Ontology Gas (ONG) is the utility token of the Ontology network, used to pay for transaction fees and smart contract execution on-chain. Users often swap ONG to fund on-chain activity within the Ontology ecosystem, or swap out of ONG after receiving it as part of staking rewards tied to holding ONT. Because ONG operates exclusively on the ONT network, the exchange process is straightforward with no cross-chain routing to manage.
Before swapping ONG, confirm that your receiving wallet or platform supports the ONT network, as ONG exists solely on that network — there is no alternative chain option to select. Double-check that the deposit address you provide is a valid Ontology network address, since sending to an incompatible address format can result in permanent loss of funds. On-chain confirmation times can vary depending on network activity, so allow some time for the transaction to be reflected in your wallet. No memo or destination tag is required for ONG transfers. The Zest exchange widget displays the estimated rate and the exact amount you will receive before you confirm, so review those details carefully before proceeding.
