my name is Connie I have a party over
offensively you may know because of the
security lights we perform we added the
silicone primarily I did the Ciroc
retreats for home base we either broke
serpent by these days most recently we
are using compound and in style you also
may know us because of the open selling
contracts aka open sibling solidity
report which you may know about and one
of the most uses libraries in the system
with more than 2k down those but today
I'm not going to give us security I'm
not talking about the contracts repo I'm
going to give up to tools we got being
developing with our team which are the
opens Elena as decay and the organs of
the strata kids so first of all why well
we really think that development tools
right now in the system are still green
compared to other you know ecosystems to
other industries and we love to build
things for you guys that's why we
basically build these two tools and
we're gonna start with the open seven
cking do opens up instigate a success or
development keys or
- which has a CLI that will let you
develop your contracts compile them
using any Soviet version you want deploy
Emily's upgrade them interact with them
again using the CLI and startups in only
five minutes but now right well this is
an empire so just run in npm install at
open 7 / CLI we will do the trick
well so how you can start your project
super easy after installing it just when
open sampling it will start everything
you need to start coding your contracts
you then probably will want to go your
contract which for example could be a my
contract with a function that is called
to something that will subside something
parameter i'm just 40 point you just
have to run opens that we create
specifying the contract name which never
you want to deploy to we're just not
really necessary because all these
comments are interactive and if you
don't specify the parameters nor the
flags you won't have any problem and you
know will deploy only with duck command
the
and now that we have our contract
deployed we probably want to tell with
it which is against Parisi the open cell
in CLA has two super handy demands which
are called inference actually call
basically for calling purely functions
and center section for calling any other
public function and will actually made a
transaction to the blockchain under
super super easy to use and as we don't
know development software yeah
software development and again the cycle
of software development has its problems
we are humans developers about human sin
we commit mistakes we know that by just
seeing the history of contraband and all
the money that was lost in security so
maybe you want to update a break our
broken content which is again super easy
with this tool you just have to you know
modify your broken function a new
awesome cool and just run open simply
upgrade specify your project and the
salt
DCL I will upgrade your contract and as
you can see it is deployed in exactly
the same address as people screen the
first time I'm not gonna go over it even
this topic but if you want to ignore on
how we are implementing this please go
to the airplane slash upgrades but
anything else that's DCL is anything
else yet apart from the commands in the
Left we have our super handy commands
compact for compiling your contracts
with any version of so later you won't
verify for verifying to either side or
either speaker chain
opens up here
a specific network transfer for
transferring ether or your FC Twente
tokens to any account balance to query
the balance on any on situations for
ease of hanging hands and I wanted this
last permanently unpopular because this
is the link we have with open sampling
strategies which are basically test
components for you to start your douse
your centralized applications just
running a couple of minutes so the
components of the surrogates are the
open something contracts which you all
probably know oneself in a security that
we have been talking about if you are
for connecting to a network a one-liner
killer one-liner web 3 adapter that you
can use to avoid the cumbersome process
of you know developing the first part of
free reaction rules for managing your
front-end web components and the open
supplement load which is the super cool
- we developed that will let you modify
your contracts on the go and after
saving them you will be able to see in
your website those changes I mean if you
have something Brigantine lying to save
your contract with a different API we
will be able to see that same
information the information within your
website use each piece against super
easy with the CLI running open something
on my starter or opens up in combat
tutorial will do the trick
being starter the starter kit which will
let you start a project from scratch and
toriel a simple demo
how to use the CLI 'when two super
useful examples of our counter on AVM
packages you can regard going to sell
things / storing it slip assembling /
sdk and the salt thank you very much
[Applause]
