The problem it solves

We enable people to mix their funds while gaining permissionless access to early-stage projects across chains, tapping into Solana capital markets.

  • No mainstream mixer is built into DeFi
  • No private way to access early-stage tokens
  • NEAR Intents-based and cross-chain launchpads are not permissionless for creating tokens (e.g., Calyz)
  • Lack of cross-chain launchpads that let you pay in any token and launch permissionlessly
  • No Zcash-based launchpad—no such thing as private capital markets
  • Private sales are not open, but open public sales are not private

Challenges we ran into

  • No message passing into NEAR Intents (why we needed to use TEE with 1-click API)
    • How we solved: we used Phala tee to generate a proof based on rest API response of set payment amount
  • No native ways to pay for APIs with crypto
    • Just opsec
  • NEAR Intents not having a testnet
    • Used mainnet with small amounts and prefilled testing amounts
  • Shielded pools support unclear on NEAR Intents
    • Coordinated with team on timeline
  • Gas issues with claiming for bridges
    • Still exploring either Layer Zero or deBridge to claim tokens on any chain in the future
  • Taking Zcash payments and bringing them to Solana to automate into liquidity pools
    • Need to build smart accounts and use Tuk Tuk for liquidity integration
  • Having a private way for redeemable addresses
    • Reinforcing needed for shielded pools
  • Time constraints around integrating partners
    • Built this whole thing in a week, continuing as a product
  • Starting late
    • Grinding
  • Paying for many tickets while keeping privacy
    • We still need to streamline this flow. Also, NEAR Intents sometimes takes a while to settle in Zcash
  • UX issues outlining anonymity sets for users
    • Clearly outlined anonymity set on front end and enforced by only allowing claims after sale completed
  • Privacy founders getting incarcerated—opsec matters without having this used against us as we go to market
    • FREE KEONNE, BILL and Roman

Time extension would help—we really wanted to build a complete product

Future Plans

We were previously building cross-chain launchpad infrastructure, but the architecture didn’t work well for users. This mixer model with bridged tokens makes the experience much simpler, and we’ll continue developing it as a product. We have a 10+ person team focused on go-to-market for a controversial launchpad that needs privacy technology as core infrastructure. Here are our plans for the next two weeks:

  • Add Layer Zero or deBridge to enable on-chain claiming
  • Build automation for providing liquidity automatically
  • Enable more advanced tokenomics and allocations
  • Streamline the ability to mass-create tickets and improve this flow
  • Improve UX and visualizations of the anonymity set
  • Make it easier for other launchpads to integrate
