🖼️ Decentralized Application (DApp) Interaction with Gnosis Pay ⸺ $2,500

① $1,500 ② $1,000

Develop an innovative solution that enables seamless interaction between Gnosis Pay Account Safe users and various decentralized applications (DApps) using our Delay Module. The solution should ensure that all transactions initiated from DApps are securely queued in the Gnosis Pay delay module, providing users with enhanced control and security over their funds. Any transaction initiated from DApps needs to be queued in the Gnosis Pay delay module. Why? So that debit card transactions are not rugpulled while using a DApp (i.e. race condition).This prize aims to promote the integration of Gnosis Pay's secure infrastructure with the DApp ecosystem, empowering users to engage with DApps while maintaining robust safeguards against potential risks.

Qualification Requirements

- Needs to work with the delay module on the Safe - Needs to be deployed (Gnosis Chiado testnet or Gnosis mainnet)

📈 Yield Bearing Tokens Integration with Gnosis Pay ⸺ $4,500

① $2,000 ② $1,500 ③ $1,000

Make Gnosis Pay users earn yield on their debit card! The challenge? Users can't directly pay in yield tokens! Potential solutions include: - A solution that enables Gnosis Pay cardholders to hold and automatically convert interest-earning tokens (e.g., sDAI, wstETH) to EURe or GBPe tokens (e.g. via CoW order) whenever the balance drops below a threshold, ensuring yield and while still holding enough tokens to satisfy your grocery shopping. - A smart contract solution to provide guaranteed on chain liquidity for seamless sDAI to EURe conversions. This contract should hold a reserve of EURe and offer real-time quotes, ensuring users can hold sDAI effortlessly without manual liquidity management. The contract must include a safety feature, such as a 2-minute delay for quote adjustments or EURe withdrawals, to protect against rapid market changes. This will enable users to hold and use sDAI on their Gnosis Pay Safe Accounts with the confidence of having immediate access to EURe liquidity, streamlining the payment process on the Gnosis Pay platform.

Qualification Requirements

- Needs to work with the delay module on the Safe - Needs to be deployed (Gnosis Chiado testnet or Gnosis mainnet) - Optional: if you own a gnosis safe card you can build on mainnet but only with delay and roles module in production, beaware of any funds that you may transfer.
