Liquity, Explained

Arrr, here be yer pillar page, scribed in the voice of a seasoned DeFi editor rather than a scurvy sea dog — the article itself must read shipshape and authoritative, aye!

Liquity is a non-custodial borrowing protocol on Ethereum that lets users mint the BOLD stablecoin against ETH and liquid staking tokens (LSTs), with no admin keys, no governance fee switches, and immutable smart contracts.

Built around a single guiding principle — that trustlessness is a verifiable on-chain property, not a marketing claim — Liquity has become a reference design for the decentralized stablecoin category and a starting point for over a dozen forks across EVM chains.

What Is Liquity?

Liquity launched its first version in April 2021 with a narrow but radical proposition: let users borrow a USD-pegged stablecoin (LUSD) against ETH at zero ongoing interest, paying only a one-time origination fee. The protocol was immutable from day one — no team multisig, no DAO vote, no emergency pause. Whatever the code said on deployment day, it would say forever.

Liquity V2, released in 2024, extended the model materially. The new stablecoin is BOLD, superseding LUSD. Accepted collateral expanded from ETH alone to include major liquid staking tokens — principally wstETH (Lido's wrapped staked ETH) and rETH (Rocket Pool ETH). Most significantly, V2 replaced the one-time fee model with user-set annual interest rates, giving borrowers direct control over their cost of capital and their redemption-queue position.

BOLD crossed the LUSD circulating supply figure in 2025, marking the effective hand-off from the first generation to the second.

This is a good partnership and I hope the dividend from it favours the users

BOLD: A Stablecoin Without an Off Switch

BOLD is a soft USD-pegged stablecoin backed exclusively by ETH and ETH-based LSTs. It carries no blacklist function, no freeze capability, and no admin key that could block a wallet from transacting. These properties set it apart from every fiat-backed stablecoin (USDC, USDT, PYUSD) and from partially centralized decentralized stablecoins — even MakerDAO's DAI holds real-world assets and retains emergency governance levers.

In 2025, Bluechip — an independent stablecoin rating organization — awarded BOLD an A- rating, the first decentralized stablecoin to achieve that grade. Bluechip's methodology gave BOLD perfect 1.0 scores in Management, Decentralization, and Governance. The agency explicitly noted that BOLD cannot be frozen and has no admin keys. Bluechip's analysis also named the corresponding tradeoff plainly: smart-contract risk substitutes for counterparty risk. With no human override, a code exploit cannot be patched retroactively.

That tension is central to understanding Liquity. The protocol is not trying to eliminate risk; it is trying to make the risk legible, on-chain, and consistent — properties that are absent when a centralized party can unilaterally freeze assets.

An April 2025 satirical piece circulated claiming Circle had acquired Liquity to add non-freezable stablecoin technology to USDC. Published on April 1, the premise landed as obvious contradiction — Circle's entire business model depends on issuer control over USDC — and the joke spread precisely because it illustrated how far Liquity's design sits from the fiat-backed mainstream.

How Borrowing Works

Borrowing on Liquity V2 follows a collateralized debt position (CDP) model. A user deposits ETH or an accepted LST into a trove — the protocol's term for a CDP — and mints BOLD up to the trove's loan-to-value ceiling. Key LTV limits in the base Ethereum deployment:

• ETH: up to 91% LTV
• wstETH / rETH: up to 83.33% LTV

These ceilings are high relative to most DeFi lending markets, where 70–80% for ETH is typical. The tradeoff is meaningful: positions are subject to both liquidation (automatic if LTV breaches the ceiling) and redemption (when BOLD trades below $1, arbitrageurs redeem BOLD for collateral, starting with the lowest-rate troves first).

Interest rates are set by the borrower, not by a governance vote or algorithmic rate curve. A borrower who sets a low rate pays less but sits at the front of the redemption queue during a depeg event. A borrower who sets a higher rate is insulated from redemptions but pays more over time. This design turns interest rate selection into a form of position management.

Since launch, Liquity V2's average ETH borrowing rate has been approximately 2.82% — roughly 2 percentage points below the next competing protocol, and reportedly never above 6% even during sharp market moves. For protocol treasuries or DAOs seeking operational runway without liquidating ETH holdings, borrow-don't-sell is a practical use case the protocol actively addresses: borrow BOLD at a known rate, spend it, repay when convenient, maintain ETH exposure throughout.

Revenue Model: No Extraction

Liquity's alignment mechanism is uncommon in DeFi: the protocol extracts no revenue for itself. All yield generated within the system flows back to users. There is no protocol fee switch, no DAO treasury accrual, and no participation in revenue-sharing alliances (Liquity has explicitly declined frameworks that would require withholding a share of returns).

BOLD deposited in the Stability Pool earns yield from two sources: interest payments made by borrowers, and ETH gains absorbed when liquidated troves are processed. The Stability Pool acts as the protocol's first line of defense for solvency — it absorbs undercollateralized debt — and also as its primary passive yield venue.

The Curve Connection

Curve Finance has been Liquity's closest ecosystem partner from the beginning. Curve's StableSwap pools — optimized for assets that trade near parity — provided the primary deep liquidity venue for LUSD, and now serve the same function for BOLD. A stablecoin's peg stability is inseparable from its on-chain liquidity depth: thin liquidity amplifies depegs; concentrated liquidity absorbs them.

The relationship goes beyond technical integration. Representatives from Liquity, Curve, and f(x) Protocol formed the Trustless Force — a loose coalition advocating non-custodial, immutable stablecoin infrastructure on Ethereum. The group has participated in panels with the Ethereum Foundation and the DeFi Collective discussing decentralization standards, and hosted public discussions on "how trustless is DeFi?" with researchers from DeFi Scan. The Trustless Force framing — and the Bluechip A- rating — represent an attempt to formalize what "decentralized" actually means in a measurable way, rather than leaving it as a self-applied label.

Liquity V2's smart contracts are immutable and ungoverned — 100% of revenue flows to BOLD holders and Earn depositors with no DAO lever to redirect even if they wanted to. The DeFi United crew (Aave, Lido, EtherFi, Mantle, Ethena) all have governance tokens that can vote to deploy treasury for rescues; Liquity traded that flexibility for credible neutrality. The same composability that created the contagion risk requiring this $161M backstop is what Liquity refuses to participate in — TVL stuck at $24M is the price of isolation, but so is not being on the hook when KelpDAO's LayerZero adapter gets drained.

The Fork Ecosystem

Liquity's open-source, immutable codebase made V1 one of the most-forked protocols in DeFi. V2 was designed with forking explicitly in mind, and by mid-2025 the Liquity team reported over a dozen "friendly forks" building on the mechanism. A few illustrate the range:

Nerite (Arbitrum): A V2 fork targeting Arbitrum's ecosystem. Nerite reached mainnet deployment and subsequently launched a governance token, NERI, via a Balancer Liquidity Bootstrapping Pool. The team issued explicit warnings about scam tokens circulating before the real NERI launch — a recurring hazard in new token launches.

gEURO (Gnosis Chain): An active GnosisDAO governance proposal to fund a euro-pegged stablecoin using the Liquity V2 mechanism. The proposed stablecoin would be backed by ETH, BTC, and Gnosis-native assets, yield-bearing by default, and integrated with Gnosis Pay and real-world asset infrastructure. The proposal sought approximately $50,000 for audits and $5 million in launch liquidity.

Enosys: Announced an airdrop of 2.75% of its APS governance token supply to Liquity V2 mainnet liquidity providers, part of the incentive structures emerging around the fork ecosystem.

The fork dynamic is self-reinforcing: each deployment battle-tests the underlying mechanism under different market conditions, collateral types, and user bases, while the canonical Ethereum deployment captures primary liquidity and reputation effects.

Risks

No DeFi protocol eliminates risk; it redistributes it. For Liquity users, the key risks are:

Liquidation: If ETH or LST prices fall and a trove's LTV exceeds its ceiling, the position is liquidated automatically. During fast-moving markets, the window between price move and liquidation can be narrow.

Redemption: Borrowers at the lowest end of the interest rate queue are redeemed against first when BOLD depegs below $1. This means collateral is returned minus debt, but a borrower may not have chosen to close the position. The protocol includes a "loan shifter" tool to move debt between rates, but it requires active management.

Smart contract risk: Immutability prevents governance attacks but also prevents patches. If a critical vulnerability is found post-deployment, there is no emergency pause. Audits reduce this risk but cannot eliminate it. The Bluechip A- rating reflects this tradeoff explicitly.

LST-specific risk: Borrowing against wstETH or rETH introduces additional layers: the LST's own smart contracts, validator slashing risk, and the possibility that the LST/ETH exchange rate moves adversely. These risks are incremental to raw ETH collateral positions.

Volatility: High LTV ceilings mean that moderate price moves — not just extreme ones — can approach liquidation thresholds for borrowers near the maximum.

Governance Philosophy

Liquity's governance posture is deliberately minimalist. V1 had none whatsoever — no vote, no multisig, no upgradeable proxy. V2 permits limited configuration (interest rate bounds, collateral types) in new deployments, but the canonical Ethereum deployment is non-upgradeable after launch.

The philosophical argument, articulated publicly by Liquity CEO Michael Svoboda, is that governance is not a neutral safety mechanism — it is an attack surface. Protocols with governance can be subject to governance attacks, parameter manipulation, regulatory compulsion to blacklist addresses, and the slow accumulation of centralized control over supposedly decentralized systems. An immutable protocol offers a different guarantee: any user who can read Ethereum bytecode can independently verify that the rules will not change. That verifiability is the core claim.

Outlook

Liquity V2 crossed $160 million in TVL within its first year on mainnet, BOLD superseded its predecessor LUSD in circulating supply, and the fork count exceeded a dozen chains and projects — all while maintaining borrowing rates that have stayed below 3% on average since launch. The mechanism has been stress-tested through volatile markets without breaching 6% borrowing costs, a data point that the protocol's users and fork teams cite as meaningful evidence of stability.

The open questions are structural. Can non-custodial stablecoin liquidity scale to compete meaningfully with the depth of USDC and USDT on major DEXs and CEXs? Will regulators treat non-freezable stablecoins as a problem to be solved, a category to be avoided, or simply irrelevant given their current scale? And as the fork ecosystem matures — with euro-pegged, chain-specific, and asset-specific BOLD variants proliferating — will the canonical Ethereum deployment retain its centrality, or will liquidity fragment?

Liquity's bet is that trustlessness is durable precisely because it is hard to replicate: any competitor who adds an admin key, a fee switch, or a governance override gives up the property that defines the category. For users and treasuries who have decided counterparty risk is the risk they most want to avoid, that bet remains the point.
