4 Battle-Tested Techniques for Runtime Gas Optimization in Defi Contracts
Master EVM runtime gas optimization for DeFi contracts with lazy accounting, bitwise storage packing, calldata Yul assembly, and EIP-1153 flash accounting.
Lazy Accounting & Accumulator Patterns serve as a potent runtime gas optimization technique for DeFi smart contracts. Traditional staking, yield distribution, and token streaming systems often employ active loops to update global balances, creating scalability bottlenecks. This approach necessitates sweeping through storage slots with repetitive SLOAD and SSTORE operations, inflating costs linearly with the participant count N. To circumvent this, Lazy Accumulator Patterns employ accumulator variables that aggregate updates, storing them in a single storage slot.
This approach significantly reduces gas consumption, as updating a single slot incurs far lower gas penalties. Employing this pattern allows developers to efficiently manage large participant bases, mitigating transaction reverts caused by exceeding the Block Gas Limit.
