Locklift is a development environment aiming to help you with TVM contracts development. With Locklift, you get:

• Network management for working with any networks (main, test, local, ...)
• Automated contract testing with Mocha
• Handy wrapper around TVM smart contract
• Custom givers support
• Keys management
• External script runner that executes scripts within a specified environment

Quick start

To install Locklift you need node 14 or later. Go to an empty folder, initialize an npm project (i.e. npm init), and run

npm install --save-dev locklift

Once it's installed you can initialize the project

// initialize in current directory
npx locklift init -f
// or specify new one
npx locklift init --path amazing-locklift-project

Get version

npx locklift --version

CLI docs

This section describes the set of commands, supported by the locklift package.

Initialize Locklift package

npx locklift init --path amazing-locklift-project
# New Locklift project initialized in amazing-locklift-project

This command initializes new Locklift project, filled with samples:

├── contracts
│   └── Sample.sol
├── locklift.config.ts
├── scripts
│   └── 1-deploy-sample.ts
└── test
    └── sample-test.ts

Other flags

-f, --force - force run the init command (in case you have any files in the target directory);

Configuration

By default, the configuration file is called locklift.config.ts. Here's the basic layout:

const config: LockliftConfig = {
  compiler: {
    // Specify path to your TON-Solidity-Compiler
    // path: "/mnt/o/projects/broxus/TON-Solidity-Compiler/build/solc/solc",

    // Or specify version of compiler
    version: "0.61.2",

    // Specify config for extarnal contracts as in exapmple
    // This filed for generating types only
    // externalContracts: {
    //   "node_modules/broxus-ton-tokens-contracts/build": ['TokenRoot', 'TokenWallet']
    // }

    // Additional comiler params can be added via this field
    // compilerParams: ["--tvm-version ton"],
  },
  linker: {
    // Specify path to your stdlib
    // lib: "/mnt/o/projects/broxus/TON-Solidity-Compiler/lib/stdlib_sol.tvm",
    // // Specify path to your Linker
    // path: "/mnt/o/projects/broxus/TVM-linker/target/release/tvm_linker",

    // Or specify version of linker
    version: "0.15.48",
  },
  networks: {
    locklift: {
      blockchainConfig: "TON", // or other presets, or we can provide our custom config by {cunstom: "MY BLOCKCHAIN CONFIG"}
      connection: {
        id: 1001,
        // @ts-ignore
        type: "proxy",
        // @ts-ignore
        data: {},
      },
      keys: {
        // Use everdev to generate your phrase
        // !!! Never commit it in your repos !!!
        // phrase: "action inject penalty envelope rabbit element slim tornado dinner pizza off blood",
        amount: 20,
      },
    },
    mainnet: {
      // Specify connection settings for https://github.com/broxus/everscale-standalone-client/
      connection: "mainnet",
      // Here, default SafeMultisig wallet is used as a giver
      giver: {
        address: "0:ece57bcc6c530283becbbd8a3b24d3c5987cdddc3c8b7b33be6e4a6312490415",
        // you can use bip39 phrase instead of key
        phrase: "action inject penalty envelope rabbit element slim tornado dinner pizza off blood",
        accountId: 0,
      },
      keys: {
        // Use everdev to generate your phrase
        // !!! Never commit it in your repos !!!
        // phrase: "action inject penalty envelope rabbit element slim tornado dinner pizza off blood",
        amount: 20,
      },
    },
  },
  // you can use any settings that mocha framework support
  mocha: {
    timeout: 2000000,
  },
};

Note about networks.locklift.blockchainConfig

This field is used to specify the blockchain config. It can be one of the following:

blockchainConfig: "EVER" | "TON" | { custom: string } | undefined;

For example we can get our blockchain config from explorers. Lets see an example of tycho config

• Open tycho-testnet explorer (config contract)
• Just coppy Data of this contract and paste it to networks.locklift.blockchainConfig.custom

Note about Giver settings:

Let's look at networks.giver this is giver settings filed. All known wallets and givers will be detected automatically e.g. EverWallet or GiverV2 (from local node). You only need to provide giver credentials - (address, secret key, or phrase with account id). But if you want to use something custom you will need to provide giverFactory callback for networks.giver.giverFactory that callback should return something that implements Giver interface

Getting code of contract

This command will show you the contract code

npx locklift code -c <contract name>

Getting storage fee of contract

This command will show you storage fee for the given period of time

npx locklift fee -a <contract address> -n main

Build contracts

This command uses the specified TON Solidity compiler and TVM linker to build all project contracts.

npx locklift build

Found 1 sources
Building contracts/Sample.sol
Compiled contracts/Sample.sol
Linked contracts/Sample.sol

Test contracts

This command runs the project Mocha tests, test folder by default. The locklift object will be set up and included automatically, you don't need to import it manually.

npx locklift test --network local

  Test Sample contract
    Contracts
      ✓ Load contract factory
      ✓ Deploy contract (1491ms)
      ✓ Interact with contract (1110ms)


  3 passing (3s)

Debugging

You can print to console in contracts with special library:

import "locklift/src/console.sol";

contract Sample {
  function testFunc(uint input) external {
    tvm.accept();

    console.log(format("You called testFunc with input = {}", input));
  }
}

Note: console.log functionality working only with tracing e.g:

await lockLift.tracing.trace(sampleContract.testFunc({ input: 10 }).sendExternal({ pubkey: keyPair.publicKey }));

And then you will see this in your terminal:

You called testFunc with input = 10

Note the console.log is just an event, so if your message dropped on the computed phase (e.g. required didn't pass), you will not see the log message.

Tracing

The tracing module scans the message tree, determines which contracts have been deployed, and decodes all method calls. In case of an error in some section of the execution graph, tracing will show the chain of calls that led to the error, as well as the error itself.

Note: If you want to use tracing be sure to provide a tracing endpoint to the config that supports graphql

// trace deploy
const {contract: deployedContractInstance, tx} = await locklift.tracing.trace(locklift.factory.deployContract(...))
// trace simple transaction
const changeStateTransaction = await locklift.tracing.trace(MyContract.methods.changeCounterState({newState: 10}).sendExternal({publicKey: signer.publicKey}))
// trace runTarget
const accountTransaction = await locklift.tracing.trace(myAccount.runTarget(...))

example with tracing output

npx locklift test -n local
