Deploy Your ArrakisV2 Vault

Now we run a command to initialize a private ArrakisV2 Vault on the DAI/WETH token pair and deposit an initial 1 DAI into the vault:
yarn tutorial1-init --network goerli
Congrats! You instantiated a private ArrakisV2 vault. At the end of the script you should see the address of your newly created DAI/WETH vault:
console readout
Copy and keep this vault address and you are ready to move on.

What Does This Script Do?

Notice that 4 transactions were done to initialize a vault in the "private" setting:
  1. 1.
    deployVault : called on the ArrakisV2Factory this deploys a fresh vault instance (sets initial vault params, for instance your EOA as the vault's owner and manager).
    const tx = await arrakisV2Factory.deployVault(
    feeTiers: feeTiers, // [500, 3000]
    token0: token0, // DAI token address
    token1: token1, // WETH token address
    owner: userAddr, // your address
    init0: init0, // 1 DAI
    init1: init1, // 0 WETH
    manager: userAddr, // your address
    routers: [], // no swap routers
    true // isBeacon = true (beacon proxy)
  2. 2.
    setRestrictedMint : called on the ArrakisV2 vault contract by the vault owner this restricts who can call the vault's mint function to a single address (your EOA), rendering the vault "private" (without this, anyone can add liquidity into your vault and mint vault shares).
    const tx2 = await vaultContract.setRestrictedMint(
    userAddr // your address
  3. 3.
    approve : called on the DAI token contract this approves 1 DAI to be transferred to the vault in the subsequent step.
    const tx3 = await daiTokenContract.approve(
    vault, // vault address
    oneDai // 1 DAI
  4. 4.
    mint : called on the ArrakisV2 vault, this mints the initial ArrakisV2 shares and deposits 1 DAI (because of #2, this only works from your address).
    const tx4 = await
    oneDai, // 1 DAI
    userAddr // your address (recipient)
