Where SI lives today

Flo distributes through partners. The same SI on-chain is the asset every partner integrates against; partner UIs may relabel it for their own brand.

Partner integrations in build

No live partner is distributing SI yet. Twelve integrations are in build across exchanges, wallets, fintechs, neobanks, and asset managers. Partners are listed here only after they ship.
