How to Run Your Own Ethereum Testnet using Anvil and Python?

In
the
Ethereum
blockchain,
the
role
of
Testnet
is
fundamental.
An

Ethereum
Testnet
is
basically
the
identical
copy
of
a

blockchain
network.
Its
sole
purpose
is
to
carry
out
testing
of
new
attributes
and
dimensions.
A
common
question
that
most

blockchain
developers
ask
today
is
–
‘How
do
you
get
Ethereum
for
testnet?’
It
is
an
important
question
that
you
need
to
find
an
answer
to
while
working
within
an
Ethereum
network.
Ethereum
blockchain
developers
rely
on
Ethereum
Testnet
for
testing
protocol
upgrades.
That’s
not
all!
By
using
Ethereum
Testnet
it
is
possible
to

test
smart
contracts
before
they
are
actually
deployed
for
users.
With
the
help
of
Aenvil
and
Python
you
have
the
option
to
run
an
Ethereum
Testnet
yourself.
Hence
you
do
not
need
to
go
through
the
typical
hassles
of
using
an
official
Testnet.
However
the
main
question
that
you
need
to
address
is
related
to
how
to
build
Ethereum
Testnet.
Let
us
explore
the
steps
that
can
help
you
create
Ethereum
Testnet
with
anvil
and
python.

Steps
to
Run
Your
Ethereum
Testnet
using
Anvil
and
Python

If
you
wish
to
create
Ethereum
Testnet
with
anvil
and
python,
you
need
to
adopt
a
systematic
and
step-by
step
approach.
The
below
steps
can
serve
as
the
ultimate
roadmap
in
your
journey
to
build
Ethereum
Testnet.
You
do
not
have
to
feel
overwhelmed
as
the
simple
instructions
can
guide
you
to
effectively
run
your
Ethereum
Testnet.

Step
1
–
Installation
as
well
as
Running
of
Anvil

The
first
step
that
you
need
to
take
involves
installing
and
running
Anvil.
In
case
you
have
limited
insight
into
Anvil
you
need
to
know
that
it
is
a
component
of
the
Foundry
toolchain.
It
is
a
basic
step
that
can
set
the
foundation
to
build
Ethereum
Testnet.

Are
you
wondering
about
Ethereum
development
with
anvil?
If
yes,
you
must
bear
in
mind
that
the
application
of
anvil
allows
you
to
get
started
with

Ethereum
development
in
a
straight-forward
manner.
There
are
a
few
sub-steps
that
you
need
to
follow
to
progress
in
your
first
step:

• 
  Sub-step
  1
  –
  Installation
  of
  Foundry

You
must
install

Foundry
so
that
you
can
use
its
anvil
component.
For
doing
this
you
need
to
open
the
terminal
and
run
the
appropriate
command.
Once
you
have
successfully
completed
the
installation
process,
you
need
to
source
Foundry
using
the
necessary
command. 

• 
  Sub-step
  2
  –
  Installation
  of
  Anvil

After
the
installation
of
the
Foundry
toolchain,
you
need
to
focus
on
Anvil.
You
have
to
install
as
well
as
run
Anvil
so
that
you
can
get
started
with
your
local

Ethereum
node.
You
can
be
sure
that
Anvil
is
running
if
you
see
the
output
indicating
the
same.
Moreover,
the
output
must
also
encompass
other
details
such
as
the
Remote
Procedure
Call
(RPC)
endpoint.

about
the
basic
concepts
of
Ethereum,
such
as
transactions,
addresses,
consensus,
blocks,
and
important
tools
with
the Ethereum
Technology
Course.

Step
2
–
Connecting
to
the
local
Anvil
Node 

It
is
now
time
to
focus
on
the
next
step
after
you
have
completed
the
first
step.
The
second
step
involves
setting
up
a
connection
with
the
local
Anvil
node.
At
this
stage,
it
is
essential
for
you
to
keep
in
mind
to
use
Python
as
the
programming
language.
In
order
to
interact
with
the
local
Anvil
Node
you
can
use

web3.py. 

Web3.py
is
a
Python
library
that
you
can
use
for
the
purpose
of
interacting
with
Ethereum.
Ethereum
development
with
python
will
simplify
your
journey
if
you
have
prior
insight
into
the
programming
language.
However
in
case
you
wish
to
use
other
programming
languages
such
as

Rust
you
can
do
so.

While
keeping
the
local
Anvil
Node
from
the
previous
step
running,
you
need
to
follow
the
below
sub-steps.
However,
it
is
important
to
bear
in
mind
that
you
must
perform
the
below
operations
in
a
new
or
separate
terminal
window. 

• 
  Sub-step
  1
  –
  Installation
  of
  web3.py

The
fundamental
step
that
you
must
perform
involves
installing
web3.py.

• 
  Sub-step
  2
  –
  Linking
  with
  the
  local
  Anvil
  Note

Once
you
have
successfully
installed
the
Python
library
it
is
time
to
connect
with
the
Anvil
Node.
For
doing
so
you
need
to
create
a
Python
script.
It
is
undoubtedly
a
key
process
that
can
help
you
to
establish
a
connection
with
the
Anvil
Node.

When
you
run
the
script,
if
everything
has
been
done
perfectly
and
correctly,
you
can
see
the
message
–
‘Connected
to
Anvil.’
This
message
will
be
displayed
in
your
terminal.
However,
if
you
fail
to
establish
the
connection,
you
have
to
recheck
the
Anvil
node.
This
step
is
crucial
so
that
you
can
make
sure
whether
the
local
Anvil
node
is
accurately
running
or
not.
Furthermore
it
will
also
help
you
see
whether
the
Anvil
node
is
effectively
logging
output
or
not.
These
are
a
few
key
things
to
bear
in
mind
if
you
wish
to
create
Ethereum
Testnet
with
anvil
and
python.

Step
3
–
Deployment
and
Interaction
with
a
Smart
Contract

The
third
step
is
undoubtedly
one
of
the
most
vital
steps
while
running
your
own
Ethereum
Testnet
using
Anvil
and
Python.
At
this
stage
you
need
to
focus
on
the
actual
deployment
aspects.
There
are
a
few
sub-steps
that
can
guide
you
to
effectively
navigate
the
third
step. 

• 
  Sub-step
  1
  –
  Creating
  a
  smart
  contract

You
need
to
start
by
developing
a
simple

smart
contract.
It
is
essential
to
bear
in
mind
that
the
purpose
of
the
smart
contract
is
just
for
testing.
Hence
it
has
to
be
simple.
You
can
use
a
new
name
for
the
same
and
add
the
appropriate

Solidity
code. 

• 
  Sub-step
  2
  –
  Using
  Forge
  for
  compilation
  and
  deployment
  of
  the
  contract

At
this
stage
you
need
to
compile
as
well
as

deploy
the
smart
contract.
You
can
do
so
by
using
Forge.
Firstly
you
must
open
the
terminal.
Then
you
have
to
navigate
through
the
directory
that
has
the
newly
developed
smart
contract.
After
running
the
necessary
command
you
will
see
that
the
smart
contract
gets
deployed
to
the
Anvil
Node.
An
important
thing
that
you
must
bear
in
mind
is
that
you
have
to
note
down
the
contract
address.
The
contract
address
is
the
one
that
has
been
generated
as
the
output
by
Forge. 

You
should
remember
that
when
the
deployment
of
a
smart
contract
takes
place
in
blockchain,
some
address
needs
to
pay
for
the
needed
gas.
The
specific
case
involves
local
Anvil
Node
and
local
Testnet.
Hence
there
is
an
option
to
make
use
of
any
of
the
default
accounts
that
have
been
developed
by
Anvil.
An
important
thing
to
consider
is
that
the
account
that
you
select
must
be
uniform
across
all
Anvil
runs.
However
you
may
require
to
utilize
another
address. 

• 
  Sub-step
  3
  –
  Interacting
  with
  the
  smart
  contract
  using
  web3.py

Now
you
need
to
develop
a
new
Python
script
that
will
support
interaction
with
the
contract.
During
the
deployment
step
you
must
ensure
that
you
use
the
actual
address
of
the
smart
contract.
It
is
an
important
thing
to
consider
when
you
create
Ethereum
Testnet
with
anvil
and
python.

After
you
run
the
script,
you
can
see
the
output
that
indicates
the
initial
value
as
well
as
the
value
that
is
generated
after
the
incrementation.
