# General Q & A
On which centralized exchanges (CEXs) can projects expect listings when working with Sigma3 Launchpad, even without pre-arranged agreements?
Sigma3 facilitates listings exclusively on **Tier 1 and Tier 2 exchanges**, ensuring institutional-grade exposure and liquidity.\
\
Projects can expect listings **no lower than Bitget, MEXC, or Gate.io**, with additional high-tier exchange options available through Sigma3’s verified partner network.
Can participants from all countries complete KYC, and will the service be available globally (including the U.S. and Canada)?
No. While Sigma3 aims to provide global access, **certain jurisdictions will be restricted** in accordance with regulatory compliance standards.\
\
The **final list of restricted countries** will be officially published prior to launch to ensure full transparency and adherence to international regulations.
What happens if a project has already partially paid service providers outside the Sigma3 platform?
It depends on the type of service:
* For **marketing services**, Sigma3 will coordinate with its verified marketing partners to **fill any gaps** and ensure launch success.
* For **market-making services**, if previous arrangements are deemed **unreliable**, Sigma3 may **decline collaboration** with the project.
The platform ensures that all services funded via Sigma3 remain **transparent, accountable, and performance-driven**.
How does Sigma3 Launchpad differ from regular launchpads?
It ties fundraising to measurable milestones rather than just public sales, with full control over meeting listing conditions.
Who can invest through Sigma3?
Investors and $G360 stakers participating in strategic, private, or partnership rounds.
