Definitions of OneBalance-specific terms and relevant Web3 concepts
Account/Gas Abstraction - A blockchain technology that allows smart contracts to act as user accounts, enabling features like gas sponsorship, batch transactions, and custom authentication methods. See also: EIP-4337, EIP-7702. Learn more about OneBalance’s implementation in Account Models.
SCA (Smart Contract Account) - An alternative to EOA, a blockchain account controlled by smart contract logic rather than a private key, enabling advanced features like multi-signature, spending limits, and account recovery. See Account Models for supported configurations.
Credible Accounts - A new account model that extends external accounts, smart contracts, and stateful accounts with the ability to issue Resource Locks. Details in Account Models.
Kernel - The smart contract account implementation used by OneBalance, based on ZeroDev’s open-source framework. Two versions are currently supported:
ECDSAValidator - A validator module that uses the standard Elliptic Curve Digital Signature Algorithm for authentication, compatible with most existing wallet infrastructures.
RoleBasedValidator - A validator module that enables sophisticated access control with different permission levels for various operations, currently supporting Fast Path execution only.
EIP-4337 - The Ethereum Improvement Proposal that defines the Account Abstraction standard, enabling smart contract accounts across EVM chains without consensus-layer changes.
EIP-7702 - A newer Ethereum Improvement Proposal that provides an optimized approach for account abstraction with potential gas savings through delegated smart contract authentication.
Bundler - A service that aggregates multiple user operations into a single transaction for submission to the blockchain, optimizing gas costs and execution efficiency.
Paymaster - A service that sponsors on-chain gas fees on behalf of users, enabling gasless transactions and improving user experience.
WaaS (Wallet-as-a-Service) - Cloud-based wallet infrastructure that enables applications to offer embedded wallets without requiring users to manage private keys directly. Examples include Privy and Turnkey.
Frontier Research - An independent research and advisory group that publishes research, incubates products, and organizes community events, including the Cake Working Group.
Fellowship of the OneBalance - An industry group united under the common mission to implement the Credible Stack and bring Credible Accounts to Web3.
