Swap SNX
Across Every
EVM Chain

SNX Swap is a specialized EVM-native decentralized exchange and staking interface purpose-built for the Synthetix (SNX) token ecosystem. It aggregates liquidity from all major EVM DEXes to offer the best SNX swap rates across Ethereum, Optimism, Base and Arbitrum, while also providing a native staking interface for earning sUSD rewards. Prices are pulled live from CoinGecko API for accurate, real-time rate display.

Synthetix is a decentralized liquidity protocol on Ethereum and Optimism that allows the creation of synthetic assets (Synths) — on-chain representations of real-world assets like USD, Bitcoin, gold, and stocks. SNX is the native collateral and governance token. Holders stake SNX to provide collateral backing for the entire Synth ecosystem and earn weekly protocol fee revenue in return. The protocol has processed billions in trading volume and is a cornerstone of the EVM DeFi ecosystem.

The SNX Swap widget defaults to 1000 SNX → ETH with live CoinGecko pricing. To execute: (1) Connect your EVM wallet via the "Connect Wallet" button. (2) The swap interface is pre-loaded with 1000 SNX as the input and ETH as the output — adjust if needed. (3) Review the quoted ETH output, price impact and estimated gas. (4) Set slippage tolerance (0.3% default works for most conditions). (5) Click "Swap Now" and approve in your wallet. The transaction settles on your selected EVM chain.

SNX Swap fetches live SNX and ETH prices directly from the CoinGecko public API (api.coingecko.com/api/v3/coins/markets). CoinGecko aggregates prices from hundreds of exchanges, giving a manipulation-resistant consensus price. Prices auto-refresh every 60 seconds and are displayed in the header ticker, swap widget, and dedicated price display. The live SNX/ETH conversion rate shown in the swap widget is calculated from CoinGecko's real-time USD prices for both tokens.

SNX Swap supports all major EVM wallets: MetaMask (recommended), WalletConnect v2 (200+ wallet apps), Coinbase Wallet, Ledger Live (hardware), Trezor Suite (hardware), Rabby Wallet, Rainbow Wallet, Frame, Phantom (EVM mode), Trust Wallet and any browser extension that injects window.ethereum. Hardware wallets are fully supported for both swaps and staking operations. There is no proprietary wallet — if it works with Ethereum, it works with SNX Swap.

SNX Swap charges a minimal protocol fee of 0.05%–0.1% per swap, among the lowest in the EVM DEX aggregator market. You also pay standard EVM gas fees to the network — on Ethereum mainnet this varies by congestion; on Optimism and Base it is typically under $0.10 per transaction. The total fee breakdown (protocol fee + gas estimate + price impact) is always displayed transparently before you confirm. No hidden fees are ever charged after quote acceptance.

SNX staking means locking your SNX tokens as collateral in the Synthetix protocol. When you stake, the protocol mints sUSD (a synthetic USD stablecoin) proportional to your SNX value, up to the Target Collateralisation Ratio (currently 500%). This sUSD represents your share of the global Synthetix debt pool. In exchange for providing this collateral, you earn a weekly share of all trading fees generated by Synthetix products — paid in sUSD — plus SNX inflationary rewards depending on your chain.

The Collateralisation Ratio (C-Ratio) is the ratio between the value of your staked SNX and the value of sUSD debt you have minted. Synthetix targets 500% C-Ratio, meaning for every $1 of sUSD debt, you must hold $5 in SNX collateral. If SNX price falls and your C-Ratio drops below the target, you cannot claim rewards and may need to burn sUSD to restore it. If it falls below the liquidation threshold (~150%), your position may be liquidated. SNX Swap's dashboard shows your live C-Ratio and alerts when it needs attention.

sUSD (Synthetic USD) is Synthetix's on-chain stablecoin, soft-pegged to the US Dollar. It is minted by SNX stakers as debt when they stake their SNX tokens. sUSD is one of the most liquid synthetic stablecoins in DeFi and can be used across the Synthetix ecosystem to trade synthetic assets, or exchanged for USDC/USDT on major EVM DEXes. SNX stakers receive weekly protocol fee rewards in sUSD, making it both a staking yield token and a functional DeFi stablecoin.

Optimism is Synthetix's primary deployment chain. The majority of Synthetix protocol TVL, trading volume and staking activity occurs on Optimism rather than Ethereum mainnet. Optimism offers dramatically lower gas fees (under $0.10 per transaction vs $5–$50 on mainnet) with the same EVM security model, making frequent staking actions like claiming rewards, adjusting C-Ratio and minting/burning sUSD economically viable for all staker sizes — not just large holders. SNX Swap defaults to Optimism for staking and recommends it for new stakers.

MEV (Maximal Extractable Value) bots monitor the public Ethereum mempool and can detect your pending swap transaction. They insert their own transactions before yours — buying the token you want to buy at a lower price, then selling it to you at a higher price. This is called a sandwich attack. SNX Swap routes all mainnet transactions through private mempool infrastructure (Flashbots-style relays), making your transactions invisible to bots until they confirm. This protects your quoted rate on large SNX swaps where MEV extraction is most profitable.

No. SNX Swap is a fully permissionless, non-custodial protocol. There is no account registration, no email required, no identity verification, and no KYC/AML process. All you need is an EVM-compatible wallet with SNX or ETH balance. The protocol's smart contracts are open to any wallet address without restriction. SNX Swap can never block, freeze or reverse your transactions — the protocol has no admin control over individual user positions or funds.

For most SNX/ETH swaps, 0.3% slippage is optimal — the SNX Swap default. For very large swaps (over $100K), use 0.5% to account for price impact across multiple liquidity pools. For stable pairs or very small swaps, 0.1% is safe. "Auto" mode analyzes pool depth and volatility to set optimal slippage dynamically. Setting slippage too low causes transactions to revert and waste gas; too high means you accept potentially worse execution. On Optimism and Base, lower slippage works reliably due to higher throughput and faster block times.

SNX Swap's routing engine simultaneously queries all major EVM DEX pools including Uniswap v2/v3, Curve, Balancer, Velodrome (on Optimism), SushiSwap, Camelot (Arbitrum) and aggregators like 1inch and Paraswap. The router evaluates thousands of possible paths and order splits, accounting for price impact, gas costs and slippage. It selects the combination that maximizes your net output after all costs. For large SNX orders, it splits across multiple pools to minimize market impact. Quotes refresh every 15 seconds.

Synthetix Synths are on-chain synthetic assets that track the price of real-world assets without requiring you to hold them. Examples include sUSD (US Dollar), sBTC (Bitcoin), sETH (Ethereum), and synthetic stocks. SNX stakers are the collateral backing all Synths — their staked SNX allows the protocol to mint Synths on demand. SNX Swap enables you to acquire SNX to stake and back the Synth ecosystem, and also to swap sUSD and other Synths back to standard ERC-20 tokens when needed.

Synthetix distributes staking rewards in weekly epochs. At the end of each epoch (Thursday UTC), two types of rewards are claimable: (1) sUSD fee rewards — a proportional share of all trading fees generated by Synthetix perps, spot synths and other products that week; (2) SNX inflationary rewards — new SNX emitted by the protocol distributed to active stakers. To claim rewards, your C-Ratio must be at or above the target. Unclaimed rewards expire after two weeks if not collected. SNX Swap shows your claimable rewards and sends reminders via the dashboard.

Yes. If your C-Ratio falls below Synthetix's liquidation threshold (approximately 150%) and remains there after a liquidation delay period, other users can liquidate your staked SNX position. Liquidators repay a portion of your sUSD debt and receive your SNX at a discount as a bonus. To prevent liquidation: monitor your C-Ratio regularly in the SNX Swap staking dashboard, burn sUSD to reduce debt when SNX price falls, or add more SNX collateral. Maintaining a C-Ratio well above the target (e.g., 600%+) provides a significant safety buffer during volatile market conditions.

As a Synthetix staker, you take on a share of the global debt pool — the total outstanding value of all Synths. If synthetic asset prices rise (e.g., sETH rallies because ETH price increases), the total debt pool grows, and your proportional share of debt increases even if you hold no sETH. This means your effective cost to close your position can rise with the market. The debt pool risk is unique to Synthetix and is why staking APY can be high — you're compensated for bearing this systemic risk. Active stakers hedge by mirroring the debt pool composition with their own Synth holdings.

To unstake SNX, you must first burn all the sUSD debt associated with your staked position. Once your debt is zero, your SNX unlocks and can be transferred or sold. The process in SNX Swap's staking interface: (1) Navigate to the Staking dashboard → Burn tab. (2) Enter the amount of sUSD to burn (must equal your full outstanding debt to fully unlock). (3) Confirm the burn transaction. (4) After debt is cleared, click "Unstake" to free your SNX. If you don't have enough sUSD, you can swap for it first using the Swap module.

Yes — SNX Swap is fully responsive and works on all mobile browsers. For the best experience, open snx-swap.com inside a mobile wallet's built-in browser: MetaMask mobile, Coinbase Wallet browser, Rainbow, or Trust Wallet. These automatically inject your wallet for one-tap transaction signing. Alternatively, any mobile browser works with WalletConnect — scan the QR code with your wallet app. The full swap and staking interfaces are available and optimized for touch on screens from 320px wide.

SNX Swap can route SNX to any ERC-20 token with liquidity on any integrated EVM DEX. The most popular pairs are SNX/ETH, SNX/USDC, SNX/USDT, SNX/WBTC, SNX/DAI, and SNX/sUSD. You can also swap SNX for OP (on Optimism), ARB (on Arbitrum), or any other chain-native token. The default widget is pre-configured for 1000 SNX → ETH, reflecting the most common trade. Use the token selector to choose any destination token on your selected EVM chain.

Synthetix Perps (Perpetual Futures) are on-chain perpetual contracts built on top of the Synthetix debt pool. Traders use sUSD as margin to trade leveraged long or short positions on assets like BTC, ETH, SOL and hundreds of others. Every trade generates a fee paid in sUSD — and a portion of these fees flows into the weekly SNX staker reward pool. As Synthetix Perps volume grows (often reaching $500M+ weekly), staker fee rewards grow proportionally. This makes SNX staking yield naturally correlated with overall DeFi trading activity.

SNX Swap's smart contracts have undergone independent security audits by leading EVM security firms. Full audit reports are available in the documentation at snx-swap.com/docs. An active bug bounty program rewards responsible disclosure of vulnerabilities. The protocol is non-custodial — no admin key can access or move user funds. Any protocol upgrade goes through on-chain governance with a time-lock delay, giving the community time to review changes before they take effect. SNX Swap also leverages the security of audited underlying DEXes (Uniswap, Curve etc.) for swap execution.

SNX exists natively on both Ethereum mainnet and Optimism as an ERC-20 token. They are bridged versions of the same asset — you can move SNX between chains using the official Optimism bridge. For trading (swapping), SNX liquidity exists on both chains, but Optimism offers much lower gas fees. For staking, Optimism is strongly preferred: lower fees make frequent reward claiming economical, and most Synthetix protocol activity (Perps volume, Synth trading) happens on Optimism, generating higher fee rewards for Optimism stakers. SNX Swap supports seamless switching between both chains.

Each EVM chain uses ETH as the gas token: Ethereum mainnet (ETH), Optimism (ETH), Base (ETH), Arbitrum (ETH). Polygon uses MATIC, Avalanche uses AVAX, BNB Chain uses BNB. For SNX Swap on the primary chains (Ethereum and Optimism), you always need ETH in your wallet to pay gas. On L2s (Optimism, Base, Arbitrum), gas costs are typically under $0.10 per transaction, making even small SNX trades and frequent staking actions economically practical.

Yes. SNX Swap supports gasless limit orders powered by the CoW Protocol (Coincidence of Wants) order flow system. You set a target price for your SNX/ETH swap, and the order fills automatically when the market reaches your price — without paying gas upfront. Limit orders on SNX Swap are off-chain signed orders that cost no gas unless they execute. You can cancel them at any time before execution with a single on-chain transaction. Limit orders are especially useful for large SNX swaps where you want to avoid market impact from immediate market execution.

SNX Swap aggregates liquidity from multiple sources rather than operating its own AMM pools. The primary SNX liquidity exists on: Uniswap v3 (SNX/ETH, SNX/USDC on Ethereum and Optimism), Velodrome (SNX/USDC, SNX/sUSD on Optimism), Curve (sUSD pools on Ethereum), and Balancer (SNX/ETH weighted pools). SNX Swap's router queries all these simultaneously and routes your trade through the optimal path. You can also provide liquidity directly to these pools through SNX Swap's "Pool" interface and earn their respective LP fees.

Yes. SNX Swap operates a permissionless on-chain referral system. Your referral link is derived from your EVM wallet address — no registration needed. When a user you refer executes a swap, you earn a portion of the protocol fee paid directly in ETH or USDC to your wallet. Referred users receive a first-swap fee discount. All referral earnings accumulate on-chain and can be claimed at any time. High-volume referrers can apply for the SNX Swap Partner program via the governance forum for enhanced rates and co-marketing support.

Using SNX Swap vs a centralized exchange (CEX): Custody — CEX holds your SNX; SNX Swap never does. Privacy — CEX requires ID verification; SNX Swap requires no KYC. Settlement — CEX trades are off-chain database entries; SNX Swap trades settle on-chain permanently. Rate — SNX Swap aggregates all DEX liquidity for best price; CEX order books vary. Staking — SNX Swap provides integrated EVM staking; CEX staking (if offered) is custodial. The main advantage of a CEX is fiat on/off ramp access. For any on-chain DeFi interaction with SNX, SNX Swap is the more powerful and lower-risk option.

Synthetix (SNX) has a total supply of 308.07 million tokens. The supply was initially fixed but later adjusted via governance to include inflationary emissions distributed to stakers as rewards. The inflation schedule has been progressively reduced through multiple governance votes. New SNX emitted as staking rewards is a key incentive for stakers to maintain their C-Ratio and actively participate in the protocol. All current supply metrics are visible in real time on CoinGecko and are reflected in the SNX price data shown on SNX Swap.

Yes. Your full transaction history — swaps, staking actions, reward claims and burns — is available in the SNX Swap account dashboard after connecting your wallet. Every transaction is also permanently on-chain and viewable on Etherscan (for Ethereum mainnet), Optimistic Etherscan (for Optimism), Basescan (for Base) or Arbiscan (for Arbitrum) by searching your wallet address. On-chain transaction data is public, permanent and cannot be altered or deleted by anyone.

Nothing. Your SNX remains in your wallet at all times — SNX Swap never takes custody of your tokens. The smart contracts on Ethereum and Optimism are immutable and will continue to function regardless of whether snx-swap.com is online. If the website ever becomes unavailable, you can interact with the same underlying smart contracts directly through Etherscan's Write Contract interface, or through any other Synthetix-compatible interface. Your staked SNX and sUSD debt exist on-chain, not on SNX Swap's servers.

To add SNX to MetaMask: On Ethereum mainnet, the SNX contract address is 0xC011a73ee8576Fb46F5E1c5751cA3B9Fe0af2a6F. On Optimism, it is 0x8700dAec35aF8Ff88c16BdF0418774CB3D7599B4. In MetaMask, go to Assets → Import Tokens → paste the contract address. MetaMask will automatically fetch the token name, symbol and decimals from the blockchain. SNX Swap's interface also includes a one-click "Add to MetaMask" button for both mainnet and Optimism SNX tokens visible in the token selector.

Synthetix is governed by a decentralized autonomous organization (DAO) consisting of multiple councils: the Spartan Council (core protocol decisions), Treasury Council (managing protocol funds), Ambassador Council (DeFi ecosystem relations) and Grants Council (funding community projects). SNX stakers vote in elections for council members every four months. To participate: stake SNX through SNX Swap, connect to governance.synthetix.io, and vote with your staked SNX voting weight. You can also submit governance proposals (SIPs — Synthetix Improvement Proposals) to the forum for community discussion.

For community support, join the official SNX Swap Discord and Telegram (links in the footer). Technical documentation is at snx-swap.com/docs. Security vulnerabilities should be submitted through the bug bounty program for responsible disclosure. For Synthetix protocol-level questions, the Synthetix Discord (discord.gg/synthetix) and governance forum (forum.synthetix.io) are the best resources. Remember: SNX Swap support will never DM you first, never ask for your seed phrase, and never ask you to send tokens to a "verification" address. Any such message is a scam.
