π Glossary: Signal Service
Signal Service lets UniFi appchains access and use Ethereum L1 data within the same slot, without relying on third party bridges.
Without Signal Service, L2 apps accessing L1 state depend on bridges with off chain verifiers reading RPC nodes that can be manipulated. Signal Service removes that dependency. L1 signals are registered, imported into L2, and used immediately. Verification happens through contract calls, not trusted intermediaries.
This enables same slot deposits, fresh L1 oracle reads, and the L1 to L2 leg of synchronous composability on UniFi.
Signal Service handles L1 to L2. Proof generated bridging handles L2 to L1. Based sequencing adds timing and execution guarantees across both. π‘
