Could someone take me through making a no fee transaction (again)

[jackg]

Someone told me how to do it last time (and I still couldn't hack it so gave up), I'm at my hacking again (of my raw tx) and have made this:

Code:

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

And now I'm stuck.
They said look for the hexadecimal conversion of the amount I want to send in satoshi which is 99699₁₀ 18573₁₆

I saved that in a file called tx (the raw tx, original aren't I )?

I then ran cat tx | grep "18573" and then cat tx | grep "37581" and couldn't find them.
I'm trying to test out multisig here so I'm hoping to send a no fee transaction for that and then go on to consolidate a few inputs (I can't push it though as I can't host a node so I'll have to be a bit more creative this time ).

you have to find the "amount" field in your transaction by deserializing it first then replace that with new amount you want to pay then serialize the transaction again. it seems like you just appended "45505446ff00" at the beginning of the transaction for some reason!

this is your current amount: 7385010000000000₁₆ = 99699₁₀
this is what you want to set it to: 100000₁₀= A086010000000000₁₆

you can get A086010000000000 from your previous output too! just deserialize b0b610f02d097a5a88215ccfd3368feda907ac5baf330f163720a19685dd9c4a and find a9144d5864b9c56086e0ebda1806c6c775a5ebdef0c987 in it and your get your amount field there.
