A Base vanity address is an EVM-compatible blockchain address containing a desired character pattern.
This guide explains Base vanity addresses, EVM vanity addresses and vanity address generation.
A vanity address is a blockchain address selected because part of its public address matches a desired pattern.
For example, a user may search for an address beginning with a specific sequence.
A vanity address does not provide additional blockchain functionality. It is primarily an address customization technique.
A Base vanity address generator repeatedly creates candidate EVM wallet accounts and checks whether the resulting public address matches a requested pattern.

Base wallet addresses follow the EVM address model.
A vanity generator can search for patterns such as:
123
888
abc
000
The actual pattern depends on the user's requirements.
The computational difficulty generally increases as the desired pattern becomes longer or more specific.
For example:
abc
abc1
abc12
abc123
Longer patterns may require significantly more candidate addresses to be generated.
A custom address can be useful for:
- Branding
- Development
- Demonstration
- Community projects
- Address recognition
A vanity pattern should never be considered a security feature.
For security-sensitive applications, vanity address generation should be performed locally.
The private key generated for a matching address must remain private.
Never send generated private keys to a remote server.
Avoid services that:
- Ask for an existing seed phrase
- Ask for an existing private key
- Require wallet credentials
- Upload generated private keys
- Do not clearly explain how keys are generated
Only use a vanity address when you can securely control the associated private key.
