Withdraw

Withdraw

To withdraw assets from the vault, use the withdraw method. Here are the steps to create the transaction:

1. Prepare parameters:

   • withdraw_shares: The amount of vault shares you wish to withdraw.

   • min_amounts_out: A vector specifying the minimum amounts required to receive before the transaction fails (tolerance). This amount is represented in underlying assets.

   • from: The address of the user performing the withdrawal, who will receive the funds. Represents a Soroban address.

2. Example transaction:

   {
     "method": "withdraw",
     "params": {
       "withdraw_shares": 500,
       "min_amounts_out": [450],
       "from": "GCINP..."
     }
   }

Withdraw

Withdraws funds from the DeFindex vault.

const vault = 'CAQ6PAG4X6L7LJVGOKSQ6RU2LADWK4EQXRJGMUWL7SECS7LXUEQLM5U7';

async function withdraw(amount: number, user: string, apiClient: ApiClient, signerFunction: (tx: string) => string) {
    const { xdr: unsignedTx } = await apiClient.postData("withdraw", vault, {
        amounts: [amount],
        from: user
    });

    // This should be done by implementer
    const signedTx = signerFunction(unsignedTx);

    const response = await apiClient.postData("send", vault, {
        xdr: signedTx
    });

    return response;
}

Withdraw from Vault

Remove funds by specifying amounts:

const withdrawData: WithdrawFromVaultParams = {
  amounts: [500000], // Specific amounts to withdraw
  caller: userAddress,
  slippageBps: 100 // 1% slippage tolerance
};

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

Withdraw by Shares

Remove funds by burning vault shares:

const shareData: WithdrawSharesParams = {
  shares: 1000000, // Number of vault shares to burn
  caller: userAddress,
  slippageBps: 100
};

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