Chipping in on behalf of Golem, we looked into EIPs (thanks @boris for encouraging us) - The EIPs that interest us the most:
Account abstraction
- EIP-101: Serenity Currency and Crypto Abstraction
- EIP-86: Abstraction of transaction origin and signature
EVM improvements
- EIP-1014: Skinny CREATE2 (solves token wrapper transactions race condition issue)
- EIP-210: Blockhash refactoring (optional, you have to review it)
Sharding!
- No EIPs for it, but we want it
