Overview
Akyba is a community-savings tool that lets a group of friends, family, or neighbors pool money each cycle and take turns receiving the pot. These rotating savings circles — called tontines or ROSCAs — are how millions of people in Africa, Asia, and migrant communities save together when banks aren't an option. Akyba moves the bookkeeping into software, so no single organizer holds the cash or decides the payout order.
The protocol is built on Cardano by Oxalio Labs, a small open-source team developing it through Project Catalyst, Cardano's community-funded grants program. Two flavours of group are planned: a simple rotating circle (ROSCA), where the pot moves member to member, and a longer-running savings-and-loan group (ASCA), where the pooled fund can also issue loans the group votes on1.
Key Features
- Group savings without an organizer. Members agree on the contribution size and how often to pay in. The smart contract collects, holds, and pays out the pot in turn — no treasurer, no spreadsheet, no one walking around with cash2.
- Group-voted loans (ASCA mode). In the savings-and-loan version, members can request a loan from the pooled fund. The group votes on-chain to approve, and repayment terms are enforced by the contract instead of by a notebook1.
- Verifiable payout order. When the next-in-line position needs to be picked, the protocol uses on-chain randomness so the order is auditable by anyone, not chosen by whoever runs the group3.
- Testnet prototype, open-source code. The current build is published under the Apache 2.0 licence, and the smart contracts are written in Aiken, Cardano's purpose-built smart-contract language4.
- Rooted in informal community finance. The team frames the project as RealFi — real-world financial use cases — and is targeting groups that already use offline tontines across West Africa and similar regions4.
What to Expect
Visiting aikenakyba.web.app shows a Firebase-hosted prototype, not a finished product. Before any of the savings-circle features load, the page asks for a personal Blockfrost API key — Blockfrost is a service that lets apps read and write to Cardano. Most casual visitors won't have one, and the rest of the experience is gated behind it.
The app runs on Cardano's preview test network, so any deposits or payouts use test ADA, not real funds. There is no mainnet launch, no published security audit, and no public app metrics. People interested in following progress can check the Akyba-Protocol GitHub organization3, which holds the protocol documents and an early whitepaper PDF, or follow the team on X and Discord. The team has also stated publicly that they intend to keep building the protocol regardless of the Catalyst funding outcome2.
For a non-technical reader, the easiest way to think about Akyba is: imagine a group savings pot run by code instead of a person, where the rules everyone agreed to are the rules the software actually follows. That idea is interesting — but it is demonstrated on a testnet, by a small team, without an external audit, and only fully visible to people who can supply their own developer credentials.
