+Abstract
+========
+
+A standard interface for defining a smart contract wallet that can hold and transfer native currency and cis2 tokens. 
+Native currency/Cis2 tokens can be deposited into the smart contract wallet by
+specifying to which public key the deposit should be assigned. 
+
+The holder of the corresponding private key is the only entity that can authorize 
+to transfer tokens/currency in a self-custodial manner 
+from the public key balance (assigned in the smart contract) to some new accounts/smart contracts/public keys.
+
+The holder of the corresponding private key does not have to submit transactions 
+on chain to transfer its native currency/cis2 token balance,
+but instead, it can generate a valid signature, identify a willing third
+party to submit its signature on-chain (a service fee can be added to financially incentivize a third party to do so).
+
+The three main actions in the smart contract that can be taken:
+
+- *deposit*: assigns the balance to a public key within the smart contract wallet.
+
+- *internal transfer*: assigns the balance to a new public key within the smart contract wallet.
+
+- *withdraw*: withdraws the balance out of the smart contract wallet to a native account or smart contract.
+
+The goal is to simplify the account creation onboarding flow on Concordium 
+allowing for CIS5 smart contract wallets to be supported as first-classs citizens on Concordium wallets and tooling.
