## Why do I get "transaction failed" error? 

If you are using Nami, it is very likely that you have not set a collateral amount; for more info, see [this article](https://docs.cardano.org/plutus/collateral-mechanism).

You can also follow these steps to fix the issue.

* Click on your wallet icon, then select "Collateral".

## How can I get tADA, and tINDY?

For tADA, you may go the [Cardano testnet faucet](https://docs.cardano.org/cardano-testnet/tools/faucet), select the Preview Network and provide your wallet address (make sure it is a Preview Network address); to receive 10,000 tADA per day.

For tINDY, you may go to the [Sundaeswap DEX](https://testnet.sundaeswap.finance/), and swap your tADA for tINDY (Policy ID: fa3eff2047fdf9293c5feef4dc85ce58097ea1c6da4845a351535183).
