Try Quests to earn cryptoOptimism Scavenger Hunt
at this hunt insted of paying so much fee on eth mainnet and optimism mainnet on metamask wallet we tried a different way that allowed by Branden on discord channel. we swaped MATIC to SNX on UNISWAP DEX then bridge it from polygon network on optimism in transferto.xyz then for staking fee we also boght WETH on uniswap from matic then bridge it to optimism on hopexchange. after all now we have ETH to pay fee and SNX to stack so we stacked SNX on https://staking.synthetix.io/ .
