The eth-infinitism account-abstraction repository holds the reference ERC-4337 contracts, including SimpleAccount, plus a TypeScript SDK from the authors of the specification. Builders use it as the baseline implementation when creating ERC-4337 accounts.

Alchemy aa-sdk, shipped as Account Kit, is a full-stack smart wallet SDK with embedded wallets and a gas manager. Application builders use it to give users an account and sponsored transactions without a separate wallet app.

Rundler 是 Alchemy 的模組化 Rust ERC-4337 捆綁器，旨在實現水平擴展部署；如今許多以太坊用戶操作工作負載都在其上執行。
