Hedgehog Markets

TLDR: Hedgehog Markets is a permissionless prediction market platform built on Solana and Eclipse that lets anyone create and trade binary outcome markets on virtually any verifiable event — from crypto price levels and election results to sports outcomes and technology milestones — with sub-second settlement and fees under $0.01 per trade.

What Hedgehog Markets Is

Hedgehog Markets brings permissionless speculation to on-chain prediction markets. Where traditional or centralized prediction platforms curate a limited set of approved questions, Hedgehog allows any user to launch a market on any topic that has a verifiable outcome. The result is a long-tail catalogue of markets spanning politics, crypto, sports, technology, and anything else the community wants to price.

The platform operates on two blockchains: Solana as the primary settlement layer, and Eclipse — a Solana Virtual Machine (SVM)-compatible Ethereum Layer 2 — for users operating within the Ethereum ecosystem. Both deployments benefit from Solana's execution engine: transactions confirm in under a second and network fees typically run below $0.01, making active trading and frequent position adjustments economically viable for ordinary retail participants.

How Markets Work

Hedgehog uses a pooled liquidity Automated Market Maker (AMM) model. When a market is live, traders buy shares representing a Yes or No position on a future event. Share prices range from $0.01 to $0.99 and reflect the market's implied probability in real time; a Yes share trading at $0.72 implies the crowd assigns a 72% likelihood to that outcome resolving true. If the outcome resolves in a trader's favor, each winning share pays out $1.00 at settlement.

The AMM continuously reprices shares as new liquidity enters or exits, meaning large or one-sided order flow shifts the odds automatically. This removes the need to match individual counterparties and enables instant execution — a meaningful improvement over traditional order-book prediction markets where thin books can trap traders in illiquid positions.

Classic and Versus

Hedgehog offers two distinct product experiences. The Classic interface provides a straightforward binary market interface familiar to anyone who has used Polymarket or similar platforms. The Versus format introduces head-to-head wagering mechanics with adjustable odds and customizable bet sizes, giving participants the feel of a sportsbook alongside the on-chain transparency and permissionlessness of DeFi.

Both interfaces support wallet-based access with no KYC requirements and allow on-chain withdrawals at any time.

No-Loss Prediction Pools

Among Hedgehog's most distinctive features is its no-loss prediction pool mechanic. In these pools, participants do not risk their deposited principal directly. Instead, capital is locked into yield-bearing positions during the pool's duration, and only the interest that accrues over that period becomes the stake redistributed at resolution. Winners receive back their principal plus a share of the pooled yield; losers reclaim their principal but forfeit the yield they could have earned.

This design substantially lowers the psychological and financial barrier to participation. Users who are conviction-light can still put a view on record without fearing a total loss, while the platform retains meaningful skin-in-the-game from yield stakes. It also creates an interesting use case for idle stablecoin or SOL positions that would otherwise earn a flat yield with no upside.

Eclipse Integration

Hedgehog's deployment on Eclipse extends the platform's addressable user base into the Ethereum ecosystem without sacrificing the performance properties of the Solana Virtual Machine. Eclipse runs SVM execution on Ethereum settlement, so Hedgehog can offer the same near-zero fees and sub-second finality to users whose assets and identity live on Ethereum mainnet. This cross-ecosystem positioning distinguishes Hedgehog from purely Solana-native competitors and gives the platform a hedge against any single-chain concentration risk.

HHDG Governance Token

The platform issues the HHDG governance token, which serves two primary functions. First, token holders participate in protocol governance decisions including market listing policies, fee structure adjustments, and upgrade approvals. Second, Hedgehog uses HHDG as a liquidity mining incentive, distributing tokens to early liquidity providers who bootstrap market depth across new and existing markets.

The fee structure for trading is a flat 2% on transactions, split between the protocol treasury and liquidity providers. No settlement or withdrawal fees apply beyond standard Solana network costs.

Competitive Positioning

Hedgehog occupies a distinct niche in the prediction market landscape. Polymarket, currently the dominant platform by volume, runs on Polygon and restricts market creation to a curated set of questions. Hedgehog's permissionless approach directly addresses that limitation, trading some quality control for greater breadth and creator autonomy. Compared to Solana-native alternatives, Hedgehog differentiates through the no-loss pool mechanic, its dual-chain presence on Eclipse, and its open developer resources — including a public GitHub and documentation targeting DeFi developers who want to build prediction market dApps on top of the protocol.

Status and Traction

Hedgehog Markets is live on Solana mainnet. The on-chain program (Yb4spZYFpgad4pDvV1mdU7pFU9vQWNeDS4degy7eR1u) is active. The platform has accumulated meaningful early trading volume since its V1 launch, and has iterated steadily from an early testnet phase to a multi-chain live product with two distinct product formats, a governance token, and an open developer ecosystem.

For Solana users looking for on-chain prediction markets beyond curated top-tier events, Hedgehog Markets represents the most feature-complete permissionless option on the network.
