What the etherscan equivalent for starknet is ?

I made an example using [this library with react](https://github.com/fracek/starknet-react-example), everything is working fine in development, but in production, it looks like starknet.js is throwing a type error. You can [open this page](http://starknet-react-example.vercel.app/) to see the error more in detail.

To reproduce locally:

- Clone my example repo
- Build with `yarn run build`
- Serve production build with `yarn run serve`

Based on this [Github thread](https://github.com/0xs34n/starknet.js/issues/37)

Does cross-chain bridge produce its own block? Or it only verify the blocks from A/B chain?

Hello, I am facing an issue with `starknet-devnet (v0.3.1)` . I do not manage to run RPC `starknet_addInvokeTransaction` with positional parameters; yet it works with pathfinder and other vers like `starknet_estimateFee`. It returns `int() can't convert non-string with explicit base`. It is working fine on GOERLI. I have document the case on the repo https://github.com/Shard-Labs/starknet-devnet/issues/282. Does anyone have an example of a positional request to `starknet_addInvokeTransaction` on devnet that is working? The test inside the testsuite is also using named parameters. Thank you for your help

Can I transpile any solidity version?

### *From Newton AI*
*OpenZeppelin is a collection of reusable, secure smart contract libraries for Ethereum. It provides a set of Solidity contracts that implement common contract patterns and functions, such as ERC20 token contracts and contracts for managing and securing user accounts. By using OpenZeppelin libraries in your contracts, you can benefit from the security and functionality provided by these pre-written contracts, without having to reimplement them yourself. When transpiling your contracts, the transpiler will include the code from any imported libraries, such as OpenZeppelin, in the final transpiled output.*
