Knob

Problem Statement

Knob turns DeFi into a game you actually want to play. We aggregate Ethereum swaps, pools, and bridges into one spotless UI, then match you to opportunities tailored to your style. Compete with daily and weekly challenges, climb leaderboards, and earn surprise airdrops as you level up — all built into the product so discovery and rewards feel effortless. Our edge is security-conscious gamification: achievements are issued as Soulbound Tokens (SBTs), letting you showcase progress or share a public profile without exposing your wallet history. Think of knob as your savvy, privacy-first assistant that makes smart investing fun, competitive, and safe.It is an aggregator that brings together every Ethereum DEX, pool, and bridge. We organize everything into three clear tabs — Pools, Swaps, and Bridges — then sub-categorize entries by the types of users they suit. Each listing shows concise, actionable stats and a suitability indicator so you immediately know which opportunities match your risk profile and goals.On tokenomics and incentives, users earn by playing: complete daily and weekly challenges to earn points, climb leaderboards, and unlock airdrops or platform rewards. Achievement data is tokenized as Soulbound Tokens (SBTs) that include only relevant, shareable highlights — excluding sensitive wallet history — so your reputation is portable without sacrificing privacy.

Solution

Frontend — Next.js: Built the user-facing app in Next.js for a fast, SEO-friendly, componentized UI that powers the gamified experience and leaderboards.Protocol discovery & integration: Mapped and catalogued every protocol endpoint for the DEXes, pools, and bridges we list, then call those endpoints in a structured pipeline to ingest on-chain and protocol data.Aggregator layer: Normalizes heterogeneous protocol data into unified schemas so Pools, Swaps, and Bridges can be compared and displayed consistently in the UI.Recommendation engine / analyzer: Custom logic analyzes protocol and on-chain data plus a user’s wallet history or stated intent to score and recommend opportunities — the core “why this fits you” signal.User profiling & intent inference: We infer user types (e.g., cautious saver, yield hunter, leverager) from tracked choices and activity; those profiles feed personalized curation and challenge targeting.Privacy-preserving reputation (ERC-1155 SBT): Achievements and shareable highlights are minted as ERC-1155 Soulbound Tokens so users can showcase progress without exposing full wallet histories, preventing doxxing while enabling portable reputation.Decentralized storage (Filecoin): User preferences, choice history, and non-sensitive metadata are stored via Filecoin (content-addressed storage) to ensure tamper-evidence and decentralization of user data records.Incentivization & gamification layer: Daily and weekly challenges, leaderboard mechanics, and surprise airdrops are implemented as on-platform flows; completing challenges mints rewards or unlocks token incentives tied to the user’s account.Data privacy model: Only relevant achievement data is tokenized for sharing; sensitive transaction history remains private and is excluded from public achievement artifacts.Extensibility & integrations: The system is designed to onboard additional protocols by adding endpoint adapters and normalizers, making it straightforward to expand the aggregator universe.Notable / clever engineering: Selective tokenization of curated activity into ERC-1155 SBTs (balancing social reputation and wallet privacy) and the normalized aggregator schema that lets disparate DeFi endpoints be scored and compared uniformly.Why this stack helps: Tying a modern Next.js frontend, decentralized storage, protocol-level data ingestion, and privacy-first tokenization delivers a gamified, personalized, and secure Web3 investing assistant.
