eth-crypto is a set of JavaScript helpers for signing, verifying, recovering addresses, and ECIES encryption alongside ethers or web3. Builders import it for one-off cryptographic steps that the client libraries do not expose directly.

noble cryptography

noble cryptography 是一系列依賴性極低的 TypeScript 密碼學函式庫，優先考慮可讀的原始碼、已簽署的發布版本和透明的 npm 建置，它們是大多數現代 JavaScript 錢包（包括梅塔馬斯克 (MetaMask)、Rabby、Rainbow）以及整個生態系統中許多 SDK 的基礎。

Web3Signer

Web3Signer is a remote signing service that keeps keys in a vault or hardware security module. Node and validator operators run it so signing happens outside the client process.

Fireblocks SDK

The Fireblocks SDK connects applications to Fireblocks' MPC wallet infrastructure for signing, transfers, and treasury operations. Builders use it to automate transactions and approval policies for wallets managed through Fireblocks.

Turnkey

Turnkey offers an API and SDK for secure key generation and transaction signing backed by trusted execution environments. Builders use it to create and operate wallet infrastructure without holding raw private keys in their own code.

Lit Protocol

Lit Protocol is a decentralized network for threshold key management with programmable signing through its programmable key pairs. Builders use its SDK when signing or decryption should follow rules enforced by a network rather than a single key holder.

eth-keys

eth-keys is a Python library for secp256k1 keys and signatures, and it sits under eth-account and web3.py. Python builders import it when they need key and signature operations directly.
