Actions

Depositing Tokens

To deposit tokens (e.g., USDT0) into the dnPUMP vault, you must interact with the Insurance Contract.

Steps:

1. Approve Spending:

   • The user must approve the Insurance Contract (0xaF8FfEDF0e57eE9f6518340b9eb913fFa7dBc66b) to spend the chosen deposit token (e.g., USDT0).

   • Call the approve(address spender, uint256 value) function on the chosen deposit token's contract.

     • spender: The Insurance Contract address.

     • value: The amount to approve, in the token's native decimals (e.g., 6 for USDT0).

2. Perform Deposit:

   • Once approved, call the depositInstant function on the Insurance Contract.

   • depositInstant(address tokenIn, uint256 amountToken, uint256 minReceiveAmount, bytes32 referrerId)

     • tokenIn: The address of the token being deposited.

     • amountToken: IMPORTANT: The amount to deposit, expressed in 18 decimals, regardless of the input token's actual decimals.

       • For tokens with 18 decimals (like USDe), use the amount directly.

       • For tokens with fewer decimals (like USDT0 with 6), you must scale the amount. For example: amountIn18Decimals = amountIn6Decimals * 10**(18 - 6).

     • minReceiveAmount: The minimum amount of dnPUMP to receive. Can be set to 0 to accept any amount.

     • referrerId: A bytes32 referrer ID. Can be set to 0x0000000000000000000000000000000000000000000000000000000000000000. or enter your referrerId from our collaboration.

Withdrawing Tokens

To withdraw underlying assets (USDT0) in exchange for dnPUMP, you must interact with the Redemption Contract. There are two methods: Instant and Classic.

Step 1 (Required for both methods): Approve

• Before withdrawing, the user must approve the Redemption Contract (0x9c915C94066fF921264071aCB7D59DB6e0cBf0D7) to spend their dnPUMP.

• Call the approve(address spender, uint256 value) function on the dnPUMP Vault Token contract (0x8858A307a85982c2B3CB2AcE1720237f2f09c39B).

  • spender: The Redemption Contract address.

  • value: The amount of dnPUMP to approve (in 18 decimals).

Step 2 (Option A): Instant Redeem

• For immediate withdrawal, subject to a 0.5% fee.

• Call redeemInstant(address tokenOut, uint256 amountMTokenIn, uint256 minReceiveAmount) on the Redemption Contract.

  • tokenOut: Address of the token to receive (USDT0: 0xB8CE59FC3717ada4C02eaDF9682A9e934F625ebb).

  • amountMTokenIn: Amount of dnPUMP to withdraw, in 18 decimals.

  • minReceiveAmount: The minimum amount of the output token to receive. Can be set to 0.

Step 2 (Option B): Classic Redeem

• For withdrawal processed within 48 hours with no fee.

• Call redeemRequest(address tokenOut, uint256 amountMTokenIn) on the Redemption Contract.

  • tokenOut: Address of the token to receive (USDT0: 0xB8CE59FC3717ada4C02eaDF9682A9e934F625ebb).

  • amountMTokenIn: Amount of dnPUMP to withdraw, in 18 decimals.

Additional Information

• Token Balance (BalanceOf):

  • To get a user's balance for any of the deposit tokens, call balanceOf(address account) on that token's contract.

  • To get a user's hbUSDT (vault shares) balance, call balanceOf(address account) on the hbUSDT vault contract.

• Withdrawal Processing Period (Classic): Classic redemption requests will be processed within 48 hours. The assets are automatically sent to the user's wallet upon processing.

• Checking Withdrawal Status (Classic): Unlike the August vaults, status for classic redemption requests is checked via an off-chain API provided by Midas, not a smart contract function. API Endpoint: GET https://api-prod.midas.app/api/data/requests/pending?address=<USER_ADDRESS>&networkId=999 Replace <USER_ADDRESS> with the user's wallet address. The API will return a JSON object containing a redemptions array. Each object in this array represents a pending withdrawal request and includes details like the amount, creation date, and status (pending, ready, or expired).
