# DuplicateContract (/docs/errors/chain/DuplicateContract)

Instantiation would create a contract at an address already occupied by an existing contract. Check the derived contract address and vary the `salt` argument to obtain a fresh address.

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

## 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 DuplicateContract`.
