Core

Yes, your transactions are secure with GlueX. Our routing smart contracts and API infrastructure are built with advanced security features to safeguard against common DeFi risks such as front running and sandwich attacks. Additionally, we implement extra protections like Surge Protection to ensure reliable and safe onchain interactions for all users
GlueX supports a broad and growing range of EVM compatible chains. While the exact list is constantly updated, this typically includes major networks like Ethereum Mainnet, Polygon, Binance Smart Chain, Arbitrum, Optimism, Avalanche and many others. Refer to our supported networks for the most current list of supported chains
Through GlueX, you can execute a comprehensive range of DeFi transactions including: token swaps (DEX aggregation), cross chain asset bridging, lending, staking, yield farming, zaps(multi-step DeFi actions into one transaction) and our unique ‘swidge’ operations (swap + bridge)
GlueX stands out by offering not just DEX aggregation but a holistic DeFi API suite covering bridging, lending, staking and complex operations like ‘swidge’ across multiple chains. Our intelligent routing optimizes for the best price, slippage and gas fees, providing a more comprehensive solution than many single focus aggregators
GlueX uses advanced smart order routing algorithms that aggregate liquidity from numerous DEXs and AMMs across all supported EVM chains. It dynamically analyzes real time market data to find the most efficient and cost effective paths for your token swaps, minimizing slippage and maximizing output
Transaction limits can vary depending on the liquidity available for specific token pairs and chains, as well as any network specific constraints. While GlueX aims to facilitate transactions of all sizes, very large transactions might be split across multiple liquidity sources for optimal execution
GlueX continuously expands its integration with a wide array of major DeFi protocols for liquidity, lending, staking and more. Our goal is to provide comprehensive access to the DeFi ecosystem. For a list of specific integrated protocols, please check the liquidity modules section
MEV (Maximal Extractable Value) resistance in GlueX refers to features designed to protect your transactions from malicious MEV attacks like front running and sandwich attacks, where bots attempt to profit from your trades. Our routing mechanisms aim to minimize these risks to ensure fair execution
Yes, GlueX APIs are built with robustness and scalability that make them suitable for institutional clients seeking secure, efficient and programmatic access to DeFi markets and operations. We can provide tailored solutions and support for higher volume usage
GlueX optimizes for gas efficiency by finding the most gas efficient routes and packaging complex transactions into minimal onchain calls. While users still pay network gas fees, GlueX aims to reduce the overall cost by optimizing the transaction structure

​
Integration and API

Some GlueX API endpoints require an API key for access, while others may allow public usage or offer elevated rate limits with a key. API keys are typically passed in the request header as x-api-key. For details on authentication requirements and usage, see our API Reference
The /price endpoint typically provides a snapshot of the current market price for a given token pair, often without considering the impact of a specific trade size or routing. The /quote endpoint, on the other hand, provides a concrete proposal for a specific transaction (eg: for a certain amount of tokens), including the calculated output amount, estimated gas fees, and potential slippage by performing an actual route calculation
Surge Protection is a built in pre trade safety mechanism designed to safeguard users from significant value loss during periods of shallow liquidity, extreme market volatility or abrupt price movements
You can obtain your unique Integrator ID and API Key by registering on the GlueX Developer Portal. These credentials are required to authenticate your API requests and unlock access to GlueX services
Yes, GlueX provides flexible integration options. While we offer dedicated widget and ui components for popular frameworks, and you can also integrate the widget as an iframe into virtually any web application, regardless of the underlying frontend framework
GlueX currently operates exclusively on mainnet and does not provide a testnet environment. For development and integration testing, we recommend using small value transactions on supported L2s. Stay tuned for updates, as testnet support may be added in the future
GlueX API responses include standard HTTP status codes and detailed error messages in the response body. Your application should implement robust error handling logic to parse these responses, notify users and manage retries or alternative flows as necessary. Refer to our API Reference for a list of common error codes and their meanings
Common troubleshooting steps include verifying your keys, checking network connectivity, ensuring correct endpoints, validating request body parameters, inspecting response error messages and reviewing our documentation for the specific endpoint you are using.
