Synthetix has introduced an innovative concept in trading synthetic assets, called “synths,” which are collateralized using the Synthetix Network Token (SNX). This system allows for seamless synth conversions through smart contracts, overcoming liquidity and slippage issues commonly faced in decentralized exchanges (DEXs). By delving into the intricate workings of Synthetix as outlined in its January 2023 Litepaper (version 1.6), it becomes clear that this protocol has a significant impact and potential in the rapidly growing world of decentralized finance (DeFi).
The Core Concepts of Synthetix
Synthetix is a decentralized protocol that aims to provide liquidity in the digital asset space. It is built on the Ethereum blockchain, leveraging its security and decentralized nature. The protocol enables the creation and exchange of synthetic assets, which are digital representations of various asset classes. These synths are collateralized by Synthetix Network Tokens (SNX), ensuring a stable and trustworthy system for users to engage in asset trading without the need for traditional financial intermediaries.
Ethereum serves as the backbone of Synthetix, providing the necessary infrastructure for decentralized applications (dApps) and smart contracts, which are essential for the protocol’s functionality. The integration of Optimistic Ethereum, a layer two scaling solution, further enhances the protocol by offering faster transaction speeds and lower fees. This integration allows Synthetix to handle a higher throughput of transactions, which is crucial for maintaining efficiency and scalability in the DeFi ecosystem. Together, these platforms create a robust and efficient environment for Synthetix to operate and thrive.
While Synthetix champions decentralization, it strategically employs certain centralized elements, such as proxy contracts, to enhance system efficiency and facilitate smooth upgrades. These contracts currently give the engineering team some control, requiring user trust. However, this is a temporary measure. Synthetix aims to progressively eliminate these centralized components, moving towards a fully decentralized architecture in line with its long-term vision. This approach emphasizes Synthetix’s commitment to maintaining a robust and adaptable platform during its growth phase.
Synthetix Network Token (SNX) and Synthetics
The Synthetix system utilizes its native token, SNX, as the primary collateral for backing synthetic assets. SNX holders can participate in the Synthetix network by staking their tokens, which enables the issuance of synths. This staking mechanism ensures that all synthetic assets in the network have tangible backing, maintaining the system’s integrity and stability.
The process of minting synths begins with SNX holders locking their tokens as collateral. This is facilitated by the Synthetix Staking application, which seamlessly integrates with the protocol’s smart contracts. Once SNX is staked, users can mint various synths, which are directly tied to the value of their collateralized SNX.
When users mint synths, they incur a “debt” corresponding to the value of the minted synths. This debt fluctuates based on the network’s exchange rates and the supply of synths. As market conditions change, so does the debt level, with SNX stakers bearing the risk and rewards of these shifts. This dynamic debt system is central to the Synthetix protocol, underpinning its unique approach to decentralized finance.
Synthetix has expanded its collateral base beyond the native SNX token. By including well-known cryptocurrencies like Ethereum (ETH), Liquity USD (LUSD), and Dai (DAI) through loans and wrappers, the platform offers users a variety of collateral options while fortifying the Synthetix network against market volatility. Comprehensive details on these additional collateral types can be found in the Synthetix Improvement Proposals (SIPs) for those interested in diving deeper.
Incentives for SNX Stakers
Exchange Rewards
SNX stakers receive rewards through exchange fees generated from trades on platforms like Kwenta Perpetual Futures. Each trade contributes a fee to a collective pool, from which SNX stakers can claim their share on a weekly basis. This mechanism creates a continuous incentive for users to stake their SNX tokens.
SNX Staking Rewards
In addition to exchange rewards, SNX stakers also receive staking rewards as part of the protocol’s inflationary monetary policy. These rewards are designed to encourage consistent staking and participation in the network.
Inflationary Monetary Policy
Synthetix’s inflationary policy is designed to maintain a stable staking ratio, targeted at around 85%. The policy adjusts the rate of inflation based on this target, increasing or decreasing it to incentivize stakers to maintain the desired ratio. This approach ensures a balanced and robust economic model for the Synthetix ecosystem.
Collateralization Ratio (C-Ratio) Management
Maintaining the Collateralization Ratio (C-Ratio) is crucial for network assurance in Synthetix. This ratio, a key benchmark within the protocol, determines how well synths are backed by SNX collateral. A robust C-Ratio instills confidence in the platform, safeguarding it against significant price fluctuations and ensuring operational integrity.
A consistent C-Ratio is fundamental for the equilibrium of the Synthetix ecosystem. It guarantees the system’s solvency and the validity of its synthetic assets. Fluctuations in the C-Ratio can lead to under-collateralization, which affects network confidence and functionality. Therefore, managing the C-Ratio is crucial not only for individual participants but also for the overall health and dependability of the Synthetix framework.
The value of SNX plays a crucial role in the collateralization process within Synthetix. As the market value of SNX rises, the protocol intelligently adjusts by unlocking a portion of the staker’s collateral. For example, if an individual’s SNX collateral doubles in value, half of it automatically becomes unlocked. This mechanism aligns with market dynamics and allows stakers to re-stake or use their SNX, reflecting the platform’s responsiveness to market changes.
Liquidation Mechanisms
Liquidation serves as a crucial mechanism in Synthetix to maintain network health. It incentivizes stakers to maintain a healthy C-Ratio, as failing to do so results in liquidation with penalties. This process benefits individual stakeholders by encouraging responsible participation and enhancing the overall network’s C-Ratio. Furthermore, it addresses issues with inactive staking wallets, ensuring they do not negatively impact the network’s health.
When a staker’s C-Ratio falls below the liquidation threshold, they are flagged for liquidation and given a period of 8 hours to rectify their C-Ratio. Failure to do so leads to liquidation, which involves penalties. This process design is fair yet strict, enforcing participants’ discipline and safeguarding the network’s stability.
Synthetix employs a remarkable debt management strategy, particularly when users burn synths. This action triggers a recalibration of the individual’s debt shares within the pool. Such adjustments are crucial for maintaining equity among network participants, reflecting Synthetix’s commitment to a balanced and sustainable economic environment. It highlights the platform’s advanced and thoughtful approach to managing its internal economic system, ensuring fairness and stability within its ecosystem.
Trading on Synthetix: Advantages and Mechanisms
Synthetix offers a unique trading approach known as peer-to-contract (P2C) trading, which eliminates the need for traditional order books. This model allows trades to be executed directly against the contract, using price feeds provided by oracles. This mechanism offers seamless conversions and enhanced liquidity compared to traditional centralized exchanges and order book-based decentralized exchanges (DEXs).
Synthetix also features decentralized perpetual futures trading through its platform, Synthetix Perps. This platform provides deep liquidity with low fees, allowing users to trade futures contracts on various assets without actually holding them. The margin for these positions is denominated in sUSD, offering a simplified and more stable trading experience.
Synthetix System Architecture
The process of minting synths in the Synthetix system begins with SNX holders locking their tokens as collateral. The protocol’s smart contract verifies that the staker’s Collateralization Ratio is within the required limit. Once verified, the contract issues debt shares proportional to the amount of sUSD minted. The sUSD is then generated and credited to the staker’s wallet, reflecting the new total supply of the synth in the system.
The exchange of synths in Synthetix follows a specific mechanism where the source synth (e.g., sUSD) is burned, reducing its total supply. At the same time, an equivalent value of the destination synth (e.g., sBTC) is minted. This mechanism does not require a counterparty and ensures infinite liquidity for conversions between different synths. This process is key to facilitating smooth and efficient trading within the platform.
Claiming fees and rewards is an entitlement for SNX stakers. The fees accumulated from synth exchanges are collected in sUSD and stored in a fee pool. When stakers claim their fees, they receive a portion based on their debt ratio in the system. Alongside these exchange fees, SNX stakeholders also receive staking rewards distributed in SNX tokens. These rewards are part of the protocol’s incentive structure to encourage continuous participation and staking within the Synthetix ecosystem.
The Role of Oracles in Synthetix
Oracles play a crucial role in Synthetix by providing real-time and accurate market data. They aggregate price information from various external sources, creating a comprehensive and reliable dataset. The oracles feed this aggregated data into the Synthetix system, which then determines the value of synthetic assets, or synths. By using these oracles, Synthetix ensures that all trading activities, collateral valuations, and financial operations within the platform are executed at up-to-date and accurate market prices, maintaining the integrity and reliability of the platform.
Risks and Risk Mitigation Strategies
The Synthetix system, while innovative, faces several risks due to its complex and experimental nature. The main risks include fluctuations in debt levels due to shifts in exchange rates and potential significant price fluctuations in SNX tokens. Additionally, certain aspects of the system currently retain centralized elements, requiring a degree of trust from users.
To mitigate these risks, Synthetix is gradually moving towards decentralization and censorship resistance. This includes securing price feeds through decentralized oracle solutions like Chainlink and implementing a governance system with councils elected by the community. These measures enhance trust, security, and autonomy within the Synthetix ecosystem.
Governance in Synthetix
Governance in Synthetix is a community-driven process overseen by various councils. The most prominent council is the Spartan Council, which is elected by the Synthetix community. This council plays a crucial role in deciding protocol changes and upgrades, ensuring that community members directly impact the direction and development of the protocol. This governance structure reflects Synthetix’s commitment to decentralization, allowing for a democratic and participatory approach to decision-making within the ecosystem.
Synthetix is on a strategic path towards complete decentralization, emphasizing community involvement and censorship resistance. This transition is evident in its adoption of decentralized oracles like Chainlink for accurate price feeds. Additionally, the protocol empowers users through a community-elected Spartan Council responsible for overseeing protocol changes. These initiatives highlight Synthetix’s commitment to fostering a user-centric, decentralized financial ecosystem, demonstrating its alignment with the core principles of the DeFi movement.
