ERC721 token that allows the users to mint using an authorization signed by the contract authorizer.

One weak transaction in ECDSA on the Bitcoin blockchain and with the help of Lattice Attack we received a Private Key to BTC coins

ECDSA Node Project for Alchemy University Ethereum Developer Bootcamp

A firebase project that authenticates clients with ECC / ECDSA (elliptic curve cryptography / elliptic curve digital signature algorithm) instead of password

ECDSA Node, Alchemy First Project

Client for a decentralized freelancing market

Ethereum bootcamp by Alchemy University, 1st week project

WIP -- notes: Incorporate Public Key Cryptography so transfers can only be completed with a valid signature. The person sending the transaction should have to verify that they own the private key corresponding to the address that is sending funds

A pure solidity implementation of elliptic curve math, parameterised for curve secp256r1 / prime256v1 / p256.

A deep dive into signing EVM transactions with an AWS KMS private key using JavaScript.

A full‑stack Ethereum “message signing & broadcasting” dApp built with Hardhat, Ethers.js, and React.

A small web app demonstrating ECDSA-based authorization. Users connect a wallet (MetaMask) and sign transfer messages (EIP-712). The Node server verifies signatures, checks nonces & balances, and updates accounts. Designed for local development and learning - private keys remain in the wallet and are never stored by the app.

ECDSA wallet + transaction ledger demo built with React and Node/Express. Generates Ethereum‑style addresses, signs transactions, verifies signatures server‑side, and tracks balances/nonces with a Merkle‑rooted transaction pool.
