eth-keys

noble cryptographyは、読みやすいソース、署名されたリリース、および透過的なnpmビルドを優先する、依存関係が最小限のTypeScript暗号技術ライブラリのファミリーであり、メタマスク、Rabby、Rainbow、およびエコシステム全体の多くのSDKを含む、最新のJavaScriptウォレットのほとんどを支えています。

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 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.

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 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 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.
