* If the sender's inputs' sequence numbers are all the same, check that the receiver's contributed inputs match those.
* If <code>minfeerate</code> was specified, check that the estimated fee rate of the payjoin proposal is not less than this value.
* Check that outputs from the original PSBT has not been modified except if:
* The output can contribute to fee (see below)
* The output does not belong to the sender.
** The output can contribute to fee (see below)
** The output does not belong to the sender.
If a fee output exists, (ie, <code>maxadditionalfeecontribution=</code> and <code>additionalfeeoutputindex=</code> have been set by the sender), the sender must checks:
* The amount that was substracted from the output's value is less or equal to <code>maxadditionalfeecontribution</code>. Let's call this amount <code>actual contribution</code>.
* The <code>actual contribution</code> is less or equals to the difference of absolute fee between the payjoin proposal and the original PSBT. (This make sure the contribution actually goes to fee)
* The <code>actual contribution</code> is less or equals to <code>originalPSBTFeeRate * vsize(sender_input_type) * (count(original_psbt_inputs) - count(payjoin_proposal_inputs))</code>. (This make sure the contribution only pays for additional inputs, see [[#fee-output|Fee output]] section)
If a [[#fee-output|fee ouptut]] exists, the sender must checks:
* The amount that was substracted from the output's value is less or equal to <code>maxadditionalfeecontribution</code>. Let's call this amount <code>actual contribution</code>.
* Make sure the contribution are only paying fee: The <code>actual contribution</code> is less or equals to the difference of absolute fee between the payjoin proposal and the original PSBT.
* Make sure the contribution are only paying for fee incurred by additional inputs: <code>actual contribution</code> is less or equals to <code>originalPSBTFeeRate * vsize(sender_input_type) * (count(original_psbt_inputs) - count(payjoin_proposal_inputs))</code>. (see [[#fee-output|Fee output]] section)
The sender must be careful to only sign the inputs that were present in the original PSBT and nothing else.
