How We Differ
CrossCall vs. Crosschain Messaging Protocols
Axelar, Hyperlane, CCIP, LayerZero, and similar infrastructure all share the same fundamental model:
A user initiates a message on an origin chain → the message triggers a transaction on a destination chain.
This requires the user to have funds and gas on the origin chain, and it requires the destination-side execution to be pre-funded or subsidized separately.
CrossCall does the opposite.
Solvers in the CrossCall network execute transactions directly on the destination chain, from the signer's smart contract wallet — covering execution, validation, and gas costs upfront. The crosschain messaging layer (Hyperlane) is used exclusively for the solver's payout, not for the user's transaction.
The Key Inversion
| Standard Crosschain Messaging | CrossCall | |
|---|---|---|
| What crosses the chain? | The user's transaction intent | The solver's payout |
| Who fronts execution? | User (must have funds on destination) | Solver (repaid atomically) |
| Liquidity model | Bridge pools or pre-funded contracts | Solver-user atomic P2P |
| Bridge risk exposure | User bears bridge risk | No bridge in the user's flow |
| Speed | Confirmation + bridge delay | Immediate (solver-fronted) |
Structural Advantages
Decentralized liquidity. There are no bridge pools. Every execution is a direct atomic transaction between a solver and a user. The attack surface of a centralized pool simply doesn't exist.
No destination chain requirement. Users never need funds, gas tokens, or a wallet presence on the destination chain. From their perspective, they're executing on their native chain.
Instant finality. Because solvers front execution, users don't wait for crosschain confirmations. They see their transaction execute immediately.
Protocol-agnostic. CrossCall is generalized. Any protocol that can express calldata can use CrossCall — DEX aggregators, NFT marketplaces, bridges, lending protocols, and more.
CrossCall's Relationship with Hyperlane
CrossCall is built on top of Hyperlane, not in competition with it. Hyperlane provides the authenticated crosschain messaging layer that makes solver payouts deterministic. Without Hyperlane, CrossCall would need its own validator network. With Hyperlane, it inherits a proven, decentralized message bus.
The CrossCall Paymaster integrates with the Hyperlane IGP (Interchain Gas Paymaster) to quote and pay for message delivery atomically within the solver's bundle — so the payout message is only submitted if the user's transaction actually executed.
