 ## Overview
 
 **MultiversX runs on a sharded architecture** - transaction, data and network sharding are leveraged. 
 
 In the Rosetta implementation, we've decided to provide a single-shard perspective to the API consumer. That is, **one Rosetta instance** would observe **a single _regular_ shard** of the network - the shard is selected by the owner of the instance.
 
-Currently, the Rosetta implementation only supports the native currency (EGLD), while custom currencies ([ESDTs](https://docs.multiversx.com/tokens/esdt-tokens)) will be supported in the near future. At that point, Rosetta would observe the _metachain_, as well.
+The implementation supports both the native currency (EGLD) and custom fungible currencies - [ESDTs](https://docs.multiversx.com/tokens/esdt-tokens).
