Protocol Architecture/Features

The MANTIS framework is architected with the following components:

  • Cross-Domain Communication via the IBC
  • Multi-Domain Auctions
  • Language for Execution
  • Verifiable Settlement

Cross-Domain Communication via the IBC

MANTIS leverages Composable’s IBC bridge to facilitate cross-chain intent settlement. Our trust-minimized bridge in turn leverages the Inter-Blockchain Communication (IBC) Protocol. We have already connected Polkadot, Kusama, and Cosmos/the Interchain to this bridge, with expansion to Solana and Ethereum in the works.

Multi-Domain Auctions

User intents are scored based on volume cleared, with solutions being screened for MEV and bundled into a block for each domain. Searchers can tip for priority, and finalized blocks are embedded with validity predicates and sent to builders. This is depicted below:


Language for Execution: The Composable Virtual Machine

When the best solution is found, it is turned into a Composable Virtual Machine (CVM) program, which:

  • Specifies which hops need to happen
  • Specifies which calls to virtual wallet need to occur
  • If a solution has multiple hops - routed back to Centauri chain
  • Ex. Transferring to a CEX
    • Problem defined as location to send funds to
    • User funds transferred to virtual wallet
    • CVM instruction set defines the necessary hops to the required network able to accept the assets
    • Transfers occur over IBC

This is depicted below: CVM

Verifiable Settlement

Settlement of transactions resolving user intents must be verifiable. We also believe that these transactions must be partial block aware; To improve cross-domain censorship-resistance and enforce searcher conditioning for cross-domain transactions, partial block auctions are a must.

Examples of this can be seen in Cosmos, but Ethereum requires additional work regarding commitments to allow for a differentiation between top-of-block and rest-of-block.
