How to get started sending a Mailchain test message on a testnet
To send testnet messages using Mailchain, you will need an Ethereum address with a small balance (around 0.0007 Ether).
Ethereum addresses are valid across the Ethereum mainnet and testnets, so it's best to create a new address for development purposes only. This way, if your private key gets exposed, only test ETH can get stolen.
1. Create an Ethereum Address for Testing/ Development
Because you have not yet sent any transactions from this ethereum address on this network, Mailchain won't be able to be able to determine your public key.
If this is the first message or transaction you are sending on this testnet:
Click "COMPOSE" in the Inbox interface and send a message to an ethereum address which has already sent a transaction, e.g. the Mailchain Developer address: 0x4ad2b251246aafc2f3bdf3b690de3bf906622c51.
If you have sent a message or transaction on this testnet, you can receive messages from other developers, send messages to yourself, either from the same address or another development address.
Top tip: Because Mailchain supports ENS, you can configure an easy, human readable name for your development address on the testnet you are working on. This makes it easier to keep track when switching between different addresses.
