Looks good to me, but was this tested in any way?

If there is any way to test through testnet or a local network would be nice to make sure this doesnt crash

Perhaps some unit test
Where you mock the tap Subgraph response for the escrow balance
To get the expected outcomes
One where it wont pass due to it not being enough and another test where it continues the desired path

Hey @carlosvdr and @dwerner could you do another review here?

Oh yes this is nice! Works for me , great job :)
