What is BNB Chain EIP-7702?
BNB Chain EIP-7702 refers to the adoption of Ethereum’s EIP-7702 standard on the BNB Chain, aiming to enhance account functionality, user experience, and compatibility with smart contract wallets. This significant upgrade went live with BNB Chain's Pascal Hardfork in March 2025
123.
What is EIP-7702?
Originally developed for Ethereum by Vitalik Buterin and others, EIP-7702 introduces a new concept: it allows regular user accounts, known as Externally Owned Accounts (EOAs), to temporarily act as smart contract wallets during individual transactions
45. This “temporary smart contract” capability enables features like:
- Transaction batching
- Sponsored (gasless) transactions
- Advanced programmability and privilege management for wallets
- Compatibility improvements for future upgrades and account abstraction architectures
The account reverts to “normal” after the transaction, maintaining a high degree of security while unlocking more flexible wallet behaviors.
EIP-7702 on BNB Chain
Starting with the Pascal Hardfork on March 20, 2025, BNB Chain integrated EIP-7702 to achieve the following
132:
- Enable smart contract wallets for everyday users, making it easier to onboard new users and dApp developers.
- Support gasless transactions and batch approvals, allowing users to perform multiple actions in one transaction, with optional third-party gas sponsorship.
- Enhance smart payment interfaces, DeFi, and DEX trading efficiency and user experience.
- Maintain high compatibility with Ethereum’s evolving standards, making it easier for Ethereum-native dApps and infrastructure to port over to or interoperate with BNB Chain.
All network participants, including node operators, validators, and exchanges, had to update their systems to support these changes.
Impact and Future Upgrades
- The upgrade is part of an ongoing roadmap to further reduce block times (via Lorentz and Maxwell Hardforks) and optimize transaction throughput and user experience on BNB Chain.
- The ability to batch and sponsor transactions makes BNB Chain more attractive for both end-users and dApp developers.
- The implementation of EIP-7702 is expected to further fuel BNB Chain’s already surging decentralized exchange (DEX) and on-chain activity, as well as cement its leading position in EVM compatibility and network efficiency213.
- Zyfi and other paymaster solutions are exploring EIP-7702 features for broader multi-chain gas abstraction5.
In Summary
BNB Chain EIP-7702 is a technical and usability milestone that:
- Equips regular user accounts with temporary smart contract capabilities for each transaction,
- Unlocks gasless and batch transaction features,
- Prepares BNB Chain for future EVM upgrades and innovations,
- Further strengthens BNB Chain’s competitive edge in DeFi and Web3 applications135.
