ZigZag on Arbitrum is an expansion to showcase how ZigZag's EVM contracts work while awaiting the release of zkSync Era. When zkSync Era launches, ZigZag will be using similar contracts. Once these contracts are fully finished, ZigZag can be expanded to any EVM chain.
Arbitrum has allowed us to add more benefits and features, such as partial fills, infinite limit orders and protocol fees.
Takers pay gas fees to the fee address and protocol fees are collected in the same fee address: https://arbiscan.io/address/0xf4bba1e2a5024a2754225b981e9a0db7d2c33ee9.
