Been diving deep into Sign’s architecture this week, and honestly “omni-chain” is the most misused word in Web3 right now.
Everyone slaps it on their deck. Most don’t mean it.
For Sign Protocol, it’s not marketing. It’s a design requirement.
Attestations are only useful if they’re verifiable wherever the verifier is.
A compliance record on Ethereum means nothing if a DeFi protocol on Arbitrum can’t check it in real time.
Sign Protocol is deployed across ETH, Arbitrum, BNB Chain, Base, and more. One schema. One issuance flow.
Verified on any supported chain. SignScan aggregates across all of them, builders don’t specify chains, they just query.
For sovereign deployments it gets even more interesting.
A government CBDC on a private chain and a public stablecoin on a public chain both need to reference the same identity and compliance records.
Cross-chain attestation makes that possible.
That’s why omni-chain actually matters here.
