I was not able to find anyone invoking this subject, which means that it probably is not feasible, but I need to make sure.

So is there any way one could call some endpoint from a smart contract?

CodePudding user response：

No it is not, by protocol. Accepting such thing would be a hole security. Smart contracts are meant to deal with data on the blockchain itself in an isolated and controlled environment.

Disclaimer: this is not only for solana but for most blockchains (cannot say for sure if for all of them, but it would make sense it would).

CodePudding user response：

No. calling external links on chain, requires oracle services such as Chainlink

which doesn't seem to be available on solana, as of now.
