# abort used to enable the panic handler that hands a nice error message back to the host.
# The feature is now deprecated and the panic handler is always enabled.
abort = []
std = []
# 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)
iterator = []
# 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
staking = []
# stargate enables stargate-dependent messages and queries, like raw protobuf messages
# as well as ibc-related functionality
stargate = []
# This feature makes `BankQuery::Supply` available for the contract to call, but requires
# the host blockchain to run CosmWasm `1.1.0` or higher.
cosmwasm_1_1 = []
# This feature makes `GovMsg::VoteWeighted` available for the contract to call, but requires
# the host blockchain to run CosmWasm `1.2.0` or higher.
cosmwasm_1_2 = ["cosmwasm_1_1"]
# This feature makes `BankQuery::DenomMetadata` available for the contract to call, but requires
# the host blockchain to run CosmWasm `1.3.0` or higher.
cosmwasm_1_3 = ["cosmwasm_1_2"]
# Together with the `iterator` feature this enables additional imports for more
# efficient iteration over DB keys or values.
# It also makes `DistributionQuery::{DelegationRewards, DelegationTotalRewards, DelegatorValidators}`
# available for the contract to call.
# It requires the host blockchain to run CosmWasm `1.4.0` or higher.
cosmwasm_1_4 = ["cosmwasm_1_3"]
# This enables functionality that is only available on 2.0 chains.
# It adds `CosmosMsg::Any`, replacing `CosmosMsg::Stargate`. It also adds `QueryRequest::Grpc`.
cosmwasm_2_0 = ["cosmwasm_1_4"]
# This enables functionality that is only available on 2.1 chains.
# It adds verification and key recovery for the secp256r1 elliptic curve.
cosmwasm_2_1 = ["cosmwasm_2_0"]
# This enables functionality that is only available on 2.2 chains.
# It adds `IbcMsg::PayPacketFee` and `IbcMsg::PayPacketFeeAsync`.
