Cashmere

Cashmere is a multi-signature wallet built specifically for Solana-based organizations, enabling teams to jointly manage treasury assets such as SOL and SPL tokens. Its core business revolves around secure collaborative fund control: transactions require approval from multiple designated owners before execution, eliminating single-point-of-failure risks. The wallet uses Program Derived Addresses (PDAs) to manage authority, and integrates with both hardware and software Solana wallets.

Key differentiators include institutional-grade security without cold-storage dependency, a user-friendly interface for team operations, and integration with Castle Finance for yield opportunities directly within the multisig. It also offers an MEV-protected DEX aggregator for cross-chain swaps, which simulates and disables bot attack patterns to ensure optimal swap outcomes.

Market pain points addressed: traditional single-signer wallets expose shared funds to theft or misuse; multisig solutions often lack usability or Solana-native features. Cashmere solves these by combining robust approval workflows with a clean UI and native Solana asset support.

Regarding recent development (2026-02-28 to 2026-08-29): no reliable public information was found within this period. The project's social activity appears dormant (last update around April 2025). No significant negative events were identified in the past two years beyond general market volatility.
