# Sigma3 Launchpad

Sigma3 Launchpad is the core fundraising platform of the GPT360 ecosystem, built to close the gap between a project’s Seed round and its public Token Generation Event (TGE).\
Unlike traditional launchpads focused solely on public sales, Sigma3 introduces a **milestone-based funding model** that connects verified Web3 projects with investors and vetted execution partners -including exchanges, market makers, and marketing agencies.

Through a **smart-contract escrow system**, funds are released only when measurable listing milestones are achieved, ensuring:

* **Transparency** - every stage of fundraising is visible and verifiable on-chain.
* **Accountability** - capital cannot be redirected beyond verified scopes.
* **Security** - 100% refund coverage if listing milestones are not achieved.

Sigma3 serves as the **bridge between capital and execution**, guaranteeing that every GPT360-verified project not only raises funds but delivers a validated, on-time market launch with proven service partners.
