# Cross-Chain Execution

> How Omnera executes trades across multiple chains from a single interface.

# Cross-Chain Execution

## Overview

Omnera supports execution across multiple blockchain networks from a single wallet connection. The trader does not need to bridge assets, switch networks, or manage multiple wallet connections. When the execution router identifies the optimal venue for a trade, it handles the cross-chain mechanics transparently.

## Supported Chains

| Chain             | Asset Types                 | Execution                                                  |
| ----------------- | --------------------------- | ---------------------------------------------------------- |
| Solana            | Spot tokens, SPL assets     | Direct liquidity venue and aggregator routing              |
| Ethereum L2s      | Spot tokens, DeFi positions | Bridged execution with atomic settlement                   |
| Additional chains | Expanding                   | See [Roadmap](/roadmap/overview) for upcoming integrations |

## How It Works

When a trader initiates a trade on an asset that resides on a different chain from their primary wallet:

1. **The router evaluates cross-chain paths.** Multiple bridging options may exist. The router selects based on speed, cost, and reliability.
2. **A transaction bundle is constructed.** The bridge operation, the order placement, and any intermediate steps are composed into a single transaction flow.
3. **The trader reviews and signs.** The complete execution path is presented before confirmation. One signature initiates the full sequence.
4. **Atomic settlement.** The trade settles as a single unit. If any step fails, the entire operation reverts.

## Execution Guarantees

**Price protection.** The execution price shown at confirmation is protected by slippage parameters. If market conditions shift beyond the trader's tolerance during settlement, the transaction reverts.

**No intermediate custody.** At no point do funds rest in an Omnera-controlled address. Cross-chain movement uses trustless or minimally-trusted bridge infrastructure.

**Transaction transparency.** Every step in the cross-chain execution is traceable on-chain. The trader receives transaction hashes for each component of the settlement.

<Warning>
  Cross-chain execution depends on the reliability and security of underlying bridge protocols. While Omnera selects routes for optimal safety, bridge risk cannot be fully eliminated. Cross-chain trades may take longer to settle than same-chain execution.
