In this article we provide a detailed analysis of the first Polygon‑based Web3 wallet launched through the partnership between Grab and Polygon. We examine how the service is being rolled out in Singapore, the use cases for NFT coupons, and the potential impact on the digital‑payment ecosystem in Southeast Asia. Read on to understand how this development could reshape everyday consumer experiences.

Grab has teamed up with Polygon to launch a Web3 wallet built on the Polygon blockchain in Singapore. The wallet allows users to collect NFT coupons and manage digital assets.
Grab is often dubbed the “Uber of Southeast Asia” and is the region’s largest ride‑hailing platform. Its multifunctional app boasts roughly 180 million registered users, with nearly 35 million monthly active users, and operates in more than 500 cities. In addition to rides, the app offers food delivery, parcel courier services, and online payments.
Grab Web3 Wallet Collaboration with Polygon
- Partners: Grab and the Monetary Authority of Singapore (MAS) jointly oversee the wallet, which is hosted on the Polygon network.
- Features: Singaporean users can select a Web3 option on the checkout screen, create a custodial wallet, and receive NFT coupons.
- Asset Types: At launch only two digital‑asset categories are supported – the SG Pitstop NFT coupon and the SG Pitstop Pack digital collectible – both of which can be redeemed for food‑service discounts and similar perks.
When a user taps the Web3 button inside the app for the first time, they are guided through a wallet‑creation flow. The wallet does not expose a private key; instead it relies on a PIN code and a questionnaire‑based account‑recovery mechanism.

Use Cases and Acquisition Methods
- Purchase channel: Acquire the SG Pitstop Pack through the FaveApp marketplace.
- Application scenarios: The NFTs can be used during the upcoming Formula 1 Singapore Grand Prix and at local partner merchants such as Treasure Seafood Restaurant in Clarke Quay, granting holders exclusive discounts.
- Asset withdrawal: Users may transfer the assets stored in the wallet to another wallet of their choice. The official guidance warns against sending unsupported digital assets to the custodial wallet, as doing so could render the assets inaccessible.
Future Development Directions
- Asset‑type expansion: Grab is evaluating the addition of more digital‑asset categories that can be stored in the wallet.
- Potential for crypto payments: Although crypto‑currency payment functionality is not available today, regulatory approval could enable crypto payments within the wallet, potentially extending payment options for the platform’s almost 200 million user base.
Pilot Partnership Between Grab and Singapore MAS
- Pilot scope: In June 2023, Grab and MAS signed a pilot agreement to explore the use of central bank digital currencies (CBDC), tokenised bank deposits, and stablecoins.
- Cross‑platform experiments: Grab is also collaborating with Amazon and Southeast Asian fintech firm Fazz to test a “Purpose‑Bound Money” retail‑payment system that leverages digital assets.
These points summarize the key aspects of the Web3 wallet that Grab and Polygon have introduced. For further updates on NFT storage and the prospect of crypto‑enabled payments, stay tuned to Bitaigen’s (BitRoot) forthcoming reports.
