Hi,
everyone
welcome
to
another
session
of
core
units
tour.
Today
we're
going
to
go
through
sablier.
We
have
paul
rosenberg
here
from
from
the
team
and
he's
going
to
walk
us
through
and
hopefully
answer
all
of
our
questions
again,
if
you,
if
you
want
to
interrupt
at
any
point,
feel
free
and
and
yeah
paul.
If
you
want
to
give
a
quick
introduction
of
of
who,
you
are
sure.
B
B
In
the
meantime,
we've
been
acquired
by
by
hi-fi,
which
is
a
fixed-rate
landing
protocol,
also
in
ethereum,
and
I'm
now
part
of
the
you
know
hifi
team,
but
we're
we
are
also
maintaining
subjects
like
a
public
good
as
a
product
that
anybody
in
in
d5
and
ethereum
can
use
and
yeah
I
mean
it's
still
going.
We
have.
We
have
quite
a
few
users
and
I'm
I'm
very
happy
to
be
here
to
to
present
it.
B
A
B
Yes,
so
what
you're
seeing
here
is
our
stream
creation
page?
It's
a
dashboard
where
you
can
see
all
the
streams
that
you
created
and
the
the
the
way
somebody
works
is
that
you
you
go
through
this
stream
money
button
and
then
you
have
this
the
sidebar
here
and
you
will
have
to
deposit
to
lock
a
specific
amount
of
money.
B
That's
going
to
be
streamed
over
a
specific
duration
and
then,
after
the
moment
you
create
it
on
this
page.
It
will
start
every
second
allocating
a
small
amount
of
money
to
the
recipient
and
that's
money
streaming.
It's
money
streaming
at
the
smart
contract
level
because
the
money
is
trustlessly
held
in
our
in
our
smart
contract,
and
this
is
where
you
can
create
it.
B
So
let
me
go
ahead
and
I'm
gonna
use
rinkaby
to
save
on
yes
and
I'm
gonna
use
it
like
a
testament
version
of
die
and
let's
say
that
one
of
the
more
common
use
cases
is.
You
have
an
employee
that
is
remote
abroad
and
you
know
you
want
to
pay
them
in
real
time,
not
like
monthly
or
bi-weekly,
because
that's
so
you
know
it's
a
web
2.
in
in
in
web
3.
You
can
do
this
like
every
second
right,
so
let's
say
you
want
to
pay
them.
B
Solutions,
I
think
it's
a
coordination
problem
right
now
where,
where
everybody
is
like,
what
is
the
next
person
gonna
do,
and
you
know
I
think
we
have
to
wait
for
the
big
exchanges
to
make
the
first
move
and
then
we
will
follow.
But
at
the
moment
there
is
a
community
built
version
of
something
using
the
same
contracts
and
same
almost
same
ui
on
xdi.
B
B
Yes,
yes,
this
is
the
current
behavior
and
you
could
imagine
doing
something
like
you
know,
patches
of
streams
where
once
every
three
months
or
like
once,
every
six
months,
you
deposit
the
money
here
and
then
it's
it's
still
thrown
by
the
second.
But
you
as
a
creator.
You
just
batch
these
transactions
over
over
time.
Another
option
which
is
more
interesting,
is
you:
could
you
could
deposit
compound
die
and
there
is
an
option
to
keep
the
interest
to
yourself.
B
A
A
B
And
let
me
go
ahead
and
create
a
stream,
and
then
we
can
see
how
you
can
cancel
and
withdraw
from
one
stream,
because
you
do
have
that
ability.
So
after
the
stream
is
created.
Let's
say
that
you
know
ten
days
pass
well
ten
days
times,
one
hundred
per
day
that
gives
one
thousand
so
you
will
be
getting
back.
Nine
thousand
and
the
employee
will
be
receiving
one
thousand
yeah,
so
nine
and
and
one
and
that's
just
the
allocation
that
was
streamed
over
the
first,
the
first
10
days
but
yeah.
B
B
Time
so
yeah
I
created
a
stream.
There
is
a
small
delay
after
it
gets
created.
It
starts
now,
so
it
will
start
in
five
minutes,
there's
a
buffer,
so
we
account
for
the
time
it
gets
to
to
process
the
transaction
on
on
ethereum
maintenance.
But,
as
I
said,
if
you
go
to
the
creator
page,
which
is
this
pay,
there
is
a
cancel
button
on
the
right
hand
side.
So,
if
you
were
to
cancel
this,
you
would
get
at
this
point
in
time
all
the
money
back.
C
B
We
have
our
gas
costs
on
on
our
documentation
and
I
can't
tell
off
the
top
of
my
head.
But
let
me
let
me
open
it
and
check
here
so
yeah,
it's
like
250
to
create
a
stream
and
then
for
every
action.
It
takes
90k,
withdraw
so
relatively
cheap
for
for
the
receiver
to
withdraw
to
claim
the
money.
But
if
you
want
to
cancel,
then
there's
one
120k
and
if
you
want
to
create
it,
it's
250
which
I
think
a
pretty
reasonable
cost
compared
to.
B
A
Okay,
I
was
wondering
how
it
worked
from
from
a
technical
point
of
view.
I
guess
that
you
that
the
the
dye
doesn't
move
from
from
the
smart
contract.
It
just
changes
ownership,
so
you
potentially
have
two
pools
and
you're
changing
ownership
block
to
block
or
minute
to
minute,
I'm
not
sure,
and
then
the
the
employee
has
the
withdrawal
rights
on
on
one
of
the
blocks,
the
receiving
one
and
then
the
other
one.
B
That's
the
idea,
yes,
and
you
can
think
of
this
as
like-
a
very
short-termed
smart
contract
wallet
that
keeps
accruing
money
for
for
users
and
then
when
the
stream
is
ended.
Basically
the
the
smart
contract
wallet
gets
terminated
in
a
very
technical.
You
know
terms
here,
but
yes
like
that,
that's
one
good
way
to
put
it
and
yeah
go.
A
A
B
A
D
Well,
that's
super
cool,
so
you
could
actually
use
this
also
for
streaming
residual,
maybe
like
nft
royalties
right.
So
if
somebody
puts
out
a
nft
and
they're
doing
it
already
like
one
of
the
dj's
is
selling
one,
I
can't
remember
his
name
but
anyway,
so
you
can
actually
get
streams
for
royalties
with
the
1620.
B
I
I
don't
see
why
that
couldn't
happen.
In
fact,
I've
seen
a
startup,
it
was
like
2020.,
they
were,
they
were
doing
some
sort
of
like
landing
platform
for
nfts,
where
they
were
using
subjects
to
stream
the
royalty.
So
it
can
happen,
there's
nothing
that
stops
you
from
using
this
in
your
own.
You
know
nf2
protocol,
so
yeah
totally
doable.
Yes,
I
think
we
can
go
and
even
more
complex
layer
here
and
make
the
streams
themselves
a
non-definable
token.
B
D
B
Yeah
or
you
could
look
it
up
in
like
a
credit
protocol
and
maybe
get
a
loan
on
that
it's
sort
of
like
under
collateralized.
In
a
sense
I
mean
it
depends
on
how
much
you're
getting
if
you're
getting
the
loan
in
real
time
as
well.
But
yeah
I
mean
certainly
interesting.
Things
can
happen
if
we
tokenize.
This
is
not
functional
tokens
for
now.
There's
no
implementation
by
us
for
this,
but
it's
on
our
ladder.
C
B
B
One
good
example
is
m
stable,
who
literally
put
all
of
their
investor
money
in
in
salvia
and
all
of
their
investors,
from
from
you
know,
from
germany
from
the
us
they're
all
on
the
same
platform
here
and
claiming
they
are.
You
know
their
return
on
on
investment
for
sub
years.
So
it's
definitely
long
term
from
that
perspective.
B
But
I
would
suppose
that
also
gas,
yes
matters
here,
because
you
know
if
even
if
it
would
be
more
kind
of
like
easier
from
an
iconic
perspective
to
do
like
monthly
streams.
The
gas
costs
add
up.
So
it's
easier
to
just
do
like
one
year,
long
stream
and
one
good
example
for
this
is
sushi,
swap
who
I
I
think,
in
september
or
october,
they
they
did
like
a
a
one
year,
long
stream
to
all
of
their
employees,
and
that
was
usdc.
B
B
A
B
B
So
gnosis
has
been
a
huge
like
avenue
for
us
to
get
more
users
and
in
the
future
we
are
we're
looking
to
to
get
started
listed
on
more,
maybe
defy
indexers,
because
now
we
are
not
listed
on,
maybe
like
d5
pills
or
things
like
that.
Even
if
we
do
have
a
reasonable
amount
of
of
tvl
total
value
locked.
But
I
think
we
are.
B
B
Organization
that
that
owns-
and
you
know
xavier
is-
is
hifi
and
we
do
have
a
governance
token
for
our
lending
protocol
there,
but
they're
not
related.
You
know.
Subjer
is
just
like
this.
This
payments
app-
and
I
think
I
think
it's
it's
certainly
in
the
middle
as
in
it's
not
like
this
wildly
successful
d5
protocol
like
maker,
of
course,
but
it's
not
it's
not
that,
and
it's
not
going
to
be
that
anytime
soon.
B
E
Yeah,
I
guess
the
thing
that
I'm
wondering
about
is
at
like
as
a
a
would-be
core
unit
facilitator
like
we're,
going
to
be
paying
people
out
using
opolis
right
and
I'm
curious.
If
the
people
that
are
you
know,
contributors
that
want
to
take
crypto
payments
if
they
want
to
accept
crypto
payments
from
opolis,
I'm
wondering
if
opolis
would
would
pay
them
out
through
sablier.
Like
do
you
guys,
have
any
conversations
with
them
and
other
like
crypto
payroll
providers,.
A
B
Dimension
of
of
you
know
where
cryptomites
meets
the
law
right.
There
have
been
some
experiments
in
this
in
this
way.
If
you
know
ross
campbell
from
formerly
called
the
lao
he
was,
he
was
doing
some
experiments
where
he
attached
like
a
pdf
that
was
encoding
in
a
smart
contract.
That
was
a
legal
representation
of
like
a
a
freelancer
contract
that
was
paid
through
sabir.
B
A
E
B
That
is
true,
although
there
are
ways
in
which
you
can
implement
this,
that
could
be
plugged
into
like
a
time
tracking
software,
if
you
think
about
something
like
zendesk,
where
you
have
like
this
customer
support
staff
that
you
know
they
log
in
and
blog
off
very
frequently.
Well,
you
could
theoretically
start
the
stream
every
time,
those
support
stuff
log
in
and
then
there's.
B
B
E
No,
I'm
I'm
honestly,
I'm
just
thinking
about
practically.
You
know
like
if,
if
I
as
a
facilitator,
want
to
offer
this
to
you
know
members
of
our
team,
like
you
know
what
what
hoops
do,
I
have
to
jump
through
or
like
what
should
I
be
considering
like
what
are
my
options?
What's
the
easiest
way
to
do
it
like
those
are
all
the
questions
that
are
going
through
my
mind,
yeah.
E
This
into
toggle
and
like
have
it
so
that
all
right,
you
know
like
every
single
hour
that
they
register
on
their
toggle.
It
just
like
automatically
changes
the
the
stream
configuration
and
like
they're,
able
to
get
that
hour,
pretty
much
immediately
stream
to
them
right,
like
even
as
they
work
potentially
like
if
there's
low
enough
latency
with
integration
but
but
yeah.
It
sounds
like
there's
a
lot
of
potential,
but
there
needs
to
be
like
more
tooling.
That
would
make
it
easier
for
for
people
like
me.
B
I
agree
we
there's
a
long
way
to
go
before
this
is
really
bulletproof
for
payroll,
but
I
guess
it's
a
question
of
like
optimization
versus
being
very
generic
like
generic,
and
we
kind
of
like
try
to
keep
the
protocol
and
and
and
product
generic
in
the
in,
in
the
sense
that
it
can
be
used
for
fasting.
It
can
also
you
be
used
for,
like
this
very
defy.
B
C
E
Actually,
that's
it.
That's
a
good
point
like
if,
if
let's
say
we
were
to
stream,
not
to
employees
as
compensation,
but
rather
to
to
core
unit
treasury
wallets
right
just
for
you
know,
instead
of
doing
like
a
monthly
payment,
maybe
the
budget
implementation
would
be
a
stream
like
that's
an
option
right.
That
would
be
cool.
B
E
B
B
B
E
B
B
We
do
have
some
very
interesting
ideas
for
solving
the
like
having
to
lock
up
the
money
problem
where
you
can
create
a
stream
without
having
to
to
to
put
in
everything
for
the
whole
period,
so
that'll
be
the
main
highlight
in
terms
of
like
a
road
map
and
certainly
layer,
two
just
because
it'll
be
it.
It
really
becomes
unbearable
for,
for
many
of
our
users
to
you
know,
just
make
a
payment.
It's
fifty
dollars
so
layer
two
and
solve
the
lookup
problem.
A
B
I
mean
we
are
actually
developing
the
so-called
version,
one
of
hi-fi.
For
now
we
have
like
a
public
beta.
I
can't
give
an
estimate
for
that.
It's
gonna
be
relatively
soon
this
year,
but
I
I
can't
give
an
estimate.
Yes,
we
are
working
on
on
making
the
the
market
making
much
better
for
our
fy
tokens
for
our
essentially
bonds.
B
A
B
B
B
You
just
stay
there
for
like
five
hours
and
then
you
go,
and
I
I
wonder
you
know
to
what
extent
a
world
in
which
one
is
streaming
is
really
recognized
as
as
a
money
primitive
to
what
extent
the
world
changes
around
that,
as
in
does
the
pricing
for
for
renting
become
better
or
not?
Does
it
become
different?
Is
the
world
more
fluid?
B
A
B
We're
on
twitter,
so
that's
the
main,
the
main
stage.
It's
saved
your
hq
and
also
on
discord.
The
link
is
on
twitter
and
same
for
for
hifi.
This
is
our
main
avenue
for
social
interactions.
It's
twitter
and
discord
hope
to
see
you
there
and,
of
course,
our
website
is
subwoofer
finance.
If
you
want
to
use
the

and
then
you
will
be
given
the
