CAST Tezos SmartContracts.

Diagram

Adding a Variable to a Smart Contract

1. Add the field to the storage of the Smart Contract (types.py):

T_forgeBondStorage = sp.TRecord(
    isinCode=sp.TString
)

2. Add the field to the viewMapper.ts file in cast-interface-v1. This file is shared with other blockchains, such as Tezos.

isinCode: async (storage: ForgeTokenStorage, methodParameters: unknown[]) =>
  storage.isinCode,

3. Deploy the changes. If the environment is already running, run the command make redeploy-tz. Otherwise, run the command make start.

Adding a Constant to a Smart Contract

1. Add the field to the viewMapper.ts file in cast-interface-v1. This file is shared with other blockchains, such as Tezos.

export const REGISTRAR_ROLE = 1;

2. Deploy the changes. If the environment is already running, run the command make redeploy-tz. Otherwise, run the command make start.

Adding a Function to a Smart Contract

1. Add the function to the Python file:

@sp.entry_point
def confirmPaymentTransferred(self, params):

    L_confirmPaymentTransferred = loadLambda(
        self.data.entrypointsBigMap,
        LAMBDA.CONFIRM_PAYMENT_TRANSFERRED,
        S_ConfirmPaymentTransferred
    )

    result = L_confirmPaymentTransferred(sp.record(
        txId=params.txId,
        sender=sp.sender,
        owner=self.data.owner,
        operatorsAuthorizations=self.data.operatorsAuthorizations,
        settlementTransactionRepository=self.data.settlementTransactionRepository,
    ))

    self.data.settlementTransactionRepository = result

    self.callEventSinkWithSettlementIdAndSettlementTransactionOperationType(
        settlementId=params.txId,
        settlementTransactionOperationType=OP.SUBSCRIPTION,
        eventName=EVENT.PAYMENT_TRANSFERRED
    )

2. Add the function to the TypeScript file in cast-interface-v1. This file is shared with other blockchains, such as Tezos.

public async confirmPaymentTransferred(
  confirmPaymentTransferredParams: ConfirmPaymentTransferredParams,
  transactionParams?: TransactionParams,
  transactionBlockchainSpecificParams?: Partial<
    BlockchainSpecificParamsOf<Driver>
  >,
): Promise<TransactionReceipt> {
  return this._send<[ConfirmPaymentTransferredParams]>(
    'confirmPaymentTransferred',
    [confirmPaymentTransferredParams],
    transactionParams,
    transactionBlockchainSpecificParams,
  );
}

3. Deploy the changes. If the environment is already running, run the command make redeploy-tz. Otherwise, run the command make start.

Installation

SmartPy

$ npm install
$ sh <(curl -s https://smartpy.io/dev-20200830-61244befe2c4c321c0ae6f807873e3a77811f20a/cli/SmartPy.sh) local-install-auto

Building

You need to first compile the contract and then the deploy script

Contracts

You need to have building command inside your smartPy contract. e.g. :

  sp.compile_contract(
    ForgeInstrumentRegistry(sp.address("KT1-eventSinkContractAddress")),
    target_directory = "dist",
  )

And then run it using SmartPy Cli

~/smartpy-cli/SmartPy.sh run ForgeInstrumentRegistry.py

Deploy script

Those are still a work in progress

Run npmr buildDeploy in cast-tz-v1, use node to run them.

To deploy a contract use node ./dist/originate ./path/to/directory

with the following file in the directory:

• contract_compiled.json
• constract_storage_init.tz

You can also use npm scripts :

• originateBondFactory
• originateBondBuilder
• originateEventSink
• originateInstrumentRegistry
