  • Loom

    Dev Tools · Local-first

    One CLI for all your coding agents. Loom weaves Claude Code, OpenCode, and bridges into a single shared thread per project — one conversation, one shared memory, one baton handoff. Local-first, published on npm as threadloom.

  • Magmos

    Payments · Circle Arc

    Payroll that arrives the moment work happens. Real-time cross-border payroll and remittances on Circle Arc — stream USDC to anyone in the world, settled per second, claimable anytime, and bridgeable home via Circle CCTP.

  • Kickpact

    Payments · Tether · WDK

    Bet on football with a wallet that's yours. A self-custodial, mobile-first World Cup prediction app where a WDK wallet holds USD₮ on-device — then you bet three ways: trustless P2P Pacts, Tinder-style on-chain Duels, or real-money Polymarket.

  • Zorr

    Gaming · Solana

    Walk. Capture. Own the map. A real-time GPS territory game on Solana — run to claim real land, collect VRF-dropped Guardian NFTs, and battle them over Bluetooth or online. Every capture settles gasless on a MagicBlock Ephemeral Rollup.

  • StellarWork

    DeFi · Stellar · Soroban

    A freelance marketplace primitive on Soroban: two smart contracts that talk to each other — a milestone escrow and an independent reputation ledger. Every settled job triggers a live cross-contract call, so a worker's track record is written on-chain by the money layer, not a trusted backend.

  • Umbra

    ZK & Privacy · Midnight

    An anonymous, verifiable notice board on Midnight. Anyone can read a notice and be sure it came from a legitimate secret-holder, yet the author's real identity stays in shadow — a Compact contract with public ledger state, a private witness, and disclose(), compiled to ZK circuits.

  • LumenFund

    DeFi · Stellar · Soroban

    An on-chain crowdfunding dApp on Stellar — multi-wallet support via Stellar Wallets Kit, a Soroban smart contract on testnet, and live funding progress driven directly by contract events.

  • Hydra Chess

    Gaming · Cardano · Hydra

    Wagered chess played inside a Cardano Hydra Head. Every move is an L2 Plutus transaction, and an Aiken escrow makes the pot unstealable and unfreezable — winner takes it, settled trustlessly back to L1.

  • Hydra Minecraft

    Gaming · Cardano · Hydra

    A fully playable Minecraft-style voxel game in the browser where every block you place or break is a real Cardano transaction on a Hydra L2 head — invisibly, with no wallet, no popups, and no delays. Built end-to-end by Claude Fable 5 from a single prompt.

  • GHOST Finance

    DeFi · Midnight

    Privacy-preserving, sealed-bid peer-to-peer lending on the Midnight Network. Lenders and borrowers post intents to an off-chain matcher; matches settle as direct wallet-to-wallet NIGHT transfers — no public order book, no exposed positions.

  • Molfi

    ZK & Privacy · Avalanche · Stellar

    Private, agent-native prediction markets. Your position stays hidden with zero-knowledge proofs, stakes are confidential via encrypted ERC, and markets resolve from Chainlink oracles — AI agents trade from a single SKILL.md.

  • null-402

    ZK & Privacy · Avalanche

    x402, but the payment is a zero-knowledge proof. An API request pays with a Groth16 proof verified on-chain — no wallet, amount, or endpoint is revealed. Agents escrow once into a shielded pool, then pay per call; only a nullifier is exposed.

  • XORR

    ZK & Privacy · Avalanche · Stellar

    Private-by-default money. Hold and transfer value with balances and amounts encrypted on-chain via eERC — every operation verified by a zk-SNARK, with a rotatable auditor that keeps it compliance-ready. Private, not anonymous.

  • Irion

    DeFi · Canton

    Buy Now, Pay Later reimagined as private consumer credit and business banking on the Canton Network. Daml smart contracts, a B2B API, a consumer wallet, merchant and neobank consoles, and an SDK — all in one monorepo.

  • Casper x402 Stream

    Agentic Payments · Casper

    A battle-ready x402 micropayments SDK for Casper — gate any HTTP route behind an on-chain micropayment with one middleware, and have clients auto-pay with one wrapped fetch. On top of it: a pay-per-second WebRTC streamer.

  • Clawback

    Agentic Payments · Casper

    Chargebacks for the machine economy. When a buyer agent pays a seller agent for a deliverable, Clawback holds the payment in escrow against a stated spec — good deliveries are released, bad ones are disputed and an AI verifier adjudicates a refund.

  • Veilex

    DeFi · HashKey

    Trade without a trace. A MEV-protected, privacy-first DEX on HashKey Chain — a pro trading terminal backed by a shielded dark-pool matcher where orders stay encrypted until matched, with live Pyth prices and real on-chain pools.

  • VeilPay

    ZK & Privacy · HashKey

    True private payments on HashKey Chain via ERC-5564 stealth addresses. Every payment lands at a fresh one-time address only the recipient can detect and spend — share a viewing key with an auditor for compliance without ever giving up spend control.

  • Fund402

    Agentic Payments · Casper

    The credit card for the machine economy. When an autonomous agent hits an HTTP 402 paywall with an empty wallet, Fund402 fronts the micropayment from an on-chain vault, settles it, and records the loan and the agent's reputation — no human in the loop.

    Dev Tools · Expo · React Native

    A premium Expo / React Native component library for fintech and Web3 — a shadcn-style, copy-paste system with a rich dark mode by default. Published on npm; you own the code once it's in your project.

  • Wallet Starter

    Dev Tools · Algorand
