alright so we just heard that delighted
to toxic artists are know so I'm at the
market I'll start the first one where
I'm going to present you to UVM hunter
to see you can only dance now what is it
actually about it's a tool by which I'm
going to introduce to you the first we
have the Lord on some dad's here are
some deaths from the Dead River and then
you can see some things that the Raiders
show that they're apparently 1,028 to
the absolute history that might be more
flying flowing around the chain but this
is a number which is what just sit there
and so we all know that executing the
smart contract costs gannets whatever we
like yeah the main question is which I
also so myself have they mean optimize
it or are they waste in your gas when
you interact with them okay so that's
the EDM actually steal your gas because
the smart contract has been not
optimized do you know what kind of code
you're using there if you hate making
more gas than you should have
so we will actually a tool it looks like
this here you have to be I'm not sure
what you do is all you have to do is
just type in the address of smart
contract and it tells you gossip CQ ssin
how much gossip waste actually
the execution time and also how much gas
and waste turned into wine in time so
well what do you have to do is type in
smart contractors will you meet me Tomas
- it's okay we distribute it and you can
see it can be Robson can be main that
can be any network and you can just see
how much of gas this smart contract is
wasting so the idea is also to put
pressure on the developers that they
start to think hey I have to optimize
smell my smart contracts because two
people are able to see if I did a good
work at all so yeah then for example
what happens is possible to distinguish
between an account or a smart contract
so if you type in and wallet address
with good oxygen someone just doesn't
store any code Yahoo - tell me so on the
other hand what is this - Lulu it
retrieves the byte code from the chain
analyzes it based on some hunt and any
patterns which happened to the stripe in
the paper and just gives you the result
at the end so you might ask where do I
find this tool you can find it either on
their EP I'm not sure go buy both of the
just a QR code if you want to test it
out
it is also github so under my evolve so
feel free to extend this tool if you
know any more
patterns you know what you know we want
to make school you maybe you better it's
something that's feel free to contribute
and make use of it
thank you
