Don’t confirm if the gas fee is above 1 ETH, probably contract error. (5) Ethereum confirms -> SPANK back to your walletMigration to Optimismhttps://gateway.optimism.io/ go here and connect metamask and choose spank to send to optimism. You need 2 tx one to approve and second to send a certain amount to optimism.Transactions basically deposit spank to this contract and creates tokens on optimism. you can see all the spank sent to the contract here https://etherscan.io/token/0x42d6622dece394b54999fbd73d108123806f6a18?a=0x99c9fc46f92e8a1c0dec1b1747d010903e884be1Once you do this you will have your tokens on optimism. luckily etherscan has optimism data. As you can see both contracts have the same amount of spank. this one shows the Spank token on optimism network. https://optimistic.etherscan.io/token/0xcfd1d50ce23c46d3cf6407487b2f8934e96dc8f9Optional - Using uniswap on optimismOpen your metamask and go to https://app.uniswap.org/#/swap?chain=optimism It will automatically add optimism network to metamask. Alternatively you can use https://chainlist.org/now you need optimistic ETH, which is OETH. One way to get it is to use optimism gateway but it costs a lot so another options is to use hop. If you are on matic, arbitrum, or xdai you can send ETH to optimism with very low tx cost, also if you time it right you can get more eth on the other side.https://app.hop.exchange/#/send?token=ETH choose the network and amount and send it from here and you will have it on optimism in 5 minutes. Now you have your spank and some ETH there.To trade spank on optimism you have to manually add Spank token contract address which is 0xcfd1d50ce23c46d3cf6407487b2f8934e96dc8f9. Or you can click https://app.uniswap.org/#/swap?chain=optimism&outputCurrency=0xcfd1d50ce23c46d3cf6407487b2f8934e96dc8f9&inputCurrency=ETHIf you have questions you can reach out to me on Spank discord.
