HydraDX-node VS solang

This referendum, if approved, will upgrade HydraDX runtime to v14.0.0 - full details can be found at: https://github.com/galacticcouncil/HydraDX-node/releases/tag/v14.0.0 - however, some key points:

Update HydraDX (HDX) runtime upgrade required before distribution can be completed. Github

HydraDX (HDX)

It’s time. The old web https://hydradx.io has served it’s purpose, but as HydraDX and Basilisk itself grow and come closer to the launch, we need to step-up the game.

All validators, please update to 6.0 ASAP. As preparation for the genesis 3 transition, we need to upgrade chain-data and for that new node version is needed. Don't forget to stay hydrated! https://github.com/galacticcouncil/HydraDX-node/releases/tag/v6.0.0 No further action is required. Please don't purge the chain! Session keys will be persisted this time so no need to rotateKeys.

Here is a source for the first point: https://i.imgur.com/Fx24nEZ.png Kubo is a founder of HydraDX, https://hydradx.io/,

Solidity is language for smart contacts originally designed for Ethereum. If you want to execute your Solidity smart contract in a blockchain whose VM interprets WASM, then you need to compile Solidity into WebAssembly. Currently, we target Substrate (https://github.com/paritytech/substrate) and Ewasm (https://ewasm.readthedocs.io/en/mkdocs/) that need WebAssembly. This is the project's repo: https://github.com/hyperledger-labs/solang

If you really want to use solidity there is https://github.com/hyperledger-labs/solang , a solidity compiler for Solana. You will still need to learn how to interact with the Solana blockchain but you can do it in Solidity.

I see solang can compile Solidity code to Solana. Can this code be deployed to the Solana blockchain?

You could try to use https://github.com/hyperledger-labs/solang and target WASM.

It should be technically possible as I see there is a solidity to wasm compiler: https://github.com/hyperledger-labs/solang
