Should Do
If your system depends on this feed, you have a few options:
Remove the feed dependency — USDa is being sunset, so the price is no longer meaningful
Use a different stablecoin oracle if you need a USD-pegged reference
Handle the "feed not found" case gracefully in your code so it doesn't break anything
