i want to add pallet-contracts into substrate on branch but i faced errro .
i will tell you step by step what i did :
Step One : Add Depency Pallets
pallet-contracts = { version = "4.0.0-dev", default-features = false, git = "https://github.com/paritytech/substrate.git", " branch" = "polkadot-v0.9.35" }
pallet-contracts-primitives = { version = "7.0.0", default-features = false, git = "https://github.com/paritytech/substrate.git", " branch" = "polkadot-v0.9.35" }
pallet-contracts-rpc-runtime-api = { version = "4.0.0-dev", default-features = false, git = "https://github.com/paritytech/substrate.git", " branch" = "polkadot-v0.9.27" }
Step Two : Add Pallets Config
parameter_types! {
pub TombstoneDeposit: Balance = deposit(
1,
<pallet_contracts::Pallet<Runtime>>::contract_info_size()
);
pub DepositPerContract: Balance = TombstoneDeposit::get();
pub const DepositPerStorageByte: Balance = deposit(0, 1);
pub const DepositPerStorageItem: Balance = deposit(1, 0);
pub RentFraction: Perbill = Perbill::from_rational(1u32, 30 * DAYS);
pub const SurchargeReward: Balance = 150 * MILLICENTS;
pub const SignedClaimHandicap: u32 = 2;
pub const MaxValueSize: u32 = 16 * 1024;
// The lazy deletion runs inside on_initialize.
pub DeletionWeightLimit: Weight = AVERAGE_ON_INITIALIZE_RATIO *
BlockWeights::get().max_block;
// The weight needed for decoding the queue should be less or equal than a fifth
// of the overall weight dedicated to the lazy deletion.
pub DeletionQueueDepth: u32 = ((DeletionWeightLimit::get() / (
<Runtime as pallet_contracts::Config>::WeightInfo::on_initialize_per_queue_item(1) -
<Runtime as pallet_contracts::Config>::WeightInfo::on_initialize_per_queue_item(0)
)) / 5) as u32;
pub Schedule: pallet_contracts::Schedule<Runtime> = Default::default();
}
impl pallet_contracts::Config for Runtime {
type Time = Timestamp;
type Randomness = RandomnessCollectiveFlip;
type Currency = Balances;
type Event = Event;
type RentPayment = ();
type SignedClaimHandicap = SignedClaimHandicap;
type TombstoneDeposit = TombstoneDeposit;
type DepositPerContract = DepositPerContract;
type DepositPerStorageByte = DepositPerStorageByte;
type DepositPerStorageItem = DepositPerStorageItem;
type RentFraction = RentFraction;
type SurchargeReward = SurchargeReward;
type WeightPrice = pallet_transaction_payment::Module<Self>;
type WeightInfo = pallet_contracts::weights::SubstrateWeight<Self>;
type ChainExtension = ();
type DeletionQueueDepth = DeletionQueueDepth;
type DeletionWeightLimit = DeletionWeightLimit;
type Call = Call;
/// The safest default is to allow no calls at all.
///
/// Runtimes should whitelist dispatchables that are allowed to be called from contracts
/// and make sure they are stable. Dispatchables exposed to contracts are not allowed to
/// change because that would break already deployed contracts. The `Call` structure itself
/// is not allowed to change the indices of existing pallets, too.
type CallFilter = Nothing;
type Schedule = Schedule;
type CallStack = [pallet_contracts::Frame<Self>; 31];
}
Step two : Add runtime api
impl pallet_contracts_rpc_runtime_api::ContractsApi<Block, AccountId, Balance, BlockNumber>
for Runtime
{
fn call(
origin: AccountId,
dest: AccountId,
value: Balance,
gas_limit: u64,
input_data: Vec<u8>,
) -> ContractExecResult {
let (exec_result, gas_consumed) =
Contracts::bare_call(origin, dest.into(), value, gas_limit, input_data);
match exec_result {
Ok(v) => ContractExecResult::Success {
flags: v.flags.bits(),
data: v.data,
gas_consumed: gas_consumed,
},
Err(_) => ContractExecResult::Error,
}
}
fn get_storage(
address: AccountId,
key: [u8; 32],
) -> pallet_contracts_primitives::GetStorageResult {
Contracts::get_storage(address, key)
}
fn rent_projection(
address: AccountId,
) -> pallet_contracts_primitives::RentProjectionResult<BlockNumber> {
Contracts::rent_projection(address)
}
}
but it show me this error :
no matching package named `pallet-contracts-rpc-runtime-api` found location searched: https://github.com/paritytech/substrate.git
whats the problem ? how can i solve this problem ?
