zkSync DeFi Airdrops

Catena is a banking and governance platform built for AI agents. It gives autonomous agents a way to hold accounts, make payments, and manage yield while staying inside rules that a human operator defines. Catena has raised around $48 million in total: an $18 million seed round in 2025 and a $30 million Series A announced on May 20, 2026. a16z crypto and Acrew Capital co-led the Series A, with Breyer Capital, General Catalyst, and QED Investors participating. Earlier backers include Circle Ventures, Coinbase Ventures, and CoinFund.

Predikt is an API stack and protocol that unifies fragmented prediction markets into one access layer. Instead of bouncing between Polymarket, Kalshi, and other venues, traders and developers can route through a single interface for unified data, liquidity aggregation, and intelligent order execution across markets and chains. The platform targets builders first. Wallets, exchanges, and DeFi apps can plug into Predikt’s API to add prediction market functionality without integrating each venue separately. End users get faster execution and deeper liquidity by tapping aggregated order books rather than fragmented pools. The project is in early beta and a public waitlist is open.

RabbitHole is an on-chain rewards platform that pays users for holding crypto assets and staying active, rather than for completing one-off tasks. The platform is built around a Hold-to-Earn model: rewards go to wallets that hold qualifying assets and take part in campaigns over time. It is currently in its waitlist phase, so the Hold-to-Earn campaigns are not live yet and joining the waitlist is the only available action right now. RabbitHole has raised roughly $21.6 million across two rounds: a $3.6 million seed in 2021 and an $18 million Series A in 2022. Backers include Electric Capital, which led the seed, along with Greylock, ParaFi Capital, and Framework Ventures.

Phoenix is an on-chain perpetuals exchange on Solana, currently live in private beta. It is built by Ellipsis Labs, the same team behind the original Phoenix spot orderbook DEX. The new product brings perpetual futures trading to a similar on-chain orderbook design, with execution settled directly on Solana rather than through off-chain matching engines. Ellipsis Labs has raised $44.3M across multiple funding rounds, backed by several well-known crypto venture funds. Their earlier work on the Phoenix spot DEX informs how the perpetuals exchange handles order matching and latency on Solana.

Tangent is a DeFi protocol building $USG, an over-collateralized USD stablecoin minted through a collateralized debt position (CDP) model. The design takes cues from Curve’s crvUSD, with $USG backed by productive collateral like Curve LP tokens and Pendle PTs rather than idle assets. The protocol focuses on capital-efficient borrowing and yield generation. Users can mint $USG against productive positions, often at low or interest-free rates depending on the market, and earn yield through a savings vehicle (sUSG) or by providing liquidity. Peg stability is handled through Peg Keepers placed on top of the main Curve pools, similar to the crvUSD mechanism. Tangent integrates with Curve, Frax, and Pendle and is built on Ethereum. The protocol is in late-stage pre-launch, with the pre-deposit campaign opening before the public $USG release.

BULK is a decentralized perpetuals exchange built on Solana, designed to deliver CEX-level trading speed in a fully on-chain environment. The platform runs an ultra-low latency orderbook and a custom execution layer integrated directly with Solana validators, targeting traders who want leveraged crypto derivatives without giving up self-custody or censorship resistance. The project closed an $8 million seed round in September 2025, co-led by Robot Ventures and 6th Man Ventures. Backers include Wintermute Ventures, Mirana Ventures, and Chapter One, with Solana co-founder Anatoly Yakovenko participating as an angel investor. Wintermute’s involvement is particularly worth flagging given how much of a perp DEX’s success comes down to market-maker quality at launch. BULK is currently live on testnet, with mainnet expected, though no date has been confirmed. Active development covers margin modes, the risk engine, and deeper validator integration.

DogeOS is an application layer for Dogecoin that supports dApps, games, DeFi, and AI experiences on the network. The project is built by the team behind MyDoge, the largest Dogecoin wallet by user count, and pushes DOGE utility past basic payments into consumer apps. DogeOS raised $6.9 million in May 2025 in a round led by Polychain Capital. The project is pre-mainnet, with an active developer testnet called Chikyu that offers a faucet and contract deployment tools. The team also runs a public loyalty campaign called The Grand Heist to onboard early community members.

GIWA (Global Infrastructure for Web3 Access) is an Ethereum Layer 2 blockchain built on the OP Stack by Dunamu, the South Korean company behind Upbit cryptocurrency exchange. The network targets one-second block times and fees in the range of one Korean won, with full EVM compatibility so existing Solidity apps can be deployed without modification. Dunamu has raised $143.26M in funding and operates Upbit alongside two equity investment platforms, Stockplus and U-Stockplus. GIWA is the company’s on-chain layer for tying that exchange infrastructure to DeFi, stablecoins, real-world assets, and consumer Web3 apps. The L2 is currently live on a public testnet ahead of mainnet launch.

Pull.fun is a gacha platform for trading card collectibles — graded slabs like Pokémon cards. Users can pull, trade, or redeem both physical and digital cards through a system with published, verifiable odds. The model is more like a gaming gacha than a regular card market. In April 2026, the platform began early testing. Access is being given out through daily code drops and a public waitlist.

Ritual is building a decentralized execution layer for autonomous AI agents. Rather than running on centralized cloud infrastructure, agents built on Ritual can hold capital, execute transactions, and operate independently on-chain. The core product is Infernet, which is a node network that gives smart contracts access to off-chain AI models and compute. The project raised $25M in a Series A led by Archetype, with Polychain Capital, Accel, Robot Ventures, dao5, and angels including Balaji Srinivasan among the backers. Ritual launched its testnet in April 2026. No mainnet date has been confirmed.

Hit One is a perpetual futures trading platform built on MegaETH. It offers up to 1000x leverage on crypto markets, built around fast execution via off-chain order aggregation. The pitch is unsubtle: extreme leverage, arcade-style UX, aimed at traders who want speed and risk in one place. Hit One opened to the public around April 23, 2026, after dropping its waitlist.

SimpleChain is a Layer 1 blockchain built for real-world asset (RWA) tokenization at institutional scale. Unlike general-purpose chains, it bakes compliance and data infrastructure into the protocol itself, so industries can tokenize assets without bolting on third-party compliance tools afterward. The core stack includes Compliance-as-a-Service (CaaS), a Trusted Data Service (TDS) for granular on-chain asset data, and a DataIPO protocol for asset issuance. SimpleChain raised a $15 million seed round in April 2026, backed by family offices and institutional investors. The testnet launched around April 10–11, 2026, with mainnet still ahead.

Unicity Labs is an AI infrastructure company that is working on the Unicity Protocol, which is a peer-to-peer execution layer for AI agents that can work on their own. There is no shared global ledger, which is different from regular blockchains. Agents can do business with each other at machine speed, and the amount of work that can be done increases with the number of agents instead of being limited by a consensus mechanism. In February 2026, the project got $3 million in seed money, with Blockchange Ventures leading the way and Outlier Ventures and Tawasal also participating.

Melt Finance is the native spot layer on Hyperliquid, built to bring real-world assets — tokenized stocks, commodities, equities, and L1 tokens — into Hyperliquid’s ecosystem as live spot markets. Traders get 24/7 permissionless, self-custodial access to high-demand global assets on a live orderbook, with no expiration dates or funding rates. The platform runs on HyperCore’s unified liquidity infrastructure, meaning spot and perpetual markets share the same orderbook. Melt’s focus is assets that sit outside typical crypto exchanges — tokenized equities, commodity-backed tokens — routed into Hyperliquid’s trading environment.

Tings is a perpetual futures DEX that uses Hyperliquid’s HIP-3 protocol to make markets for assets that have never had them before. Prices of GPUs, unemployment rates, weather indexes, US debt levels, collectibles like $CHARIZARD or $ROLEX—things that people keep an eye on but can’t trade. Tings makes those underlying assets tradable perp contracts on-chain. Since February 2026, the platform has been in testnet. There are already live markets and a points program, but no information about public funding has been made public. If you’re farming Hyperliquid airdrops, Tings is a bet that makes sense to keep an eye on.

Purinta is a memecoin money market that lets people get liquidity out of their meme coin holdings without having to sell them. The protocol lets people use meme coins as collateral to borrow or mint USDC. In simple terms, “Deposit your memes, print USDC.” It is built on Morpho and uses Api3DAO for decentralized price feeds, which gives it a modular, permissionless base. The main use case is for memecoin holders who have a constant problem: getting liquidity without losing exposure. Instead of selling when prices are unstable, users can put up their assets as collateral and borrow against them.

STRATO is a DeFi protocol built around hard assets: on-chain gold, silver, ETH, and BTC. Users mint USDST, STRATO’s native stablecoin, by depositing these assets as collateral through a CDP (Collateralized Debt Position). STRATO calls its unique model HardFi: hard assets, powered by DeFi speed and liquidity. Every metal tokenized on STRATO is vaulted 1:1 in New York City and redeemable in person. This is physical backing you won’t find on Aave, Compound, or any standard DeFi lending market. STRATO’s founders were the first to tokenize RWAs on Ethereum and are bringing more tokenized assets to STRATO every month. The protocol charges a CDP stability fee of approximately 2-3% annually, compared to 5-15% on most competing platforms. That gap is an opportunity: borrow cheap, deploy into yield-bearing positions, keep the spread. STRATO’s vision is to make the most trusted assets in the world also some of the most productive.”

Mybucks.online is a disposable, seedless cryptocurrency wallet with 1-Click Gifting. The app allows you to quickly create a temporary wallet without downloading apps, registering, or using seed phrases. For gifting or airdropping, just deposit cryptocurrency and transfer complete ownership via a special URL known as a “Transfer Link” in the app. This implies that the wallet itself, not just the coins, can be sent. You can send money without requesting the wallet address of the recipient. It provides easy onboarding and a zero-footprint experience, functioning as a digital envelope or cash. The wallet does not use storage or third-party APIs for key management; it operates solely on the browser side. The PIN and passphrase are the main login credentials on Mybucks.online. An industry-standard, one-way hash function that has been battle-tested on Hackenproof is used to transform these into a private key and wallet address.

GenLayer is a blockchain protocol that uses AI to create a trust layer for self-driving commerce, governance, and resolving disputes. Intelligent Contracts are its main new feature. These are smart contracts that can understand natural language, deal with unstructured data, and get live web inputs to give enforceable on-chain results without the need for courts or middlemen. In August 2024, the project got $7.5 million in a Seed round led by North Island Ventures. Other investors included Arrington Capital, MH Ventures, ZK Ventures, and BlockBuilders. GenLayer is currently in the testnet phase, with both the Asimov and Bradbury testnets running and work on the mainnet continuing.

Picks is an on-chain sports prediction skill game where players choose athletes, guess how well they will do in real life, and compete on leaderboards for prizes of up to 30 times their bet. The main idea is simple: the more you know about sports, the better your results will be. Picks is different from regular sports betting because it is set up as a skill-based competition. The more a player knows, the higher they will be on the leaderboard, the more benefits they will get, and the more exclusive access they will have. The platform has a verifiable, permissionless base because predictions and results are settled onchain. The project is currently in pre-launch, and the waitlist for the pre-season is open.

The Qubic blockchain is the foundation of the high-yield project Garth ($GARTH). The story revolves around an upcoming AI takeover: on April 14, 2027, “Aigarth,” an AI system, assumes control of the project. In the interim, Garth runs an aggressive dual-engine earning system intended to serve as a source of recurring Web3 revenue. The Garth Shilling Machine, an optional social mining tool that rewards X (Twitter) activity with instant $QUBIC payouts, and the Mercy List Airdrop, a competitive weekly token distribution for devoted holders, are the project’s two main mechanisms. Future game players, NFT holders, and Zealy task finishers also accrue points for the Grand Termination Party in April 2027. Qubic is a zero-fee Layer 1 blockchain. The foundation of Garth’s tokenomics is exponential decay; each epoch, the minimum buy-in needed to qualify drops while the reward pool stays sizable in relation to participants.
