Rock’n’Block joins Rubic to bring its Best Rate Finder to Stellar

Rock’n’Block is working with Rubic to bring its Best Rate Finder to Stellar. Awarded through the Stellar Community Fund, we’ve begun development on an integration that will connect Stellar to Rubic’s ecosystem of 70+ blockchains and over 360 DEXs, bridges, and intent-based protocols.

For Stellar projects, this integration will provide access to multichain liquidity and new users. For Rubic’s community, it will enable faster, low-cost transactions on Stellar without leaving the swap flow they already use.

Stellar Community Fund Award

This initiative received an SCF award after passing several voting rounds, reflecting strong interest from the Stellar community. The award makes this integration possible and underscores a commitment to practical, reliable multichain solutions.

Development Phases

This integration effort is structured in stages. The MVP will establish initial Stellar routing and connect key liquidity providers. During the testnet phase, wallet support, multihop routing, and fee contract testing will be added. The mainnet rollout will complete the aggregator, enable full provider access, and deploy smart contracts for fees. Updates on progress and timelines will be shared with the community as milestones are reached.

Rock’n’Block’s Role

Rock’n’Block is leading the technical implementation of Stellar within Rubic’s aggregator. This includes connecting Stellar DEXs like SoroSwap and bridges like AllBridge, enabling multihop swaps across chains, supporting wallets such as Lobstr, and building a dedicated Stellar Aggregator API to calculate quotes and manage swap execution at scale.

Why This Matters

Once live, developers, wallets, and dApps will have an easier way to move assets into and out of Stellar. Users will be able to swap tokens across chains without needing to manage multiple bridges or liquidity sources manually, creating more seamless multichain experiences.
