2-of-3 multisignature account with limitations on withdrawal I want to create a 2 of 3 multi-signature account from where one can withdraw money only after a certain period of time. How can this be done?
You will likely need to add an OP_CHECKSEQUENCEVERIFY guard before the OP_CHECKMULTISIG statement in your output script.
