# RootWeightCapExceeded (/docs/errors/chain/RootWeightCapExceeded)

One destination in the `set_root_weights` vector takes a larger share of the basket than the `RootWeightsCap` hyperparameter allows (share = weight / sum of weights; the cap is u16-normalized, so 4096 means 1/16). Spread the vector across more destinations — at the launch cap of 1/16 a basket needs at least 16 — or lower the largest entries. Query `RootWeightsCap[0]` for the live cap. Not enforced while the chain has fewer subnets than the cap demands.

Declared by the `SubtensorModule` pallet; it classifies to the semantic code [`limit_exceeded`](/docs/errors/limit-exceeded).

Declared at [`pallets/subtensor/src/macros/errors.rs#L374`](/code/pallets/subtensor/src/macros/errors.rs#L374).
