  • Improved Cross-Chain Composability: Execute EVM swaps immediately following a Eureka cross-chain transfer, enabling more sophisticated multi-step routes.

  • Enhanced Fee Transparency: Fees associated with Eureka operations are now clearly displayed within the estimated_fees array in API responses from the /v2/fungible/route endpoint, providing better cost predictability. For example:

    "estimated_fees": [
  {
    "fee_type": "SMART_RELAY",
    "bridge_id": "EUREKA",
    "amount": "76099736314413",
    "usd_amount": "0.20",
    "origin_asset": {
      "denom": "0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2",
      "chain_id": "1",
      "symbol": "WETH",
      "name": "Wrapped Ether"
      // ... other asset details (like decimals, logo_uri etc.)
    }
  }
]

    (See API Docs for full response structures from the /v2/fungible/route endpoint.)

  • LayerZero and Stargate Integration: Expanded cross-chain capabilities with the integration of LayerZero and Stargate protocols. This integration adds support for a wide variety of new assets, including USDT, USDe, and ZRO.

    Usage:

    • REST API: Include "layer_zero" and/or "stargate" in the experimental_features array in your POST request to /v2/fungible/route.

      {
  "source_asset_denom": "uatom",
  "source_asset_chain_id": "cosmoshub-4",
  "dest_asset_denom": "uusdc",
  "dest_asset_chain_id": "noble-1",
  "amount_in": "1000000",
  "experimental_features": ["layer_zero", "stargate"]
}

    • Client Library: Add these features to the experimentalFeatures parameter.

      import { route } from '@skip-go/client';

const response = await route({
  sourceAssetDenom: "uatom",
  sourceAssetChainId: "cosmoshub-4",
  destAssetDenom: "uusdc",
  destAssetChainId: "noble-1",
  amountIn: "1000000",
  experimentalFeatures: ["layer_zero", "stargate"]
});

    • Widget Integration: Add LayerZero and Stargate to the experimentalFeatures array in the routeConfig prop of the Skip Widget component.

      import { Widget } from '@skip-go/widget';

<Widget
  routeConfig={{
    experimentalFeatures: ["layer_zero", "stargate"]
  }}
/>

​
Status Endpoint Enhancement (Late May)

  • Transaction Timestamp Information: Added on_chain_at field to individual transaction detail objects (such as send_tx, receive_tx, acknowledge_tx, execute_tx) found within the specific transfer type objects (e.g., ibc_transfer, cctp_transfer, axelar_transfer) in the status endpoint response. This field provides RFC3339 formatted UTC timestamps of when each specific transaction landed on its respective chain.

​
April 2025

  • Eureka Protocol Enhancements:
    • Native token wrapping (e.g., ETH to WETH) is now supported within Eureka cross-chain transfers, with improved fee handling for routes involving native ETH.
    • Eureka Protocol now officially supports transfers to and from Ethereum Mainnet and the Cosmos Hub.
