I’m trying to transfer funds out of Coinbase and into my Blockchain wallet but when I enter the wallet id and address, I keep getting an “invalid address message”.
Does your Blockchain wallet address start with a 1 or a 3? If it’s a 3, then it’s a multisig address. Coinbase should support those but it’s possible they don’t. Neither Coinbase nor Blockchain support SegWit addresses at this time, which rules out SegWit addresses as an issue.
If you enter the address into Blockchain’s block explorer, does it return as valid? If valid, it will show previous transactions If any, otherwise it’ll say the address hasn’t been seen on the blockchain yet. If the address is invalid, Blockhain will return an error, in which case the most likely explanation is that you copied it wrongly.
