Products & Services

Band Protocol is a leading cross-chain data oracle provider that aggregates and connects real-world data and APIs to smart contracts. In addition to our flagship oracle product and network, we’ve just launched a verifiable random function (VRF), which allows smart contracts to securely generate a random value and provide proof.

BandChain is based on Cosmos SDK, designed to be compatible with all smart contract platforms and blockchain development frameworks. In a trustless and decentralized manner, BandChain does all the heavy lifting jobs of pulling data from external sources, aggregating, and packaging them into a format that is easy to use and cryptographically verified across multiple blockchains. Unlike general-purpose blockchains, BandChain is designed explicitly for oracle data requests and computation. Data request transactions are both received and resolved very quickly, with an average block time of 3 seconds. We currently provide cryptocurrencies, foreign exchange rates, and commodity prices on 19 chains, including Ethereum, BNB Chain, Avalanche, Cronos, and we've also integrated with multiple projects on their testnets. Band Protocol work with different chains and Defi apps like lending protocols, perpetual protocols, and yield protocols to feed them accurate real-world data. Furthermore, our data source scripts and oracle scripts allow maximum customization and flexibility for the user to query and compute their desired data feed.

As for our VRF, Randomness is a fundamental function that helps to operate many decentralized applications (dApps). However, the root and foundation of this vital randomness mechanism are often neglected. Band’s VRF service addresses the fundamental issues that threaten the integrity of various Web3 use cases by providing a pseudorandom output along with proof of authenticity that validates the random number generation process. Four main features of our VRF include unpredictability, unbiased, verifiable, and tamper-proof.

Additional information

Since Stellar has a strong foundation and ecosystem, we believe that many talented builders will be building on Soroban. Having said that, we've already asked our technical team to look over the technical specifications and documents of Soroban. Given that our technical team has multiple experiences in integrating with EVM, WASM, and Rust-based projects in the past, we believe that we have the expertise in integrating with Soroban and therefore provide solid services for dapps wanting to build on Soroban.
