NFTSweeps

Overview

NFTSweeps replaces off-chain raffle systems with a fully on-chain participation mechanic. Users mint ERC-1155 tokens — each one a verifiable ticket for a featured NFT project’s sweepstakes. No trust-me-bro draws. No opaque selection processes. Every entry lives on-chain.

The design challenge: make minting tickets, tracking sweepstakes, and managing entries feel immediate and clear — not like interacting with a smart contract.

The Challenge

Off-chain raffles for high-value NFT collections have a trust problem. Winners are announced, but the draw is invisible. NFTSweeps fixes that at the protocol level — but only if users actually understand what they’re participating in.

The UX had to communicate the mechanic clearly: you mint a ticket, that ticket enters you into the sweepstakes for a specific collection, the outcome is verifiable on-chain. Simple concept, but Web3 UI conventions make it easy to bury.

Simultaneously, the interface needed to handle multiple live sweepstakes, per-collection ticket counts, and real-time mint states — all without feeling cluttered.

Design Approach

Each featured collection gets its own sweepstakes card — showing the prize, mint price, tickets remaining, and time left. The hierarchy is deliberate: the NFT being won leads, the ticket mechanic supports it. Users are drawn in by the prize, then guided through the entry flow.

Minting a ticket follows a tight three-step pattern: select collection, confirm quantity, sign transaction. Confirmation state updates immediately, reflecting the on-chain ticket in the user’s portfolio. No ambiguity about whether the entry registered.

The “My Tickets” view surfaces active entries by collection, making it easy to track what you’re in for without digging through wallet history.

Key Decisions

ERC-1155 as the UX primitive. Tickets are real tokens — not database records. That distinction matters, and the UI leans into it. Tickets appear in wallet views. They’re transferable. The on-chain reality is surfaced, not hidden.

Per-collection sweepstakes, not a single pool. Each project runs its own draw. The interface reflects this clearly, preventing the confusion that comes when multiple prizes share a single participation mechanic.

Gas estimation upfront. Mint cost and gas are shown before confirmation. No surprises at signing.

Outcome

NFTSweeps shifts the trust model for NFT sweepstakes from “take our word for it” to verifiable, on-chain participation. The design makes that shift legible — users know what they minted, what they’re entered into, and when they’ll know the result.
