Pyth Network’s API overhaul threatens to freeze unpatched smart contracts across 300 DeFi protocols

Infographic showing who had to act for Pyth

Crypto value oracle Pyth Network missed its documented 16:00 UTC cutover deadline on Aug. 26, including a brand new requirement for builders who name its Hermes price-delivery service immediately: their requests now want an API key.

Under Pyth’s migration information, individuals who use a protocol that already integrates the oracle do not want to take direct motion.

Pyth documented that the existing hermes.pyth.community handle would redirect to its upgraded backend, with authentication required after the deadline. Developers may additionally transfer immediately tohttps://pyth.dourolabs.app/hermes, passing the important thing as a bearer token or SDK entry token.

Pyth mentioned the routes and response shapes didn’t change.

Pyth’s Aug. 26 cutover required direct Hermes callers and Sui integrators to replace authentication or configuration, whereas protocol finish customers wanted no motion.

Where incomplete Pyth migrations can fail

Pyth’s upgraded Hermes endpoint serves payloads supposed for the upgraded Pyth Core contract. The information warns that altering the endpoint with out altering the contract technology, or doing the reverse, can go away an software unable to confirm value updates.

An software with out the required key could not full authenticated Hermes requests, whereas one with mismatched endpoint and contract settings can obtain knowledge that its on-chain integration won’t confirm.

In a pull-oracle design, both downside can cease the applying’s price-update transaction from finishing till the configuration is corrected.

Sui integrations did not have the automated package-swap path as a result of purposes reference the Pyth bundle by object ID, which the Pyth DAO could not substitute for them. In sensible phrases, Sui builders had to replace each the consumer used to fetch value knowledge and the on-chain Move bundle dependency.

Pyth’s Sui-specific guide required them to level SuiPriceServiceConnection on the upgraded Hermes endpoint with an entry token and transfer the oracle dependency in Move.toml to the brand new bundle revision.

It additionally mentioned purchasers whose constructor couldn’t settle for an accessToken had been outdated.

A stay DefiLlama oracle table mapped Pyth to 316 protocols and about $2.7 billion in whole worth secured.

That determine is dynamic, and the chosen view contains borrowed values and settings that may rely the identical publicity greater than as soon as, serving as a proxy for worth inside protocols that depend upon Pyth.

As of that post-deadline examine, there was no confirmed outage, stale-price occasion, lack of funds or official affirmation that each redirect and migration had accomplished cleanly.

The fast check was whether or not direct callers may authenticate and whether or not their endpoint, SDK, and on-chain contract technology matched.
