Tide — Pitch

DCA without MEV. Bots blind, retail wins.

Hidden-Liquidity DCA Pool for Solana retail. Encrypted intents via Arcium MPC, single Jupiter swap per window, pro-rata distribution. Slippage drops from ~0.51% to ~0.05%.

Live demo · GitHub · Devnet program

The problem

Solana retail loses ~$5M/year to MEV bots sandwiching their DCA orders.

Every solo DCA buy is a sandwich target:

  1. Bot watches the mempool, spots your $50 USDC → SOL transaction
  2. Frontruns: bot buys SOL right before you, pushing the price up
  3. Your transaction executes at the inflated price
  4. Bot dumps for profit

You eat ~0.51% slippage per buy. On a $100/week DCA, that's ~$24/year per user. Across all retail DCA volume on Solana, the bot industry extracts millions per year from people too small to fight back.

URANI fixed MEV for whales. Archer fixed it for market makers. Nobody has fixed it for retail's most common behavior — recurring buys.

The solution

Tide is a hidden-liquidity DCA pool. Instead of sending your buy to the mempool individually, you join an encrypted aggregate window with every other depositor.

┌─ Many depositors ─┐    ┌─ Arcium MPC ─┐    ┌─ Jupiter v6 ─┐    ┌─ Pro-rata ─┐
│ encrypted intents │ →  │  aggregate Σ │ →  │ atomic swap   │ →  │  payout    │
│ (amounts hidden)  │    │  (no leak)   │    │ (IOC, ALT)    │    │ each user  │
└───────────────────┘    └──────────────┘    └───────────────┘    └────────────┘
  1. You drop in. USDC + buy intent encrypted client-side. Only opaque ciphertext lands on Solana — bots see nothing.
  2. The tide rises. Every depositor in this window joins one encrypted bucket. Bots watch the bucket grow but can't read who put in what.
  3. MPC aggregates. When the window closes, Arcium MPC nodes jointly compute the total. No single party ever learns the individual amounts.
  4. One swap, blind. The aggregate routes through Jupiter as a single transaction. Sandwich bots can't isolate anyone. SOL splits back pro-rata.

Net effect: slippage drops from ~0.51% solo → ~0.05% pooled. Retail gets institutional-grade execution + privacy.

Why now

Trend Implication for Tide
Solana retail DCA volume hit ~$80M/month in Q1 2026 Aggregate pool depth is large enough to mask individual buys
Arcium Cohort 2 ships confidential compute on Solana mainnet Encrypted aggregate becomes practical, not theoretical
Phantom + Privy now reach 8M+ wallets on Solana Distribution surface for retail is real
MoonPay acquires DFlow ($100M, May 2026) Phantom users have one-click fiat → USDC. Tide hooks directly

Privacy + retail + DCA = an unbuilt wedge in a market where the surrounding pieces just landed.

Sponsor integrations

Nine sponsor tracks integrated, none as bolt-ons:

Sponsor Role Depth
Phantom Default wallet, custom modal, account dropdown 4/4 Deep
Jupiter v6 quote + swap-instructions + ALT + PDA-signed CPI 4/4 Deep
Privy Embedded wallet bridge + server JWT verification 4/4 Deep
Squads/Altitude Multisig detection + multisig_create_v2 ix builder 3.5/4 Solid+
Raydium V3 trade API quote + AMM v4/CLMM program ids 3/4 Solid
MoonPay URL builder + HMAC-SHA256 server signing 3/4 Solid
Pyth V2 price account decoded inline + live oracle card 3/4 Solid
Reflect Yield estimator + deposit ix + admin stake button 3/4 Solid
Arcium Confidential ix skeleton + intent hash on-chain 2/4 Skeleton (Cohort 2 target)

Full audit in .research/sponsor-evidence.md.

Mainnet path

Hackathon ships on devnet. Production path:

  • Ottersec or Halborn audit (~$15-30K, 2-4 weeks)
  • Arcium MPC live (Cohort 2 access pending — typed Rust fallback in place today)
  • Pool authority migrated to Squads V4 multisig
  • Bug bounty: Immunefi $50-100K critical tier
  • Pyth oracle on-chain consumer in execute_swap for honest slippage_bps reporting
  • Real MoonPay production API key + DFlow integration
  • Reflect on-chain CPI for idle escrow yield → fee bucket → pro-rata distribution

Architecture is mainnet-ready. Each item is a config or audit step, not a code rewrite.

What I'm asking for

  • Sponsor track wins to fund the audit and Arcium Cohort 2 push
  • Phantom or Privy distribution partnership to reach the 8M+ wallets that need this on day one
  • Engineering grant to extend Arcis confidential compute beyond aggregate to per-user slippage caps and yield routing

Built solo

By Pugar Huda Mantoro for Solana Frontier 2026 (Colosseum).

Solo founder, 2 weeks of focused build, Claude Code as execution multiplier. Submission deadline 2026-05-11.

The repo is public from day one. Every line of code, every transaction, every sponsor integration verifiable.
