🛸Interop Verification Module for Message-Based Bridge Protocols

How Does SEDA Power Interoperability Verification?

SEDA plugs into the existing interoperability frameworks providing a decentralized alternative to commonly centralized co-signers that usually manage message attestations. SEDA’s interoperability programs can be used to add a layer of decentralization to any bridge route, resulting in:

  • additional security

  • support for any token, instantly

  • permissionless deployments

  • liveness guarantees*

  • interoperability with any network

  • support for any route

The diagram below outlines an example of the flow of data and actors powering the SEDA IVM. In this framework the SEDA Network is tasked with verification of chain state and message passing from the Origin Network (e.g., Ethereum) to the target network (e.g., Solana). The Interop Program drastically improves the experience for bridge developers by removing the need for building and maintaining the Relayer and attestation piece of the stack, while reducing centralization risk.

A Fully Customizable Stack

The SEDA IVM is a customize framework that is built utilizing the SEDA Oracle Program toolkit. This programmable infrastructure allows providers to:

  • Define what routes are included

  • Define the data sources and RPCs queried

  • Upgrade modules to include new routes and tokens

  • Specify what data on source chains are required

  • Instruct how data is returned for consumption

  • Create a custom replication factor for Overlay Node secret committees

This programmability enhances IVM compatibility across all virtual machines and bridge designs. While limited customization may result in developers opting for default verification, SEDA's day-one configurability is designed to enable any provider to enhance their service with IVMs, supporting all application types. To learn more about the architecture of the SEDA Network please follow along in the SEDA Network Architecture section of our docs.

*Liveness Guarantees - ensure a system will continue to provide data, and that no single centralized entity can shut down or limit access to data. In the case of SEDA, a data request that has been submitted, with the transaction fee paid, will always reach consensus. In this context, “Liveness Guarantee” is a technical term and the term “guarantee” should not be construed as any kind of legal guarantee.
