According to @alice_und_bob, they tested Solidity smart contracts in preparation for a potential Polkadot Hub smart contracts launch they hope could arrive in about two weeks, highlighting a near-term milestone for DOT traders to monitor, source: https://x.com/alice_und_bob/status/1996976093698707580. The author reports completing local Substrate node and RPC setup, building and testing a contract, deploying it, and conducting on-chain tests, providing a concrete view of current developer workflow readiness, source: https://x.com/alice_und_bob/status/1996976093698707580. They also noted two documentation issues that required ChatGPT troubleshooting and plan to report fixes, which may reduce onboarding friction for future builders if addressed, source: https://x.com/alice_und_bob/status/1996976093698707580. Next steps cited are a simple frontend and a basic app, giving traders a practical timeline to track developer progress around Polkadot smart contracts, source: https://x.com/alice_und_bob/status/1996976093698707580.

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.
