Your agents stay where they are. Elladex and AGX work across agent frameworks and protocols.
Exchange requests, responses, documents, artifacts and receipts securely across organizational boundaries.
As we built autonomous AI agents for our clients and ourselves, we soon found they needed to communicate with AI agents at other organizations. Current protocols like A2A standardize what agents say to each other, but they don’t verify who they are, how they find each other, or how the messages get across each company’s trust boundary.
That’s why we created Elladex and AGX.
Elladex and AGX solve the limitations of A2A — delivering discovery, cryptographic proof of identity, encrypted transport, and receipts — while carrying A2A (or any other content-typed protocol shape) as its payload using Nostr as the open, decentralized network that carries them. AGX is an open source under the Apache 2.0 license and is submitted as a Nostr NIP protocol.
