Important Details
7-Day Withdrawal Window
- Withdrawals are a two-step flow: request, then complete after 7 days
- The window is enforced on-chain by the vault contract
- No additional exit/withdrawal fee beyond the standard fees disclosed above (the 0.5% annual management fee and 10% performance fee still apply); requests can be cancelled at any time before completion
Processing Time
- Deposits: Instant (1 block confirmation)
- Withdrawal requests: Instant (1 block confirmation)
- Withdrawal completion: available 7 days after the request
Minimum Amounts
| Action | Minimum |
|---|---|
| Deposit | No minimum (consider gas) |
| Withdraw | No minimum (consider gas) |
| Recommended | $100+ to justify gas costs |
Gas Costs
Typical Arbitrum gas costs:
- Approval: ~$0.10
- Deposit: ~$0.20
- Withdraw: ~$0.20
Gas costs vary with network congestion
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
- If your USDC is on Ethereum or Base, use Cross-Chain Deposits to deposit directly via Circle CCTP
"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
