Substrate Framework-Based

The parallel chain shall be built upon the substrate framework and can execute contracts developed for the Substrate framework-based blockchains. These parallel chains will support smart contracts written in Rust, which means smart contracts written for Vine Mainnet will also work on Substrate framework-based parallel chains.

This implies if you want to use your dApp on a parallel chain, it's just that you need to deploy your smart contract to this parallel chain. It looks, feels, and acts just like Mainnet—you write contracts in Rust and interact with the chain via the parallel chain RPC.

Because parallel chains are Substrate-based, they are considered a useful scaling solution for Substrate-native dApps. With your dApp on a parallel chain, users can enjoy lower gas fees and faster transactions, especially if Mainnet is congested.

However, as explained previously, using a parallel chain involves significant trade-offs. Each parallel chain is responsible for its security and doesn't inherit Vine security properties. This may increase the possibility of malicious behavior, which can put your user's funds at risk.
