Spacewalk – a trustless decentralized multiasset bridge for Polkadot
Spacewalk is a framework for trust-minimized and decentralized bridges. It enables Polkadot parachains to connect to various blockchains in a unified manner. Spacewalk solves multiple challenges that bridge builders encounter, e.g., when the connecting to chains don’t support smart contracts or SPV. As an example we present a bridge to Stellar that supports multiple assets and stable coins and share our concept for bridging to other chains like Solana and the Cosmos ecosystem.
