Layer 2 Grants Wishlist

The Ethereum Foundation is interested in the following things, but don't let this restrict your creativity.

R&D aimed toward cross-rollup transaction execution (both synchronous and asynchronous)
Develop technical wallet standards to aid L2 support
New transaction abstraction and aggregation techniques, i.e. allow using BLS or another crypto instead of ECDSA.
Research solutions around liquidity fragmentation on L2s
Research on trustless bridging techniques
Research and define metrics for better understanding and comparing L2 activity – e.g. transactions, TVL, etc."
Research and define security metrics to help users compare L2’s
Better compression for rollups
Ideas around Account Abstraction
Cross-chain MEV
Enabling new EVM functionality on L2s prior to L1
Layer 2 Light clients
Hardware/infrastructure design for ZK efficiency
- Bridges and Zero Knowledge Proofs
Experimental virtual machines / ZK-friendly virtual machine
Sequencer privilege and MEV
Rate limit execution and 1 honest party assumption research

Analytics

Status dashboards to monitor network health.
Develop and Design an Ethereum panel/explorer (main chain and all chains "secured by Ethereum")
Analytics Dashboard that can provide useful data insights on layer2’s
Data visualization can help people understand different layer2 aspects (gas costs, security, potential savings over a longer timeframe etc.)
An open-source block explorer that supports all rollups (the ability to drill into the data would be a plus)
Research and analysis of L2 activity providing novel insights
