# dutch-auction dynamic bonding curves solve the token launch pricing problem by combining descending price discovery with ascending supply curves eliminating the instantaneous arbitrage that has cost token deployers over 100 million dollars on Ethereum

Token launches face a fundamental pricing problem that no existing mechanism fully solves. The problem is two-sided: set the initial price too low and programmatic bots extract the difference instantly ($100M+ lost on Ethereum mainnet, $400M+ including MEV); set it too high and nobody buys. Static bonding curves (pump.fun, friend.tech) don't solve this because their ascending price structure guarantees that the first buyer gets the best deal — which is why bots dominate first-mover advantage.

**This is an auction design problem, not an engineering problem.** The core issue is incentive compatibility: static bonding curves reward speed over information. The first buyer captures the most value regardless of how informed they are. This creates a race condition where bots with latency advantages extract value that should accrue to the project and its informed supporters. The mechanism design question is how to create conditions where participants reveal their true valuations — analogous to how Vickrey (second-price sealed-bid) auctions make truthful bidding a dominant strategy.

**The mechanism: dutch auction + bonding curve hybrid.**

Doppler (Whetstone Research, built on Uniswap v4 hooks) combines two well-studied primitives into a two-phase price discovery system:

1. **Phase 1 — Dutch auction (descending).** Token price starts high and decays until buyers emerge. Dutch auctions are "shill-proof" (Komo et al 2024) — the descending price structure incentivizes truthful valuation revelation because the cost of bidding above your true value is directly borne by you. Buyers who enter early overpay; buyers who wait risk missing the clearing price. This creates a tension that converges on true valuation — similar in spirit to the revelation principle, where the mechanism makes honest participation individually rational. The descending structure also mitigates information asymmetry because bid revelation carries explicit costs through gas fees.

2. **Phase 2 — Dynamic bonding curve (ascending).** Once a clearing price is established, the bonding curve takes over, ramping price upward as supply is absorbed. The curve's position shifts via a `tickAccumulator` that integrates adjustments from both the auction and supply-side dynamics. This phase functions as a standard bonding curve but *starting from a market-discovered price* rather than an arbitrary initial value — the key improvement over static implementations.

**Epoch-based rebalancing creates adaptive price adjustment.** The protocol tracks expected vs actual token sales on a predetermined schedule and adjusts in three states: (a) severely undersold → maximum price reduction per epoch, (b) moderately undersold → proportional discount, (c) oversold → price increase toward expected clearing point. This creates a continuous feedback loop between supply schedule and market demand — the price doesn't just follow a predetermined curve, it adapts to actual buyer behavior.

**Three-slug liquidity structure provides exit depth.** Liquidity is positioned in three contiguous zones: a lower slug absorbing all proceeds (enabling redemption), an upper slug supplying near-term demand, and price discovery slugs provisioning future epochs. This means buyers always have exit liquidity — a structural improvement over bonding curves where selling into thin lower positions creates high slippage.

**MEV protection through hook architecture.** Bonding curve rebalances execute in the `beforeSwap` hook — meaning the curve shifts *during* transaction execution, not between blocks. Manipulators lose funds from curve movement that functions as limit orders against them. Multi-block MEV attacks would need to censor transactions across blocks *and* epochs — impractical on chains with censorship resistance.

**Why this matters for the internet finance thesis:** The existing knowledge base captures the *governance* layer of permissionless launches (futarchy, conditional markets, brand separation) and the *capital formation* layer (compressed fundraising, solo founders). Doppler operates at the *price discovery* layer — the infrastructure beneath governance that determines how tokens find their initial price and generate sustainable liquidity. If futarchy governs *whether* a project should launch, dutch-auction bonding curves govern *how* it prices. The two are complementary, not competing.

**Critical challenge: dutch auctions penalize true believers.** In traditional auctions (art, spectrum), making the highest-value bidder pay the most is allocatively efficient. But token launches aren't traditional auctions — the early buyers who value the token most are typically the project's most committed supporters, the ones who will hold, build community, and evangelize. A dutch auction makes these true believers pay the highest price while latecomers who waited (less conviction, less community alignment) get better deals. This inverts the community-building incentive: the mechanism optimizes for price discovery accuracy at the expense of rewarding early conviction.

Static bonding curves have the *opposite* problem — they reward early participation but are exploitable by bots who aren't genuine supporters. The unsolved mechanism design question is: **how do you reward genuine early conviction while protecting against bot extraction?** Neither dutch auctions nor static bonding curves solve both simultaneously. Possible approaches that haven't been fully explored:
- Futarchy as a pre-filter (governance decides *whether* to launch, then a community-friendly pricing mechanism handles *how*)
- Identity-gated or reputation-weighted participation that distinguishes bots from genuine community
- Hybrid mechanisms that offer early-supporter pricing to verified community members while using dutch-auction dynamics for the open market
- Conviction-weighted pricing where holding duration or governance participation earns retroactive discounts

**The best price discovery mechanism for token launches remains an open problem.** Doppler solves the arbitrage/MEV problem but may create a community alignment problem. The ideal mechanism would be shill-proof (no bot advantage), community-aligned (true believers get rewarded), and price-discovering (finds the right clearing price). No existing implementation achieves all three.

**Deployment limitation:** Doppler is live on Base/EVM and building for Solana (native SVM implementation, not a port). No on-chain data yet for Solana deployment. The $100M+ arbitrage figure is Ethereum-specific and may not directly translate to Solana where transaction ordering works differently.
