What is BOLD Stablecoin (BOLD)?

Quick Facts

  • Issuer: Liquity Protocol V2 on Ethereum
  • Peg: 1 BOLD = $1 USD
  • Collateral types: ETH, wstETH, rETH
  • Collateral model: Overcollateralized crypto-only (no real-world assets)
  • Smart contracts: Immutable — no admin keys or upgrades
  • Governance: Governance-free protocol design
  • Rating: A- from Bluechip, outranking USDC and DAI

Introduction

BOLD is a fully redeemable, USD-pegged decentralized stablecoin issued by Liquity Protocol V2. It is backed entirely by crypto assets and operates on Ethereum through immutable smart contracts.

Unlike many stablecoins that rely on banks, custodians, or governance committees, BOLD is designed so users only need to trust the code — not any intermediary.

History & Background

Liquity Protocol first launched V1 with its original stablecoin, LUSD, built on zero-interest borrowing using ETH as collateral. V2 was introduced to expand on this foundation, bringing BOLD as the next-generation stablecoin with greater flexibility and a richer feature set.

BOLD introduced support for liquid staking tokens (LSTs) as collateral, user-defined interest rates, and a yield-bearing Stability Pool — all while preserving Liquity's core principle of immutability.

How BOLD Stablecoin Works

Users open a collateralized debt position called a Trove by depositing ETH, wstETH, or rETH. Against this collateral, they borrow (mint) BOLD tokens. Each Trove must maintain a minimum collateral ratio to remain solvent.

A key innovation in V2 is that borrowers set their own interest rates, creating a market-driven dynamic for borrowing demand. The system maintains the $1 peg through overcollateralization, a direct redemption mechanism, and a Stability Pool where BOLD holders earn yield from liquidations and accrued interest.

All protocol revenue — 100% — flows back to Stability Pool stakers, creating a sustainable, self-contained yield loop.

Tokenomics

BOLD is minted when users borrow against their collateral and burned when debt is repaid. There is no fixed issuance schedule — supply expands and contracts organically with borrowing demand.

The economic design routes all protocol fees directly to BOLD stakers in the Stability Pool, eliminating reliance on token inflation for yield. This 'real yield' model aligns incentives between borrowers, stakers, and the long-term health of the protocol.

Ecosystem & Use Cases

BOLD can be freely transferred to any Ethereum address regardless of whether the holder has an open Trove. Core use cases include:

  • Borrowing: Mint BOLD against crypto collateral with self-chosen interest rates
  • Earning: Deposit BOLD into the Stability Pool to earn yield from protocol fees and liquidations
  • DeFi integration: Use BOLD as a stable unit of account across other DeFi protocols

Multiple community-operated frontends provide access to the protocol, including Liquity.App, DeFi Saver, and others.

Team, Governance & Community

Liquity was founded by Michael Svoboda and is developed by Liquity AG. The protocol is purposely designed to be governance-minimized — there are no admin keys, multisigs, or upgradeable contracts after deployment.

Community participation happens through Protocol Incentivized Liquidity (PIL) governance, which directs liquidity incentives to ensure sufficient BOLD liquidity across the ecosystem.

Advantages

  • Fully decentralized: Backed only by crypto assets with no off-chain custodians
  • Immutable contracts: No risk of parameter changes or protocol interference post-deployment
  • Direct redemption: BOLD is always convertible for its underlying collateral value
  • Real yield: 100% of protocol revenues distributed to Stability Pool stakers
  • User-controlled rates: Borrowers set their own interest rates for maximum flexibility
  • High trust rating: Received an A- from Bluechip with perfect scores for decentralization and governance

Risks & Challenges

  • Immutability trade-off: No ability to patch smart contract vulnerabilities post-deployment
  • Collateral volatility: Sharp drops in ETH or LST prices can trigger liquidations
  • Adoption competition: Competes with established stablecoins like USDC, DAI, and newer entrants
  • Liquidity depth: As a newer stablecoin, liquidity across DeFi venues is still growing

Long-Term Vision

Liquity's vision for BOLD is to serve as a credibly neutral, crypto-native stablecoin that meets the needs of DeFi power users, funds, and institutions — without relying on banks or central issuers. By remaining immutable, fully on-chain, and governance-minimized, BOLD aims to offer a predictable and censorship-resistant stable asset that can thrive in even the most adversarial environments.

Frequently Asked Questions

BOLD is a USD-pegged stablecoin used for borrowing against crypto collateral on Liquity V2 and for earning yield by depositing into the Stability Pool. It can also be used as a stable medium of exchange or unit of account across DeFi protocols.

BOLD is backed exclusively by crypto assets: ETH, wstETH (wrapped staked ETH), and rETH (Rocket Pool ETH). No real-world assets or centralized custodians are involved.

The peg is maintained through overcollateralization, a direct redemption mechanism that lets holders exchange BOLD for underlying collateral at face value, and an adaptive interest rate system that manages borrowing demand.

A Trove is an individual collateralized debt position where a user deposits crypto assets and borrows BOLD against them. Each Trove must keep its collateral ratio above the protocol minimum or risk liquidation.

Yes. Users can deposit BOLD into the Stability Pool to earn yield generated from borrower interest payments and liquidation proceeds. All 100% of protocol revenues are directed to Stability Pool stakers.

The core protocol is immutable and governance-free — no admin keys or multisigs can change its parameters. There is a limited governance mechanism called Protocol Incentivized Liquidity (PIL) for directing liquidity incentives.

BOLD is the V2 upgrade to LUSD. It adds support for liquid staking tokens as collateral, allows borrowers to set their own interest rates, and introduces a yield-bearing Stability Pool funded by protocol revenues.

Yes. BOLD received an A- rating from Bluechip, a stablecoin rating agency, with perfect scores for decentralization and governance — ranking it above established stablecoins like USDC and DAI.
