### A note on native(BTC) transfers

Due to the way utxos work, there is no concept of point to point A->B native transfers in bitcoin. in each tx, a bunch of utxos are spent, and another bunch created, and we cannot reliably conclude that address X sent some amount to some address A.

A more concrete example:

</Frame>

**Question**: How much did X and Y transfer to A,B,C,D?

**Answer**: Depending on how we ‘view’ the sats in the input utxos, there can be many different answers to the above question.

**Possibility 1 **- if we say input sats in a utxo move to the output side in a first-in-first-out (FIFO) manner:

</Frame>

**Possibility 2 - **multiplexed from inputs to output. each input is proportionately split into all the outputs

</Frame>

**Possibility 3** - any other logic mapping inputs to outputs (e.g. maybe we assume input0 always pays for the gas?)

Depending on the use case of the analysis, how input/outputs translates to transfers will be drastically different. Feel free to reach out to the team to clarify/for assistance in implementing a preferred style!
