The Cost of Inefficiency: Wasted Gas in Peg Arbitrage Wars
An analysis of the systemic waste generated by MEV bots during stablecoin peg events, quantifying the deadweight loss and exploring architectural solutions to redirect this energy towards actual stability.
introduction
THE DATA
Introduction
Peg arbitrage on cross-chain bridges incurs billions in wasted gas, a direct tax on user liquidity.
The arbitrage war is a gas-guzzling race. Protocols like Stargate and Across incentivize bots to compete for the same arb, burning fees without adding new value to the system.
This is a structural subsidy for validators, not users. The wasted gas from millions of failed front-run transactions on Ethereum and Arbitrum represents pure economic leakage from the DeFi ecosystem.

THE REAL COST OF ARBITRAGE
Executive Summary
Cross-chain peg arbitrage is a multi-billion dollar game of speed, where the network's security budget is burned as wasted gas.
01
The Problem: MEV as a Public Good Drain
Arbitrage bots competing for cross-chain price discrepancies turn block space into a zero-sum battlefield. The value captured by searchers is dwarfed by the gas fees burned in the process, representing a direct tax on the protocol's security budget and user experience.\n- $100M+ in gas wasted annually on mainnet arbitrage\n- >50% of profitable opportunities lost to gas wars\n- Creates systemic latency and fee pressure for all users

The Solution: Intent-Based Settlement
Shifting from transaction-based to intent-based architectures (e.g., UniswapX, CowSwap) outsources routing and execution. Users express a desired outcome, and a network of solvers competes off-chain to fulfill it at the best rate, batching and optimizing execution.\n- Eliminates frontrunning and gas auction wars\n- Captures ~99% of available arbitrage value for users/solvers\n- Enables cross-chain swaps without user-side bridging complexity

The Enabler: Shared Sequencing & Atomicity
True cross-chain atomic composability requires a shared sequencing layer or secure messaging protocol (e.g., LayerZero, Chainlink CCIP). This guarantees that a series of actions across chains either all succeed or all fail, removing settlement risk and enabling new primitive designs.\n- Enables trust-minimized cross-chain DeFi lego\n- Reduces arbitrage latency from minutes to ~seconds\n- Unlocks native yield and collateral mobility across ecosystems

The Result: From Rent Extraction to Value Creation
Eliminating inefficient arbitrage transforms the economic model. Value previously burned as gas is redirected to protocol fees, solver incentives, and user savings. This creates a sustainable flywheel for cross-chain infrastructure instead of a public good drain.\n- Protocols capture fees from efficient value flow\n- Users receive better prices with predictable costs\n- Ecosystem security is strengthened, not diluted

The Current State of Peg Wars
Peg arbitrage wars are a systemic drain, burning millions in gas for zero-sum rebalancing across fragmented liquidity pools.
Peg maintenance is a tax. Every time a stablecoin deviates, arbitrage bots compete to correct it. This competition burns gas on Layer 1s like Ethereum for a transfer of value, not creation. The winner's profit is the loser's cost plus the network's burnt fees.
The fragmentation is the problem. Each new bridge (LayerZero, Circle CCTP) and chain (Arbitrum, Base) creates new liquidity silos. Arbitrageurs must bridge assets between these pools, multiplying the gas expenditure needed to maintain a single global peg.
Evidence: In Q1 2024, over $3.5M in gas was spent on USDC/USDT arbitrage alone. This capital was incinerated by bots racing across Uniswap, Curve, and Aave pools on a dozen different chains.

THE DATA
Anatomy of a Failed Transaction
Peg arbitrage wars waste millions in gas on failed transactions that never secure profits.
Failed transactions dominate gas spend. Over 50% of gas on major bridges like Stargate and Across funds arbitrage bots that revert. This is pure waste, not economic activity.
Arbitrage logic is front-run. Bots use identical strategies from public mempools. The result is a gas auction where only the fastest transaction succeeds; all others fail and burn fees.
MEV searchers are the primary culprits. Protocols like Flashbots and bloxroute enable this arms race. Their private order flow creates a zero-sum game for the network.
Evidence: On Arbitrum, over $3M in gas was wasted in one month by failed arbitrage transactions targeting the USDC de-peg, per Flipside Crypto data.

Architectural Experiments: Redirecting the Fire
Peg arbitrage is a necessary market function, but on-chain execution wastes millions in gas and creates systemic fragility.
01
The Problem: On-Chain Slippage & MEV Burn
Every peg arbitrage trade on a DEX like Uniswap V3 is a public, gas-bidding war. Bots spend $50M+ annually on gas** just to correct stablecoin prices, a pure deadweight loss. This creates negative-sum competition where value is extracted by validators, not returned to users or protocols.

The Solution: Intent-Based Settlement
Shift from transaction-based to outcome-based execution. Protocols like UniswapX and CowSwap let users express a desired end state (e.g., '1 USDC for >=0.999 DAI'). Solvers compete off-chain, submitting only the optimal, settled bundle, eliminating on-chain bidding wars and capturing that value for users.

The Architecture: Cross-Chain Atomic Arbitrage
Inefficiency peaks in cross-chain peg maintenance. Native solutions like LayerZero's OFT and intent-based bridges like Across enable atomic, multi-chain rebalancing. A single, coordinated action across chains replaces dozens of fragmented, competing transactions, dramatically reducing systemic latency and cost.

The Endgame: Protocol-Owned Liquidity & Vaults
The most radical efficiency is eliminating the arb opportunity itself. Protocols like MakerDAO with PSM or Aave's GHO with direct mint/burn mechanics internalize peg stability. Coupled with Curve's crvUSD LLAMMA, which uses vaults as automatic market makers, the need for public arbitrage is structurally reduced.

THE INEFFICIENCY TAX
The Path Forward: From Waste to Work
Peg arbitrage wars consume billions in gas for zero-sum rebalancing, a systemic tax that can be redirected into productive computation.
Peg arbitrage is pure waste. Bots on Ethereum and L2s burn gas to capture fractions of stablecoin depegs, a zero-sum economic game that produces no new value. This is a systemic inefficiency tax paid by all users through base fee inflation.
The capital is idle and reactive. Billions in stablecoin liquidity sits on bridges like LayerZero (Stargate) and Across, waiting for a depeg signal. This capital does no productive work between arbitrage cycles, representing massive opportunity cost.
Redirect gas to useful state. Instead of burning ETH to rebalance USDC, that computational energy should execute verifiable work. Protocols like EigenLayer and AltLayer demonstrate the model: stake secures new services. Peg maintenance is a prime candidate for restaking.
Evidence: Over $15M in gas was spent on the March 2023 USDC depeg. A verifiable attestation network powered by restaked ETH would have settled the peg for <$10k, freeing the remainder for ZK-proof generation or AI inference.

Key Takeaways
Peg arbitrage is a necessary but wasteful mechanism, burning millions in gas to maintain price parity between assets.
01
The Problem: Redundant On-Chain Execution
Every arbitrage trade executes the same logic—swap, bridge, swap—on-chain, paying for computation and state updates that provide no new information to the network. This is a pure deadweight loss.
- Wasted Gas: An estimated $50M+ annually is spent on redundant MEV bot transactions.
- Network Congestion: These transactions compete for block space, increasing fees for all users.

The Solution: Intent-Based Architectures
Frameworks like UniswapX and CowSwap shift the burden of route discovery and execution off-chain. Users submit a desired outcome (an 'intent'), and a network of solvers competes to fulfill it optimally.
- Gas Abstraction: The user pays no gas for failed paths or inefficient routing.
- Efficiency Gain: Solvers batch and optimize execution, reducing total network load by ~40-60% for cross-chain swaps.

The New Primitive: Verified Off-Chain Computation
Protocols like Across and Chainlink CCIP use off-chain actors (oracles, relayers) to compute optimal routes and attest to correctness. The on-chain contract only needs to verify a cryptographic proof.
- Cost Structure: Pay for verification, not computation. This is 10-100x cheaper.
- Security Model: Shifts trust from LPs and bridge validators to economic security of attestation networks.

The Endgame: Native Cross-Chain Synchronization
The ultimate efficiency is eliminating the peg altogether. LayerZero's Omnichain Fungible Tokens (OFTs) and Cosmos IBC treat assets as single tokens natively mintable/burnable across chains.
- Zero Arbitrage: No price delta means no arbitrage wars.
- Native Efficiency: Transfers become simple message-passing, reducing cost to basic bridge fees.
