Deposit

To make a deposit into the vault, use the deposit method. Here are the steps to create the transaction:

1. Prepare parameters:

   • amounts_desired: A vector specifying the desired quantities of each asset you wish to deposit.

   • amounts_min: A vector specifying the minimum quantities of each asset to be transferred from the source for each asset.

   • from: The address of the user making the deposit. Represents a Soroban address.

   • invest: A boolean indicating whether the deposited funds should be automatically invested in the vault's strategies (true) or remain as idle_funds (false).

2. Example transaction:

   {
     "method": "deposit",
     "params": {
       "amounts_desired": [1000],
       "amounts_min": [900],
       "from": "GCINP...",
       "invest": true
     }
   }

Deposit Request

{
    amounts: [10000000],     // Array of amounts for each vault asset (7 decimals for XLM)
    caller: userAddress,     // User's wallet address
    invest: true,           // Auto-invest into strategies (recommended: true)
    slippageBps: 50         // 0.5% slippage tolerance (optional, default: 0)
}

Deposit

Deposits funds into the DeFindex vault.

const vaultAddress = 'CAQ6PAG4X6L7LJVGOKSQ6RU2LADWK4EQXRJGMUWL7SECS7LXUEQLM5U7';

async function deposit(amount: number, user: string, apiClient: ApiClient, signerFunction: (tx: string) => string) {
    // Step 1: Request an unsigned transaction from the API
    const { xdr: unsignedTx } = await apiClient.postData("deposit", vaultAddress, {
        amounts: [amount],
        from: user
    });

    // Step 2: Sign the transaction (implement your own signer)
    const signedTx = signerFunction(unsignedTx);

    // Step 3: Send the signed transaction back to the API
    const response = await apiClient.postData("send", vaultAddress, {
        xdr: signedTx
    });
    return response;
}

Deposit to Vault

Add funds to a vault:

const depositData: DepositToVaultParams = {
  amounts: [1000000, 2000000], // Amounts for each vault asset
  caller: userAddress,
  invest: true, // Automatically invest after deposit
  slippageBps: 100 // 1% slippage tolerance
};

const response = await sdk.depositToVault(vaultAddress, depositData, SupportedNetworks.TESTNET);
// Sign response.xdr with the caller account and submit transaction
