## 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)

## Summary
- Fixed `ProxyType` enum in the Solidity Proxy precompile interface to
match the runtime definition
- Removed non-existent `AuthorMapping` variant
- Added missing `SudoOnly` variant
## Problem
The Solidity interface in `Proxy.sol` had incorrect `ProxyType` enum
values that didn't match the runtime definition:
| Index | Runtime (Correct) | Solidity (Was) |
|-------|------------------|----------------|
| 0 | Any | Any |
| 1 | NonTransfer | NonTransfer |
| 2 | Governance | Governance |
| 3 | Staking | Staking |
| 4 | CancelProxy | CancelProxy |
| 5 | Balances | Balances |
| 6 | **IdentityJudgement** | **AuthorMapping** ❌ |
| 7 | **SudoOnly** | **IdentityJudgement** ❌ |
This mismatch would cause EVM users calling the Proxy precompile with
`IdentityJudgement` (index 7 in Solidity) to actually get `SudoOnly`
behavior, and `AuthorMapping` (index 6) would fail to decode entirely
since it doesn't exist in the runtime.
## Solution
Updated the Solidity enum to match the runtime:
```solidity
enum ProxyType {
Any,
NonTransfer,
Governance,
Staking,
CancelProxy,
Balances,
IdentityJudgement,
SudoOnly
}
```
## ⚠️ Breaking Changes ⚠️
- **`ProxyType.AuthorMapping` removed**: This variant never existed in
the runtime and would fail to decode.
- **`ProxyType.IdentityJudgement` index changed**: Moved from index 7 to
index 6. Solidity code using `ProxyType.IdentityJudgement` will now work
correctly (previously it mapped to `SudoOnly` in the runtime)
- **`ProxyType.SudoOnly` added**: New variant at index 7 for proxies
that can only execute Sudo pallet calls
## Test plan
- [x] Proxy precompile tests pass (32/32)
- [x] Mainnet runtime proxy tests pass (22/22)
- [x] Governance proxy tests pass (6/6)
- [x] Verified `InstanceFilter<RuntimeCall>` implementation handles all
8 variants correctly
- [x] Verified `EvmProxyCallFilter` implementation handles all 8
variants correctly

Set `GasLimitPovSizeRatio` to 0 across all runtime environments
(mainnet, stagenet, testnet) since DataHaven operates as a solo chain
and doesn't need to account for Proof-of-Validity size constraints that
parachains require.
## ⚠️ Breaking Changes ⚠️
- `GasLimitPovSizeRatio` is now set to 0 across all runtimes
- Gas calculations will no longer account for POV size constraints
## Summary
- rename the FRAME alias for `pallet_evm` from `Evm` to `EVM` across the
mainnet, stagenet, and testnet runtimes
- adjust benchmarks, configuration modules, genesis builders, and
runtime tests to rely on the new alias
- keep precompile genesis setup and proxy/precompile tests aligned with
the updated names
## Context
Frontier’s `StorageOverrideHandler` (see
`fc_storage::StorageQuerier::account_code`) reads contract bytecode from
`pallet_evm::AccountCodes` using the constant `PALLET_EVM = b"EVM"` to
build the storage key:
`twox_128("EVM") ++ twox_128("AccountCodes") ++ …`
Our runtimes exported `pallet_evm` as `Evm`, so substrate stored
bytecode under the *camel-cased* prefix (`twox_128("Evm")`). Every call
that ultimately hits the storage override—including `eth_getCode`,
`eth_call`, and state queries during replay—therefore failed to locate
code for *any* account (deployed contracts and precompiles alike).
Renaming the alias to `EVM` realigns the storage prefix with Frontier’s
expectations so the override layers can pull bytecode correctly.
## Testing
- `cargo check -p datahaven-node`
- `cargo build --release -p datahaven-node`
- `eth_getCode 0x0000000000000000000000000000000000000802` → returns
`0x60006000fd`
## Storage Migration
Renaming a pallet alias changes the storage prefix for all pallet data.
Without migration, existing EVM data (smart contracts, account codes,
storage) would become inaccessible.
**Migration details:**
- **Type**: Multi-Block Migration (MBM)
- **Storage migrated**: `AccountCodes`, `AccountCodesMetadata`,
`AccountStorages`
- **Migration ID**: `datahaven-evm-mbm` (version 0 → 1)
**Testing the migration:**
```bash
# Build runtime with try-runtime
cargo build --release --features try-runtime -p
datahaven-stagenet-runtime
# Test against stagenet
try-runtime \
--runtime
./target/release/wbuild/datahaven-stagenet-runtime/datahaven_stagenet_runtime.wasm
\
on-runtime-upgrade \
--blocktime 6000 \
--checks all \
--disable-spec-version-check \
live --uri wss://dh-validator-0.datahaven-kt.xyz
```
Test results from stagenet:
- ✅ Migration completes in 1 block
- ✅ PoV size: ~5.3 KB
- ✅ Weight consumption: <0.1% of block capacity
- ✅ All 39 keys successfully migrated
## ⚠️ Breaking Changes ⚠️
If you are manually computing storage keys for the EVM pallet (e.g., directly querying chain state), you must update your code to use the new storage prefix:
- Old prefix: twox128("Evm") = 0x8b90cb...
- New prefix: twox128("EVM") = 0x6a5e91...
All EVM-facing interfaces remain unchanged.
