Bridge to Polkadot

Spacewalk is the first bridge between the Stellar network and the Polkadot ecosystem. Bridging to one of the most popular Web3 ecosystem gives Stellar users more access to DeFi opportunities. Based on already tested infrastructure (XCLAIM and interBTC), Spacewalk is implemented as a Substrate (the blockchain framework on which Polkadot is built) pallet and allows any Substrate-based blockchain to implement a direct Stellar bridge.

Stellar Oracle

A key component of the bridge is the Stellar oracle, which relays the state of the Stellar network to external services (like a bridge). The Stellar oracle is decentralized and by design at least as secure as the Stellar network itself.

While this oracle is developed with Spacewalk in mind, it can be used by other bridge services. By giving this oracle to the Stellar community, we hope to see more bridges being built to connect Stellar with the broader DeFi/Web3 world.
