On March 1, it is announced to launch its Mary Protocol which is the second of the two Hard Forks transforming $ADA from Shelley (a staking phase of the coin) to Goguen (a smart contracts phase of the coin).
With this, the native coins will be introduced creating multi-asset support in the Cardano network and because the tokens are on the same network and using the same ledger, it makes it easy for user-defined tokens to be used for contracts and behave exactly like ADA. The transaction between native tokens (based on Cardano ledger) does not incur an execution fee, allowing more room for affordability in terms of Applications developed on top of it.
