Siren watches announced dividends and stock splits on chain 4663, then aims to charge the arbitrageur rather than the liquidity provider when a pool’s quoted price falls behind.

Landing page captured for the 2026-09-16 issue.

Field notes

The site focuses on ERC-8056 corporate actions in which effectiveAt() and newUIMultiplier() announce a future discontinuity while balanceOf() remains unchanged. Its watch page says it checks 23 tokens, cross-checks three legs per token, and limits the proposed surcharge to 20%. The page also distinguishes the mechanism from a deployment, noting that merely holding the token does not protect a pool.
