# Add Referenda Precompile
This PR introduces the referenda precompile from Moonbeam to enable
governance functionality through EVM calls.
## Changes Made
- Added `operator/precompiles/referenda/` with complete implementation
- Updated all runtime configs (mainnet, stagenet, testnet) to include
the referenda precompile
- Adapted track processing logic to work with DataHaven's runtime
configuration
- Adapted tests and mock according to our runtime

## Add Preimage Precompile
This PR integrates the Preimage precompile from Moonbeam into the
DataHaven runtime across all three environments (mainnet, stagenet,
testnet).
**Key Changes:**
- Added Preimage precompile implementation at address `2067` in all
runtime configurations
- Updated precompile sets in mainnet, stagenet, and testnet runtimes
- Updated `is_governance_precompile()` for the Preimage precompile
## Add Conviction Voting Precompile
This PR introduces a new EVM precompile for conviction voting
functionality, enabling smart contracts to interact with the Substrate
conviction voting pallet.
### Key Changes
- **New Precompile**: Added `ConvictionVotingPrecompile` at address
`0x0000000000000000000000000000000000000812` (2066)
- **Solidity Interface**: Complete Solidity interface
(`ConvictionVoting.sol`) with all conviction voting operations
- **Runtime Integration**: Integrated precompile across all runtime
configurations (mainnet, testnet, stagenet)
- **Comprehensive Testing**: Inherits test suite from Moonbeam
### Features
- Vote casting with different conviction levels (None, Locked1x-6x)
- Vote delegation and undelegation
- Poll management and tallying
- Support for all conviction voting pallet operations

## Add Collective Precompile
Adds the pallet collective precompile to `mainnet`, `stagenet`, and
`testnet` according to Moonbeam's configuration.
### Changes:
- Added `pallet-evm-precompile-collective` dependency to workspace
- Configured collective precompile at address `2064` using
`TreasuryCouncilInstanc`
- Configured collective precompile at address `2068` using
`TechnicalCommitteeInstance`
The precompile provides EVM access to collective governance
functionality including proposal execution, voting, and membership
management.

## Add Identity Precompile
Adds the pallet Identity precompile to `mainnet`, `stagenet`, and
`testnet` according to Moonbeam's configuration.
### Changes:
- Added `pallet-evm-precompile-identity` dependency to workspace
- Added and configured at address `2072` for all runtimes
The precompile provides a Solidity interface access to the Substrate
Identity pallet functionality.

Incorporate `pallet-evm-precompile-file-system` into `stagenet`,
`testnet` and `mainnet`.

## Summary
This PR adds Moonbeam's Batch precompile to DataHaven, enabling
efficient batching of multiple EVM transactions in a single call. This
implementation follows Moonbeam's exact architecture and provides
significant gas savings for batch operations.
## Key Features
### Batch Precompile Functions
- **`batchSome(address[], uint256[], bytes[], uint64[])`**: Execute
multiple calls, continuing on failures
- **`batchSomeUntilFailure(address[], uint256[], bytes[], uint64[])`**:
Execute calls until first failure
- **`batchAll(address[], uint256[], bytes[], uint64[])`**: Execute all
calls, reverting if any fail
### Technical Implementation
- **Address**: `0x0808` (2056 in decimal)
- **Access Control**: Restricted nesting with `SubcallWithMaxNesting<2>`
- **Self-recursion**: Only the Batch precompile can call itself
(`OnlyFrom<AddressU64<2056>>`)
- **Gas Management**: Proper gas estimation and refund handling
- **Error Handling**: Comprehensive revert reasons and event logging
Depends on #137

## Summary
This PR implements a comprehensive EVM precompile registry system for
DataHaven, following Moonbeam's exact architecture and patterns. The
implementation includes:
- **Registry Precompile**: A new precompile at address `0x0815` (2069)
that manages and queries available precompiles
- **Core Ethereum Precompiles**: Standard Ethereum precompiles
(ECRecover, SHA256, RIPEMD160, Identity, ModExp, BN128Add, BN128Mul,
BN128Pairing, Blake2F, SHA3FIPS)
- **Modular Architecture**: Clean separation following Moonbeam's
structure with dedicated precompile modules per runtime
## Key Features
### Registry Precompile Functions
- `isPrecompile(address)`: Check if an address corresponds to any
precompile (active or inactive)
- `isActivePrecompile(address)`: Check if a precompile is currently
active in the runtime
- `updateAccountCode(address)`: Insert dummy EVM bytecode for Solidity
compatibility
### Runtime Integration
- Integrated across all three runtimes (testnet, stagenet, mainnet)
- Uses Moonbeam's `PrecompileSetBuilder` pattern for composable
precompile management
- Proper gas accounting with database read/write operations
- Access control through `CallableByContract` and `CallableByPrecompile`
traits
