To fund an AEA for testing on a test-net you need to request some test tokens from a faucet.
Add a private key to the agent:
aea generate-key fetchai aea add-key fetchai fet_private_key.txt
aea generate-key ethereum aea add-key ethereum eth_private_key.txt
Using a faucet website
First, print the address:
aea get-address fetchai
aea get-address ethereum
This will print the address to the console. Copy the address into the clipboard and request test tokens from the faucet here for Fetch.ai or here for Ethereum. It will take a while for the tokens to become available.
Second, after some time, check the wealth associated with the address:
aea get-wealth fetchai
aea get-wealth ethereum
Using the cli
Simply generate wealth via the cli:
aea generate-wealth fetchai
aea generate-wealth ethereum
