 To make Testnet WAL available to all who want to experiment with the Walrus Testnet we provide a
 utility and smart contract to convert Testnet SUI (which also has no value) into Testnet WAL using
 a one-to-one exchange rate. This is chosen arbitrarily, and generally one should not read too much
 into the actual WAL denominated costs of storage on Testnet. They have been chosen arbitrarily.
