Solana dApp Store

Publish your TWA to the Solana dApp Store.

Overview

The Solana dApp Store is a decentralized app marketplace for Solana Mobile devices (Saga, Seeker). Publishing involves creating NFTs that describe your app on-chain and submitting for review via the Publisher Portal.

Key Benefits:

• No platform fees - 0% commission on app sales
• Crypto-native - Accepts SOL payments
• NFT-based publishing - App metadata stored on-chain
• Self-service - Publish whenever you're ready

Before You Begin

Before starting the publishing process, review these important documents:

• Publisher Policy - Content guidelines and requirements
• Developer Agreement - Terms for all submissions

Prerequisites

• Release APK - Signed with a unique signing key (not your Google Play key)
• Publisher wallet - Solana wallet with ~0.2 SOL for fees and storage
• App metadata - Name, description, screenshots, icon
• Digital Asset Links - Configured for your TWA

Important

Your publisher wallet is required for all future submissions. Do not lose access to it or you will not be able to make updates to your app.

• ArDrive (Recommended) - Lower storage costs, easy setup
