# Compliance Capabilities

> Overview of Sonar's compliance features for token sales

## Identity Verification

### KYC (Know Your Customer)

Individual participants complete identity verification through Sonar's KYC flow.

### KYB (Know Your Business)

Organizational participants (companies, DAOs, funds) can complete business verification to participate on behalf of their entity.

## Accreditation

For sales requiring accredited investors (e.g., US Reg D offerings), Sonar can verify accreditation status.

### Verification Methods

| **Net worth**                | Verification using on-chain and off-chain assets with supporting documentation |
| **Income**                   | Income documentation (tax returns, pay stubs, etc.)                            |

## Geographic Restrictions

Block participation from specific jurisdictions (e.g., OFAC-sanctioned countries).

## Wallet Risk Screening

Screen participant wallets for risk indicators before allowing participation. Sonar screens for:

* Sanctioned entities
* High-risk addresses
* Illicit activity indicators

## Purchase Limits

Enforce minimum and maximum commitment amounts per entity. Limits are enforced at the entity level, so participants cannot circumvent them by using multiple wallets.
