A mainnet swap occurs when a cryptocurrency project switches from a third-party blockchain network, like Ethereum, to its own blockchain network.
When a cryptocurrency project is at the testnet stage, a third-party blockchain network is utilized. However, users receive native cryptocurrency in place of their third-party tokens whenever the project transitions from the testnet phase to the mainnet phase. It also goes by the names token migration and token swap for this reason. The mainnet swap’s primary function is to exchange third-party tokens for the platform’s native coin.
