Capital Swarm

AI Platforms / Agents

Capital Swarm is an autonomous capital allocation cockpit on Solana. A wallet-owning AI agent hires specialist agents, pays them with devnet SOL, collects structured reports, checks risk policy, gets a Jupiter quote, and decides whether to simulate a trade or skip. It shows real agent-to-agent payments, persistent workflow state, replayable events, optional LLM reasoning, and safe simulated PnL.

CareChain

Real World Assets (RWA)

CareChain is a Real World Asset (RWA) protocol built on Solana that transforms stalled or inefficient commercial properties into investable elderly care facilities, tokenizing bed usage rights and revenue shares through NFTs. The protocol introduces a priority queue mechanism: users holding BedRight NFTs can check in directly, while regular applicants must wait in line. Holding $CARE tokens allows users to bypass the queue—creating genuine, essential use cases for the token.

CARECHAIN

Healthcare Tech

CareChain is a decentralized health record platform built on Solana, designed to unify patient data across hospitals and clinics in Indonesia. By leveraging blockchain, CareChain ensures secure, tamper-proof, and interoperable medical records that follow patients wherever they go. CareChain provides hospitals, doctors, and patients with a seamless way to access and share trusted health information in real time.

CareStake

Healthcare Tech

Crypto Healthcare is a decentralized healthcare protocol that aligns incentives between patients and doctors using blockchain. Both parties stake $HEALTH tokens into smart contracts, and rewards depend on real patient outcomes.

Solana program (Anchor) plus Next.js web app, live on devnet at casi.gg, Apache-2.0. Built as the reference integration of casi-escrow, a reusable time-vested USDC escrow primitive.

Catalla

DeFi

Catalla is inspired by the Harvard paper “Self-Resolving Prediction Markets for Unverifiable Outcomes.” It addresses insider trading and oracle manipulation. By introducing randomized resolution and a negative cross-entropy reward for information contribution, Catalla enables both subjective and objective markets to settle trustlessly—marking a major evolution in prediction market design.

Catallaxyz

Markets & Exchanges

Catallaxyz is not an externally resolved event market. It is an attention market, an opinion market, and a lightweight SocialFi layer — a platform where users trade on subjective, open-ended questions that may have no objectively correct answer. Where event markets resolve against outside facts (“Did X happen?”), Catallaxyz markets resolve on collective user judgment, information, and consensus. The settlement price represents the weight of opinion and attention at the time of termination.

Catch my Drift

Causeway

Interoperability & Bridges

Causeway is a threshold-signature platform for multi-chain asset custody, with Solana as the control plane. Funds on Bitcoin, Ethereum, Zcash, and other chains sit in vaults whose signing keys are split across a group of independent operators. No operator can move funds alone; every transfer requires a multi-party signing ceremony, coordinated and audited through a Solana program. This eliminates the single-key risk that has cost the industry billions, while keeping every action transparent and

CCE-BROWSER

Consumer Apps

CCE — Conspiracy Connection Engine. A censorship-resistant tool that searches internet Archive, Wikipedia, and Tor to come — no Google, no tracking… AI maps hidden connections between any names, events, sciences, or organizations. Findings are saved permanently on Solana as immutable on-chain records via Phantom Wallet. No gatekeepers. No deletions. Truth on-chain forever!

Ceipt

Consumer Apps

Ceipt turns any Solana transaction into a thermal-printer receipt. Paste a signature → fetches via RPC → renders a 58mm warm-sepia receipt with JetBrains Mono, dotted dividers, and a sig-derived barcode. Different tx kinds render distinctly: Jupiter swaps show every leg, NFT mints show the mint + price, transfers get a clean line item, votes get a one-line stub, failed txs print red. Download as PNG, print to real paper, or share the URL (?sig=…). No wallet, no DB — anonymous and shareable. The

CENTRASYS

DeFi
