BTR is an adaptive multi-asset AMM: pools quote from external keeper marks, shape spreads from their own inventory and coverage, and protect LPs from [impermanent loss](/docs/glossary#impermanent-loss-il) by construction rather than by subsidy. The [docs](/docs/overview) carry the formal spec; this blog carries everything that doesn't fit a spec page yet.

## How often

Rarely, and never to fill a schedule. A post goes up when there is something
worth the read: how BTR works, an internals piece on AMM mechanics, a problem
we hit and what it cost us to solve, what is next on the road, an integration
going live, or a specification and the implementation details underneath it.
Silence here means we are building, not that we ran out of things to say.

## What belongs here

- **Design notes** - why a mechanism looks the way it does. The narrative behind [spread & fees](/docs/1-1-4-spread-fees), [depeg gates](/docs/3-2-1-flow-guards), or [anchor-path routing](/docs/1-1-3-anchor-path-pricing) before it hardens into the docs.
- **Deployment write-ups** - what shipped on [Arc](/docs/2-overview), what changed in the contract roster, what the pool composition is.
- **Research in progress** - liquidity-curve studies, oracle-latency measurements, LVR comparisons. Anything here that survives scrutiny graduates into the docs.
