Introduction
Synthetix is an Ethereum-based decentralized protocol for issuing synthetic assets. These synthetic assets (Synths) are collateralized by the Synthetix Network Token (SNX), enabling users to mint Synths by locking SNX in smart contracts.
Key Features
- Collateralized Synths: All Synths are backed by SNX at an 800% collateralization ratio
- Peer-to-Contract Trading: Eliminates need for counterparties through smart contract execution
- Diverse Asset Classes: Supports synthetic fiat currencies, cryptocurrencies (long/short), and commodities
SNX Staking Mechanism
How SNX Backs Synths
- SNX holders use Mintr (a dApp) to stake SNX as collateral
- Current 800% collateral ratio may be adjusted via community governance
- Stakers incur debt when creating Synths, which must be repaid to unlock SNX
Benefits of Holding SNX
Trading Rewards:
- 0.1%-1% fee on Synth exchanges (typically 0.3%)
- Distributed weekly to SNX stakers proportional to their debt share
Inflationary Rewards:
- SNX supply increases from 100M (2019) to 260M (2023)
- 2.5% annual inflation post-2023
- Rewards distributed weekly to compliant stakers
Maintaining Collateralization
Stakers are incentivized to maintain:
- Minimum 750% collateral ratio
- Ability to adjust ratio by minting/burning Synths
Synth Pegging Mechanisms
Three methods maintain Synth price stability:
- Arbitrage Opportunities: Stakers profit by buying undervalued Synths
- Uniswap Liquidity Pools: sETH/ETH pool rewards liquidity providers
- SNX Auctions: Discounted SNX auctions help stabilize prices

System Architecture
Synth Minting Process
- Smart contract verifies collateralization ratio (<800%)
- Debt added to registry in sUSD
- New Synths minted and transferred to user
Exchange Workflow
- Source Synth burned (e.g., sUSD)
- Exchange rate calculated via oracle
- 0.3% fee sent to rewards pool
- Target Synth (e.g., sBTC) minted
Debt Pool Dynamics
- Debt fluctuates based on Synth exchange rates
- "Accumulated debt delta" tracks proportional shares
- Formula:
New Debt Ratio = (Existing Debt + New Debt) / (Total Debt + New Debt)
Risk Management
Current Risks
- Debt Fluctuation: Synth price changes affect repayment amounts
- Crypto Correlation: SNX price volatility impacts collateralization
- Partial Centralization: Proxy contracts enable upgrades
Mitigation Strategies
- Decentralized Oracles: Partnership with Chainlink
- Community Governance: SIP (Synthetix Improvement Proposals)
- Progressive Decentralization: Phased removal of centralized components
Future Developments
- Expanded Synths: Stocks, indices, leveraged assets
- Synthetic Futures: Autonomous market maker mechanism
- Advanced Order Types: Limit orders, stop losses
FAQ
Why stake SNX?
Stakers earn trading fees and inflationary rewards while supporting network liquidity.
How does debt work in Synthetix?
All stakers share system debt proportional to their Synth minting. Debt fluctuates with Synth prices.
What happens if my collateralization drops below 750%?
You won't be able to claim rewards until you restore the ratio by minting/burning Synths.
How are Synth prices maintained?
Through arbitrage, liquidity incentives, and auction mechanisms that correct price deviations.
