Candide builds open Account Abstraction Infrastructure & Software, focusing on Ethereum Migration from EOAs to Smart Accounts.

About the project

Candide is a team that contributes to ERC-4337 standard through open source software. These includes: a python-rust Bundler Node, a Safe Smart Account SDK, a Paymaster and a mobile smart wallet.

Voltaire 4337 Bundler

A modular, developer-friendly and lighting-fast Python-Rust Bundler for Ethereum ERC-4337 Account Abstraction. Voltaire is designed to operate within the peer-to-peer mempool of UserOperations, facilitating the inclusion of transactions on-chain more quickly and efficiently.

Voltaire presently has complete coverage of the compatibility test suites written by ERC-4337 team. These test suites ensure that different bundlers can communicate effectively and defend against DDoS attack vectors.

Voltaire is open-source, meaning that anyone can launch Voltaire and start bundling user operations for a service fee. By enabling anyone to participate in the network, the mempool becomes more robust when facing censorship attacks.

We give acknowledgement to both Trinity and Lighthouse, open-source Ethereum clients implementation written in Python and Rust respectively.

AbstractionKit SDK

A Typescript library to build and send UserOperations (the type of transactions sent by Smart Accounts). AbstractionKit features:

• Battle tested Safe Contracts as the Base for Smart Accounts
• Passkeys Plugin for Account Security
• Social Recovery with Guardians Plugin
• Gas Fee Abstraction with Paymasters
• One-click experiences with Batched Transactions
• Multisig support

Candide Wallet

A mobile smart wallet - Available on both IOS and Android. Featuring:

• On-Chain Recovery - Forget Seedphrases. Recovering a wallet though designated Recovery Contacts
• Decentralized Focused - Designed to be censorship resistant and free from third party control with ERC-4337
• Dapp with a Single Tap - Leveraging the power of Account Abstraction, bringing bundled calls in standardized way
• Pay Network Fees with Stablecoins - Pay gas fees with supported ERC-20s

For a bit of background, EIP 4337 is the account abstraction standard for Ethereum & EVM equivalent chains that doesn't compromise on decentralisation and censorship resistance. In practical terms, this means smart contract wallets that don't depend on centralised relayers controlled by a single entity. The role of centralised relayers is replaced with a p2p network of new entities called Bundlers. As the p2p network is still in development, bundlers currently operate as standalone endpoints until they are able to participate in the unified mempool.

The problem it solves

Our goal is to transition ethereum externally owned accounts (EOAs) to Smart Accounts.

Funding plans

• Support Voltaire ERC-4337 and AbstractionKit with new Entrypoint v0.7
• Add new features to AbstractionKit to developers to build on Smart Accounts
• Prepare support for RIP-7560 Native Account Abstraction
