Demo Day Cancellation Notice
Due to time constraints and the high volume of strong submissions, we will not be hosting a Demo Day for the @Polkadot Solidity Hackathon.
👉 Instead, all projects have been carefully reviewed and evaluated by our judging panel, and winners were selected based on overall quality, innovation, and execution.
📄 The full list of winning projects and prize breakdown will be shared in the next post.
We truly appreciate the effort and dedication from all participating teams 🙏

The first Polkadot Solidity Hackathon, organized by @openguildwtf in partnership with @Web3foundation, has concluded.
More than 260 teams and 850 hackers participated, building with Solidity on Polkadot Hub across EVM and PVM environments.
We thank all participants for their contributions. 🧵

Our BUIDL for the @Polkadot Solidity Hackathon: Civyx
Not just another DeFi protocol —
but a reputation-powered trust layer for the entire ecosystem.
Instead of fixed rules, Civyx introduces:
→ dynamic collateral (CivUSD)
→ cross-chain reputation (via XCM)
→ private identity (no KYC, no middlemen)
This is the missing piece between activity and capital efficiency.

Massive shoutout to @openguildwtf and @Web3foundation for pushing innovation in the Polkadot ecosystem 🤝

@openguildwtf Polkadot Solidity Hackathon - EVM and @OpenZeppelin Tracks
Built a medical emergency funding system — focused on fast, transparent access to funds when it matters most from any location.
Real-world problem. Real urgency. Real learning.

Shipped a public common good at the @Polkadot Hackathon organised by @openguildwtf.
A no-code vesting tool for Polkadot.
No more manual extrinsics or transaction complexity.
Just connect your wallet, view your vesting schedules, and claim tokens in one click, all on-chain, and much more.
Built for builders, teams, and anyone dealing with vesting.
Stay tuned for more updates.

Big thanks to the devs, organizers @openguildwtf @Web3foundation , and community behind the Polkadot Solidity Hackathon 2026!
We built ChopDot, a Web3-native shared expense and settlement app with smart contract EVM capabilities: dorahacks.io/buidl/41088
Shoutout to @TheMrScrooby, my partner in crime on this one 🤝
And good luck to all the other teams. A lot of great stuff got built here. 🚀

Just submitted my solo entry for the Polkadot Solidity Hackathon 2026: a DEX Analytics Dashboard on Hub Testnet.
It includes a constant-product AMM with mock stablecoin pairs, plus views for slippage on swaps, LP PnL (impermanent loss + fees), trade history table, volume/price charts, and a client-side price prediction model.
Solidity contracts deployed with Hardhat and Remix after dealing with testnet RPC instability and gas estimation issues. The shared security and low testnet fees made testing straightforward.

Also - if you're following the @Polkadot Solidity Hackathon by @openguildwtf and @Web3foundation:
Relaycode Studio is our entry. Dual track (EVM + PVM).
We definitely need more developer tooling for pallet-revive and Polkadot Hub
Check out our BUIDL: dorahacks.io/buidl/40980
If you think Polkadot needs better dev tools, show some love 🤙
