Obscura

Payments & Remittance

Obscura replaces the public SPL transfer in x402 with a confidential Umbra mixer transfer. Same x402 protocol surface, same merchant integration ergonomics: one Express middleware for merchants, one fetch wrapper for agent developers. The agent's wallet is never on-chain, the amount is encrypted in a UTXO commitment, and the link between sender ETA and receiver ETA goes through Umbra's mixer commitment tree.

OBSCURA

Payments & Remittance

OBSCURA is a confidential payroll application built on Solana. Payments are made in USDC or SOL - with amounts and recipient identities encrypted using Arcium's x25519 + RescueCipher cryptographic primitives before any transaction is broadcast. The blockchain records that a payment happened, not how much or to whom. Built with @arcium-hq/client SDK, @solana/web3.js, and Phantom wallet. Real USDC transfers on devnet, real Arcium encryption, reveal-on-demand UI.

Obscura Match

DeFi

Obscura Match is a high-performance, privacy-first OTC (Over-The-Counter) crossing engine built on Solana. It leverages MagicBlock Private Ephemeral Rollups (PER) and Intel TDX Trusted Execution Environments (TEEs) to allow institutional traders to execute large block trades without pre-trade signaling, MEV, or front-running. By keeping the order book strictly confidential and executing matches within a sealed TEE environment, Obscura Match brings dark-pool levels of privacy to the Solana ecosy

ObsidianDesk — Encrypted BTC Dark Pool

DeFi

The dark pool where Bitcoin never leaves Bitcoin. ObsidianDesk is the first institutional-grade orderbook on Solana with FHE-matched encrypted orders (Encrypt) and native BTC settlement via dWallets (Ika). Price, size and side never leak — front-running is mathematically impossible. Matches trigger a selective threshold-decrypt and 2PC-MPC signing of a native BTC tx. No wBTC, no bridge, no leakage. Encrypted book + native BTC + zero custodian, in one venue.

Obsidia | Real-time intelligence for traders

Marketplace Platforms

Problem: Crypto traders lose money to three structural failures — backtests that ignore real fees and slippage, no audited way to verify someone else's "winning" strategy actually works, and a fragmented toolchain where building, backtesting, alerting, and executing each require separate apps. The result: strategies that look great in a spreadsheet bleed money in production. Solution: Obsidia is a strategy marketplace for Solana traders. A no-code DSL builder lets traders compose entry/exit con

Occult

DeFi

Institutions don't trade on public DEXs. Every swap is visible. Every large order is a target. Occult changes that. It's the first confidential AMM on Solana – swap amounts are encrypted using Token-2022 ZK proofs, batched with other orders, and settled at a uniform clearing price. MEV bots see a transaction. They never see a number. You can't sandwich what you can't read. Built entirely native to Solana. No external infrastructure. No trust assumptions. Just cryptography.

Offbank Pay

Payments & Remittance

Offbank is production-grade B2B payment infrastructure built on Solana that solves a $34B problem: cannabis operators can't get bank accounts. Today they move money through cash or predatory "high-risk" processors charging 8–12%. Settlr replaces all of that with non-custodial USDC settlement, 1% flat fee, sub-5-second finality, and a cryptographic audit trail that satisfies FinCEN, the GENIUS Act, and state regulators. The flagship integration is LeafLink, the marketplace where cannabis wholes

Onchainbet

Social / SocialFi

Project Details What is the problem you're trying to solve, and how you're going to solve it? Settling small social bets (e.g., "who wins the board game" or "who finishes the run first") often leads to forgotten debts or awkward cash exchanges. Traditional betting platforms are too complex and restricted for these minor, private social interactions. We will solve this by creating a simple web interface where friends can lock a small amount of SOL into a "social pot." Once the event is over, the
