BlockBeats news, on December 20, LayerZero initiated a proposal vote on 'Whether to activate the LayerZero protocol fee switch'. This proposal will determine whether LayerZero will start charging a protocol fee for each message, and the collected protocol fees will be used to repurchase and destroy ZRO, reducing its circulation.
Currently, messages between Arbitrum and Optimism incur a DVN/executor fee of $0.01. If the proposal passes, an additional protocol fee of $0.01 will be charged, bringing the total cost to $0.02. The $0.01 protocol fee will be collected in the funding contract, which will automatically repurchase and destroy ZRO.
