# Escrow & Fund Release Architecture

Sigma3 operates through a **hybrid escrow system** - combining smart-contract automation with verified milestone controls.

**Escrow Setup**

Investor contributions are locked in non-custodial smart-contract escrow. GPT360 cannot access or alter funds.

**Milestone Logic**

Fund release depends on verified proofs:

1. Signed exchange agreements
2. Listing date confirmation
3. Tokenomics and vesting locks
4. Provider readiness statements

**Fund Release**

Once verification is approved, funds are automatically released to whitelisted exchange and provider wallets.\
Any pre-funded marketing expenses are reimbursed only after milestone completion.

**Refund Logic**

If milestones are missed, **automatic full refunds** are executed on-chain. No partial releases or discretion allowed.

**Security & Transparency**

* Immutable contract parameters
* Public verification dashboard
* Third-party audited smart contracts
* GPT360 oversight nodes
