A Token Generation Event, or TGE, is the moment when a project’s native tokens are officially created and distributed for the first time. After a TGE, tokens typically become transferable and may be listed for trading. A TGE can include one or more mechanisms such as an airdrop, token sale, liquidity launch/listing, allocations with vesting/lockups, etc.
Points or contribution systems, like NUVA Points, can determine who gets how much at TGE, but that’s just one possible input, the essence of a TGE is bringing the token into existence and starting its lifecycle on-chain.
