Native Execution (Multi-Chain)

The Redeployment Problem​

Protocols like OpenSea (10+ chains) and Magic Eden spend enormous resources just to exist on each new chain. Expanding to a new chain means:

  • Redeploying all contracts
  • Modifying backend infrastructure
  • Re-indexing and re-integrating
  • Bootstrapping new liquidity

And the burden compounds with each new chain. CrossCall provides an exit.

How It Works​

With CrossCall, a protocol doesn't need to deploy on a new chain for users on that chain to interact with it. Instead:

  1. The user on the new chain signs a call intent targeting the protocol's existing contract on the protocol's native chain.
  2. A CrossCall solver executes the transaction natively on the protocol's chain, as if the user were a local participant.
  3. The user's funds on their origin chain pay for it — without ever touching the destination.

From the user's perspective, they're using their wallet on their chain. From the protocol's perspective, they received a standard native transaction. CrossCall is invisible.

Example: NFT Marketplace​

A user on Dogechain wants to buy an NFT listed on Magic Eden's Polygon market. Prices are shown in DOGE, but the NFT and the orderbook live on Polygon.

Without CrossCall:

  • User bridges DOGE → Polygon (slow, risky, requires MATIC for gas)
  • User executes the purchase on Polygon
  • User bridges back if they want funds on Dogechain again

With CrossCall:

  • User signs a call intent on Dogechain targeting Magic Eden's Polygon contract
  • Solver executes the purchase natively on Polygon
  • User's DOGE escrow on Dogechain pays the solver
  • NFT is delivered. Done. No bridging.

The protocol (Magic Eden) doesn't change anything. They never deployed on Dogechain. But Dogechain users can buy their listings.

Applicability​

This same pattern applies to any protocol interaction that can be expressed as calldata:

  • Lending protocols — users on Chain A can open positions on a lending protocol deployed on Chain B
  • Perpetuals — users can trade on any perp protocol from any chain
  • Launchpads — users on any chain can participate in IDOs on the launchpad's native chain
  • DAOs — governance participation without bridging to the DAO's native chain
