Ontology Gas (ONG): What It Is, Uses and Risks

ONG, short for Ontology Gas, is the utility token of the Ontology network, a public blockchain project that describes its aim as distributed trust and digital identity. Ontology uses two tokens. ONT is the main coin and is used for staking in consensus, while ONG is used for on-chain services. According to the project, ONT releases ONG periodically, so ONG reaches the market through a gradual release rather than a single sale. Ontology's MainNet went live on June 30, 2018, which is the launch date listed for the token. Public listings group ONG under Layer 1 tokens because it is tied to Ontology's own chain. The name reflects its role: like gas on other networks, it pays for activity on the chain.

Public descriptions say ONG pays transaction fees on the Ontology network and covers the cost of running smart contracts. Some sources also say ONG is distributed to people who stake ONT, and that it helps reward the validators who keep the network running. Ontology's framework includes modules for areas such as digital identity and data exchange, and those services would need an on-chain fee token to operate. Public sources supplied for this page do not give a full list of ONG-based services or explain how reward rates are set. Readers should check the project's current documentation before relying on any detail. Holding ONG does not guarantee a return, and no yield should be assumed.

As of 2026-11-05, the data shows about 485 million ONG in circulation, a total supply of 800 million, and a maximum supply of 1 billion. The gap between circulating and total supply means more tokens may enter circulation over time as the release schedule continues. At the time of writing, the price was about $0.0689, the market cap about $33.4 million, and the fully diluted valuation about $55.1 million, ranking 613th by market cap. Over seven days the price fell about 5.1 percent, and over one year about 27.4 percent. The all-time high was about $4.39 on 2018-09-28, and the all-time low about $0.0402 on 2026-08-12. These figures change constantly and do not indicate future prices.

Public sources supplied list Ontology as the chain where ONG is issued. They do not list any other chain where ONG is the native token, so this page does not describe ONG on other networks. Because ONG depends on Ontology's activity, its usefulness and demand are tied to how much the network is used. Readers who see ONG listed elsewhere should confirm which network a specific token address belongs to before they send or receive funds. Mixing up networks is a common cause of lost funds.

ONG carries several risks. Its price has moved sharply, and it has fallen a long way from its 2018 peak. Trading volume is modest compared with the largest tokens, so large orders can move the price. The release of new ONG over time can add supply and affect price. ONG's value depends on one smaller network, so problems with Ontology's development, security or adoption would affect it directly. Scammers often impersonate projects, so use only official sources for addresses. For storage, use a wallet that supports the Ontology network, confirm the network before receiving tokens, keep your seed phrase offline and never share it, and send a small test amount before moving larger sums.
