What it is
A narrative spike pairs a large Farcaster channel with a chain-level liquidity move that already cleared the Signal threshold. It is attention plus on-chain movement, not a sentiment score.
Why it matters
Markets move through both capital and story. A chain can deepen quietly, or a crowd can talk loudly with no depth behind it. The interesting read is when a large public harbor and the chain's own liquidity move at the same time.
How we read it
We use Farcaster's public channel directory to find where crypto conversation gathers, then match channel ids and names to chain slugs. A Signal only fires when the matched chain already has a weekly liquidity shift large enough to be read honestly.
What it cannot tell you
Without a Neynar key this is not a live cast velocity model. It is a keyless audience map plus chain movement. When Neynar is configured, the narrative pages add richer cast reads, but the Signal itself stays grounded in the sourced chain move.
