This module provides native bindings to ecdsa secp256k1 functions
wrapper around plume_rustcrypto crate to produce PLUME signatures in JS contexts using Wasm
Blockchain Commons Cryptographic Utilities for TypeScript
TypeScript SDK for ottochain metagraph operations - signing, encoding, and network interactions
TypeScript SDK for signing data transactions on Constellation data metagraphs built with metakit
Core kernel for the Constellation metagraph SDK: hashing, canonical serialization, and signing primitives. Generic and offline.
Open-source verifier for BIPCircle stablecoin reserve attestations. Re-derives PASS/FAIL from primary sources (XRPL, bank-service JWKS, on-chain token supply) without trusting BIPCircle or Lazy-Jack infrastructure.
TypeScript port of VTEX.DataSigner — sign protobuf and JWT ES256 payloads against the VTEX data-signing key store; cryptographically compatible with the original .NET VTEX.DataVerifier.
Apache-2.0 verifier for Android Hardware-Backed Keystore Attestation hardware-attestation credentials — offline X.509 chain verification against pinned Google Hardware Attestation roots (RSA-4096 + ECDSA P-384), plus ASN.1 extraction of the KeyDescription
MCP server for Coinbase Developer Platform (CDP) — single package covering Trading, Wallets, and Payments. Auth uses ES256 JWT signed with an ECDSA P-256 private key minted at portal.cdp.coinbase.com.
Keep ECDSA Wallet
The PKPSuiWallet class is a specialized wallet for the SUI blockchain using signing scheme based on ECDSA Secp256k1. It's modified version of SignerWithProvider class from the @mysten/sui.js library. This class wraps the 'PKPBase' class and implemen
The aw-tool-sign-ecdsa package provides functionality for performing ECDSA signing operations using Lit Protocol's PKPs (Programmable Key Pairs). This tool enables secure signing of arbitrary messages or transactions while enforcing policy-based control
The crypto.ts file in the Lit SDK handles cryptographic operations, including the generation, import, encryption and decryption of keys, as well as management of cryptographic shares using BLS and ECDSA schemes.
