I have a contract which uses ink_env::ecdsa_recover() for signature verification. Though all the tests are passing, I am unable to deploy it on the local node using contracts-ui.
This is the error it's throwing:
module imports a non-existent function
What am I missing?
ink_env::ecdsa_recover() uses an unstable interface of the contracts pallet. Make sure to use the substrate-contracts-node which has unstable interfaces enabled by default.
