I have over 1400 small transactions in my wallet that add up to a little over 0.2 BTC. I am trying to send them, but keep getting a transaction too large error. I have tried to set a custom transaction fee, but am unable to still send. I am using Bitcoin core v0.10 on Windows. I have looked at this thread but am still unable to find a solution.

How can I combine all the tiny amounts I've received to minimise transaction fees, and do I need to?

    Does it say 'Transaction too large' or 'Transaction too large for fee policy?' They're different errors.

  • It says just says "Transaction too large"

Your scriptSig is too big! It is limited to 200 kbytes, and you've got 1400 inputs @ 0.2kbyte (best case scenario): 1400x 200 = 280kbyte.

Try using half the inputs (preferably newer inputs) to cut the scriptSig down in size.

    Why newer inputs? Wouldn't older inputs have a higher priority?

  • @NickODell Yep, just "picking the better half" so to speak Apr 30 '15 at 5:17

    @WizardOfOzzie The older ones are the better ones. Apr 30 '15 at 6:01

    @PieterWuille I personally would try sweeping up the worse (newer) ones to hopefully comprise a fee-free Tx. I'm not disputing the priority being inversely proportional to age; it's more a difference in opinion of how to handle dust, but tbh, I'll defer to you here! Apr 30 '15 at 6:46

    Priority is proportional to age, not inversely. And every output spent has its own scriptSig in the txin, which is around 105 bytes total per output spent. Apr 30 '15 at 10:19
