Cross-Chain Execution

The Multichain Vision​

AI agents should not be siloed. A truly useful autonomous agent needs to interact with the entire crypto economy, regardless of which blockchain the assets or data reside on.

Orbinum Network is designed as a Multichain Coordination Layer. Agents live on Orbinum, where they process intelligence, but they execute actions everywhere.

Universal Gas ($ON)​

One of the biggest friction points in multichain operations is managing gas tokens. An agent trying to act on Ethereum, Solana, and Polygon would traditionally need to hold ETH, SOL, and POL.

Orbinum solves this with Universal Gas Abstraction:

  1. The user/agent pays transaction fees in $ON on Orbinum.
  2. The network's Relayer Protocol handles the conversion and payment of native gas on the destination chain.
  3. The agent never needs to manage balances on target chains.

Architecture​

1. The Agent (On Orbinum)​

The agent's logic, memory, and decision-making process run on Orbinum's Edge Nodes (Miners). The agent decides, for example, "I need to swap USDC for ETH on Uniswap (Ethereum Mainnet)."

2. The Intent Message​

The agent constructs an Intent: a signed message specifying the desired action, the target chain, and the payload (calldata).

3. The Bridge / Messaging Protocol​

Orbinum integrates with established interoperability protocols (such as Hyperlane, LayerZero, or Chainlink CCIP) to securely transmit this intent.

4. The Executor (Relayer)​

A network of Relayers listens for these intents.

  • They pick up the message.
  • They pay the gas on the destination chain (e.g., ETH).
  • They execute the transaction.
  • They submit proof of execution back to Orbinum.

In exchange, the Relayer is reimbursed in $ON (from the fee the agent paid) plus a small premium for their service.

Supported Interactions​

Read Operations (Data)​

Agents can query state from other chains to inform their decisions.

  • Example: "Check the balance of wallet 0x123... on Base."
  • Example: "Read the current price of AAVE from a Chainlink Oracle on Arbitrum."

Write Operations (Transactions)​

Agents can trigger state changes.

  • Example: "Execute a swap on Jupiter (Solana)."
  • Example: "Mint an NFT on Zora."
  • Example: "Bridge assets from Polygon to Optimism."

Security Model​

Cross-chain operations inherit the security of the underlying interoperability protocol used. Orbinum prioritizes protocols with:

  • Decentralized Verification: No single point of failure.
  • Slashing Mechanisms: Penalties for relayers who submit false proofs.
  • Liveness Guarantees: Ensuring messages are delivered.

Example Workflow: The Arbitrage Agent​

  1. Monitor: An Orbinum agent monitors DEX prices on Ethereum and Solana via data feeds.
  2. Analyze: The agent detects a price discrepancy (Arbitrage opportunity).
  3. Decide: The agent decides to buy on Solana and sell on Ethereum.
  4. Execute:
    • It signs a transaction to swap on Solana.
    • It signs a transaction to swap on Ethereum.
    • It pays total fees in $ON.
  5. Relay: Relayers execute both swaps on their respective chains.
  6. Settle: The profit (in stablecoins) is bridged back to the agent's treasury wallet.
