The advantage of Wasm is that it allows for more flexibility, speed, and potentially lower execution costs compared to EVM, especially in the context of Polkadot's multi-chain architecture

 - [**EVM-compatible contracts**](/develop/smart-contracts/evm/parachain-contracts/){target=\_blank} - contracts are written in languages like Solidity or Vyper and executed by the Ethereum Virtual Machine (EVM). The EVM is widely standardized across blockchains, including Polkadot parachains like Astar, Moonbeam, and Acala. This compatibility allows contracts to be deployed across multiple networks with minimal modifications, benefiting from a well-established, broad development ecosystem
 - [**PolkaVM-compatible contracts**](/develop/smart-contracts/evm/native-evm-contracts/){target=\_blank} - contracts are written in languages like Solidity or Vyper and executed by the PolkaVM. This compatibility provides a seamless transition for developers coming from EVM environments while also enabling interactions with other Polkadot parachains and leveraging Polkadot's interoperability
