DEX Pallet
Custom DEX pallet using the Polkadot SDK based of UniswapV2 implementation.
Disclaimer
This code has not been audited. Use at your own risk.
Usage
Configuring pallet-dex v2 to a solo-chain or a parachain is a simple process.
First, add the following to your Cargo.toml
:
pallet-dex-v2 = { version = "0.0.3", default-features = false}
# if you don't use pallet-assets in your runtime before, you need to add it to your runtime
pallet-assets = { version = "32.0.0", default-features = false }
Then, add the following to your runtime's lib.rs
:
pub use pallet_dex_v2 as dex;
// declare pallet id for dex
parameter_types! {
// pallet ID
pub const DexPallet: PalletId = PalletId(*b"DCitadel");
}
// declare types used in asset pallet
parameter_types! {
pub const AssetDeposit: Balance = 100;
pub const ApprovalDeposit: Balance = 1;
pub const StringLimit: u32 = 50;
pub const MetadataDepositBase: Balance = 10;
pub const MetadataDepositPerByte: Balance = 1;
}
/// Configure the assets pallet
impl pallet_assets::Config for Runtime {
type RuntimeEvent = RuntimeEvent;
type Balance = u128;
type AssetId = u32;
type AssetIdParameter = codec::Compact<u32>;
type Currency = Balances;
type CreateOrigin = AsEnsureOriginWithArg<EnsureSigned<AccountId>>;
type ForceOrigin = EnsureRoot<AccountId>;
type AssetDeposit = AssetDeposit;
type AssetAccountDeposit = ConstU128<1>;
type MetadataDepositBase = MetadataDepositBase;
type MetadataDepositPerByte = MetadataDepositPerByte;
type ApprovalDeposit = ApprovalDeposit;
type StringLimit = StringLimit;
type Freezer = ();
type Extra = ();
type WeightInfo = pallet_assets::weights::SubstrateWeight<Runtime>;
type RemoveItemsLimit = ConstU32<1000>;
type CallbackHandle = ();
#[cfg(feature = "runtime-benchmarks")]
type BenchmarkHelper = ();
}
/// Configure the dex pallet
impl pallet_dex::Config for Runtime {
type RuntimeEvent = RuntimeEvent;
type NativeBalance = Balances;
type Fungibles = Assets;
type PalletId = DexPallet;
}
