4. 4 Pectra upgrades Prague (EL) + Electra (CL) upgrades combined Expected 2024 Q4 ~ 2025 Q1 EIPs being considered of inclusion: • EIP-2537: Precompile for BLS12-381 curve operations • EIP-2935: Save historical block hashes in state • EIP-6110: Supply validator deposits on chain • EIP-7002: Execution layer triggerable exits • EIP-7251: Increase the MAX_EFFECTIVE_BALANCE • EIP-7549: Move committee index outside Attestation • EIP-7594: PeerDAS - Peer Data Availability Sampling • EIP-7685: General purpose execution layer requests • EIP-7692: EVM Object Format (EOFv1) Meta • EIP-7702: Set EOA account code
5. 5 EIP-7251 Increase the MAX_EFFECTI VE_BALANCE EIP-7002 Execution layer triggerable exits EIP-7702 Set EOA account code
6. 6 EIP-7251 Increase the MAX_EFFECTI VE_BALANCE EIP-7002 Execution layer triggerable exits EIP-7702 Set EOA account code Institutional Staking Crypto Deposit
7. 7 Institutional Staking after Pectra
8. 8 EIP-7002: Execution layer triggerable exits TL;DR • Exiting of the validator can be initiated from the execution layer. • The transaction is signed with Withdrawal Credentials Motivation and Benefit • No ways for a validator to unstake if the BLS key is lost, receiving penalties until being ejected automatically (16 ETH is lost). • Real owner of the staked asset can control over the Exit operation.
9. 9 EIP-7251: Increase the MAX_EFFECTIVE_BALANCE TL;DR • Increase maximum staking deposit amount from 32 ETH to 2048 ETH • Partial withdrawals from the deposit • Removal of Initial Slashing Penalty (Still being discussed) Motivation and Benefit • Staking service providers with large customer asset base needed to maintain many nodes. (= Total ETH staked / 32 nodes) • Partial withdrawal to rebalance customer’s ETH liquidity. • Current slashing penalty has two phases ◦ Initial Penalty = 1 ETH constant ◦ Correlation Penalty = variable based on total slashings at around the same time
10. 10 Deposit after Pectra
11. 11 EIP-7702: Set EOA account code TL;DR • Improved proposal of EIP-3074. Future-proof solution even after Account Abstraction. • You can temporarily deploy smart contract to EOA during transaction execution context. Motivation and Benefit • No EVM opcodes are added while achieving the same functionalities enabled by EIP-3074.
12. 12 …Before EIP-7702: naive approach Customer A Deposit address for A Deposit address for B Cold Exchange Frontend Wallet Exchange Backend Wallet Withdrawal Customer B External Gas Station 😢Needs gas to forward deposit
13. 13 …Before EIP-7702: forward contract approach Customer A Forward Contract A Forward Contract B Cold Exchange Frontend Wallet Exchange Backend Wallet Withdrawal Customer B External 😢ETH only 😢Expensive deploy cost 😢Not flexible 😢Contract vulnerability
14. 14 After EIP-7702 Customer A Deposit address for A Deposit address for B Cold Exchange Frontend Wallet Exchange Backend Wallet Caller Customer B External Withdrawal Any Contract ✅Flexible logic (ERC20, NFT and anything!) ✅No gas station
