  Rhinestone Chain Abstraction (Warp) — Technical Summary

  What It Is

  Rhinestone Warp is an intent-based cross-chain execution engine built on ERC-7579 smart account modules. Users express desired outcomes ("send 100 USDC
  from Optimism to Base and deposit into a vault"), and a competitive solver/relayer market fulfills them — handling bridging, swapping, and gas
  abstraction transparently.

  ★ Insight ─────────────────────────────────────
  1. ERC-7683 standardization — Rhinestone implements the ERC-7683 cross-chain intent standard, which defines a generic order struct and settlement
  contract interface. This is the same standard that Across, UniswapX, and other intent protocols converge on. Newton's policy evaluation could validate
  ERC-7683 orders before they reach the solver market.
  2. ERC-7579 modular accounts — The Intent Executor is installed as an ERC-7579 module on smart accounts. Newton could potentially ship as an adjacent
  ERC-7579 validator module that enforces policy checks before the Intent Executor fires.
  3. Permit2-based signing — The EIP-712 signature scheme wraps PermitBatchWitnessTransferFrom with a nested Mandate struct. This means intent
  authorization is already structured data — perfect for Newton's Rego policy evaluation.

  Intent Lifecycle

  1. Quote    → POST /intents/route (get intentOp + cost + token requirements)
  2. Prepare  → Fulfill token requirements (ERC-20 approvals to Permit2, ETH→WETH wraps)
  3. Sign     → EIP-712 sign each element (per input chain), reuse final sig for destination
  4. Submit   → POST /intent-operations (signed intentOp → Orchestrator → solver market)
  5. Fill     → Solver fills on destination chain (tokens + calldata execution)
  6. Claim    → Origin chain settlement (repay solver via settlement layer)
  7. Complete → Status transitions: PENDING → PRECONFIRMED → FILLED → CLAIMED → COMPLETED

  Each intent breaks into elements (one per input chain-token pair), each independently routable to different settlement layers.

  Key Data Structures

  Intent Route Request (the "quote"):
  {
    account: { address, accountType: "EOA"|"smartAccount"|"ERC7579", setupOps },
    destinationChainId: 8453,           // e.g. Base

  }

  IntentOp Element (per input chain):
  {
    arbiter: address,
    chainId: number,
    idsAndAmounts: [{ id, amount }],      // token ID = lowest 160 bits = token address
    mandate: {
      recipient, tokenOut, fillDeadline,

  Supported Chains

  Mainnet (10): Ethereum (1), Base (8453), Optimism (10), Arbitrum (42161), Polygon (137), Avalanche (43114), Gnosis (100), Scroll (534352), BNB Chain
  (56), ZKsync Era (324)

  Testnet (9): Sepolia, Base Sepolia, OP Sepolia, Arb Sepolia, Polygon Amoy, Avalanche Fuji, Scroll Sepolia, BNB Testnet, ZKsync Sepolia

  EIP-712 Signing Scheme

  The signature wraps a Permit2 PermitBatchWitnessTransferFrom with a nested Mandate witness type. For multi-chain intents:
  - One signature per input chain element
  - Final signature is reused for destination chain validation
  - Domain separation ensures cross-chain safety
  - Qualifiers are keccak256-hashed before inclusion in typed data

  Smart Sessions (Policy Layer)

  Rhinestone has its own on-chain policy framework via Smart Sessions (ERC-7579 validator module):

  ┌────────────────┬────────────────────────────────────────────────┐
  │  Policy Type   │                  Description                   │
  ├────────────────┼────────────────────────────────────────────────┤
  │ Sudo           │ Unrestricted (no constraints)                  │
  ├────────────────┼────────────────────────────────────────────────┤
  │ Call           │ Restrict by target address + function selector │
  ├────────────────┼────────────────────────────────────────────────┤
  │ Spending Limit │ Cap ERC-20 transfer/approve amounts            │
  ├────────────────┼────────────────────────────────────────────────┤
  │ Timeframe      │ Time-windowed access                           │
  ├────────────────┼────────────────────────────────────────────────┤
  │ Usage Limit    │ Max transaction count                          │
  ├────────────────┼────────────────────────────────────────────────┤
  │ Value Limit    │ Cap native ETH transfers                       │
  └────────────────┴────────────────────────────────────────────────┘

  Sessions combine Owners (ECDSA/multisig/passkey) + Actions (OR logic) + Policies (AND logic).

  Fee Structure

  - Core infra + SDK: Free, open source
  - Same-chain intents: No fee
  - Cross-chain: 3 bps during private beta
  - No API fee
  - Gas costs: Borne by client; solvers earn a small gas premium

  Integration Opportunities with Newton

  ★ Insight ─────────────────────────────────────
  1. Newton as a pre-execution policy gate — Rhinestone's Orchestrator routes intents before solvers fill them. Newton could sit between the Orchestrator
  and the solver market, validating that each intent complies with policy (AML, spending limits, whitelisted counterparties) before it's broadcast. The
  destinationExecutions field (arbitrary calldata) is especially policy-relevant — it could encode DeFi interactions that need compliance checks.
  2. Newton validator module for smart accounts — Rhinestone's Smart Sessions already has a policy framework, but it's limited to on-chain checks (spending
   limits, timeframes). Newton's Rego-based policies can express much richer logic (off-chain data, oracle feeds, identity checks) and provide BLS-attested
   proofs of compliance. A Newton ERC-7579 validator module could enforce policies that Smart Sessions can't express.
  3. Overlapping chain coverage — Rhinestone supports all of Newton's target chains (Ethereum, Base, Optimism, Arbitrum, Polygon). Newton's multichain
  gateway architecture (Gateway::from_multi_chain_config()) already handles per-chain routing, which maps well to Rhinestone's per-chain intent elements.
