Multichain Intent Routing with Rhinestone

Multichain Intent Routing with Rhinestone

Automated multichain bridging via Rhinestone is live on Solana, powered by Swig

Crypto is increasingly multichain, but moving funds across networks is a manual, opaque process that requires advanced domain expertise. A simple cross-chain deposit can turn into a sequence of multi-signature approvals, excessive slippage, burdensome gas management, and waiting around to confirm whether assets arrived in the right place.

For developers, the problem is just as painful. Every bridge adds new trust assumptions, security risks, and engineering overhead to manage a spectrum of messaging standards. Bridging complexity slows users down and causes mistrust, both of which lead to churn in your applications.

With Swig, Rhinestone is solving bridging, deposit and withdrawal UX to and from Solana. Rhinestone provides a cross-chain intent engine for flexibly moving funds between EVM chains and Solana with one API call. Swig smart wallets now power Rhinestone’s Solana account layer, giving Rhinestone programmable wallet infrastructure for secure, policy-based cross-chain flows.

What is Rhinestone?

Rhinestone provides smart wallet and orchestration infrastructure for developers who need seamless onchain UX. This infrastructure previously targeted EVM chains only, but now with Swig is expanding to include Solana. One of crypto’s biggest frictions is funding an application when you have the wrong token on the wrong chain for the application you want to use. Rhinestone’s deposit product solves this pain point. It finds and executes optimal bridging and swap routes automatically, creating one seamless hosted flow for application deposits no matter the source chain or token.

Instead of asking users to pick a bridge, hold the right gas token, sign across multiple steps, and track settlement manually, Rhinestone turns the flow into a single intent. Users direct where funds should settle. Rhinestone handles the routing, execution, and relay path behind the scenes.

Rhinestone uses Swig on Solana to accept inbound transfers from origin chains, and routes them into destination wallets through programmable smart wallet policies.

How Swig helps

Cross-chain deposits require more than a receiving address. They require wallet infrastructure that enforces a relayer’s permissions, executes transactions reliably without asking users to sign every step, and keeps routing logic constrained to discrete instructions.

By leveraging Swig programmable smart wallets, Rhinestone automates execution on Solana while preserving clear policy boundaries. With policy-based routing through Swig, Rhinestone’s cross-chain deposits become faster, more predictable flows. Less app-hopping required.

Why this matters

The best cross-chain UX is one that a user barely notices. Users should not need to understand bridge liquidity, route selection, or operational differences between EVM and Solana accounts just to move funds between wallets.

That abstraction is especially important as Solana becomes a destination for battle-tested products that need quick settlement, low fees, and strong execution performance.

Swig’s integration with Rhinestone makes that possible. Users can now move between Solana and EVM chains through a single API-driven flow, with sub-2-second confirmations from origin to destination chain.

Cross-chain infrastructure should feel less like a sequence of handoffs and more like a single product action. Rhinestone is pushing that experience forward with its cross-chain intent system, and Swig is proud to power the Solana wallet infrastructure behind it.
