What Is Synthetix and What Does It Do?

Synthetix is an open-source, permissionless protocol which allows users to create and trade synthetic assets known as "synths" on the Ethereum blockchain. It provides a means of obtaining exposure to the price of real-world assets such as fiat currencies, commodities, and indexes without having to hold the underlying assets. Although originally developed under the name Havven in 2017 to issue stable coins backed by collateral, the project re-branded to Synthetix in 2018 to support a wide variety of synthetic derivative products. The development of the Synthetix protocol is led by several decentralized autonomous organizations (DAOs): The grants council, The ambassador council, The treasury council, and the spartan council.

What is the history of Synthetix and its key milestones?

2017

Havven Founded

Kain Warwick developed Havven as an issuer of collateral-backed stablecoins, specifically to exploit arbitrage opportunities created by price differences between exchanges.

2018

Rebrand to Synthetix

After pivoting from issuing stablecoins to creating a platform for synthetic assets, the company conducted an initial coin offering (ICO) which resulted in $30 million being raised and 60 million HAV / SNX tokens sold to investors.

2019

Additional Funding

In addition to raising funds for further expansion of the capability of the synthetic assets platform, Synthetix also received $3.9 million from Framework Ventures to enable the development of new synthetic assets.

2020

DAO Governance Transition

The Australian non-profit organization established to manage the operations of the Synthetix Foundation has dissolved, and the company has replaced it with the establishment of the spartan council, grants council, ambassador council, and treasury council.

2024

Ethereum Mainnet Perps

The company will be launching the first Ethereum MainNet-settled Continuous Order Book (CLOB) perpetuals exchange utilizing a hybrid architecture.

How Does Synthetix Compare to Competitors?

vs dYdX

Synthetix is better suited to offer synthetic RWAs and pooled collateral while dYdX offers order book perps with deeper liquidity for crypto pairs, and thus, more traditional asset exposure

Synthetix for real world asset synths, dYdX for professional crypto derivative trading.

vs GMX

Both use pooled collateral but GMX is focused exclusively on crypto perps while Synthetix offers broader coverage for fiat, commodities etc., and higher leverage

GMX for high leverage crypto perps, Synthetix for diversified asset exposure.

vs Perpetual Protocol

Synthetix provides infinite liquidity via peer-to-contract model vs Perpetual’s vamm. Synthetix also offers broader coverage beyond only crypto perps.

Synthetix for comprehensive synth trading, Perpetual for simplified perp trading.

vs Mirror Protocol (Terra)

Both offer synthetic stocks / ETFs but Synthetix uses SNX collateral on ethereum vs mirror’s mAssets on Terra. Synthetix is more active post terra collapse.

Synthetix is a more reliable synthetic asset platform.

What are the strengths and limitations of Synthetix?

Pros

  • Infinite liquidity model – peer-to-contract eliminates slippage & counterparty risk
  • Broad asset coverage – real world assets like stocks, commodities, forex on-chain.
  • Pooled collateral efficiency – single SNX pool backs all synths seamlessly
  • Ethereum mainnet is the safest settlement layer in DeFi.
  • All users have crypto-nativity to enter into all global marketplaces.
  • The SNX token holder controls the development of the protocol through active governance.
  • Perpetuals innovations: Ultra-low latency matching engine available on mainnet.

Cons

  • Collateral is required to be extremely high, 400-750%, which results in capital inefficiency.
  • An oracle is needed to provide accurate pricing, which is a single point of failure.
  • Ethereum gas fees are still present when using the mainnet to transact.
  • Risks of liquidation exist due to the volatility of collateral used to stake SNX.
  • Compared to perps-only platforms, Synthetix offers limited leverage.
  • The mechanics of Synthetix are complex; there is a significant learning curve involved with both minting and staking synths.
  • Market volatility can cause imbalances in the debt pool, especially during extreme market conditions.

Who Is Synthetix Best For?

Best For

  • DeFi traders seeking real-world asset exposure — A user has the option to gain borderless access to stock, commodity, forex and other asset types from within the crypto ecosystem.
  • SNX yield farmers — A user has the ability to earn trading fees while providing protocol collateral.
  • Institutions hedging crypto exposure — Synths offer inverse synth and traditional asset options for portfolio diversification.
  • Global investors in restricted markets — A user has the option to access assets globally without the need of traditional financial institutions as an intermediary.
  • Ethereum DeFi composability users — Synths can integrate with lending and yield generating protocols natively.

Not Suitable For

  • High-frequency scalpers — Fees and latency offered by Synthetix are better suited to dYdX or a centralized exchange.
  • Low capital retail traders — High collateral requirements result in small position being capital inefficient. It would be more capital efficient to use a spot DEX.
  • Risk-averse conservative investors — The risks associated with oracle data and smart contracts exceed simply holding the asset. It may be better to consider a stablecoin yield alternative.
  • Users needing 50x+ leverage — The conservative nature of the collateral model reduces leverage. It may be more beneficial to use GMX or high-leverage perpetuals alternatives.

What Are Common Questions About Synthetix?

Synthetix is a decentralized protocol running on the Ethereum and Optimism networks to create and trade synthetic assets called "synths" that track the value of a wide range of real-world assets such as fiat currencies, cryptocurrencies, commodities, equities etc. Synths are collateralized by staked SNX tokens in a pooled collateral model.

When trading Synths, users do so peer-to-contract with each other via smart contracts. This allows users to convert directly between assets without a counterparty or liquidity pool. As a result, users experience no slippage and unlimited liquidity at the current oracle price.

Text 53. SNX is the native cryptocurrency that will be used as collateral to create a new Synth. To earn fees from trading activities (0.30% per trade), stakers lock SNX so that it can serve as collateral for the system and to earn rewards based on the debt pool.

Text 54. Some of the key risks are: the possibility of a smart contract failure; an oracle failure; the possibility that a staker may be liquidated when the collateral ratio falls below 500%; and a significant movement in the price of the underlying asset impacting the value of the synthetic asset.

Text 55. Yes, the entire protocol is permissionless and there are no costs associated with using it on the mainnet with real funds. It has testnets which allow you to do testing and integration testing in a risk-free environment.

Text 56. In contrast to other Automated Market Maker (AMM) DEXs, which require a separate liquidity pool for each pair, Synthetix utilizes pooled SNX collateral for peer-to-peer, peer-to-contract trading. Therefore, it offers unlimited liquidity between any two synthetic assets without having to rely on traditional order books.

Text 57. Since Synthetix is a non-custodial protocol, users retain complete control over their funds through their own wallet. While the audited smart contracts on Ethereum mainnet offer high levels of security, smart contract risks still exist.

Text 58. Settlement is performed on Ethereum mainnet while low-cost transactions occur on Optimism L2. Additionally, Perps trading is offered on mainnet with an ultra-low-latency matching engine.

Is Synthetix Worth It?

Text 59. Synthetix is a pioneer in decentralized synthetic assets and Perpetuals trading, allowing users to utilize peer-to-peer, peer-to-contract trading liquidity without relying on counterparties. The protocols' pooled collateral model resolves one of the fundamental DeFi liquidity problems but introduces a higher level of smart contract and oracle risks characteristic of all complex derivatives platforms.

Recommended For

  • Text 60. DeFi experienced traders who want to gain exposure to real world assets without having to undergo a Know Your Customer (KYC) process.
  • Text 61. SNX stakers who are willing to stake at a 500% or greater collateral ratio.
  • Text 62. Developers creating derivatives user interfaces and Perps trading frontends.
  • Text 63. Crypto-native investors that wish to diversify their synthetic exposures.

!
Use With Caution

  • Text 64. Users that have little to no experience with staking, liquidations, etc. — High Learning Curve.
  • Text 65. Risk-adverse traders — Smart Contract and Oracle Risks Remain. Beginning of Text
  • Entities requiring regulatory compliance and audited custody solutions

Not Recommended For

  • Individual consumers who are looking for a simple spot trading option – too complex
  • Conservative investors who do not want to take on the volatility and associated smart contract risk of DeFi
  • Consumers that want CEX style options such as leverage but do not have collateral to stake
Expert's Conclusion

Synthetix is best suited for experienced DeFi users that trade synths and perps; however, they need to be knowledgeable about risk management and understand how the protocol works.

What do expert reviews and research say about Synthetix?

Key Findings

Synthetix was one of the first decentralized exchanges to develop synthetic assets and peer to contract trading on the Ethereum and Optimism blockchains, allowing consumers to gain access to over 100 real world assets through the use of SNX collateralized Synths. The company continues to actively develop new products including Perps V2/V3 and has introduced perpetuals to the mainnet blockchain using a low latency matching engine. Although there is an increasing amount of competition in this space, Synthetix is still one of the leading decentralized exchanges when it comes to DeFi derivatives.

Data Quality

Good - comprehensive protocol documentation and on-chain data available. Limited customer support/review data as decentralized protocol. No centralized pricing model.

Risk Factors

!
Risk related to vulnerabilities in smart contracts and manipulation of oracles used to determine the value of underlying assets
!
Risk of having your staked collateral liquidated if your collateral ratio drops below the minimum required by the protocol
!
Significant competitive pressure from newer decentralized perpetual exchanges (GMX, Gains Network)
!
Uncertainty related to regulation of synthetic reference to real world assets
