Etherspot’s Skandha Bundler Now Supports ERC-4337 EntryPoint v0.8.0

Account Abstraction (AA) has quickly become a game-changer for enhancing user experiences in Web3. The implementation of ERC-4337 brought essential new components into the ecosystem, such as Bundlers, Paymasters and the crucial EntryPoint contract. If you’re still exploring AA and its underlying architecture, we recommend checking out this detailed article. Recently, the ERC-4337 team announced a significant update: EntryPoint v0.8.0. Let’s dive into what EntryPoint is and explore the latest improvements in version 0.8. What exactly is the EntryPoint contract? Think of EntryPoint as the heart of the ERC-4337 ecosystem. It’s the core contract responsible for processing UserOperations (UserOps), handling verification and execution logic seamlessly. EntryPoint acts as a singleton, meaning only one instance should exist on each blockchain, to ensure consistency and efficiency. Key Features of the EntryPoint Contract: Simplified Transactions: Execute transactions with smart contract-level logic, enhancing the user experience. Boosted Security: Introduces robust verification layers and conditions, making interactions on the blockchain safer. Developer Freedom: Enables developers to build advanced dApps by embedding complex transaction logic directly within user accounts. What’s new in EntryPoint v0.8 compared to v0.7? EntryPoint v0.8 brings crucial upgrades and essential fixes: 1. Native Support for EIP-7702 Authorizations: Integrates delegation mechanisms directly into EntryPoint. Includes delegation addresses in UserOperation hashes. Verifies delegation addresses during processing. Supports the eip7702Auth parameter in eth_sendUserOperation. Adds an AUTH category within ERC-7562 validation rules. 2. ERC-712 Based UserOperation Hash and Signatures: Adopts ERC-712 standards to ensure compatibility with external signers like hardware wallets. 3. Optimized Unused Gas Penalty: Removes the 10% penalty if the unused gas is below 40,000 units, improving efficiency without affecting network security. 4. Introducing the Simple7702Account Contract: Adds a minimalist, fully audited smart contract wallet that complies with ERC standards such as ERC-165, ERC-721, ERC-1155, ERC-1271, and ERC-4337 v0.8. 5. Enhanced ERC-7562 Validation Rules: Allows CREATE/CREATE2 opcodes during deployment. Permits storage access for all staked entities. Includes updated rules aligning with EIP-7702. These upgrades build upon v0.7 improvements, such as the removal of simulation functions, the addition of a delegateAndRevert() helper, ERC-165 supportsInterface support, and adjustments to gas penalty logic, further strengthening the ERC-4337 framework. Etherspot’s Skandha Bundler Supports EntryPoint v0.8.0 We’re thrilled to announce that Etherspot’s Skandha Bundler is among the first to fully support EntryPoint v0.8.0. Recognized on GitHub as the top-rated ERC-4337 Bundler, Skandha significantly optimizes user transactions. It offers decentralized and developer-friendly infrastructure specifically tailored for seamless integration with ERC-4337. With built-in MEV protection and robust support for the ERC-4337 Shared Mempool, Skandha enhances both transaction efficiency and security. Additionally, the bundler now supports EIP-7702 transactions, enabling it to seamlessly process 7702 authorizations as UserOperations. Currently, hosted bundlers supporting EntryPoint v0.8 are available and ready for use on Ethereum, Polygon, Arbitrum, Optimism, Base, Gnosis, Sepolia, Base Sepolia, and Amoy. By adopting EntryPoint v0.8.0, Skandha ensures our users benefit from greater compatibility, enhanced security, and optimized gas usage, ultimately providing a smoother experience across the Ethereum account abstraction ecosystem. You can explore the full list of ERC-4337 bundlers supporting EntryPoint v0.8.0 here. EntryPoint v0.8.0 marks another important milestone in making account abstraction more powerful, secure, and efficient. As early adopters of the latest standards, Skandha and Etherspot remain committed to bringing cutting-edge innovations to developers and end users, contributing to the continued growth and maturity of the Web3 ecosystem.

Etherspot’s Skandha Bundler Now Supports ERC-4337 EntryPoint v0.8.0

Account Abstraction (AA) has quickly become a game-changer for enhancing user experiences in Web3. The implementation of ERC-4337 brought essential new components into the ecosystem, such as Bundlers, Paymasters and the crucial EntryPoint contract.

Recently, the ERC-4337 team announced a significant update: EntryPoint v0.8.0. Let’s dive into what EntryPoint is and explore the latest improvements in version 0.8.

What exactly is the EntryPoint contract?

Think of EntryPoint as the heart of the ERC-4337 ecosystem. It’s the core contract responsible for processing UserOperations (UserOps), handling verification and execution logic seamlessly. EntryPoint acts as a singleton, meaning only one instance should exist on each blockchain, to ensure consistency and efficiency.

Key Features of the EntryPoint Contract:

Simplified Transactions: Execute transactions with smart contract-level logic, enhancing the user experience.
Boosted Security: Introduces robust verification layers and conditions, making interactions on the blockchain safer.
Developer Freedom: Enables developers to build advanced dApps by embedding complex transaction logic directly within user accounts.

What’s new in EntryPoint v0.8 compared to v0.7?

EntryPoint v0.8 brings crucial upgrades and essential fixes:

1. Native Support for EIP-7702 Authorizations:

Integrates delegation mechanisms directly into EntryPoint.
Includes delegation addresses in UserOperation hashes.
Verifies delegation addresses during processing.
Supports the eip7702Auth parameter in eth_sendUserOperation.
Adds an AUTH category within ERC-7562 validation rules.

2. ERC-712 Based UserOperation Hash and Signatures:
