 ## Overview
 
-Subtensor now supports smart contract functionality through the integration of `pallet-contracts`, enabling developers to deploy and execute WebAssembly (WASM) smart contracts on the network. Contracts are written in [ink!](https://use.ink/), a Rust-based embedded domain-specific language (eDSL) for writing smart contracts on Substrate-based chains.

For compatibility, WASM contracts can also be compiled from Solidity using [Solang](https://github.com/hyperledger-solang/solang).
