Decentralized exchanges (DEXs) present strong safety features by their non-custodial frameworks, which don’t depend on a centralized system, in addition to good contracts that can not be modified, in contrast to centralized exchanges (CEXs) which comprise centralized honeypots which could be a goal for hackers. Nonetheless, in follow, DEXs do face points with vulnerabilities in coding, as do CEXs with threats coming from insiders together with overreaching guidelines and laws. Builders and merchants want to investigate the safety of each CEXs and DEXs. This paper makes use of Dexlyn and comparable DEXrs to spotlight the elemental strengths and weaknesses of DEXs in the true world.
Elementary DEX Safety
Dexlyn, like different DEXs, makes use of the automated market maker (AMM) protocol, which permits customers to maintain their non-public keys and work together immediately with the on-chain good contracts. With this non-custodial structure, funds can’t be frozen, and particular person accounts can’t be accessed, which is a key benefit over CEXs whose wallets are custodial. Dexlyn’s construction consists of liquidity swimming pools which are audited and mechanically enforced with atomic swaps from Solidity contracts. Which means trades can reverse if they aren’t accomplished and don’t expose any reserves.
Different DEXs, together with PancakeSwap on BNB Chain, use the identical fixed product algorithm which is configured as x * y = okay, through which balances of a pool are stored in equilibrium with none off-chain interference. Dexlyn, nonetheless, enhances this with cross-chain bridges utilizing Supra and EVM ecosystems and employs timelock validators to enhance safety for asset transfers and scale back dependency on oracles, that are incessantly discovered on platforms like THORChain.
CEX Safety Limitations
When a CEX centralizes belongings, it shops them in each cold and hot wallets that are managed by inside groups. These centralized groups create a brand new loss potential as a result of privilege entry and server-side breach dangers. Whereas some wallets make the most of multi-signature schemes and {hardware} safety modules, API endpoints stay susceptible to information leaks. Platforms like Binance, whereas counting on enterprise monitoring, endure outages on account of DDoS assaults or regulatory compliance. These outages influence thousands and thousands of customers, whereas decentralized exchanges (DEX) are open 24/7 as a result of permanence of the blockchain.
Person authentication through 2FA and biometric checks are useful, however KYC (Know Your Buyer) information assortment leaves a consumer’s identification susceptible to theft. Dexlyn circumvents this, providing customers pseudonymity and avoiding account freezes, which will increase customers’ rights, permits customers to manage their very own information, and complies with Web3 regulatory frameworks.
Dexlyn’s Audit-Pushed Protections
Dexlyn units the usual for DEX safety by acquiring unbiased, and public, audits from Hacken Membership and CDSecurity, which consider audits for core contract assaults. These assaults embrace reentrancy, overflow, and entry management assaults. Dexlyn has chosen to self-impose the integrity of their audits with the non-upgradable function of their DEX, which prevents runtime modifications that different DEXs could expose. Dexlyn’s protections towards sandwich assaults embrace anti-MEV oracles and liquidity companies which add to the dynamic slippage controls.
Dexlyn makes use of Merkle proofs for cross-chain performance and bridge validation, making certain that information from the Supra-EVM transfers to Dexlyn’s and different EVMs with no non-public information uncovered. Dexlyn’s EVM focus is a noticeable enchancment over Raydium on Solana due to the broad vary of appropriate developer instruments, equivalent to Etherscan verification. This promotes an enterprise developer belief to facilitate growth and integration.
Comparative Technical Fashions
Danger distribution in code and customers in DEXs, towards infrastructure centralized in CEXs. Twin-audit mannequin in Dexlyn reduces the chance in exterior calls DEXs distribute threat throughout code and customers, whereas CEXs focus it in infrastructure
Safeguards in Main DEXs
For governance, PancakeSwap deploys multi-party computation (MPC), due to this fact, decreasing the surfaces of assaults of 51% on the emissions of the tokens. Dexlyn mirrors this with immutable farms, the place the logic of yield is programmed to forestall integer underflows of the reward calculations utilizing checked arithmetic. Each embrace pause proxies, which act as circuit breakers within the final resort, for use solely by multisig oracles.
These practices emphasize the usage of sure instruments, equivalent to Slither, to scan for weaknesses (SWC) within the code to confirm it formally pre-deployment.
Methods for Mitigating Dangers at CEX
To mitigate dangers, CEX employs real-time SIEM programs together with Chainalysis for on-chain tracing, permitting them to rapidly freeze funds. Greater than 90% of their belongings are stored in chilly storage, which is secured with air-gapped HSMsand Shamir’s Secret Sharing. Nonetheless, the worker key rotations and SOC 2 compliance don’t totally tackle social engineering and phishing, which bypass {hardware} tokens.
Their restoration mechanisms are helpful to central exchanges, as assist groups are in a position to restore misplaced accounts. In distinction, decentralized exchanges (DEXs) centralize accounts. Nonetheless, this presents the chance of governmental seizures, which isn’t current in Dexlyn’s bearer-asset mannequin.
Person Suggestions for Every Platform
When utilizing DEXs, equivalent to when buying and selling on Dexlyn, customers ought to evaluate the documentation and the obtainable audits earlier than making swaps. Customers also needs to make the most of {hardware} wallets (e.g. Trezor) for transaction approvals.By way of slippage, customers ought to manually set their slippage to 1–2% for extra risky pairs. Customers can also make the most of the simulate possibility on tender.ly.When utilizing CEXs, be sure that two-factor authentication (2FA) is ready up with a {hardware} key (e.g. YubiKey). After making a fiat on-ramp, withdraw belongings to a DEX.When utilizing each CEXs and DEXs, use the CEX for exploration and use Dexlyn for the buying and selling. You should use APIs to bridge portfolios.When used individually, Dune Analytics affords pool well being, and DeFiLlama exhibits audits of Complete Worth Locked (TVL).As Dexlyn has finished, builders should prioritize bugs that could be current in programs, as white-hat hackers can convey priceless scrutiny.
Establishing Balanced Commerce-Offs
Dexlyn DEXs are sovereign, but require a level of DEX technical self-discipline, contract verification by the Remix IDE. CEXs are a trade-off in scaling comfort for structural cross threat. On the identical time, DEXs profit from simple consumer expertise layered on Dexlyn’s strong code.
DeFi’s evolution sees hybrid fashions dominate; CEXs feeding DEXs. Dexlyn’s immutable and auditable design proves that DEXs can surpass CEXs.
Reworking Safety Panorama
DEXs like Dexlyn are reshaping how safe buying and selling may be. By specializing in code immutability and consumer empowerment as a substitute of centralized conveniences, they present how buying and selling may be finished in a very safe method, particularly in DeFi’s excessive stakes world. As blockchains combine with ZK-rollups and AI primarily based audits , the structure of DEXs will proceed to be forward of the vulnerabilities of CEXs. This can empower each builders and merchants to create the monetary future they need.
