How to pay no fees?

0

Is there any API where I can create some addresses and making a transaction beetween them just once a month without paying fees?
Or if you can recommend me somewhere with a fee under 5000 satoshis it would be great.

Thanks in advance.

So you want to automate / schedule a periodic transaction? – Geremia – 2015-06-13T05:06:17.257

Yes, but with a fixed percentage, not a fixed amount. – Rafael – 2015-06-14T14:34:53.663

It is possible. However, such a NO FEE transaction with small amount of Bitcoin involved could delay your transaction. Your transaction might stay unconfirmed for a long time.

Here is basic idea to make a no-fee transaction:

  • Split your one of your unspent_transaction_output into two part. UTXO_1 and UTXO_2
  • Send UTXO_1 to receiver's address; send UTXO_2 to your own address
  • Make sure that UTXO_1 + UTXO_2 == your unspent_transaction_output

    • Follow this link to make a no-fee transaction. https://bitcoin.org/en/developer-examples#simple-spending

    The Blockcypher Microtransaction API is free, they eat the transaction fee's for you if you're looking to send small and free transactions.

    You could setup a cronjob to run createrawtransaction, sendrawtransaction, etc. commands monthly. Cf. "Creating, Signing, and Submitting Transactions Based on Unspent Outputs" of Mastering Bitcoin.
