Orbiter chain zkSync bridge users can now use USDC and USDT as gas fees instead of ETH!
If you use the bridge, you should also use the Paymaster feature. High % will be one of the conditions for receiving the zkSync Airdrop.
$HOLD will be integrated for payment on Orbiter soon... (It is possible that when integrated, using $HOLD will be supported for a 50% fee reduction like on Syncswap)
