Everyone knows the admin key should be on a cold wallet.
But no tool lets you actually use a cold wallet for contract admin.
Without ColdAuth
❌ Remix — no hardware wallet
❌ Hardhat — needs key file
❌ Etherscan — no WalletConnect
❌ Safe — can't deploy or upgrade
Cold wallet = paperweight
With ColdAuth
✅ Deploy tokens
✅ Pause / unpause
✅ Transfer ownership
✅ Upgrade proxies
All from your Tangem or Ledger
Your cold wallet can finally deploy and manage contracts.
Connect via WalletConnect. Sign on your hardware wallet. Done.
No CLI. No .env files. No private keys on any computer. Ever.
EVM Contract Management
Connect your hardware wallet to deploy and manage smart contracts on any EVM chain.
