Mute Switch

Mute Switch (typically referred to as “Mute.io” or “Mute Switch”) is one of the earliest native decentralized exchanges on zkSync Era — offering a constant-product AMM with a distinctive dual-token model (MUTE for liquidity incentives and SWITCH for governance/protocol revenue), alongside a bond system that sells discounted MUTE to grow protocol-owned liquidity, positioning it as a hybrid AMM-plus-protocol-owned-liquidity model on zkSync.

Overview

Mute Switch launched on zkSync Era as one of the first DEX deployments on the network, capitalizing on early adopter position to accumulate liquidity before the competitive landscape emerged. Drawing inspiration from OlympusDAO’s bond mechanics and standard ve(3,3) tokenomics, Mute Switch differentiated itself from pure CLMM competitors like iZUMi Finance by targeting a broader range of trading pairs including volatile/volatile pairs — not just stablecoin or correlated asset pools.

The protocol’s bond mechanism was a notable feature: rather than emitting MUTE via standard liquidity mining, Mute allowed users to purchase MUTE at a discount in exchange for LP tokens — essentially selling tokens below market price to acquire LP positions that become protocol-owned liquidity (POL). This reduced the “mercenary capital” rotation typical of pure liquidity mining farms.

Dual-Token Model

Token design and economics are covered in detail below.

MUTE Token

MUTE is the primary liquidity incentive token:

  • Emitted to liquidity providers as rewards for depositing in Mute Switch pools
  • Can be purchased via the bond system at a discount (paying with LP tokens)
  • Staked to earn protocol fees and participate in dMUTE staking mechanics
  • Fixed supply with emission schedule weighted toward early liquidity providers

SWITCH Token (Governance)

SWITCH represents protocol governance:

  • Acquired by locking MUTE for fixed periods
  • Voting power determines fee distribution and pool gauge weights
  • Revenue sharing: SWITCH holders receive a portion of protocol trading fees
  • Lock durations vary; longer locks = more SWITCH per MUTE locked

dMUTE (Staking Derivative)

A staked form of MUTE:

  • Users lock MUTE → receive dMUTE (non-transferable staking receipt)
  • dMUTE accrues trading fee revenue in real assets (USDC, WETH)
  • Represents the “real yield” side of the Mute ecosystem

AMM Mechanics

Mute Switch uses constant-product AMM pools (x×y=k):

  • Standard 0.3% fee for volatile pairs; lower fees for stable-correlated pairs
  • Concentrated liquidity was not the primary product at launch (differentiating from iZUMi)
  • Simple UX targeting users who wanted broad liquidity access across zkSync tokens without sophisticated LP management

Bond System (Protocol-Owned Liquidity)

Inspired by OlympusDAO / Bond Protocol:

  • Protocol sells MUTE at 5–15% discount to market price
  • Users pay in LP tokens (e.g., MUTE-WETH LP)
  • Protocol retains LP tokens as POL — permanently farming its own fees
  • Reduces circulating LP supply, making remaining LP positions more stable
  • Bond pricing adjusts dynamically based on demand

zkSync Era Integration

Mute Switch leveraged zkSync Era’s native transaction cost advantages:

  • Lower gas fees allowed smaller LPs to participate economically
  • zkSync Era’s paymaster system allowed fee abstraction
  • Protocol positioned itself as the “default AMM” on zkSync before larger protocols deployed
  • As Uniswap V3, Maverick Protocol, and other established DEXes deployed on zkSync, Mute faced increased competition
