# Native Token API

Ontology uses a dual token (ONT and ONG) model. ONT is a coin and can be used for staking in consensus, whereas ONG is a utility token used for on-chain services.

The decimals of both tokens has experienced a change. Now ONT has 9 decimals, and ONG has 18 decimals. API methods with a suffix of "V2" in their names are designed to accommodate this change.
