Rhinestone combines smart wallet infrastructure with an intent-based transaction system to offer the ultimate abstraction layer for teams building muilti-chain applications.

​
Tech Stack Visualization

Rhinestone offers three core services:
  • Modular Smart Account toolkit, compatible with all major key management solutions
  • An Intent Engine for single- and multi-chain transaction and swap routing
  • A Relayer Market that aggregates solver liquidity for intent execution

​
Smart Accounts

Rhinestone develops the onchain infrastructure for smart wallets, including the smart account and modules that extend the wallet with specific features. Rhinestone’s core modules include:
  • Passkeys for secure and user-friendly self-custodial key management
  • Session keys for transaction automation
  • Multi-sig for high value accounts
  • Social login (through an embedded wallet integration)
  • Recovery for a heightened security
Use these onchain components via the Rhinestone SDK to deploy, configure, and manage smart accounts for your users.

​
Intent Engine

Rhinestone provides a modular intent engine that aggregates existing crosschain settlement layers through a unified relayer market. It utilizes resource locks for blazing fast crosschain execution and a sophisticated offchain solver for routing, transaction encoding, and orchestration. Key Features:
  • Crosschain transactions: Eliminate chains and bridges to make a multi-chain experience feel like a single chain.
  • Swaps: Use Rhinestone’s relayers for solver-based swaps with zero-slippage and MEV protection or inject a swap via a DEX aggregator.
  • Universal gas sponsorship: Deposit USDC on your developer account on Base and sponsor gas, bridging, and swap fees on any chain.
  • Multi-input intents: Rhinestone intents can include any number of input chains and input tokens, whilst maintaining the signal-signature UX.
  • Atomic and deterministic: Unlike bridges, Rhinestone intents are atomic and have a known output token with zero slippage (deterministic).
  • Human-readable signatures: An EIP-712 signature envelope guarantees a legible payload to be signed by the user, no matter the complexity of the intent.

​
Relayer Market

We aggregate settlement layers (such as Across, Relay, and Eco) through a unified intent layer. This allows application developers to integrate smart wallet features and aggregate multiple settlement layers out of the box with one unified SDK and API. More on the Relayer Market.

​
Rhinestone is Composable

Rhinestone’s modular tech stack allows us to meet clients where they are:
  • Compatible with all signers: Use passkeys, any external wallet, or embedded wallet (such as Turnkey, Dynamic, Magic, Privy, etc) to sign intents.
  • Account Implementation-agnostic: Rhinestone works with all major smart account implementations that follow the ERC-7579 spec or utilise ERC-7821 for batched execution.
  • Modular Smart Account: Customize your smart wallet with modules or build custom components to extend the wallet functionality.
  • Quote API Only: Our intent routes can be consumed via the quote API for crosschain intents and swap quotes - without the integration of Rhinestone smart wallets.
