This pallet provides the following functionality: +//! +//! - Pallet hooks allowing [`pallet-assets`] to know the frozen balance for an account on a given +//! asset (see [`pallet_assets::FrozenBalance`]). +//! - An implementation of +//! [`fungibles::freeze::Inspect`](frame_support::traits::fungibles::freeze::Inspect) and +//! [`fungibles::freeze::Mutate`](frame_support::traits::fungibles::freeze::Mutate), allowing +//! other pallets to manage freezes for the `pallet-assets` assets. + +#![cfg_attr(not(feature = "std"), no_std)] + +use frame_support::{ + pallet_prelude::*, + traits::{tokens::IdAmount, VariantCount, VariantCountOf}, + BoundedVec, +}; +use frame_system::pallet_prelude::BlockNumberFor; +use sp_runtime::{ + traits::{Saturating, Zero}, + BoundedSlice, +}; + +pub use pallet::*; + +#[cfg(test)] +mod mock; +#[cfg(test)] +mod tests; + +mod impls; + +#[frame_support::pallet] +pub mod pallet { + use super::*; + + #[pallet::config(with_default)] + pub trait Config: frame_system::Config + pallet_assets::Config { + /// The overarching freeze reason. + #[pallet::no_default_bounds] + type RuntimeFreezeReason: Parameter + Member + MaxEncodedLen + Copy + VariantCount; + + /// The overarching event type. + #[pallet::no_default_bounds] + type RuntimeEvent: From> + + IsType<::RuntimeEvent>; + } + + #[pallet::error] + pub enum Error { + /// Number of freezes on an account would exceed `MaxFreezes`. + TooManyFreezes, + } + + #[pallet::pallet] + pub struct Pallet(_); + + #[pallet::event] + #[pallet::generate_deposit(pub(super) fn deposit_event)] + pub enum Event, I: 'static = ()> { + // `who`s frozen balance was increased by `amount`. + Frozen { who: T::AccountId, asset_id: T::AssetId, amount: T::Balance }, + // `who`s frozen balance was decreased by `amount`. + Thawed { who: T::AccountId, asset_id: T::AssetId, amount: T::Balance }, + } + + /// A map that stores freezes applied on an account for a given AssetId. + #[pallet::storage] + pub(super) type Freezes, I: 'static = ()> = StorageDoubleMap< + _, + Blake2_128Concat, + T::AssetId, + Blake2_128Concat, + T::AccountId, + BoundedVec< + IdAmount, + VariantCountOf, + >, + ValueQuery, + >; + + /// A map that stores the current total frozen balance for every account on a given AssetId. + #[pallet::storage] + pub(super) type FrozenBalances, I: 'static = ()> = StorageDoubleMap< + _, + Blake2_128Concat, + T::AssetId, + Blake2_128Concat, + T::AccountId, + T::Balance, + >; + + #[pallet::hooks] + impl, I: 'static> Hooks> for Pallet { + #[cfg(feature = "try-runtime")] + fn try_state(_: BlockNumberFor) -> Result<(), sp_runtime::TryRuntimeError> { + Self::do_try_state() + } + } +} + +impl, I: 'static> Pallet { + fn update_freezes( + asset: T::AssetId, + who: &T::AccountId, + freezes: BoundedSlice< + IdAmount, + VariantCountOf, + >, + ) -> DispatchResult { + let prev_frozen = FrozenBalances::::get(asset.clone(), who).unwrap_or_default(); + let after_frozen = freezes.into_iter().map(|f| f.amount).max().unwrap_or_else(Zero::zero); + FrozenBalances::::set(asset.clone(), who, Some(after_frozen)); + if freezes.is_empty() { + Freezes::::remove(asset.clone(), who); + FrozenBalances::::remove(asset.clone(), who); + } else { + Freezes::::insert(asset.clone(), who, freezes); + } + if prev_frozen > after_frozen { + let amount = prev_frozen.saturating_sub(after_frozen); + Self::deposit_event(Event::Thawed { asset_id: asset, who: who.clone(), amount }); + } else if after_frozen > prev_frozen { + let amount = after_frozen.saturating_sub(prev_frozen); + Self::deposit_event(Event::Frozen { asset_id: asset, who: who.clone(), amount }); + } + Ok(()) + } + + #[cfg(any(test, feature = "try-runtime"))] + fn do_try_state() -> Result<(), sp_runtime::TryRuntimeError> { + for (asset, who, _) in FrozenBalances::::iter() { + let max_frozen_amount = + Freezes::::get(asset.clone(), who.clone()).iter().map(|l| l.amount).max(); + + frame_support::ensure!( + FrozenBalances::::get(asset, who) == max_frozen_amount, + "The `FrozenAmount` is not equal to the maximum amount in `Freezes` for (`asset`, `who`)" + ); + } + + Ok(()) + } +} diff --git a/substrate/frame/assets-freezer/src/mock.rs b/substrate/frame/assets-freezer/src/mock.rs new file mode 100644 index 000000000000..b4e8c857fba4 --- /dev/null +++ b/substrate/frame/assets-freezer/src/mock.rs @@ -0,0 +1,154 @@ +// This file is part of Substrate. + +// Copyright (C) Parity Technologies (UK) Ltd. +// SPDX-License-Identifier: Apache-2.0 + +// Licensed under the Apache License, Version 2.0 (the "License"); +// you may not use this file except in compliance with the License. +// You may obtain a copy of the License at +// +// http://www.apache.org/licenses/LICENSE-2.0 +// +// Unless required by applicable law or agreed to in writing, software +// distributed under the License is distributed on an "AS IS" BASIS, +// WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. +// See the License for the specific language governing permissions and +// limitations under the License. + +//!
