Save and grow
together

Before modern banking, communities globally saved together through rotating savings associations. Known traditionally as a Sou-Sou in the Caribbean, Tanda in Latin America, Esusu in West Africa, or Partnerhand in the UK.

ROSA digitizes this age-old custom. Members contribute a fixed amount each round, and one member takes turns receiving the full pooled pot. By deploying smart accounts and optional smart contract security deposits, we completely eliminate default risk while generating real DeFi yield on idle assets.
