About
WalletDeploy (powered by ColdAuth) is a browser-based tool for deploying, upgrading, and managing Solana and EVM smart contracts without requiring CLI access or exposing private keys. It works with popular software wallets like Phantom and MetaMask as well as hardware wallets via WalletConnect, submitting top-level signed transactions directly to the blockchain. It also offers a CLI and VS Code extension for developer workflows, all with an on-chain audit trail.
Problem
Existing tools like CLIs require exposing private keys or hot keypairs, and multisig middleware cannot sign top-level admin transactions required by blockchain runtimes.
For
Blockchain developers and protocol teams managing Solana or EVM smart contracts
How it works
ColdAuth runs entirely client-side in the browser, constructs transactions deterministically from user inputs, and sends them to the user's connected wallet (software or hardware) for direct signing and broadcast to the blockchain.
