RallyMint is a sales platform for Web3 token pre-orders (presales). It supports multiple chains across Solana / EVM and 8+ wallets, handling over 50,000 participating wallets in a simultaneous global launch.
Multi-chain connection, crypto payments, fraud prevention, and resilience to traffic spikes — a platform that simultaneously satisfies the 4 axes essential to token sales, from scratch in 4 months of in-house development — a new platform launch story.
The client is a Web3 startup running token and community businesses built on blockchain technology. It grows around presale (early-sale) campaigns that issue new tokens to the world and launch them together with the community.
A presale is a one-shot sales event that participants worldwide access all at once. The client needed a dedicated platform that safely accepts wallets across multiple chains, lets buyers pay in crypto without hesitation, and makes community momentum visible.
None of these were questions of technology choice — they were business requirements tied directly to participation completion rate, community growth, and sales integrity. Building anew from scratch demanded a design that made them all hold true at once.
Solana and EVM have entirely different wallet specifications, Separate flows would cause many participants to drop off before connecting.
Crypto payments have complex steps, Get the UX wrong and beginners can't complete a purchase.
A wallet alone can't guarantee identity, Get the safeguards wrong and duplicate or fraudulent entries undermine sale fairness.
At the launch moment, access surges from around the world, Get the architecture wrong and the service stalls at the peak selling moment.
Multi-wallet connection, crypto payments, participant engagement, and reliability — together with the Web3 startup, we built the 4 domains essential to token sales in-house from scratch. A front-end-complete, serverless-leaning architecture automatically scales with the spikes of a simultaneous global launch.
