Is there a way to look up any address online by typing the first few characters?
Say I want to find 1ESvmL4k3wHsthoADGD5EQXmyaCCHnYQei; it would be great to type in only 1ESvmL and then get the entire address.
Obviously such a service would only work for addresses that have at least one transaction.
Not sure if I understand you correctly but if you copy and paste it in your browser in something like blockchain.info your browser will remember it so you only have to type the first few characters every time for it to come up. You might want something different though.
