What is Ion Protocol (ION)?

🟢 The simple version
Plain English — no jargon. Start here.
Ion Protocol is an Ethereum lending protocol specialising in Liquid Staking Tokens (LSTs) and Liquid Restaking Tokens (LRTs) as collateral — while most lending protocols treat stETH and eETH as risky exotic collateral, Ion is designed specifically for these assets, offering more capital-efficient borrowing against LST/LRT positions.
The LST/LRT lending gap
Aave and other general lending protocols are conservative with LST/LRT collateral. They set low LTV ratios for stETH, rETH, and restaked ETH tokens because these assets have slashing risk (validator penalties), liquidity risk (they can depeg from ETH in stress events), and smart contract risk (they're more complex than plain ETH). Ion Protocol accepts that these risks exist but argues that generic lending protocols are too conservative — they treat all LST/LRT risk as the same when in reality, highly liquid, well-audited LSTs like stETH deserve better collateral treatment than illiquid, newer LRTs.
Ion's innovation: a risk-adjusted lending system specifically calibrated for LST/LRT collateral. Rather than using one conservative LTV for all LSTs, Ion models the specific risks of each LST — validator set quality, slashing history, liquidity depth, smart contract audit status — and sets collateral parameters accordingly. Well-established LSTs (stETH) get better terms; higher-risk LRTs get more conservative terms.
ION token
ION is the governance token of Ion Protocol. It controls: which LST/LRT assets are accepted as collateral, the risk parameters for each, and protocol fee settings. ION launched in 2024.
Is ION legal in India?
Yes. ION qualifies as a Virtual Digital Asset (VDA) under Indian law. 30% tax on gains and 1% TDS applies. Always consult a tax professional.

Ion vs Morpho for LST collateral
Morpho Blue supports LST collateral (there are MetaMorpho vaults with stETH collateral) and gives curators flexibility to set their own parameters. Ion is more specialised: the entire protocol is designed around the unique characteristics of staked ETH assets — their yield (which makes them appreciating collateral), their correlation (they all track ETH price), and their specific risk vectors (slashing, contract risk). Ion can be thought of as the specialist and Morpho as the generalist in this space. For large LST/LRT holders wanting maximum borrowing efficiency, Ion's specialisation potentially offers better terms.
LRT-specific risk modelling
Liquid Restaking Tokens (LRTs) — like eETH (EtherFi), ezETH (Renzo), weETH (EtherFi), and similar — add restaking risk on top of base staking risk. A restaked ETH token can be slashed both at the base Ethereum validator level AND at the EigenLayer AVS (Actively Validated Service) level. Ion's risk models incorporate both slash risk layers when determining LRT collateral factors. This dual-risk modelling is absent in general lending protocols that simply apply a blanket conservative LTV to all "exotic" collateral.
Ion is a relatively new protocol accepting collateral types (LRTs) that are themselves new. LRTs have not been through a major market stress event — their depegging behaviour, liquidity under pressure, and slashing mechanics are less understood than plain LSTs. Protocols that accept LRT collateral are taking frontier risk. Monitor Ion's bad debt history and insurance fund as primary health indicators. Live data: CoinGecko

For the technically curious.
Key facts
- Token: ION (governance)
- Function: LST/LRT-specialised lending protocol
- Chain: Ethereum
- Supported collateral: stETH, rETH, eETH, weETH, ezETH, and other LSTs/LRTs
- Key differentiation: Asset-specific risk parameters for each LST/LRT
- vs Aave: More capital-efficient for LST/LRT holders (higher LTVs for established LSTs)
- vs Morpho: More specialised (LST/LRT only) vs Morpho's general lending infrastructure
- Target users: Large stETH/eETH holders wanting to borrow efficiently against their position
- Risk model: Dual-layer slashing risk for LRTs (base + restaking)
Yield-bearing collateral accounting
A key characteristic of LST/LRT collateral: it appreciates over time (stETH grows vs ETH as staking rewards accrue). Ion's collateral accounting incorporates this: the LTV ratio is calculated against the current exchange rate of the LST vs ETH, not a fixed value. As stETH accrues yield, the borrower's health ratio improves automatically — the collateral is self-strengthening over time. This is in contrast to standard lending protocols where ETH collateral is static. Ion's model recognises that 1 stETH today will be worth more ETH in a year, and factors this into risk calculations.
