Rotating savings,
on-chain.

The tontine is the oldest savings vehicle humans ever built — a circle of members pool together, and every cycle one member takes the pot. BitTontine brings that simple contract on-chain: transparent membership, automated rotation, trust-minimised settlement. Built on Solana. Savings that don't require a bank.

Tontine — named after Lorenzo de Tonti, the 17th-century banker who formalised the rotating-savings contract. BitTontine keeps the idea, drops the middleman. Circles settle on solana; state is replicable across the Aether household stack; no custodian holds your pool.
