The Symbiotic steaking protocol team has introduced a middleware SDK called Symbiotic Relay. This solution allows any network to utilize blocked assets (steak) across ecosystems to validate consensus or quorum results without an intermediary.

Symbiotic Relay provides interoperability and composability for all networks supported by the protocol, the developers said. This opens the door to bridges, computation tiers, oracles and rollups without reliance on multi-signature, delegated schemes or centralized intermediaries.

In a comment to Incrypted, Symbiotic co-founder Misha Putiatin explained the mechanism of the solution as follows:

“Relay introduces a universal coordination layer that abstracts away the complexity of subject consensus mechanisms. Rather than requiring each chain to ‘speak’ the same ‘consensus language,’ Relay allows protocols to secure decisions using stacked capital in one chain and verify those decisions in others, even if they run on completely different consensus mechanisms.”

According to him, the solution architecture is based on three main components: onchain stacking modules, offchain signature aggregation using an sidecar network, and onchain contracts for finalization.

“The biggest challenge was to create a mechanism that allows steak-backed decisions to be made and validated across execution environments – without having to deploy new sets of validators or rely on trusted intermediaries like multisig addresses. This required designing a system capable of proving results in an onchain-based way with minimal trust,” he said.

As the team noted, Symbiotic Relay enables a new class of applications whose security will be ensured by the entire cryptocurrency ecosystem.

It also eliminates trust gaps and fragmentation when dealing with dApps that support different networks. Users no longer have to worry about which network they have locked assets on. Symbiotic Relay makes composability crypto-economically verifiable, the developers emphasized.

“Before, building a reliable crosschain infrastructure required expensive custom development or reliance on centralized relays. Relay solves this problem. It makes verifiable, steak-based coordination between networks as simple as a plugin – without trust assumptions or permissions, ensuring secure results across ecosystems,” said Symbiotic co-founder Algis Ievlev.

The new software package brings together the reliability of the bitcoin network, the expressiveness of Ethereum, and the performance of Solana, applying the embedded capital as a common, verifiable source of security within the Symbiotic layer.

At the end of April 2025, we reported that the project had closed a $29 million Series A funding round, with the protocol team noting that it was the creation of Relay that was the focus of the funding.

The developers noted that the solution is already being tested by various teams behind high-finalization rate rollups, oracles, bridges, and decentralized insurance layers for which it is important to capture results across multiple networks at once without sacrificing speed or security.

As the project team noted, Relay provides the potential to integrate dozens of new networks and modular systems, reinforcing the protocol’s role as a cryptoeconomic coordination layer for an open, interconnected blockchain world.
