Expand.network's unified API will help users to efficiently transact, source data, and build in the Stellar ecosystem.

Products & Services

Expand.network is an outsourced Web3 infrastructure provider, backed by Cumberland Labs, the Web3 incubator founded by the partners of Cumberland DRW. Our core offering is a unified API designed for efficiently transacting with chains and protocols and sourcing on-chain data, which saves our users significant time and money to access the vast, fragmented Web3 ecosystem. By leveraging our middleware, users can efficiently connect to over 100 distinct endpoints, including chains, DEXs, lending protocols, DEX & yield aggregators, oracles, bridges, and more. Essentially, Expand’s API serves as a single point of access for the Web3 ecosystem, allowing users to quickly and efficiently interact with over 40 different blockchains and protocols.

The Web3 ecosystem is vast, fragmented, and constantly changing. As a result, those building in Web3 and interacting with chains and protocols incur high resource costs and time delays to build and maintain integrations with multiple chains and protocols. This often hinders experimentation, innovation, and ecosystem in Web3. Our goal at Expand is to provide reliable infrastructure that reduces the barriers to iterating with blockchains and protocols, and helps to grow the Web3 ecosystem in an efficient, scalable, and secure manner. Expand’s API solves this problem by functioning as a single point of access for the Web3 ecosystem, allowing users to quickly and efficiently transact with the blockchains and protocols of their choice. By connecting to a single unified API, users can access over 40 chains and protocols and over 100 distinct endpoints, eliminating the need for users to build and maintain these integrations themselves. Users can get up and running more quickly, explore new chains and protocols more easily, and focus their attention on their core priorities.

Expand serves a broad user base that includes trading firms, asset managers & VCs, research analysts, wallets, dapps, tax & accounting firms, and other service providers. Given the diverse applications of the API, virtually every digital asset client type can potentially find valuable uses of the API for their needs. The API allows users to seamlessly transact across the Web3 ecosystem, access on-chain data, monitor chains and protocols, and build DeFi-related features like swaps and lending. Some examples of popular cases include Liquidity Pool Forensics, Portfolio Management, Trading, Transaction & Pool Analysis, and Trade Reconciliation. Whether you are a wallet looking to build swaps or lending features into your front end, a developer seeking to create a prototype, or a research analyst interested in analyzing and monitoring liquidity pools on decentralized exchanges, the Expand API is designed to assist you in achieving your goals more efficiently, saving both time and money.

Expand offers a single unified API with both read and write capabilities that users can leverage to access over 100 distinct Web3 endpoints and over 40 different chains and protocols. The Expand API is designed to be non-custodial and wallet agnostic, allowing the user to select the wallet of their choice when using the API, and preserving control and privacy over their keys at all times. Transactions occur in a secure three-part process: 1) First, a transaction is prepared using the expand.network API. 2) Then the transaction object is securely sent to the wallet for signing. 3) Finally, the Expand API will broadcast the encoded string to the respective chain.

Through this proposed integration, Expand’s API will provide users with direct connectivity to Stellar and Soroban RPC, allowing them to efficiently transact, source data, and build in the Stellar ecosystem. The proposed integration will be designed as an HTTP REST API service, serving as an intermediary between users and the Stellar Network. Leveraging the native Stellar SDK, our system will facilitate end-to-end interactions with the network and enable the execution of various functions.
