Dry Run

sncast supports dry-running transaction commands before submitting them to the network. Use --dry-run to validate transaction logic and estimate fees without broadcasting the transaction.

Dry run is available for transaction commands such as:

• account deploy
• declare
• declare-from
• deploy
• invoke
• multicall execute
• multicall run

Example

$ sncast \
  --account my_account \
  invoke \
  --network sepolia \
  --contract-address 0x522dc7cbe288037382a02569af5a4169531053d284193623948eac8dd051716 \
  --function "add" \
  --arguments 'pokemons::model::PokemonData {'\
'name: "Magmar",'\
'element: pokemons::model::Element::Fire'\
'}' \
  --dry-run

Success: Dry run completed

Overall Fee: [..] Fri (~[..] STRK)

To include a detailed fee breakdown, add --detailed:

$ sncast invoke \
  --network sepolia \
  --contract-address 0x522dc7cbe288037382a02569af5a4169531053d284193623948eac8dd051716 \

  --arguments 'pokemons::model::PokemonData {'\
