splitkey: Three Ways to Own a Vanity Address That the Seller Cannot Touch

Sat, 24 Oct 2026 00:00:00 +0000

Every vanity address has the same problem. It is found by brute force, so somebody knows the private key. The question is not “is the seller honest today?”. The question is “what can a copy of that key do tomorrow?”.

I made splitkey.me to answer that question in public, with one rule: every claim must be checkable on-chain, by you, without us.

Answer 1: Stellar, by rotation

A Stellar account is not the same thing as a key. It has a list of signers with weights, and thresholds. So a seller can deliver an account without delivering a key:

A Stellar address looks like this: GD4DNGO25NUOX5TCYBSNRGJ3JEYHCB2GAA2FC4AKADFQQYSKEYPLATES. It is 56 characters of base32. Nobody remembers it, and everybody checks only the first and the last four characters. Scammers know this very well.

Now look at the end of that address again: …KEYPLATES. That is a vanity address. A word in an address is easier to recognize and easier to check. It is also a nice thing to own, like a good car number plate. Hence the name: KeyPlates.
