Tech Stack Visualization
- Modular Smart Account toolkit, compatible with all major embedded wallet signers
- 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
Intent Engine
Rhinestone offers an intent-based transaction service, called Warp, that aggregates existing crosschain settlement layers through a single solver market (the Relayer Market). It utilizes resource locks for fast crosschain execution (sub 2 seconds) and a backend service for routing, transaction encoding, and crosschain 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
Warp aggregates settlement layers (like Across, Relay, and Eco) for crosschain execution through a unified Relayer Market. This enables extreme flexibility when it comes to solving user intents. Instead of aggregating bridge APIs, the user intent is propagated to a chosen solver in the Relayer Market, and this solver supplies liquidity, can perform swaps, and interacts directly with onchain protocols for crosschain settlement.

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.
