Digital assets constitute an integral part of NEO Smart Economy, which consists of global assets (NEO & GAS) and contract assets (NEP-5). With the prosperity of NEO ecosystem, there is an increasing number of large dApps implemented on NEO, requiring diverse types of assets.

In response to the community voices, NGD developed CGAS, a contract asset that maps GAS to the contract. CGAS is a NEP-5 token with a total supply of 100 million, equal to the total supply of GAS. According to Chris Chen, NGD senior blockchain developer, “As NEO game ecosystem is becoming more complete, there is a growing requirement for GAS application scenarios. Take in-game assets for example, assume it costs 5 GAS for in-game purchase of a gear, since direct invocation of global assets is not technically supported, we thus develop CGAS, convertible to GAS at a 1:1 ratio. This way, GAS can be transferred within contracts and you can simply pay with CGAS. Special credit to NEL, a Chinese NEO developer community, who has contributed to the design and coding of CGAS.
