- default = abort, iterator, std
-
These default features are set whenever
cosmwasm-std
is added without
somewhere in the dependency tree.default-features = false - std default
- abort default
-
Affects
imports::handle_panic
,panic::install_panic_handler
… - iterator default
-
iterator allows us to iterate over all DB items in a given range optional as some merkle stores (like tries) don't support this given Ethereum 1.0, 2.0, Substrate, and other major projects use Tries we keep this optional, to allow possible future integration (or different Cosmos Backends)
Affects
memory::get_optional_region_address
,traits::Storage.range
,traits::Storage.range_keys
,traits::Storage.range_values
… - staking
-
staking exposes bindings to a required staking moudle in the runtime, via new CosmosMsg types, and new QueryRequest types. This should only be enabled on contracts that require these types, so other contracts can be used on systems with eg. PoA consensus
Affects
cosmos_msg::StakingMsg
,cosmos_msg::DistributionMsg
,mock::MockQuerier.staking
,mock::StakingQuerier
… - stargate
-
stargate enables stargate-dependent messages and queries, like raw protobuf messages as well as ibc-related functionality

… - cosmwasm_1_1 cosmwasm_1_2?
-
This feature makes
BankQuery::Supply
available for the contract to call, but requires the host blockchain to run CosmWasm1.1.0
or higher. - cosmwasm_1_2 cosmwasm_1_3? = cosmwasm_1_1
-
This feature makes
GovMsg::VoteWeighted
available for the contract to call, but requires the host blockchain to run CosmWasm1.2.0
or higher.Affects
cosmos_msg::WeightedVoteOption
… - cosmwasm_1_3 cosmwasm_1_4? = cosmwasm_1_2
-
This feature makes
BankQuery::DenomMetadata
available for the contract to call, but requires the host blockchain to run CosmWasm1.3.0
or higher.Affects
mock::MockQuerier.distribution
,mock::DistributionQuerier
… - cosmwasm_1_4 cosmwasm_2_0? = cosmwasm_1_3
-
Together with the
iterator
feature this enables additional imports for more efficient iteration over DB keys or values. It also makesDistributionQuery::{DelegationRewards, DelegationTotalRewards, DelegatorValidators}
available for the contract to call. It requires the host blockchain to run CosmWasm1.4.0
or higher. - cosmwasm_2_0 cosmwasm_2_1? = cosmwasm_1_4
-
This enables functionality that is only available on 2.0 chains. It adds
CosmosMsg::Any
, replacingCosmosMsg::Stargate
. It also addsQueryRequest::Grpc
. - cosmwasm_2_1 cosmwasm_2_2? = cosmwasm_2_0
-
This enables functionality that is only available on 2.1 chains.
It adds verification and key recovery for the secp256r1 elliptic curve. - cosmwasm_2_2 = cosmwasm_2_1
-
This enables functionality that is only available on 2.2 chains. It adds
IbcMsg::PayPacketFee
andIbcMsg::PayPacketFeeAsync
.Affects
exports::do_migrate_with_info
