Module faucet

This module contains arguments and functions to fund some Ethereum wallets with native tokens and HOPR tokens

Despite HOPR contracts are mainly deployed on Gnosis chain, HOPR token contract addresses vary on the network.

Attention! Do not use this function to distribute large amount of tokens

Note that to save gas in batch funding, multicall is used to facilitate token distribution, via transferFrom To use this functionality, caller must grant Multicall3 contract the exact allowance equal to the sum of tokens to be transferred. As it’s a separate function, there is a window between granting the allowance and executing the transactin. Attacker may take advantage of this window and steal tokens from the caller’s account.

A sample command:

hopli faucet \
    --network anvil-localhost \
    --contracts-root "../ethereum/contracts" \
    --address 0x0aa7420c43b8c1a7b165d216948870c8ecfe1ee1,0xd057604a14982fe8d88c5fc25aac3267ea142a08 \
    --identity-directory "./test" --identity-prefix node_ \
    --password-path "./test/pwd" \
    --private-key ac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80 \
    --hopr-amount 10 --native-amount 0.1 \
    --provider-url "http://localhost:8545"
