In the latest version of the package web3py 6.0.0, several method names were deprecated such as solidityKeccak, toChecksumAddress and so on. This should be changed to the actual method names.

skalenetwork/internal-support#27

Add ability to execute multiple calls in one transaction.

when trying to send transactions to precompiled via multisig we found out that marionette is not able to do it, probably because of specifics of how precompiled should be called. need to fix it to enable this feature https://skalelabs.atlassian.net/browse/SKALE-4810

┆Issue is synchronized with this Jira Bug

It is proposed to combine all the current predeployed contracts into one repository (only .sol sources and probably versions). The purpose of this repository will only be contract updates.

Pros:

1. Simplifies the update procedure, since it will be possible to update all the predeployed contracts on the chain at once. In the future, the number of chains may increase significantly and updating each individual contract on each individual chain may cause difficulties.
2. Saves us from having to copy paste almost the same code for updating into all predeployed contracts.

Cons:

1. Increases the chance that the update procedure will be unsuccessful, since we will try to update all contracts in one transaction.
