Cosmo-Local Credit carries forward Sarafu Network’s history, lessons and commitment-pooling work. This service transition does not mean that every historic account, asset, participant or obligation migrated. Read the history.
Cosmo-Local Credit
The Cosmo-Local Credit product family includes a progressive web app and an open protocol for creating and exchanging redeemable commitments—such as vouchers, service credits and delivery claims—through independently governed Commitment Pools.
Redeemable commitments
Issuers publish what each voucher represents and how, where and when a holder can present it for fulfillment.
Curated Pools
Pool Stewards publish admitted assets, exchange-rate methods, fees, limits, controls and any expressly scoped guarantee.
Accountable exchange
Participants inspect voucher terms, Pool rules and transaction details before exchanging assets on a public blockchain.
Empowering communities through commitment pooling
Commitment pooling enables communities to create, manage and connect their own economic systems, fostering local trade and resilience.

What brings you to Cosmo-Local Credit?
Vouchers with published terms and associated Offerings can be admitted to independently governed Commitment Pools. Accountable Pool Stewards curate those Pools so participants can exchange supported assets.

Join or create
Join an existing Commitment Pool or create your own with customizable rules and governance.
Issue and exchange

Build networks
Connect with other communities to expand exchange opportunities through compatible, independently governed Pools.
Measure impact
Inspect on-chain exchange records and combine them with separately sourced community and impact reporting.
Stewards
A Pool Steward is a trusted, accountable coordinator who manages and maintains a Pool.
Pool Stewards curate which vouchers and issuers are admitted, set reasonable limits, help participants onboard and present vouchers for fulfillment, reward supporters, and connect with other Pools sharing common assets. In return for their services, Stewards may set and collect disclosed participation or transaction fees.

Voucher Users
Swap your vouchers in Pools, present them to issuers for fulfillment, or gift them forward.

Why Cosmo-Local Credit?
Cosmo-Local Credit carries Sarafu Network’s work forward, helping communities build stronger, more resilient commons.
Community driven
Built by communities, for communities. Local governance and decision-making put power in the hands of users.
Open source and public benefit
Sarafu Network was built and stewarded by Grassroots Economics Foundation. Cosmo-Local Credit carries that transparent, open-source foundation forward.
Last-mile
Cosmo-Local Credit is a mobile-first PWA with QR flows and printable paper wallets. Sarafu’s earlier last-mile work also included NFC cards.
Secure and transparent
Public blockchain records make addresses, assets, amounts, timestamps and contract events inspectable. Published voucher terms, Pool rules and separate reports provide evidence about responsibilities and off-chain activity.
