According to @alice_und_bob, the Polkadot SDK is positioned as the best stack to build L1s, L2s, and L3s, enabling teams to launch an L1 in minutes with EVM functionality out of the box; source: https://twitter.com/alice_und_bob/status/1955412892708377039. Polkadot SDK documentation shows EVM compatibility via the Frontier stack and provides starter node templates for bootstrapping new chains, allowing Solidity smart contracts to run on Substrate-based networks; sources: https://docs.substrate.io https://github.com/paritytech/frontier https://github.com/substrate-developer-hub/substrate-node-template.
