# Identity Requirements

> Reference for whitehat identity verification levels

## Identity Enum

```solidity theme={null}
enum IdentityRequirements {
    Anonymous,     // 0
    Pseudonymous,  // 1
    Named          // 2
}
```

## Levels

### Anonymous (0)

No identity verification required.

| Aspect             | Detail                |
| ------------------ | --------------------- |
| Verification       | None                  |
| Privacy            | Full                  |
| Typical Bounty Cap | \$100K - \$1M         |
| Best For           | Maximum participation |

### Pseudonymous (1)

Consistent pseudonym required.

| Aspect             | Detail                             |
| ------------------ | ---------------------------------- |
| Verification       | Provide consistent username/handle |
| Privacy            | Real identity protected            |
| Typical Bounty Cap | \$500K - \$5M                      |
| Best For           | Building reputation while private  |

**How to comply:**

* Choose a consistent pseudonym
* Use same name in all protocol communications
* Optionally link to reputation (GitHub, Twitter)

### Named (2)

Legal name verification required.

| Aspect             | Detail                                     |
| ------------------ | ------------------------------------------ |
| Verification       | Legal name confirmed via specified process |
| Privacy            | Identity disclosed to protocol             |
| Typical Bounty Cap | \$1M - \$10M+                              |
| Best For           | High-value bounties, regulated protocols   |

**How to comply:**

* Check `diligenceRequirements` field
* Complete specified KYC process
* May involve ID verification, video call, legal agreement

## Checking Requirements

```solidity theme={null}
BountyTerms memory terms = agreement.getBountyTerms();

if (terms.identity == IdentityRequirements.Anonymous) {
    // No verification needed
}

if (terms.identity == IdentityRequirements.Pseudonymous) {
    // Provide consistent pseudonym
}

if (terms.identity == IdentityRequirements.Named) {
    // Check diligenceRequirements
    string memory requirements = terms.diligenceRequirements;
    // Complete specified process
}
```

## Filtering by Comfort Level

```solidity theme={null}
// Only attack contracts matching your privacy preference
if (uint8(terms.identity) <= maxIdentityLevel) {
    // Acceptable identity requirement
}
```

## Strictness During Commitment

Identity requirements cannot become stricter during the commitment window:

```
Anonymous < Pseudonymous < Named
```

A change from `Anonymous` to `Pseudonymous` during commitment would revert.
