## Polkadot upgrade 2503 In this PR, we upgrade form Polkadot SDK 2412 to Polkadot SDK 2503. In order to upgrade the SDK we need to upgrade some dependencies : StorageHub and frontier simultaneously. ## What changes ### Trivial changes * https://github.com/paritytech/polkadot-sdk/pull/7634 -> The new trait is required in all the pallets using scale encoding. * https://github.com/paritytech/polkadot-sdk/pull/7043 -> Remove deprecated `sp-std` and replace with `alloc` or `core`. * https://github.com/paritytech/polkadot-sdk/pull/6140 -> Accurate weight reclaim with frame_system::WeightReclaim ### Breaking changes * https://github.com/paritytech/polkadot-sdk/pull/2072 -> There is a change in `pallet-referenda`. Now, the tracks are retrieved as a list of `Track`s. Also, the names of the tracks might have some trailing null values (`\0`). This means display representation of the tracks' names must be sanitized. * https://github.com/paritytech/polkadot-sdk/pull/5723 -> adds the ability for these pallets to specify their source of the block number. This is useful when these pallets are migrated from the relay chain to a parachain and vice versa. (Not entirely sure it is breaking as it is being marked as backward compatible). * https://github.com/paritytech/polkadot-sdk/pull/6338 -> Update Referenda to Support Block Number Provider ### Notable changes * https://github.com/paritytech/polkadot-sdk/pull/5703 -> Not changes required in the codebase but impact fastSync mode. Should improve testing. * https://github.com/paritytech/polkadot-sdk/pull/5842 -> Removes `libp2p` types in authority-discovery, and replace them with network backend agnostic types from `sc-network-types`. The `sc-network` interface is therefore updated accordingly. ## What changes in Frontier * https://github.com/polkadot-evm/frontier/pull/1693 -> Add support for EIP 7702 which has been enable with Pectra. This EIP add a new field `AuthorizationList` in Ethereum transaction. Changes example : ```rust #[test] fn validate_transaction_fails_on_filtered_call() { ... pallet_evm::Call::<Runtime>::call { source: H160::default(), target: H160::default(), input: Vec::new(), value: sp_core::U256::zero(), gas_limit: 21000, max_fee_per_gas: sp_core::U256::zero(), max_priority_fee_per_gas: Some(sp_core::U256::zero()), nonce: None, access_list: Vec::new(), authorization_list: Vec::new(), } .into(), ``` ## ⚠️ Breaking Changes ⚠️ * Upgrade to Stirage hub v0.5.1 * Support for Ethereum latest upgrade (txs now have the `authoriation_list` for support EIP 7702) --------- Co-authored-by: Steve Degosserie <723552+stiiifff@users.noreply.github.com> Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com> |
