- Snowbridge is a bridge that connects different blockchains and holds a lot of money.
- This proposal asks for $355,000 to keep a bug bounty program running for 12 more months.
- A bug bounty program pays people to find and report security problems in the code.
- The program is important because it protects user funds and the Polkadot ecosystem's reputation.
- Last year, over 500 reports were submitted, but only about 5 were real problems that got fixed.
- The money will pay for rewards to security researchers and for engineers to check all the reports.
- Reports will be made to the community every six months about how the program is doing.
- The program will use the HackenProof platform again, where it was hosted before.

Snowbridge 2026/2027 Bug Bounty Proposal

- Snowbridge is a bridge that connects Polkadot to Ethereum and other networks.
- It helps move money and users between these networks without needing trust.
- In the last year, it handled about 21,000 transfers and $10-20 million each month.
- It made 14,100 DOT for the Polkadot Treasury from fees.
- The team made it cheaper to use, cutting fees by up to 90%.
- Now it also works with Base, Optimism, and Arbitrum networks.
- This proposal asks for $364,200 to keep the bridge running for the next 12 months.
- The money will pay for 2 engineers and important computer costs.

Snowbridge 2026/2027 Maintenance Proposal

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!

Polkadot Staking Dashboard: Protocol-Aligned Development

- A new data structure called Merkle Mountain Belt (MMB) is proposed to improve blockchain efficiency.  
- MMB helps save money (around $1 million per year) for Polkadot users, especially in bridges.  
- It works better than older structures for recent data (1 minute to 1 day old).  
- The team will make a research paper and a Rust library by June 2026.  
- Funding requested: $340,198 upfront, plus extra DOT if savings exceed costs.  
- The team includes experts with Polkadot experience.  
- Changes from the last proposal include lower costs and simpler goals.  
- More details are available in links provided.
