Stellar and its smart contract platform, Soroban, are increasingly integrating with the Polkadot ecosystem through Spacewalk bridge. Spacewalk facilitates seamless asset transfers for the multitude of Stellar’s fiat stablecoins (like BRL, EURC, TZS and more) between Stellar and Polkadot.

Stellar and Soroban

Stellar’s network, powered by the Stellar Consensus Protocol (SCP), offers a wide range of stablecoin anchors including many exotic stablecoins and their local on/off ramps. Stellar is an OG ecosystem founded in 2014 that have recently launched Soroban, a new smart contract platform, to connect their ecosystem with DeFi functionalities.

Soroban utilizes Rust-based smart contracts, facilitating the creation of performance-optimized and secure dApps. It uniquely complements Polkadot’s existing structures by offering tools for developing complex financial tools and services, further bridging the gap between traditional finance and decentralized finance.

Pendulum’s Spacewalk Bridge In Action

The Spacewalk bridge is a cornerstone of this integration, enabling the fluid movement of assets between Stellar and Polkadot. It supports various fiat-backed stablecoins and cryptocurrencies, enhancing the utility of Stellar’s network within Polkadot’s DeFi landscape.

The bridge not only simplifies transactions but also aligns with Pendulum’s goal of broadening financial inclusion and connectivity across blockchain platforms.

Stellar’s integration into the Polkadot ecosystem through the Spacewalk bridge brings many solutions to existing challenges and enhances the overall efficiency of cross-chain transactions.

Moreover, Soroban’s smart contract capabilities provide Polkadot developers with new tools for creating decentralized applications, particularly in the sectors of decentralized finance (DeFi) and cross-border payments.

Payments on Stellar

As depicted in the graph, Stellar’s payment activity has been on a steady rise, reflecting its growing influence as a reliable platform for businesses and individuals seeking efficient financial solutions. This surge in payment processing underscores Stellar’s potential as a key player in the global financial landscape.

Use Cases and Potential Collaborations

The synergy between Stellar, Soroban, and Polkadot opens up numerous possibilities for collaborative projects. Potential use cases include cross-chain financial products that integrate Stellar’s currency exchange with Polkadot’s scalable infrastructure.

Pendulum’s new EURC off-ramp prototype offers a seamless integration for Polkadot users to transfer their EURC directly to a bank account with just a few clicks. Leveraging Stellar and Spacewalk on the backend, the platform ensures a smooth and user-friendly experience.

Additionally, Soroban’s smart contracts can be paired with Polkadot’s parachains to innovate in areas like decentralized finance and cross-border payments.

Unlocking New Markets for Polkadot

Pendulum unlocked the vast potential of traditional financial markets for Polkadot users, catering to users and businesses primarily operating in fiat currencies. This gateway could significantly expand the reach and adoption potential of Polkadot-based projects.
