LinkAja builds Sharia wallet, wins 100k users in month

Indonesia's 220 million Muslim consumers spend $224 billion annually, but fintech startups must pass the Indonesian Ulema Council (MUI) and its 154 fatwas to reach them. LinkAja, already serving 45 million users, decided to build LinkAja Sharia Services — a parallel, Sharia-compliant version of its mobile wallet — rather than retrofit the main app.

The company appointed Widjayanto Djaenudin as Head of Sharia and submitted to a rigorous MUI process: a three-cleric supervisory board reviewed market research, product tests, and engineering monthly. Fatwa No. 116 required floating funds to sit in certified Islamic banks, all contracts to follow Sharia law, and zero riba in promotions. The board also mandated a built-in zakat (alms) feature linked to 240 MUI-approved charities and 1,000 mosques.

After a full operational audit and a $300 certification fee, LinkAja Sharia Services launched on 14 April 2020, one week before Ramadan. In its first month it recorded 100,000 user registrations. LinkAja's research showed most Indonesian users choose a Sharia-branded service simply because they trust the MUI halal logo, not because they understand mudarabah or riba details.

100,000 Sharia wallet registrations in first month; MUI certificate became primary trust signal for Muslim users

VP Ma'ruf Amin's November 2019 'Shariatization' decree made Sharia fintech a national priority, creating regulatory tailwinds.

MUI certification is legally required by Indonesia's financial regulator (OJK) for Sharia fintech, so compliance was mandatory, not optional.

LinkAja's internal research confirmed the MUI logo alone drives consumer trust and adoption among the Muslim majority.

A parallel app architecture let LinkAja keep its existing 45 million conventional users while adding a fully compliant Sharia track.

Embedding zakat payments with 240 approved charities and 1,000 mosques created a daily religious-use hook that conventional wallets lack.

In faith-driven markets, formal religious certification can be a stronger growth lever than product features alone.

LinkAja Sharia Services became a template for Indonesian fintech: the MUI certificate is now the de facto entry ticket, and competitors race to replicate the supervised-board model. The case proved that in Indonesia, religious legitimacy is a product feature that converts directly into users.
