What Is a Bounty Hunter?

A bounty hunter is an individual or team that earns rewards by completing specific tasks.

In the crypto space, a bounty hunter refers to someone who fulfills public tasks set by project teams and receives rewards such as tokens, stablecoins, or NFTs according to predefined rules. These tasks can range from technical activities like bug discovery and security testing, to operational objectives such as user acquisition, content creation, translation, and product feedback. Tasks are typically published, reviewed, and settled through dedicated platforms.

Why Should You Know About Bounty Hunters?

Bounty hunting provides a low-barrier way to engage with Web3 and earn direct rewards.

For participants, bounties offer a route to accumulate crypto assets in exchange for time and skills, without the need for upfront capital investment. This allows individuals to gain experience and build up their asset base. For project teams, bounty programs outsource tasks like bug finding, user acquisition, promotion, and feedback to the community, boosting efficiency in testing and growth. On an industry level, bounty systems help quickly identify high-risk issues and reduce potential losses while gradually converting newcomers into engaged users.

How Do Bounty Hunters Work?

The process can be broken down into: “Publish — Claim — Submit — Review — Settle”.

  1. Publish and Claim: Project teams publish tasks on platforms, specifying objectives, acceptance criteria, and reward ranges. Participants review requirements and either claim tasks or submit initial drafts directly.

  2. Submission and Communication: Participants submit materials per the required format—such as bug reproduction steps, impact assessments, content links, or data screenshots—and communicate with task managers to provide supplementary evidence as needed.

  3. Review and Grading: The platform or project team evaluates submissions based on severity and quality. Technical tasks are often graded as “Critical/High/Medium/Low”, while operational tasks are assessed on completion rate, authenticity, and effectiveness.

  4. Settlement and Appeals: Rewards are distributed via on-chain transfers or platform accounts. If disputes arise, participants can provide further analysis or request a review during an appeals period.

Risk management is also essential. Accounts typically require basic security measures and identity verification (KYC). Technical testing must remain within authorized scopes to avoid legal or terms-of-service violations.

What Are Common Types of Bounty Hunters in Crypto?

Bounty programs generally fall into two main categories: technical security bounties and growth/operational bounties.

Technical Security Bounties: Platforms like Immunefi and HackerOne are popular for these. For example, cross-chain bridges or derivatives protocols may offer substantial rewards for reporting reproducible critical vulnerabilities along with remediation suggestions—prizes are scaled based on potential impact to user funds.

Growth & Operational Bounties: Platforms like Zealy and Galxe are widely used. Projects set up multi-step tasks such as following social media channels, completing quizzes, testing on testnets, writing reviews, or submitting translations. Participants earn points, NFT badges, or small token rewards upon completion; accumulated points often contribute to future airdrop eligibility.

On Exchanges: Activities are often more integrated. For instance, Gate offers tasks like new token check-ins, learning quizzes, trading volume challenges, and surveys—with rewards including platform points, tokens, or vouchers. Security-related bug submissions go through dedicated “security response/bug bounty” channels with rewards determined by severity as outlined in official announcements.

Development & Product Testing: Projects may invite users to test features on testnets or early versions, report bugs and usability issues, and receive bounties per report or bundled packages.

How Can You Become a Bounty Hunter?

Start with small goals to build your reputation and portfolio step by step.

  1. Choose Your Niche: Focus on your strengths—technical bounties may involve smart contract security, front-end/back-end testing, key management; operational bounties could include content writing in various languages, video editing, translation, data analysis, or growth marketing.

  2. Set Up Tools & Accounts: Prepare multi-chain wallets and register on key platforms (Immunefi, Zealy, Galxe, etc.). Enable two-factor authentication; separate daily-use wallets from task wallets; keep records of wallet addresses and task IDs.

  3. Learn Rules & Review Cases: Study platform submission formats, evidence requirements, and prohibited behaviors. For technical bounties, review past bug reports and audit documentation; for operational bounties, collect examples of high-quality content and data presentation templates.

  4. Start Small & Scale Up: Begin with low-risk, low-reward tasks to practice submission workflows and communication styles; gradually take on higher-reward opportunities as your skills improve.

  5. Deliver Professionally & Archive Work: Technical submissions should include impact scope, reproduction steps, PoC (proof of concept), and remediation advice; operational submissions should include raw files, links, screenshots, and verifiable data. Organize completed work into a portfolio for future applications and negotiations.

  6. Stay Safe & Compliant: Only accept tasks from official sources or reputable platforms; be cautious when connecting wallets or granting permissions; beware of tasks requiring upfront payment or unsolicited group invitations. For KYC or tax-related matters, follow regulations applicable in your jurisdiction.

High-value security bounties are concentrating on critical infrastructure.

In the past year (2025), high-risk sectors like cross-chain bridges, stablecoins, and derivatives have seen top public bounties rise to the million-dollar range. Leading projects maintain long-term bounty pools ranging from $1 million to $10 million for vulnerabilities affecting fund security.

Growth bounties are becoming more platformized and point-based.

By Q4 2025, platforms like Zealy and Galxe have integrated tasks, points systems, and NFT badges. Many projects formalize the pathway from “completing tasks — earning points — redeeming/airdrop eligibility” in their rules. Single-task rewards commonly range from $5 to $200 or equivalent points; campaign durations typically last two to four weeks.

Stricter reviews and advanced anti-cheating measures.

Since the second half of 2025, platforms have widely adopted device fingerprinting, address behavior analytics, and random audits. More campaigns require KYC completion before claiming higher rewards to reduce bot and scripted activity.

On-chain settlements increasingly use stablecoins across multiple chains.

Over the past six months, rewards are more frequently paid in USDT/USDC stablecoins compatible with Ethereum mainnet and major Layer 2 networks. Tasks are increasingly conducted on testnets or Layer 2s to lower costs and increase participation.

How Are Bounty Hunters Different from White Hat Hackers?

There is overlap but also clear distinctions between the two.

White hat hackers are ethical security testers whose primary goal is to identify and responsibly disclose vulnerabilities—they mostly participate in bug bounty and security response programs. Bounty hunter is a broader term that includes not only white hats but also those engaged in growth marketing, content creation, translation, and product testing.

In terms of deliverables, white hats focus on technical details, reproducibility, and remediation suggestions; bounty hunters may also prioritize outreach impact, user conversion rates, and feedback on user experience. Regarding compensation structure: white hats tend to receive higher single payouts but face lower success rates; growth-related tasks offer more predictable but generally lower rewards per task. Understanding these boundaries helps you choose the path that best matches your skills and risk preferences.

  • Bounty Hunter: An individual who maintains protocols or discovers vulnerabilities by completing assigned tasks for rewards.
  • Smart Contract: Self-executing code deployed on a blockchain that enforces agreement terms without intermediaries.
  • Gas Fees: Transaction costs required for executing operations or smart contracts on blockchain networks.
  • Decentralized Governance: Protocol decision-making carried out by community voting rather than centralized authorities.
  • Token Incentives: Projects reward users with tokens for contributing to ecosystem growth and maintenance.

Commingling
Commingling refers to the practice where cryptocurrency exchanges or custodial services combine and manage different customers' digital assets in the same account or wallet, maintaining internal records of individual ownership while storing the assets in centralized wallets controlled by the institution rather than by the customers themselves on the blockchain.
Define Nonce
A nonce is a one-time-use number that ensures the uniqueness of operations and prevents replay attacks with old messages. In blockchain, an account’s nonce determines the order of transactions. In Bitcoin mining, the nonce is used to find a hash that meets the required difficulty. For login signatures, the nonce acts as a challenge value to enhance security. Nonces are fundamental across transactions, mining, and authentication processes.
Rug Pull
Fraudulent token projects, commonly referred to as rug pulls, are scams in which the project team suddenly withdraws funds or manipulates smart contracts after attracting investor capital. This often results in investors being unable to sell their tokens or facing a rapid price collapse. Typical tactics include removing liquidity, secretly retaining minting privileges, or setting excessively high transaction taxes. Rug pulls are most prevalent among newly launched tokens and community-driven projects. The ability to identify and avoid such schemes is essential for participants in the crypto space.
Decrypt
Decryption is the process of converting encrypted data back to its original readable form. In cryptocurrency and blockchain contexts, decryption is a fundamental cryptographic operation that typically requires a specific key (such as a private key) to allow authorized users to access encrypted information while maintaining system security. Decryption can be categorized into symmetric decryption and asymmetric decryption, corresponding to different encryption mechanisms.
Anonymous Definition
Anonymity refers to participating in online or on-chain activities without revealing one's real-world identity, appearing only through wallet addresses or pseudonyms. In the crypto space, anonymity is commonly observed in transactions, DeFi protocols, NFTs, privacy coins, and zero-knowledge tools, serving to minimize unnecessary tracking and profiling. Because all records on public blockchains are transparent, most real-world anonymity is actually pseudonymity—users isolate their identities by creating new addresses and separating personal information. However, if these addresses are ever linked to a verified account or identifiable data, the level of anonymity is significantly reduced. Therefore, it's essential to use anonymity tools responsibly within the boundaries of regulatory compliance.
