The "Bectra" upgrade of Berachain makes it the first Layer1 blockchain to activate Pectra after Ethereum.

Berachain (the first EVM-equivalent Layer 1 Blockchain adopting the Proof of Liquidity (PoL) consensus model) will launch the Bectra network upgrade on June 4. This Hard Fork has been tested in the Bepolia Testnet since May 7, introducing 7 Ethereum Improvement Proposals (EIPs), among which EIP-7702 is the core upgrade, making Berachain the first Layer 1 Blockchain to put the Pectra toolkit into production after forking from the Ethereum Mainnet.

Although some chains like Gnosis and BNB Chain selectively implemented the Pectra proposal before the Ethereum fork, Berachain's Bectra upgrade marks the first case of fully deploying all Pectra execution layer EIPs in an EVM-equivalent environment after Ethereum activation. Since Berachain adopts a unique consensus architecture, this upgrade does not involve changes to the Pectra consensus layer. More than 100 projects already on the Berachain Mainnet will directly benefit from a leap in user experience: ordinary wallets will upgrade to programmable smart accounts, liquidity stakers can exit with one click, and the data submission cost of Rollups will be lower.

User-side revolution

Bectra turns each Berachain wallet into a programmable smart account:

A single transaction can be operated in batches.

Accurate setting of consumption limits

Use the stablecoin $HONEY to pay for Gas

You can even set up periodic "subscription" payments. Previously, these features relied on customized contracts or third-party solutions.

Thanks to EIP-7002, stakers can withdraw instantly through the execution layer, and liquidity staking token (LST) providers can also exit or adjust their positions in real time.

Developers and Infrastructure Upgrade

EIP-7840 introduces low-cost Blob data, reducing Rollup submission costs and paving the way for high-throughput games, social applications, and other Layer 2 solutions.

Other upgrades (such as native BLS precompiles, historical block hash access, and fee model optimization) simplify validator operations and reduce node requirements, without the need for developers to rewrite existing contracts. More than 200 applications already available on the Berachain Mainnet can immediately utilize these features.

Team's Viewpoint

Berachain's new Chief Technology Officer Paul O’Leary (former Head of Engineering at Polygon Labs) stated:

"With every upgrade, we are committed to reducing friction for users and developers, and Bectra is the boldest step yet. Launching Bectra just weeks after the Ethereum upgrade allows developers to access the latest tools right away, accelerating project progress."

Co-founder Smokey the Bera added:

"Our goal is not only to keep up with Ethereum but also to innovate together with it, breaking through the potential of EVM chains. In the coming months, we will launch more customized improvements featuring PoL based on Bectra."

Bectra Core Upgrade Highlights

EIP-7702: Set code for Externally Owned Accounts (EOA) so that any wallet can operate like a smart account (batch transactions, preset spending limits, pay Gas with $HONEY, etc.) without changing the address.

EIP-7002: Execution layer withdrawals, liquidity stakers and LST providers can instantly exit or adjust their positions.

EIP-7840: Blob data scheduling, providing low-cost data storage for Layer 2 developers.

EIP-2537/2935/7623/7685: Native BLS precompiles, historical block hash access, and cost model optimization to enhance validator efficiency.

About Berachain

Berachain is an EVM-equivalent Layer 1 blockchain that adopts an innovative Proof of Liquidity (PoL) consensus mechanism, combining network liquidity and security. PoL allows users to directly earn network rewards by providing liquidity or participating in incentive actions, converting on-chain inflation into "fuel" for ecological applications and their users. This model aligns the interests of long-term supporters of the network with the ecology, forming a sustainable system where growth and liquidity mutually promote each other. Berachain began as an NFT project in 2021 and has now evolved into a mature blockchain ecosystem powered by the community strength of the "left/right curve."
