When it comes to message cancellation (L1 -> L2) you can cancel a message in the case that:
- There is any kind of censorship on StarkNet (sequencer skipped your tx)
- The L2 contract's `` function flow has an assert that fails

Is this correct? Am I missing any other situations where message cancellation would/wouldn't work?

Can you explain about cancellation (L1 -> L2) in StarkNet (sequencer)?

# Is Kakarot zkEVM a blockchain?

Does Kakarot have its own consensus, finality, commitment to L1, blocks, etc.?

Is Kakarot zkEVM a blockchain?

Can we deploy kakarot zkEVM on StarkEx and then run multiple solidity dapps on top of it?

Another question I have is:

**What's easier, adapt the create2 trick in Solidity then transpile or transpile first then adapt in Cairo?**

---

### *From Newton AI:*

*"Create2" is a feature in Solidity, the programming language used to write smart contracts for the Ethereum blockchain. It allows the creation of new contract accounts using a deterministic algorithm, rather than having to send a transaction to create the contract like with the original "create" function. This can be useful in certain situations, such as when creating a contract that is intended to be deployed at a specific address.*

*Transpiling is the process of converting code written in one programming language into another language. This can be useful if a piece of code needs to be run on a platform that only supports a different language, or if it is desired to use a different language's features or syntax.*


Did you change the factory/create2 part (to compute pool addresses)?

Hi all,

Am planning on starting a mainnet node and running it in a docker container as per these instructions:
https://github.com/eqlabs/pathfinder/#running-with-docker

My question:
I am already running a full Ethereum node on my server. I this case, can I set the  PATHFINDER_ETHEREUM_API_URL parameter to my node's endpoint, i.e. 127.0.0.1:[eth node rpc port]?

Thx.

How do I connect my DAPP to Starknet testnet using starknetjs?

What are Event Indexers in Cairo lang? What is a StarkNet indexer?
Can you explain more about how it work and is there any difference between StarkNet indexer and Solidity once?

What are Event Indexers in Cairo lang? What is a StarkNet indexer?

Yes! Warp will try to find the path to node_modules and pass the correct flags to the solc compiler. If your openzeppelin or other library contracts are located somewhere else you can the base-path and include-path flags to make sure your imports work. See https://docs.soliditylang.org/en/v0.8.17/path-resolution.html#base-path-and-include-paths for the relevant docs.


I'm currently trying to transpile an ERC 721 contract I have that uses openzeppelin libraries, is that possible?
