Unlimited Faucet

Virtual TestNets come with an unlimited faucet which you can use to fund or set an arbitrary amount of native and ERC-20 tokens to any account. Since there is no mining of tokens, funds will be instantly added to the account and available for you to use.

Accounts can be funded from the Dashboard or using custom JSON-RPC methods.

Dashboard unlimited faucet

From the Virtual TestNet dashboard, go to Faucet.

1. Paste an address or addresses (1 address per line)
2. Enter the desired amount in the nominal currency (not WEI)
3. Pick the currency. It can be one of:
   • Network’s native token
   • An existing ERC-20 token
   • Select use custom token address and paste the token’s address
4. Click Fund.

RPC unlimited faucet

You must use the Admin RPC URL to get access to the following RPC methods for manipulating account balances:

• tenderly_addBalance: Adds the balance to the provided account or accounts.
• tenderly_setBalance: Modifies the balance of an account or accounts.
• tenderly_setErc20Balance: Sets the token balance for the wallet on the provided erc20 contract. Does not emit a Transfer event.
• tenderly_addErc20Balance: Adds tokens to one or more wallets and emits a synthetic ERC-20 Transfer event for each funded account — use this when indexers or log-based tooling need to pick up the balance change.
• tenderly_setMaxErc20Balance: Sets the maximum token balance for the wallet on the provided erc20 contract. Does not emit a Transfer event.
