What is Smart Contract collateral?

To make Smart Contract transactions on Cardano it is necessary to set collateral in the wallet. Collateral exists in case there is a validation failure of a Smart Contract transaction on the chain; a small amount of the collateral will be taken to cover execution costs. 

However, we do not expect smart contract transaction failures to happen so if any do happen please submit a ticket to support with the transaction ID of the failed Smart Contract transaction (must be from our platform) and we will happily assist you.
