+You also need to update manually the version tag in `VERSION()` function and the value of the hash in the `VERIFIER_HASH()` function
+from `solidity/src/SphinxVerifier.sol`. In Move contracts the verifier hash is stored in `VERSION_1082_TESTNET` constant from `move/sources/utilities.move` source file.

+The first value can be taken directly from [Sphinx](https://github.com/argumentcomputer/sphinx/blob/dev/core/src/lib.rs#L33),
