Overview

All of Web3 and DeFi in One Unified API

expand.network offers a single unified API for transacting and sourcing on-chain data.

expand.network's middleware API allows clients to transact and source on-chain data from 140+ endpoints, including DEXs, bridges, lending protocols, yield aggregators, oracles, NFTs, and stablecoins.

Simplify blockchain interactions, build efficiently, and access on-chain data with an abstracted connector API.

We currently support the following blockchains:

Blockchain type	Blockchains
EVM compatible	Arbitrum, Avalanche, Base, Binance Smart Chain, Cronos, Ethereum, Fantom, Optimism, Polygon, zkSync
Non-EVM	Algorand, Aptos, NEAR, Solana, Starknet, Stellar, Sui, TON, Tron, Cosmos Hub, Stacks, Bitcoin, Stellar, XRP Ledger

In addition, we currently support the following DeFi protocols:

Protocol type	Protocol
Bridge	Stargate, Squid Router
DEX & Aggregators	0x, 1inch, Balancer, Curve, Kyberswap, Pancakeswap (V2, V3), Sushiswap, Trader Joe, Uniswap (V2, V3, X), Orca, Raydium, SDEX
Derivative	dYdX V4
Lend and Borrow	Aave V2, Aave V3, Compound V2, Compound V3
Liquid Staking	Lido V2, Stader, Benqi, Jito
Oracle	Chainlink, Pyth Network, Winklink
Synthetic	Synthetix
Yield aggregator	Harvest finance, Yearn finance

All transactions are securely signed on your end, so your private key remains with you and never comes to us over API. We do not hold your crypto at any point: your keys, your crypto. Our APIs are a one-stop shop for you to make the enquiries and conduct the transactions as you want.

We provide two high-level categories for the simplicity of developers.

• Blockchains - Communicate with the various public blockchains to pull real-time information about blocks, transactions, slots (storage), balance, and many more. This can also be used to sign and send transactions to the chain. For example, if you need to check the transaction for the given transaction hash from Solana as well as the Binance smart chain, you need not learn about two different web3 libraries (Solana and BSC), you can easily do it using our common API endpoint, gettransaction.

• Protocols - There are multiple protocols available on the various chains. expand.network aims to provide interaction with a maximum of them based on various subcategories (Please refer to the categories section for details). For example, if you need to check the swap price of Token A to Token B on Uniswap V3 and Sushiswap, you need not learn about two different protocols, they can easily do it using our common API, getprice.

Good to know: expand.network is a wrapper across the various available web3 blockchains and protocols.

FYI: Our API responses are provided in the smallest unit of measurement for each respective item.
