Share Price Mechanics​

How Share Price Changes​

Share Price = Total Vault Assets / Total Shares Outstanding

Example:

  • Vault has $1,050,000 USDC
  • 1,000,000 shares exist
  • Share price = $1.05

When Price Updates​

  • After each profitable trade
  • After management fee accrual
  • Real-time, not daily

Slippage Protection​

  • Large withdrawals may have price impact
  • Vault maintains liquidity buffer
  • No slippage for normal-sized withdrawals

SDK Integration​

For programmatic deposits/withdrawals, see the SDK Documentation.

import { SevenNSevenD } from '@7n7d/sdk';

const client = new SevenNSevenD({ ... });

// Deposit
await client.vault.deposit('1000'); // 1000 USDC

// Withdraw
await client.vault.withdraw('500'); // 500 USDC worth

Troubleshooting​

"Insufficient Balance"​

  • Check USDC balance on Arbitrum
  • May need to bridge from other network

"Insufficient Allowance"​

  • Need to approve USDC spending
  • Click approve button first

"Transaction Failed"​

  • Check you have ETH for gas
  • Try increasing gas limit
  • Wait and retry if network congested

"Withdrawal Too Large"​

  • Vault may have liquidity constraints
  • Try smaller amount
  • Contact support for large withdrawals
