OpenSquare is a team that makes tools for Polkadot to help people use it better. They have four main tools: Subsquare, Statescan, Dotreasury, and Off-Chain Voting. They are asking for support to keep their work going in 2026.

Here’s what they plan to do:
- **Keep everything running:** They will pay for servers and other services, which costs about $468 each month.
- **Maintain their tools:** They fix bugs, update the tools, and help users with questions.
- **Add new features:** They want to make Subsquare better by showing how votes change, adding translations, and helping with treasury projects.
- **Improve other tools:** They will update Statescan to show staking info and add new voting options to Off-Chain Voting.

This support will help OpenSquare continue making Polkadot easier and more fun for everyone to use!
