One canonical identity
Username, display name, biography, avatar and banner — maintained once and reused by every platform you connect.
Artist identity infrastructure
One artist identity.
Every platform you use.
SolPersona is the canonical home for your profile, your verified wallets across Ethereum, Solana and Tezos, your links and your selected work — so you never rebuild your identity on another marketplace again.
On SolPersona now
Work from artists here
Cryptographically verified wallets
Prove ownership of Ethereum, Base, Polygon, Solana and Tezos addresses with a signature. No transaction, no approval, no gas.
Cross-chain, one artist
Many addresses across many chains resolve to a single artist. Applications ask SolPersona who you are, not the other way round.
Links that stay current
X, Instagram, Bluesky, Farcaster, Telegram, Discord and anything else — updated in one place, everywhere at once.
Selected artwork
Feature the work you want seen. Reference on-chain pieces without duplicating the media, or upload directly.
You hold the permissions
Applications connect through OAuth 2.1 with granular scopes. Review and revoke access at any time.
Built for platforms, too
SolPersona speaks OAuth 2.1 and OpenID Connect with PKCE. Add “Sign in with SolPersona” to your marketplace or gallery, read the artist’s profile with their consent, and let them add work to their SolPersona profile from inside your product.
