Up to this point, we've delved into Gateway, understanding its functionality and security considerations. Now, let's shift our focus to what can be created using Gateway. We'll discuss potential use-cases for Gateway, aiming to uncover its full potential. After that, we'll explore how to perform essential operations with Gateway for your DApp considering the fee structure and will guide Cosmos developers on integrating their Appchains with Gateway.
Potential Use-Cases:Before we delve into the use-cases, it's essential to acknowledge that as more Appchains integrate with Gateway, we will uncover a growing array of potential use-cases.
IBC-Native Assets: Gateway can be used to create IBC-Native version of assets by deploying Cosmwasm contracts on Gateway. This can be assets like native USDC, native DAI etc.
Decentralized Identity and Authentication:Developers can leverage Gateway to build decentralized identity and authentication solutions that work across multiple Cosmos Appchains. This ensures secure and privacy-focused identity verification for various applications.
Cross-Chain Data Oracles: Developers can build cross-chain data oracles on Gateway, providing smart contracts and applications access to real-time data from multiple sources. This enhances the reliability and functionality of DeFi and decentralized applications.
Interchain Staking:Users can stake assets bridged through Gateway on Osmosis, participating in network security and governance activities while earning staking rewards.
These are just a few examples of the many potential use-cases to kickstart your journey with Gateway. The possibilities are vast, and now, let's explore how you can begin building with Gateway.
Integrating Wormhole Gateway with your dApp:
Integration with Wormhole Gateway can be accomplished with a few lines of code
Transfers from an External Chain to any supported Cosmos Chain, see Into Cosmos
Transfers from any supported Cosmos Chain to an External Chain, see Out of Comsos
Transfers between any supported Cosmos Chains, see Between Cosmos Chains
Fee Structure:
Gateway, fees are designed to be minimal. Currently, the primary cost to consider is the source chain gas fee, especially when transferring assets from blockchains. Here is a breakdown of the fees you may encounter when using Gateway:
Fee Required:
Source Chain Gas: This pertains to the gas fees incurred on the source chain, such as Ethereum. Users must cover these fees when initiating transactions.
Relayer Fee [Source Chain → Gateway]: As of now, the cost for processing a Wormhole message from the source chain to Gateway is zero. However, it's worth noting that this fee structure might evolve in the future.
Destination Chain Gas [Non-Cosmos]: Gas fees on a destination chain (e.g., Ethereum) must be covered by either the relayer or, the user
Fee Not Required:
Gateway: Gateway does not have token-priced metering or require gas fees to be paid by the user
Relayer Fee [Gateway → Cosmos]: Relayers are not incentivized by user fees.
Destination Chain [Cosmos]: The processing cost on the destination chain within the Cosmos ecosystem is covered by IBC relayers.
