OmegaChain
Verify a unique digital challenge coin against its signed public record.
What These Are
OmegaChain coins are unique, non-financial digital challenge coins. They are commemorative keepsakes, not cryptocurrency, NFTs, securities, or investments.
Why I Make Them
I designed these coins as a personal way to thank people who support my work, including Ko-fi donors, and to mark that appreciation with something verifiable.
How They Verify
