Compile, test, deploy, and interact with smart contracts
Project description
Cupcake
Easily compile, test, and deploy smart contracts
Cupcake is a development enviroment to compile, test, and deploy Ethereum smart contracts. It automates the process down to a few lines of code for most complex operations, while continuing to maintain versatility. The built-in network makes testing just work without any additional setup. Optionally, Ganache can easily be used as a provider.
Interact with existing contracts and send ether
Cupcake comes with a scripting workspace for sending ether and interacting with other smart contracts on the blockchain.

account(provider)
The account function will convert a private key into a public key without any parameter argument or derive accounts from the provider. Returns key_pair account()
and public key account()[1]
from the private key in .env or public addresses from a provider as account(provider)[1]
through account(provider)[9]
.
compile(source)
Optionally set source argument to return object. Compiler outputs contract ABIs to build/
. Runs Install()
before compiling. Returns the source bytecode compile()[0]
and source ABI compile()[1]
only if the source argument is set.
contract(provider, address, abi)
Access an existing contract by giving a provider, contract address, and the contract's ABI. Returns contract
object.
deploy(source, constructor, provider, key_pair)
Will compile(source)
contracts and deploy contracts from the provider. Optionally use an array of constructor arguments. Use account()
for the optional key_pair
parameter. The first address from the provider is used if no key_pair
are provided. Returns contract
object.
install(version)
Installs version of Solidity or latest version if not argument is not set.
provider(type)
"Custom"
and "Ganache"
are type
arguments. "Custom"
and "Ganache"
types are defined in config.yaml. Use the built in local network with provider()
.
read(contract, function, args, expect)
Use contract()
or deploy()
for the contract
argument. Specify the function
as a string. Optionally use args
for the contract function arguments. Optionally use the expect
argument to override the return.
send(provider, to, amount, gas, sender, key_pair, chain)
Sends ether from an account. Use account(provider)[1]
for the sender
or use account()
for the key_pair
. Using key_pair
does not require the sender
argument. Use gas
and chain
only if key_pair
is used. Supported chain
string arguments are "mainnet"
, "ropsten"
, "kovan"
, and "rinkeby"
. If no chain
is provided, the Ethereum mainnet is used. Logs transaction hash to txs/
. Returns transaction hash
.
write(contract, function, args, value, gas, caller, key_pair, provider)
Use contract()
or deploy()
for the contract
argument. Specify the function
as a string. Optionally use args
for the contract function's argument. Optionally use value
if function requires ether. Use caller
or use gas
, key_pair
and provider
depending on the setup. Logs transaction hash to txs/
. Returns transaction hash
.
Add private key
Create .env file in project folder
touch .env
Add the private key to PRIVATE_KEY in the .env file and include 0x
PRIVATE_KEY=0x...
Enable Ganache
Add Ganache host and port in config.yaml
Network:
Ganache: http://127.0.0.1:7545
Set the provider(type)
to Ganache
provider("Ganache")
Return automated messages
Use msg("baked")
or msg("frosted")
to return success messages. Use msg(public_key=public_key, contract=contract)
to return deployment message. Use msg(tx=tx)
to return transaction message.
Convert ETH to WEI
Use eth(value)
to convert ETH to WEI
Load ABI from json file
Use source(abi/contract.json)
to return ABI
Set gas limit
Add the following to config.yaml
Gas:
Limit: 200000
Change the .env file path location
Add the following to config.yaml
Key:
Location: "path/.env"
Change config.yaml network names
Change the config.yaml custom network name to enable provider("Infura")
Network:
Infura:
Print with color
Use p(object)
to print()
with color
Disable Colors
Add the following to config.yaml to disable colors
Colors:
Disable: True
