Safe{Core} SDK

Safe{Core} SDK - Smart Account Infrastructure for Developers

Product Overview

Safe{Core} SDK is the most trusted smart account infrastructure for building wallet functionality into applications. Powering 57+ million deployed wallets and securing over $60 billion in assets, Safe{Core} enables developers to integrate multisig security, account abstraction, and programmable wallet features without building from scratch.

Core Product Features

Smart Account Infrastructure

Modular Smart Accounts: Deploy ERC-4337 compatible smart accounts with customizable security policies. Safe's modular architecture allows developers to add, remove, or upgrade account features through a plugin system of modules and guards.

Multi-Signature Security: Built-in N-of-M threshold signing eliminates single points of failure. Configure any combination of signers with flexible approval thresholds for enterprise-grade security.

Account Abstraction (ERC-4337)

Gasless Transactions: Enable sponsored transactions through paymaster integration, allowing users to transact without holding native tokens.

Batched Operations: Bundle multiple transactions into single operations, reducing gas costs and improving user experience.

Social Recovery: Implement guardian-based account recovery mechanisms, eliminating the risk of permanent fund loss from lost keys.

Developer Tools

Comprehensive SDKs: TypeScript/JavaScript libraries for seamless integration with frontend applications. Full API access for backend services and automation.

Protocol Kit: Deploy and manage Safe accounts programmatically across 25+ supported networks.

API Kit: Access transaction service APIs for proposal creation, signature collection, and execution.

Auth Kit: Implement authentication flows with support for passkeys, social logins, and hardware wallets.

Multichain Deployment

25+ Networks Supported: Deploy identical smart account infrastructure across Ethereum, Polygon, Arbitrum, Optimism, Base, Gnosis Chain, Avalanche, BNB Chain, and more.

Unified Address: Same account address across all supported networks for simplified cross-chain asset management.

Key Product Differentiators

Battle-Tested Security: 18+ security audits and formal verification. The most audited smart contract wallet infrastructure in the industry.

Open Source: Fully transparent, independently verifiable codebase with no vendor lock-in. Accounts remain accessible even if Safe services are unavailable.

No AUM Fees: Unlike MPC custody solutions, Safe charges no percentage of assets under management.

Ethereum Ecosystem Standard: Used by Ethereum Foundation, adopted by major protocols, and endorsed by Vitalik Buterin as his personal wallet solution.
