hello everyone uh my name is fuk Tha I'm
from Sky M so today I'm going to talking
about uh how to uh from NPC wallet to
fraction so I think from the previous
talk uh we already understand that uh
the there is a lot of issue with the
current EA is that it's were too complex
for uh some non non- Technical and even
technical users uh there's in Access
inacessible uh Rec recovering
mechanisms uh so uh to solve this
problem we had um a few solution in
place already and uh I going to want to
highlight two uh uh main thing is uh MPC
wallet and a Direction so both of them
can offer uh a lot of help with uh
onboarding new users offer soci Lo uh op
uh key Rec recovery and some uh trans
and policy so the difference between
NPCs and account rection is uh most of
the thing uh MPC do a on the offchain
including uh uh kre and transion policy
wise on account ctions uh it have uh
more transparencies and everything can
happen on chain and with account rection
we can also uh do uh have more user can
also have more flexibility in uh a lot
of uh feature for convenience sucess uh
batching generation gas sponsors uh and
Automation and uh something uh but um a
is Rel relatively new compared with the
MPC Tech techologies is is uh 40 Old
technology already and uh it ready to be
adopt right
now
so uh yeah uh so the the pro one of the
problem with MPC that um users uh user
cannot have the Eno the flexibility uh
that account offer but um with the int
introduction of 77 to uh we can uh
actually combine it with MPC to uh offer
a great have uh so this is a picture
from uh vitalic blocks that as we can
see here uh with MPC and
7702 we can aeve most of the goal uh all
the convenient go that ACC still uh can
be acch and some of the security goal uh
so suest like here we can see that that
U automation can be done uh if we can uh
delegate the the the the E to uh some uh
the the Kissa that store on the server
uh uh G attractions uh sponsoring uh
bass and everything so so the reason
that uh 7702 can be a great combinations
with MPC wallet is that uh the current
infrastructure of MPCs uh already in
plate that can have uh with the sum of
the feature of
7702 uh so one of the key thing I want
to highlight here is that the privilege
the escalation that uh in NPC we had uh
multiple Kat that store in the user
device in the server uh that we already
had a system in place for this and with
7702 we can uh we can set the MPC
account to uh to set code for that
account to enable uh
delegation saw some access to the Keat
that in either in the client uh device
or in the the server that can do uh some
of the uh some of the uh operations that
user can do day
to-day and so another another thing that
I want to mention here is that uh one of
the problem with current MPC is that uh
when we select a thread hole for uh NPC
we usually need to invol a trade off for
example if we use like two two out three
threat hole some can be side without the
user knowing but if we use two out2
threat Hole uh then if the every trans
need to be Side by user but uh the user
uh it the key cannot recover recover if
the user lost their sh the key shot and
they have not have any back up so uh
with the 7702 we can introduce a time
lock on chain key recovery that uh we
can had uh uh either keyot can be
uh gain full access to the to the wallet
if it initiate a trans and then the the
other one do not have challenge that in
let's say 30 di
peros so I think that's that it for
everyone thank
you thank you fuk we have some time for
questions so raise your hand if you want
to ask a question and I'll get the the
box to
you or if you're further in the back a
colleague of mine will do
it I know you want to know things this
is your
CH if not then I'll ask a question and
trust me you don't want to hear my
questions they're they're not going to
be that
good okay well I'll still do it um if
you want people to come away from this
with one thing and start implementing
that in their work what would that
be can you can you elaborate that a
little bit so we all go back home after
Devcon and you want people to do one
thing what's the thing that you want
people to do uh so I think the thing I
want people to do is to push our 7702 as
soon as
possible yeah cool
cool anyone have a
question or shall we call it
today yes amazing all right I think I
can do it
maybe yeah okay and one and two
and ah
almost okay so my question is uh a
little more on the gas abstraction part
I I know MPC wallets can be um connected
to AA wallets and um yeah uh my question
is is is there another solution that is
more sustainable compared to just
sponsoring the gas for for every
transaction yeah can you can you
elaborate it a little bit uh yeah so
some some wallets because uh the most of
the non- Crypton native users don't have
a concept of gas that they have to pay
for each transaction uh a lot of
protocols and applications sponsor this
gas so that the user can uh can continue
with uh with using the application and
the way they do it is that they the pay
master and that pay Master uh pays for
the user transaction fees and uh yeah my
question is how are there any solutions
that you think can make this um this
sustainable for the
applications so I think
uh so that is a good question but I I
think uh the the sponsor so this is uh
come from that if the the app uh
developer that they want to be more
convenience for the user so they want to
uh onboard more users so one of the
thing they can do is that they can ease
out the onboarding process and pay for
the gas for the user so I think that can
be great have in in this
case all right uh that's all the time we
have for questions thanks again folk
give it up for fuk for the wonderful
talk
