Problem Statement

dPulse — Decentralized, Incentivized Polls & SurveysdPulseis a Web3-native toolkit that lets any project, DAO, or appcreate polls and multi-question surveys,target the right respondents, andautomatically reward participationon-chain. It solves three persistent problems in community research: (1) low-quality, sybil-driven responses, (2) painful/manual reward distribution, and (3) poor interoperability with the rest of a project’s on-chain stack.What it isA modular, EVM-compatible protocol and dApp that:Creates “Projects”(containers) that hold bothsingle-question pollsandmulti-question surveys.Gates participationwith pluggable identity/reputation signals (e.g., token/NFT/POAP ownership, allowlists, EAS/Gitcoin-style attestations, off-chain credential proofs).Incentivizes responseswith native ETH or any ERC-20, using built-inescrow + payoutflows.Automates reward swaps(optional): respondents canaccumulate small rewardsandwithdraw once a minimum threshold (e.g., $10) is reached, receivingthe token of their choicevia an aggregator/bridge (e.g., SideShift/DEX route), reducing dust payouts and gas waste.Prevents fraud & double votingwith flexible modes: open voting,allowlisted voting,one-wallet/one-vote, and ananonymous mode(commit-reveal now; ZK/Semaphore-style proofs on the roadmap).Streams results in real timeand exposesclean APIs/ABIsfor dashboards, bots, and integrations.Why it mattersHigher-quality insights:You choose who can respond and how often, aligning incentives with proof of personhood, skin-in-the-game, or community tenure.Operational simplicity:No more spreadsheets or manual airdrops—rewards and settlement are on autopilot.Composable by default:Everything is on-chain or hash-anchored, so downstream tools (analytics, governance, CRM, Telegram bots) can subscribe and act.How it works (flow)Creator sets up a Project→ defines poll/survey, target audience, reward pool (ETH/ERC-20), eligibility rules, response window, and min-withdrawal threshold (optional).Respondent connects a wallet→ passes eligibility checks (tokens, attestations, allowlist).Respondent submits answers→ on-chain event and/or off-chain payload (IPFS/Arweave) withon-chain hash; gas-optimized pathways are available.Protocol validates entry→ enforces uniqueness (per poll rules) and creditsescrowed reward balanceto the respondent.Withdrawal→ when balance ≥ threshold, respondentwithdraws in their preferred assetvia auto-swap; otherwise, direct token withdrawal is always available.Results→ creator reads live tallies, filtered cohorts, and exports.Key featuresProjects, Polls & Surveys:one space to manage all research.Flexible question types:single/multiple choice, Likert scale, free-text (hashed), numeric.Targeting & gating:ERC-20 balances, NFT/POAP holds, allowlists, attestations.Incentives engine:per-response fixed reward, tiered rewards, or capped pools.Escrow + Auto-Swap (optional):batch small earnings; withdraw as selected token.Anti-sybil modes:per-wallet cap, per-identity cap, commit-reveal, anon mode roadmap.Developer-friendly:ABI, REST/Graph endpoints, webhooks, and event indexes.Auditable & exportable:all critical state verifiable on-chain; results export.Technical architecture (MVP)Smart contracts (Solidity, EVM):ProjectsRegistry(UUPS-upgradeable): create/manage Projects.PollsAndSurveys(modular): store metadata refs (IPFS/Arweave), rules, and state.RewardsEscrow(ERC-20 & ETH): credit balances; enforce min-withdraw; payout.Access/Gating module:pluggable checks (token/NFT, allowlist, attestations).Event logfor indexing and analytics.Data model:On-chain:poll/survey config, rules, merkle roots/hashes, tallies, reward ledger.Off-chain (content):question text, long answers, attachments → IPFS/Arweave, anchoringcontent hashon chain.Indexing & APIs:a lightweight indexer + API/Graph layer for fast queries and dashboards.Wallet UX:EOA support;ERC-4337 account abstraction(roadmap) for gas-sponsored flows.What’s novelReward Auto-Swap + Threshold Withdrawals:designed for micro-rewards without dust.Research-grade gating:mix on-chain signals and attestations to target the right cohorts.Both polls and multi-question surveysunder one on-chain roof, grouped by Projects.Example use casesDAO governance temperature checkswith token-weighted or one-member-one-vote.Protocol UX research: survey users who actually used a feature/NFT.Partner marketing: pay qualified respondents in the asset they prefer.Hackathons & grants: fast community feedback with verifiable participation.Current status (hackathon scope)Core contract design (upgradeable, modular) and schema.MVP flows forcreate → respond → reward → withdraw.Minimal indexer and dashboard for live results.Optional auto-swap integration path and min-withdraw mechanics.Roadmapv0 (Hackathon):core contracts, Projects, polls/surveys, rewards escrow, basic gating, dashboard.v1:auto-swap withdrawals, richer question types, analytics API, role-based team access.v2:anonymous ZK voting mode, ERC-4337 gas sponsorship, advanced cohort targeting, integrations (Discord/Telegram bots, governance frameworks).

Solution

How it’s made — dPulse (Hackathon Version)Core Goal:Build a minimal but functionaldecentralized polls & surveys dAppwhere:Creators can set up a poll/survey with a reward pool.Respondents can answer and automatically earn small token rewards.Results are visible on-chain and in a simple dashboard.Tech StackSmart Contracts (Solidity, Hardhat)PollsContract: create polls/surveys, store metadata (IPFS link), and record responses.RewardsEscrow: hold reward tokens (ETH or ERC-20) and distribute per valid response.Simpleaccess control(poll creator vs responder).StoragePoll & survey text/questions → stored onIPFS.Onlyhash + linkstored on-chain to keep gas low.FrontendNext.js + Reactfor the web app.wagmi + RainbowKitfor wallet connections.Basic flows:Create Poll/SurveyRespond to PollView ResultsIndexingMinimalNode.js listenerthat reads contract events and pushes to frontend (optional; can also read directly from contract).Features BuiltCreate Poll/Survey— set title, questions, and reward pool (ETH/ERC-20).Respond— connect wallet, submit answer, and get credited a reward.Reward Distribution— every valid response earns a small token reward directly.Results Dashboard— tallies displayed live from contract events.Hacky/Notable BitsKept it lean:only store what’s essential on-chain (hashes, tallies, rewards) and offload content to IPFS.Escrow payout logic:simple balance ledger that transfers tokens immediately (no thresholding, no auto-swap for now).Gas-friendly design:answers encoded compactly (multiple choice → numbers, free-text → hash).✅ This stripped-down version isMVP-ready for ETHGlobal:Showson-chain polls & surveys.Demonstratesautomatic incentives.Keeps contracts small, auditable, and deployable fast.
