Stellar rail
GNB is issued on mainnet for fast settlement, extremely low fees, and native asset issuance.
Important notice
GNB Coin is an independent project in development. It is not a licensed or regulated financial, banking, or payment service. The available demonstrations are for testing and technological exploration; no movement of real funds is performed. Public service payments and the integrations with BUBANK and FBG CPaaS are planned/in development and not yet operational. GNB Coin intends to operate initially under the structure of a licensed banking partner while seeking its own authorization. Nothing on this page constitutes financial advice or an investment offer.
The first cryptocurrency of Guinea-Bissau, built on Stellar
GNB Coin: a Stellar rail for financial inclusion in Guinea-Bissau.
GNB Coin is a real, verifiable token on Stellar mainnet. The vision is to connect digital payments, USSD access, and real-world assets for people without bank accounts, including basic-phone users, in Creole and Portuguese.

Roadmap
Real status, no overstatement.
The project separates what is already verifiable on Stellar, what is built as a demonstration, what is in testing, and what still depends on regulation and partnerships.

About
Financial inclusion infrastructure, not a speculative token.
GNB Coin is positioned as digital public-good infrastructure for Guinea-Bissau and WAEMU: a payment rail on Stellar designed for a population that is still largely unbanked.
The ecosystem combines GNB Coin, BUBANK, and FBG CPaaS. The token provides the Stellar rail; BUBANK represents the consumer experience; FBG CPaaS represents the USSD layer that can reach basic phones.
BUBANK intends to operate first under the structure of a licensed banking partner through a BaaS model while seeking its own authorization. Until then, demonstrations are technical and do not move real funds.
The GNB token has been issued and is verifiable on Stellar mainnet.
