Lit Protocol

Cryptography & key management

SDK · 트랜잭션 서명 · 암호화

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.

noble cryptography는 읽기 쉬운 소스, 서명된 릴리스 및 투명한 npm 빌드를 우선시하는 최소 종속성 TypeScript 암호화 라이브러리 제품군으로, 메타마스크(MetaMask), Rabby, Rainbow를 포함한 대부분의 최신 JavaScript 지갑과 생태계 전반의 많은 SDK를 뒷받침합니다.

Trezor Connect

Trezor Connect is a JavaScript SDK for integrating Trezor hardware wallet signing, including Ethereum, into applications and wallets. Builders use it when users should sign with a Trezor device.

blst

blst is a multilingual BLS12-381 signature library and the BLS implementation behind most Ethereum consensus clients. Builders link against it in Rust, C, or Go when writing validator or consensus tooling.

@ledgerhq/hw-app-eth

The Ledger hw-app-eth package is the JavaScript API for signing Ethereum transactions and messages with a Ledger device, and it sits behind the Ledger connectors in wagmi and viem. Wallet and application builders import it to add hardware wallet signing.

py_ecc

py_ecc is a Python library for elliptic curve pairing operations over bn128 and BLS12-381, used by py-evm and other Python tooling. Builders import it for precompile or BLS work in Python.

eth-crypto

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.
