Ionic Protocol

Ionic Protocol is the primary decentralized lending protocol on Mode Network — a Compound V2 fork adapted for Mode’s Ethereum L2 environment, enabling overcollateralized borrowing against USDC, WETH, weETH, and Mode-native tokens, distributing ION governance tokens to incentivize market participation, and integrating with Mode’s native sequencer fee sharing and EigenLayer restaking token collateral as distinctive features of the Mode ecosystem.

Overview

Ionic Protocol fills the money market role for Mode Network — a Superchain L2 built on the OP Stack that differentiates through native sequencer fee sharing with protocols and users (Mode distributes a portion of sequencer revenue back to protocols and end users who generate activity). Ionic, as the primary lending protocol, participates in this revenue sharing while providing standard overcollateralized lending infrastructure.

A distinctive feature of Mode’s ecosystem is its early adoption of EigenLayer liquid restaking tokens (LSTs like weETH from EtherFi, rsETH from KelpDAO) as collateral — targeting the growing “restaked ETH” narrative where users hold restaking tokens that generate EigenLayer rewards and want to borrow against them without selling.

Core Architecture

The protocol is built around the following components.

Compound V2 Foundation

Ionic uses the Compound V2 codebase as its base:

  • iTokens — Ionic’s interest-bearing deposit tokens (iUSDC, iWETH, iweETH) that appreciate in value as interest accrues
  • Borrow with collateral; health factor below 1.0 triggers liquidation
  • Standard two-slope interest rate model (slow rate increase below optimal utilization; steep above)
  • Permissionless pool creation for custom risk configurations

Supported Markets

Core Mode Network assets:

  • USDC — primary stable borrow market (most demand from leveraged traders)
  • WETH — ETH-denominated lending and borrowing
  • weETH (EtherFi) — wrapped restaking ETH with EigenLayer rewards; accepted as collateral
  • rsETH (KelpDAO) — another EigenLayer liquid restaking token; collateral support
  • WBTC — Bitcoin-pegged asset (bridged to Mode)
  • MODE token — volatile governance token; lower LTV collateral option

EigenLayer Restaking Token Integration

A defining feature of Ionic on Mode:

Restaking Token Collateral

EigenLayer liquid restaking tokens (LRTs) like weETH generate multiple yield streams:

  1. ETH proof-of-stake staking yield (~3-5% APR)
  2. EigenLayer operator fees from services secured by restaked ETH
  3. EigenLayer EIGEN token distribution events

Ionic enables weETH, rsETH, and similar tokens as collateral:

  • Users hold restaking tokens and continue earning EigenLayer yields
  • Simultaneously use restaking tokens as Ionic collateral to borrow USDC or WETH
  • Use borrowed assets for additional DeFi strategies
  • Net result: layered yield — restaking + borrowing + farming borrowed assets

Risk Consideration

  • LRTs carry additional risk beyond standard ETH: slashing from EigenLayer Operators, potential smart contract bugs in restaking protocols
  • Ionic assigns lower LTV (typically 65-70%) to LRT collateral vs standard WETH (75-80%)
  • Price oracle uses TWAP — LRT price generally tracks ETH × (1 + restaking premium)

ION Token

ION is Ionic’s governance and incentive token:

  • Distributed to both lenders and borrowers in incentivized markets
  • ION stakers earn protocol fee revenue (portion of interest spread)
  • Governance: ION holders vote on risk parameters, new market listings, emission weights
  • Participation in Mode Network’s native airdrop campaigns (Mode Ecosystem Fund integration)

Mode Network Sequencer Fee Sharing

Mode Network uniquely distributes sequencer revenue to active protocols and users:

  • Protocols that generate user activity on Mode earn a share of sequencer fees
  • Ionic, as a high-activity lending protocol, receives sequencer fee distributions
  • Fee sharing creates a non-token revenue stream supplementing ION incentives
  • Distributed to ION stakers or Ionic treasury per governance decisions
