# Why Synchronization?

> Onchain markets have no shared price layer. Regulation can mandate best execution; only infrastructure can deliver it.

## Traditional markets did not stay synchronized by accident

They were forced into one price by regulation and shared infrastructure over fifty years: central clearing (<Tooltip tip="Depository Trust Company / National Securities Clearing Corporation, established 1973.">DTC/NSCC</Tooltip>, 1973), the <Tooltip tip="A single feed aggregating best bid/ask and last-sale data across all U.S. exchanges.">consolidated tape</Tooltip> and quotation system (1976), the <Tooltip tip="National Best Bid and Offer: the best available buy and sell prices across all exchanges at any moment.">national best bid and offer</Tooltip> under Reg NMS (2005), and the order protection rule that barred fills at worse-than-best prices (2007).

Crypto has none of this. There is no consolidated tape, no NBBO, no matching engine spanning venues. And the regulatory direction is moving away from mandated synchronization, not toward it: the SEC is proposing to rescind <Tooltip tip="The SEC order protection rule requiring trades to execute at the best available price across exchanges.">Rule 611</Tooltip> (the order protection rule), while the CLARITY Act and NYSE's pairing of its Pillar matching engine with onchain settlement signal that serious volume is coming onchain without the infrastructure to keep it synchronized.

The conclusion: **synchronization must now come from onchain infrastructure.**

## The problem: 900+ venues, no shared price

Every onchain venue prices independently. Venues refresh anywhere from approximately 400ms to 60s apart, with slower venues carrying staler prices. There are 900+ DEXes across 500+ chains, each quoting the same asset at its own price. There is no onchain reference price to keep them in sync. Fragmentation is accelerating: every new venue adds another disconnected price for every asset.

## Who loses, and how much

Roughly **\$3B leaks per year** from unsynchronized markets. The cost shows up differently for each participant, but the root cause is the same: stale, uncoordinated prices.

  <Accordion title="Liquidity providers" icon="droplet" defaultOpen={true}>
    Passive AMM LPs are picked off by better-informed arbitrageurs whenever the pool price is stale relative to the true market. This <Tooltip tip="Loss-versus-rebalancing: the cost passive AMM LPs pay when arbitrageurs extract value from stale pool prices. Persists even when prices revert.">loss-versus-rebalancing</Tooltip> persists even when prices revert, because value was already extracted during rebalancing. Estimates put LVR at **5 to 11 percent** of provided capital per year for volatile pairs. Uniswap v3 ETH/USDC LPs have lost on the order of **\$100M** after fees versus simply holding.

  <Accordion title="Traders" icon="arrow-right-arrow-left">
    Predictable AMM curve pricing and public mempools expose users to sandwiching and <Tooltip tip="Maximal Extractable Value: the profit validators or searchers can extract by reordering, inserting, or censoring transactions within a block.">MEV</Tooltip> extraction. In 2025, sandwich attacks accounted for approximately **\$290M,** about 52 percent of total MEV volume. Over **\$500M** was extracted from Solana users alone between January 2024 and May 2025. The precondition is stale, exploitable onchain prices.
  </Accordion>

  <Accordion title="Protocols" icon="shield-halved">
    Lending, perps, and vault protocols depend on price feeds that report past prices and can be stale, misconfigured, or single-source. Moonwell took approximately **\$1.78M** in bad debt after a cbETH oracle misconfiguration. Aave saw approximately **\$27M** of erroneous wstETH liquidations from a stale CAPO oracle parameter. Both are part of a recurring pattern. Unsynchronized prices amplify flash-crash liquidation cascades: a small order against a weak price reference can cascade into system-wide forced liquidations.
  </Accordion>

  <Accordion title="Ecosystems" icon="globe">
    Without synchronization, an asset can be listed onchain but not truly usable. Prices differ across venues, collateral cannot be trusted, liquidations have no clear price to execute against, and routers split or route around the asset. Synchronization is the difference between an asset being listed and being usable financial infrastructure.

## The resolution

The Convergence Engine builds a fair price from a cross-venue composite, forecasts its near-term path, and posts one executable convergence price onchain. The engine prices. The pool settles.

Zero slippage is a consequence of convergence pricing. When the engine forecasts where the composite is headed and quotes that price, the gap between quoted price and fill price closes.
