About expand.network

Blockdaemon provides seamless DeFi access through a unified API. Connect to 170+ DeFi endpoints, including DEXs, bridges, lending, oracles & more—all in one place.

DeFi API blockchain data infrastructure

expand.network is a powerful API infrastructure platform that bridges the gap between institutional DeFi access and on-chain execution. It offers a single, unified API to connect with over 45 blockchains and DeFi protocols, allowing institutions, developers, and data providers to easily interact with decentralized applications. Through expand.network, users can perform swaps, lending, borrowing, yield tracking, liquidity provisioning, and data querying—without needing to interact with multiple smart contracts or separate SDKs.

As the demand for multi-chain support and decentralized finance increases, expand.network has positioned itself as the go-to infrastructure provider for enterprises. It is wallet-agnostic, non-custodial, and built with developer efficiency in mind. From simplified pricing to extensive documentation and a live API testing environment, expand.network offers a frictionless way to access and operate across the DeFi ecosystem at scale.

expand.network is a comprehensive DeFi infrastructure platform delivering unified API access to a vast range of blockchains and protocols. With more than 170+ endpoints and support for 45+ chains, it allows developers and institutions to streamline their interaction with DeFi and Web3 protocols from a single point of integration. Whether you're sourcing token prices, executing swaps, retrieving on-chain data, or managing portfolios, the API structure is designed to be versatile and scalable.

The supported blockchain infrastructure includes both EVM-compatible chains (like Ethereum, Polygon, Arbitrum, Optimism, zkSync) and non-EVM chains (such as Solana, Algorand, Bitcoin, Near, Aptos, and Starknet). Additionally, protocols spanning DEXs, lending, staking, synthetics, and oracles are available through a single API layer. Examples include Uniswap, Aave, Curve, Chainlink, Synthetix, Lido, dYdX, and more.

By acting as a wrapper layer over numerous protocols and blockchain networks, expand.network simplifies interactions that would otherwise require separate SDKs and integrations. For example, developers can use one endpoint to get swap pricing across multiple DEXs or fetch transaction data from Solana and Binance Smart Chain without dealing with their distinct libraries.

Another key feature is the Expand Playground, a live API testing interface that allows users to explore available endpoints, filter by chain or protocol, and test parameters in real time. This is especially useful for developers building dashboards, trading bots, or analytics tools. The platform also includes built-in support for WalletConnect, enabling seamless connection to over 170 wallets including MetaMask, Trust Wallet, and Ledger.

As DeFi infrastructure continues to evolve, expand.network stands alongside other middleware services like Alchemy, QuickNode, and Infura. However, unlike general-purpose node providers, expand.network focuses heavily on financial use cases—optimizing for swaps, lending, portfolio insights, and yield strategies, while abstracting away technical complexities for institutional-grade users.

expand.network offers a suite of features and benefits that empower institutions and developers in the DeFi space:

Unified API Access: Interact with over 170 endpoints and 45+ blockchains and DeFi protocols using one standardized API structure.
Cross-Chain Capability: Fetch data or execute transactions across EVM and non-EVM chains without handling multiple SDKs or wallet integrations.
Full Trade Lifecycle Support: Access tools for swapping, lending, borrowing, adding/removing liquidity, and trade reconciliation.
Wallet Agnostic: Compatible with MetaMask, Trust Wallet, Ledger, and over 170 wallets via WalletConnect.
Live Testing Environment: The Expand Playground lets you explore and test endpoints before deploying them.
Efficient Price Discovery: Compare DEX rates through a single endpoint and ensure best execution with no smart contract middlemen.
Security First: All transactions are signed client-side. expand.network never has access to your private keys.
Flexible Pricing: From generous free tiers to scalable enterprise plans, the platform grows with your needs.

Getting started with expand.network is simple and developer-friendly:

Step 6 – Scale as Needed: Choose from a range of pricing plans depending on your request volume and compute needs.

expand.network FAQ

Yes. One of the core benefits of expand.network is that it acts as a unified API layer across multiple chains and protocols. Developers can interact with Ethereum, Solana, Polygon, zkSync, and more through a single interface without diving into the unique SDKs or libraries of each chain. Whether it's fetching a transaction or executing a swap, you only need to learn one API standard.
expand.network is completely non-custodial. All transactions are signed client-side using your connected wallet, such as MetaMask, Ledger, or WalletConnect. Your private key is never sent over the network or shared with the platform. This security-by-design approach ensures that your keys remain your keys, keeping control and custody in your hands at all times.
The Expand Playground is an interactive environment where users can live test over 170 API endpoints. Unlike static documentation, it allows developers to input real parameters, connect wallets, and instantly see the response structure. It supports filters by chain and protocol, making it an ideal tool for prototyping and verifying logic before pushing to production.
Yes. expand.network offers deep support for both EVM-compatible chains (like Ethereum, BSC, Polygon, Arbitrum) and non-EVM chains (such as Solana, Algorand, Sui, and Bitcoin). This makes it a truly cross-chain solution for projects needing access to a wide variety of networks from a single platform. The common API structure abstracts away protocol-level differences, saving development time and cost.
expand.network offers real-time access to pricing data from multiple DEXs and aggregators through a single API call. Developers can use endpoints like getprice to compare rates from Uniswap, Curve, PancakeSwap, Jupiter, Sushiswap, and others. This enables efficient price discovery and allows apps to route trades through the most favorable paths without additional smart contract logic.
