Opening:
- "Hello, I'm presenting the Collateral Vault Management System for GoQuant"
- "This is a comprehensive Solana-based solution for managing user collateral in a decentralized perpetual futures exchange"
Show Architecture Diagram:
- Display the system architecture from docs/architecture.md
- Explain the three main layers:
- Solana smart contract (Anchor program)
- Rust backend service
- PostgreSQL database
Key Features Overview:
- Non-custodial vault management using PDAs
- Support for deposits, withdrawals, and collateral locking
- Advanced features: multi-sig, security configs
- Real-time monitoring and analytics

Highlight Key Concepts:
- PDA-Based Vaults:
#[account(
seeds = [b"vault", user.key().as_ref()],
bump = vault.bump,
)]
pub vault: Account<'info, CollateralVault>,- Explain non-custodial design
- Program-controlled addresses
- SPL Token CPI:
token::transfer(
CpiContext::new_with_signer(
ctx.accounts.token_program.to_account_info(),
Transfer {
from: vault_token_account,
to: user_token_account,
authority: vault.to_account_info(),
},
signer_seeds,
),
amount,
)?;- Show withdrawal with PDA signer
- Explain safe token transfers
- Authority System:
- Show VaultAuthority structure
- Explain authorized programs for lock/unlock
- Cross-program invocation support
Terminal Setup:
- Split screen: Terminal (left) + Browser (right)
Demo Flow:
- Start Services (show commands):
# Terminal 1: Local validator
solana-test-validator
# Terminal 2: Backend service
cd backend && cargo run
# Terminal 3: Demo script
./demo/demo_script.sh- Run Demo Script:

- Initialize vault
- Deposit 1000 USDT
- Check balance
- Withdraw 200 USDT
- View transaction history
- Show TVL and system stats
- Show Database:
psql -d collateral_vault -c "SELECT * FROM vaults LIMIT 5;"
psql -d collateral_vault -c "SELECT * FROM transactions ORDER BY timestamp DESC LIMIT 10;"- WebSocket Demo:
- Open browser console
- Connect to ws://localhost:8081/ws
- Show real-time balance updates
- Show TVL updates
