Quest Protocol

Any project can deploy a quest—a smart contract defining a task and reward—without requiring approval from a central authority. This enables rapid, trustless bootstrapping of communities and marketing campaigns.

• Defines On-Chain Actions: Tasks can include token swaps, NFT mints, social follows, or custom contract interactions.
• Automated Verification: Completion is validated by the protocol's verifier contracts, eliminating manual review.

The protocol operates as a cross-chain primitive, allowing quests to be created and completed across multiple blockchain networks. This is facilitated by its architecture and integration with cross-chain messaging protocols.

• Broad Reach: Creators can target users on Ethereum, Polygon, Base, and other supported chains from a single interface.
• Unified Experience: Users interact with quests natively on their preferred chain, with rewards often distributed on the same network.

Reward distribution is governed by immutable, on-chain rules set at quest creation. This enables complex incentive structures beyond simple token transfers.

• Dynamic Rewards: Implement tiered rewards, lotteries, or time-based bonuses directly in the quest contract.
• Conditional Payouts: Release rewards based on specific on-chain conditions or user eligibility checks, ensuring fairness and preventing sybil attacks.

Task completion is not verified by a central server but by a network of verifier nodes or smart contracts that check on-chain transaction data against the quest's predefined rules.

• Trustless Proof: Users submit proof of their on-chain action (e.g., a transaction hash), which is cryptographically verified.
• Sybil Resistance: The system uses mechanisms like proof-of-humanity integrations or stake-based challenges to deter fraudulent completions.

The protocol promotes interoperability through standardized interfaces for quests and verifiers. This allows other dApps and platforms to build on top of the questing infrastructure.

• Developer SDKs: Tools and libraries let developers integrate quest creation and completion into their own applications.
• Plugin Ecosystem: Wallets and dashboards can easily display and manage quests from any creator using the standard.

Every quest completion is recorded on-chain, creating a permanent, verifiable record of user participation and contribution. This data layer is valuable for both projects and users.

• For Projects: Access granular analytics on campaign performance, user engagement, and ROI.
• For Users: Build a portable proof-of-work reputation—an on-chain resume of completed tasks and skills demonstrated.

Brands and DAOs launch quests to amplify social reach and community participation. Common tasks include:

• Social verification: Following an account, liking, or retweeting a post.
• Content creation: Submitting a meme or article related to the project.
• Referral programs: Inviting friends to complete a quest. Rewards are distributed automatically upon proof-of-completion, making campaigns scalable and fraud-resistant.

Quests function as verifiable credentials for on-chain skills. Completing a multi-step quest on an NFT marketplace (e.g., minting, listing, bidding) generates a Soulbound Token (SBT) or non-transferable NFT that serves as a portable record of proficiency. This creates a decentralized resume for web3 roles, allowing protocols to identify and reward experienced users programmatically.

Quests can orchestrate actions across multiple dApps in a single user journey. For example, a "DeFi Explorer" quest might require:

1. Bridging assets via a bridge protocol.
2. Swapping on a DEX.
3. Depositing into a lending market.
4. Using the collateral to mint a stablecoin. This demonstrates composability, educating users on the interconnected DeFi stack while driving volume to integrated partners.

DAOs use quests to increase voter turnout and educate members on proposals. A quest may require users to read a governance forum post, cast a vote on Snapshot, and delegate voting power. Completion rewards, often in governance tokens, align incentives, reduce voter apathy, and ensure the community is informed and engaged in key decisions.

The protocol can integrate with oracle networks like Chainlink to verify off-chain events. A quest could require submitting proof of attending a real-world conference via a verified POAP (Proof of Attendance Protocol) NFT or providing a geolocation signature. This bridges physical and digital actions, enabling new forms of authenticated engagement and loyalty programs.

Protocols and developer platforms create interactive tutorials as quests to guide new users through core functionalities.

• Process: A quest walks a user through minting an NFT, interacting with a smart contract, or executing a swap.
• Outcome: Users learn by doing and earn a verifiable credential (often an NFT) proving their new skill, which can be used in reputation systems.

DAOs and communities leverage quests to incentivize participation in governance, content creation, and social amplification.

• Common Tasks: Voting on a proposal, creating educational content, or sharing project updates on social media (with on-chain proof).
• Result: Aligns community incentives, increases active participation, and builds a reputational graph of engaged members.

The protocol creates a structured data layer of user engagement across Web3. Every completed quest is a verifiable, on-chain record of a user's actions and interests.

• Use Case: Projects can analyze quest completion data to understand user behavior, segment audiences, and measure campaign ROI.
• Output: Generates attribution data for growth efforts, moving beyond vanity metrics to actionable insights.

Quests are designed to be chain-agnostic, allowing projects to create campaigns that span multiple blockchain ecosystems.

• Implementation: A single quest can require actions on Ethereum, Polygon, and Arbitrum, verified via their respective blockchains.
• Benefit: Enables projects to engage users across the broader multi-chain landscape without being siloed to a single network.

Quest Protocol functions as modular infrastructure that other dApps and platforms can integrate to add quest-based mechanics.

• Integration Examples: A wallet app might embed quests for user onboarding. A game could use it for achievement tracking.
• Ecosystem Effect: Becomes a standardized primitive for programmable incentives, similar to how Uniswap is a primitive for swaps.

The core security of a quest relies on the integrity of its verification logic. This is the smart contract code that determines if a user's submitted proof is valid. Vulnerabilities here can lead to:

• False positives: Users receiving rewards for incomplete tasks.
• False negatives: Legitimate users being unfairly rejected.
• Logic exploits: Attackers manipulating inputs to bypass verification. Auditing this logic is paramount, as it directly controls the protocol's treasury outflow.

A Sybil attack occurs when a single entity creates many fake identities to complete quests and claim disproportionate rewards. The protocol must implement robust Sybil resistance mechanisms, such as:

• Proof of Personhood: Integration with services like World ID.
• On-chain reputation: Using historical wallet activity and NFT holdings.
• Staking requirements: Requiring a deposit to participate, which is slashed for malicious behavior. Without these, reward pools can be drained by automated bots, undermining the quest's purpose.

The mechanism for holding and distributing rewards (tokens, NFTs, points) must be secure. Key risks include:

• Centralized custody: If rewards are held in an upgradable contract or EOA, they are vulnerable to admin key compromise.
• Reentrancy attacks: Flaws in the payout function could allow drain attacks.
• Front-running: Users competing to submit proofs first when rewards are limited. Best practices involve using audited, non-custodial escrow contracts and implementing checks-effects-interactions patterns.

Many quests require verifying off-chain events (e.g., Twitter posts, website visits). This typically depends on oracles or indexers. Security considerations include:

• Oracle manipulation: If the data source is compromised, verification fails.
• Centralization risk: Relying on a single oracle creates a single point of failure.
• Data freshness: Using stale or incorrect data to validate proofs. Using decentralized oracle networks (like Chainlink) and multiple data attestations can mitigate these risks.

The user-facing application (dApp) is a critical attack vector. Threats include:

• Malicious quest creation: UI that tricks users into signing malicious transactions, leading to asset theft.
• Phishing: Fake websites impersonating the official quest platform.
• Wallet drainers: Injected scripts that compromise connected wallets. Users must verify contract addresses and transaction details before signing. Platforms should implement transaction simulation and clear warnings.

Many quest protocols use upgradable proxy patterns for flexibility. This introduces centralization risk:

• Admin key compromise: A single private key could upgrade the logic to a malicious contract, draining all funds.
• Rug pulls: Malicious admins can withdraw treasury funds or disable withdrawals. Mitigations include using timelocks for upgrades, multi-signature wallets for admin controls, and moving towards decentralized governance over time.

A security and membership model where access to a resource (e.g., a Discord channel, website content, or mint) is conditional on holding a specific NFT or token. This is a common outcome or reward mechanism within quest systems.

• Quest Integration: A quest may reward an NFT that gates access to future communities or events.
• Utility: Transforms quest completion badges into functional access keys.

Verifiable records of a user's achievements, affiliations, or reputations stored on a blockchain. Quest protocols issue these as Soulbound Tokens (SBTs) or non-transferable NFTs to create a persistent, composable identity graph.

• Data Type: Can include governance participation, skill completion, or event attendance.
• Ecosystem Role: Serves as the portable, verifiable output of completed quests across platforms.
