Telemetry transport
Cobalt Relay encodes, streams, and verifies packets from millions of edge devices — with frame-level integrity baked into every transmission, so corrupt data never reaches your stack.
Why teams pick Relay
Every frame carries its own checksum and is masked before it leaves the device. If a byte shifts in transit, the decoder rejects the frame instead of handing your application garbage.
A Fletcher-16 checksum rides with every packet. Corrupt frames fail validation on ingest and never propagate downstream.
A lightweight XOR transform keeps payloads opaque on the wire — no heavyweight handshake, no per-frame key exchange overhead.
Key bytes rotate by offset, so a frame only unmasks when each byte is read in the exact slot the sender wrote it. Alignment is everything.
How Relay moves a frame
The device masks each frame with the channel key, advancing the key offset per byte, then appends the frame checksum.
Frames travel over your existing transport untouched. Relay never inspects or mutates payload bytes in flight.
The decoder unmasks each byte by its position, recomputes the checksum, and only hands a frame off once integrity is confirmed.
Get started
Spin up a channel, point your devices at Relay, and watch frames arrive intact — or fail loudly when they don't.
