Use this simple Ethereum wallet desktop UI to create and sign offline Ethereum transactions that you can later provide to a public Ethereum gateway.
- Send Ether
- Transfer ERC20 tokens
- Call any function on any smart contract
-
Provide your private key as either raw, unencrypted bytes (you like living dangerously), or copy/paste your encrypted geth account file (safer).
-
You will need the ERC20 token's SCA (smart contract address) to transfer tokens.
-
You will need the SCA and the smart contract's ABI (abstract binary interface) to call a smart contract.
-
Be careful to ensure you are using the correct nonce.
-
The program gets the suggested gas price - check it through other sources and override if desired.
-
Includes minimized versions of jQuery, keythereum and web3 that may not be the latest.
-
Includes altered version of npm module secp256k1. See github issue.
