The Symbiotic Relay SDK is the trust layer for data and computation.
It turns any data, computation, or event into money backed, stake secured attestations that settle on chain and trigger programmable outcomes. With Relay you:
Relay is the missing link between computation and consensus, the universal economically secured proof layer for the modular internet.
Large validator sets became prohibitively expensive to verify across chains. Networks with hundreds of operators were facing millions per year in verification costs on Ethereum alone. At the same time, protocols that wanted to run multichain were pushed into Proof-of-Authority models because staking data was not available cross-chain in a usable, verifiable way.
Application Layer
Any app or service performs a task: fetching prices, running an AI model, or monitoring transactions.
Relay Network
Operators in the Relay Network generate cryptographic attestations that confirm the task was executed as claimed.
Relay Settlement
These attestations are verified on-chain using validator stakes within Symbiotic Core contracts.
On-Chain Action
Once verified, the attestation can trigger any programmable outcome:

The Relay turns any external workload into a verifiable on-chain action. Networks plug in a lightweight client, inherit stake-backed security with slashing, and use a single attestation flow that works across chains and use cases. The result is less code to maintain, clearer guarantees, and a portable integration you can reuse everywhere.
