Fusaka Upgrade Features
The Fusaka upgrade activates several execution-layer features on the Berachain EVM:- EIP-6110 (in-payload deposits): Deposit requests are included in execution payloads and consumed by consensus in the same block, replacing the eth1 follow-distance deposit queue. Berachain processes deposits per block and emits a chain-specific deposit event for tooling that monitors stake flows.
- EIP-7951 (P-256 precompile): Native verification of passkey and hardware-key signatures, usable for smart-account flows backed by WebAuthn, Apple Secure Enclave, Android Keystore, and HSMs.
- EIP-7939 (CLZ opcode): A faster bit-math primitive that returns the position of the leading set bit in a single opcode.
- EIP-7823 & EIP-7883 (MODEXP repricing and bounds): Repriced modular exponentiation, with an input-size bound (capped at 8,192 bits) that rejects oversized arguments outright.
- Code-size limits (EIP-7954 aligned): Expanded contract code and initcode size limits (32 KB and 64 KB, respectively), raising the ceiling on what a single contract can deploy.
- EIP-7934 & EIP-7825 (Size caps): Defense-in-depth caps on block size (10 MiB) and per-transaction gas (16.7M gas), sized well above current usage.
EIP-7702 — Native Account Abstraction
EIP-7702 allows externally owned accounts to temporarily behave like smart contracts within a single transaction. This unlocks batched calls, gas sponsorship, and other account-abstraction patterns without deploying a separate contract wallet.- Basics — understand the fundamentals
- Batch Transactions — combine multiple calls into one transaction
- Gas Sponsorship — let a third party pay for gas
EIP-5792 — Wallet Batching Capabilities
EIP-5792 introduceswallet_sendCalls, enabling applications to request wallets to process batches of on-chain write calls and check their status.
