# AliasCollision (/docs/errors/chain/AliasCollision)

The derived EVM alias is already bound to another account. This descriptor cannot be registered safely; create a new hashed wallet and use its new descriptor.

Declared by the `HashedAccounts` pallet; it classifies to the semantic code [`already_exists`](/docs/errors/already-exists).

Declared at [`pallets/hashed-accounts/src/lib.rs#L277`](/code/pallets/hashed-accounts/src/lib.rs#L277).

## Remediation [#remediation]

The object or state already exists; treat the goal as met or pick a different target

The same explanation is available in the terminal: `btcli explain AliasCollision`.
