The Sonic blockchain is a Layer-1 EVM-compatible blockchain that stands out because of its speed and a unique feature called Fee Monetization (FeeM). Sonic processes over 400,000 transactions per second (TPS) with sub-second confirmation times, making it much faster than many other EVM blockchains. FeeM is a new economic mechanism where developers earn 90% of the fees from apps they build, as long as those apps increase activity on the network.

Shadow Exchange is a decentralized exchange (DEX) built natively on the Sonic blockchain. It uses an order-style concentrated liquidity approach, which focuses liquidity in specific price ranges to make trading more efficient. Shadow Exchange is designed to enhance users’ trading experience by providing optimized liquidity management, reduced slippage, and an efficient trading environment.

What is Shadow Exchange?

Shadow Exchange is a decentralized exchange (DEX) built natively on the Sonic blockchain, launched in 2024 by a developer known as 24dollars. It’s tailored for crypto beginners and intermediate users, offering a platform to swap tokens, provide liquidity, and earn rewards on the Sonic blockchain. Unlike typical exchanges, Shadow Exchange uses Sonic’s high-speed network to process trades in sub-seconds with low costs. It’s similar to Uniswap v3/v4, focusing on concentrated liquidity, but optimized for Sonic’s high throughput and low costs, pooling liquidity in specific price ranges to reduce slippage for traders and boost provider returns.

Key Features of Sonic Exchange

• x(3,3) Incentives: This reward system builds on the older ve(3,3) model. It lets users earn tokens by staking and voting on liquidity pools, without forcing long lockups. It’s flexible and encourages active participation.
• xShadow: A special token you get by converting SHADOW at a 1:1 ratio. Staking xShadow lets you earn 100% of protocol fees, voting rewards, and penalties from early exits. It’s the core of governance and reward distribution.
• PvP Rebase: This is a unique twist to protect stakers, reward loyalty, and keep the system stable. If someone exits xShadow early, they lose up to 50% of their tokens, which then go to the remaining stakers.
• Concentrated Liquidity: Instead of spreading liquidity across all prices, Shadow focuses it on specific ranges. This reduces slippage for traders and boosts returns for liquidity providers.
• Competitive Farming: Liquidity providers can earn high annual percentage yields (APYs) by staking in active pools. Some pools offer over 70% APY, making it attractive for yield seekers.
• Active Staking: To earn rewards like fees or rebases, you need to stake xShadow and vote. Passive holding isn’t enough—active engagement is key.
• Dynamic Fees: Fees adjust based on market conditions. High-volume pairs might have higher fees for providers, while new pairs get lower fees with more token rewards to attract liquidity.
• Liquid Staking: Through x(3,3), a liquid version of xShadow, you can stake and still trade your assets. It starts at a 1:1 ratio with xShadow but grows as rewards pile up, offering flexibility without skipping penalties.
• Feeshare: Sonic’s Fee Monetization (FeeM) returns 90% of gas fees to users or developers. Shadow uses this to keep transaction costs low, enhancing the experience for traders and providers

Core Concepts of Shadow Exchange

x(3,3)

x(3,3) is a core incentive mechanism powering Shadow Exchange on the Sonic blockchain, an evolution of the ve(3,3) model pioneered by Solidly. It allows users to stake tokens and vote on liquidity pools to direct token emissions, earning rewards proportional to their stake and voting power at the end of each epoch. Unlike ve(3,3), which often requires locking tokens for months or years to maximize rewards, x(3,3) removes mandatory long-term commitments, offering flexibility for short-term participation. This design suits active traders and liquidity providers who prefer adaptability over rigid lockups.

The process works through staking xShadow or $x33, the platform’s governance tokens. Users stake tokens and vote on liquidity pools to direct emissions, earning rewards per epoch without mandatory long-term locks. The more xShadow or $x33 staked and directed toward a pool, the higher its emission share, incentivizing strategic voting to boost returns. Rewards come from protocol fees and emission tokens, with the exact payout tied to the pool’s performance and total votes cast. This setup contrasts ve(3,3)’s focus on long-term holders by rewarding active engagement over passive locking.

xShadow

xShadow, a non-transferable staking and governance token on Shadow Exchange, is the backbone of Shadow Exchange’s reward and governance system. It’s earned through SHADOW conversion or staking emissions, not purchasable on open markets, ensuring rewards go to active participants. It locks SHADOW for a user-selected vesting period of 15 to 180 days, enabling access to protocol fees, voting incentives, and rebase rewards. Users can cancel within 14 days for a full refund (1:1 SHADOW return). Exiting after 14 days but before 180 days incurs a 50% penalty, with the forfeited SHADOW redistributed to remaining stakers via PvP rebase.

Utility of xShadow

• Protocol Fees: Stakers earn 100% of fees generated from trades, proportional to their xShadow stake.
• Voting Incentives: It is used to vote on pool gauges in the x(3,3) system, directing emissions to preferred liquidity pools, with rewards tied to voting power.
• Governance and Liquid Staking: It influences platform decisions and supports conversion to $x33 for liquid staking, maintaining reward eligibility while enabling flexibility.

Legacy Liquidity

Legacy Liquidity is Shadow Exchange’s traditional liquidity framework, drawing from Uniswap v2’s design to support token swaps and liquidity provision on the Sonic blockchain. It operates through two pool types: volatile and stable. Volatile pairs match tokens by equal dollar value—e.g., $50 of Token A with $50 of Token B—suited for assets with fluctuating prices like ETH or memecoins. Stable pairs, tailored for correlated assets like stablecoins (e.g., USDC-USDT), use a modified curve to minimize slippage and maintain price parity, which is ideal for low-volatility swaps.

These pools rely on the constant product formula (x y = k), where x and y are the quantities of each token, and k is a constant. Exchange rates and slippage adjust dynamically as trades alter the pool’s balance—e.g., buying Token A reduces its supply, raising its price relative to Token B. Arbitrage bots monitor these shifts, trading against external market prices to rebalance pools and keep rates consistent, a process facilitated by Sonic’s sub-second finality and low fees ($0.001 average).

Concentrated Liquidity

Concentrated Liquidity is the cornerstone of Shadow Exchange’s trading and liquidity provision system, built on the Ramses V3 Core, an adaptation of Uniswap V3, and tailored for the Sonic blockchain’s high-performance environment. This model departs from the broad coverage of Legacy Liquidity by allowing providers to allocate tokens to specific price ranges—e.g., ETH-USDC between $2,000 and $2,500—instead of the full spectrum (0 to infinity). This targeted approach maximizes capital efficiency, ensuring liquidity is only active where trading demand exists, reducing slippage for traders, and boosting fee returns for providers.

The mechanism works by letting liquidity providers define upper and lower price bounds for their positions. Within these ranges, the pool operates under a modified constant product formula (x y = k), but only for the specified segment. For example, if ETH’s price is $2,300, a provider’s $2,000-$2,500 range is fully utilized, earning 95% of swap fees (typically 0.3% per trade), while a $1,500-$1,900 range earns nothing until the price shifts. Positions are minted as non-fungible tokens (NFTs), tracked individually by the Ramses V3 accounting system, enabling precise management.

Architecture of Shadow Exchange

Liquidity Models

The system supports two liquidity frameworks:

• Legacy Liquidity: Based on Uniswap v2, it uses constant product pools (x y = k) for volatile and stable pairs. Volatile pairs balance tokens by equal dollar value, while stable pairs use tighter curves for correlated assets (e.g., USDC-USDT). Liquidity spans all prices, managed by arbitrage bots, with 95% of swap fees (typically 0.3%) distributed to providers.
• Concentrated Liquidity: Built on Ramses V3 Core (Uniswap V3 derivative), it focuses liquidity in user-defined price ranges (e.g., ETH-USDC $2,000-$2,500). Positions are tracked as NFTs, enabling rapid adjustments via Sonic’s speed. Fees accrue only within active ranges, maximizing capital efficiency and reducing slippage, with 95% allocated to providers.

Incentive and Reward System

The x(3,3) mechanism drives token emissions, replacing ve(3,3)’s long lockups with flexible staking and voting. Users stake xShadow (SHADOW at 1:1, 15-180 day vesting) or $x33 (liquid staking variant) to vote on pool gauges, directing emissions per epoch (weekly reset, Thursday 00:00 UTC). Rewards include:

• Protocol Fees: 100% of trading fees to xShadow stakers, proportional to stake.
• Voting Incentives: Emissions tied to voting power, boosting active pools.
• PvP Rebase: Early xShadow exits (post-14 days, pre-180 days) incur a 50% penalty, redistributed to remaining stakers post-epoch, stabilizing the system.

Smart Contract Infrastructure

Shadow Exchange operates via audited smart contracts, forked from Solidly and enhanced by Ramses V3 Core. Key functions include:

• Pool Management: Handles Legacy and Concentrated Liquidity pools, tracking balances and fees.
• Fee Distribution: Allocates 95% of swap fees to LPs, and 5% to operations, with FeeM refunding 90% of gas costs.
• Governance: xShadow voting adjusts emissions and platform parameters, executed on-chain.
• Rebase Logic: Manages penalty redistribution, ensuring anti-dilution for long-term stakers.

Sonic Integration

Sonic’s infrastructure—sub-second block times, high TPS, and low-cost transactions—underpins the architecture. FeeM returns 90% of gas fees to users or developers, enabling high-frequency trading and position updates without cost barriers. This supports Concentrated Liquidity’s rapid adjustments and Legacy Liquidity’s arbitrage efficiency, driving volume.

Design Principles

Built on Solidly’s ve(3,3) and Ramses’ V3 enhancements, Shadow Exchange balances flexibility (short-term staking) with efficiency (concentrated ranges). Audits ensure security, while Sonic’s speed amplifies performance, making it a scalable DeFi engine for 457+ pools.

Stake for Rewards

Convert $SHADOW to xShadow (1:1) under the “Stake” tab. Pick a vesting period (15-180 days), approve, and lock. Vote on pool gauges via x(3,3) to direct emissions, earning fees, and rebases. Alternatively, swap xShadow for $x33 for liquid staking, maintaining tradability.

Monitor and Manage

Check positions in “My Pools” (LP fees) or “Staking” (xShadow rewards). Claim fees or emissions post-epoch (Thursday 00:00 UTC). For xShadow, exit post-180 days for full redemption or face a 50% penalty pre-180 days (after a 14-day grace).

Tokenomics

$SHADOW, the utility token of Shadow Exchange has a maximum supply of 10 million tokens. Its initial distribution includes: Contributors (750,000), Presales (750,000), Liquidity Incentives (3,500,000), Airdrop (500,000), Team (1,500,000, vesting over 2 years), and Treasury (3,000,000). Emissions began at 50,000 $SHADOW weekly, decaying by 1% per week, incentivizing early participation.

Utility and Governance Features

$SHADOW serves multiple roles:

• Fee Generation: Trading fees (e.g., 0.3% per swap, 95% to LPs) fund the ecosystem, with xShadow stakers earning 100% of protocol fees post-epoch (Thursday 00:00 UTC).
• Staking and Rewards: Convert $SHADOW to xShadow (1:1, 15-180 day vesting) to stake and vote in the x(3,3) system, directing emissions to pools. Rewards include fees, voting incentives, and PvP rebase (50% penalty from early exits, redistributed to stakers).
• Governance: xShadow holders vote on pool gauges and platform parameters, influencing emission allocation and strategic decisions. Liquid staking via $x33 retains voting power while enabling tradability.
• Liquidity Incentives: 3.5 million $SHADOW are allocated for liquidity pools, supporting competitive farming (APYs >70%) and bootstrapping trading volume.

Emission and Vesting Mechanics

Emissions decay weekly by 1% from an initial 50,000 $SHADOW, balancing inflation and rewarding sustainability. Team tokens vest over 2 years, aligning long-term interests, while xShadow’s 15-180 day vesting (14-day penalty-free exit, 50% penalty pre-180 days) encourages commitment. The 10 million cap ensures scarcity as adoption grows, with current circulation reflecting early-stage deployment.
