Gnosis Chain is an EVM-compatible Layer-1 blockchain for software engineers, targeting top-notch security, resilience, and credible neutrality, backed by a deeply decentralized network secured by over 100K validators.

Gnosis Chain will be awarding the following prizes for use of Gnosis Chain:

Most innovative dApps on Gnosis Chain:

• 🥇 $6,000
• 🥈 $5,000
• 🥉 $2,000

Plus, special prizes for innovative dApps on Gnosis Chain:

• 🤖 Best AI project on Gnosis Chain — $3,000
• 🌉 Best project on Hashi — $2,000
• 🔐 Best project on Safe — $2,000

We appreciate an impressive vision, an effective use case, and give additional points for a viable business model.

🤖 AI

Take advantage of Gnosis Chain’s decentralization and low network fees for your AI project. Demonstrate the power of AI on Gnosis Chain for a chance to win the AI bounty. Distributed labeling, training, model marketplaces, anything is possible. Be creative (don’t just build one more pay-for-GPT app).

🌉 Hashi

Hashi is an EVM Header Oracle Aggregator designed to facilitate a principled approach to cross-chain bridge security. The primary insight is that most bridge-related security incidents could have had a minimal impact if the systems relying on them had built in some redundancy. In other words, requiring messages to be validated by multiple independent mechanisms, rather than just one, is much more secure. Be creative!

• Bridge experts can create an adapter similar to Wormhole, AMB as seen here: https://github.com/gnosis/hashi/tree/main/packages/evm/contracts/adapters
• Learn more about Hashi here: https://github.com/gnosis/hashi
• Contact our team at the booth or Discord!

🔐 Safe

Build with Safe on Gnosis Chain to take advantage of "sponsored transactions". Made possible by Account Abstraction (AA), Gnosis Chain together with Safe sponsors all your users’ Safe transactions on Gnosis Chain. Use the gasless experiences that feel like web2 interactions. Utilize the Safe{Core} Account Abstraction stack on Gnosis Chain for a chance to win this bounty.

Airstack enables you to easily query and integrate any web3 on-chain data and related off-chain data into your apps.

More powerful than previous solutions, Airstack enables complex queries in GraphQL that cut across on-chain, off-chain, cross-chain, cross-project, and identity data, and enables developers to not have to host their own infrastructure to integrate and serve relevant ecosystem data to end-users.

🤖 Airstack AI enables you to query with natural language (e.g. “show me all tokens held by Vitalik.eth, images of his NFTs, and his Lens and Farcaster usernames”) — a great way to get started if you’re new to GraphQL.

🔥 New at ETH Lisbon 2023 🔥 Web3 Identity APIs: Query across ENS, Lens, Farcaster, and NFTs with a single Airstack query/response. Build the future of web3 social interoperability with Airstack.

👩‍💻 Projects building with Airstack include ZK attestation, CRM, marketing engines, ad platforms, portfolio balancers, storefronts, decentralized social, messaging apps, wallets, token-gated membership solutions, data visualization, and more. What will you build?

*🥇 Best overall use of Airstack APIs — $3,000 *🥈 2nd best use of Airstack APIs — $2,500 *🥉 3rd best use of Airstack APIs — $2,000

• 🎉 4th best use of Airstack APIs — $1,500 *🎖 5th best use of Airstack APIs — $1,000
