## Overview
Implements deterministic weighted-stake-based validator selection in
`DataHavenServiceManager`, building on the era-targeting submitter model
from PR #433. Previously, `buildNewValidatorSetMessage()` forwarded all
registered operators in arbitrary membership order with no stake-based
ranking, meaning high-stake operators could be displaced by lower-stake
ones when downstream caps applied. This PR fixes that by computing a
weighted stake score per operator and selecting the top-32 candidates
before bridging the set to DataHaven.
Spec: `specs/validator-set-selection/validator-set-selection.md`
## Contract Changes (`DataHavenServiceManager.sol`)
**New state:**
- `MAX_ACTIVE_VALIDATORS = 32` — cap on the outbound validator set
- `mapping(IStrategy => uint96) public strategiesAndMultipliers` —
per-strategy weight used in the selection formula
**Updated `buildNewValidatorSetMessage()`:**
1. Fetches allocated stake for all operators × strategies from
`AllocationManager`
2. Computes `weightedStake(op) = Σ(allocatedStake[op][j] ×
multiplier[j])` across all strategies
3. Filters operators with no solochain address mapping or zero weighted
stake
4. Runs a partial selection sort to pick the top `min(candidateCount,
32)` by descending weighted stake; ties broken by lower operator address
(deterministic)
5. Reverts with `EmptyValidatorSet()` if no eligible candidates remain
**Admin API changes:**
- `addStrategiesToValidatorsSupportedStrategies()` signature changed
from `IStrategy[]` to `IRewardsCoordinatorTypes.StrategyAndMultiplier[]`
— strategy and multiplier are stored atomically in one call, eliminating
the risk of a strategy being registered without a multiplier
- New `setStrategiesAndMultipliers(StrategyAndMultiplier[])` — updates
multiplier weights for existing strategies without touching the
EigenLayer strategy set
- New `getStrategiesAndMultipliers()` — returns all strategies with
their current multipliers
- `removeStrategiesFromValidatorsSupportedStrategies()` now cleans up
multiplier entries on removal
**New error / event:**
- `EmptyValidatorSet()` — reverts when no eligible candidates exist
- `StrategiesAndMultipliersSet(StrategyAndMultiplier[])` — emitted on
add or update of multipliers
## Tests (`ValidatorSetSelection.t.sol`)
New 552-line Foundry test suite covering all cases from the spec:
| Case |
|------|
| `addStrategies` stores multiplier atomically |
| `removeStrategies` deletes multiplier |
| `setStrategiesAndMultipliers` updates without touching the strategy
set |
| `getStrategiesAndMultipliers` returns correct pairs |
| Weighted stake computed correctly across multiple strategies |
| Operators with zero weighted stake are excluded |
| Unset multiplier treated as 0 |
| Top-32 selection when candidate count > 32 |
| All candidates included when count < 32 |
| Tie-breaking by lower operator address |
| `EmptyValidatorSet` revert when no eligible operators |
## Deploy Scripts
- **`DeployBase.s.sol`**: Sets a default multiplier of `1` for all
configured validator strategies after AVS registration via
`setStrategiesAndMultipliers`
- **New `AllocateOperatorStake.s.sol`**: Forge script that allocates
full magnitude (`1e18`) to the validator operator set for a given
operator. Must be run at least one block after `SignUpValidator` to
respect EigenLayer's allocation configuration delay.
## E2E Framework
- **`validators.ts` — `registerOperator()`**: Extended to deposit tokens
into each deployed strategy and allocate full magnitude to the DataHaven
operator set after registration. Previously operators registered without
staking, producing zero weighted stake and getting filtered out by the
new selection logic.
- **`setup-validators.ts`**: Added a stake allocation pass after the
registration loop, invoking `AllocateOperatorStake.s.sol` per validator.
- **`validator-set-update.test.ts`**: Added debug logging for
transaction receipts and the `OutboundMessageAccepted` /
`ExternalValidatorsSet` events.
- **`generated.ts`**: Regenerated contract bindings to include new
functions, events, and the `EmptyValidatorSet` error.
## ⚠️ Breaking Changes ⚠️
- `addStrategiesToValidatorsSupportedStrategies(IStrategy[])` →
`addStrategiesToValidatorsSupportedStrategies(StrategyAndMultiplier[])`:
callers must supply multipliers alongside strategies.
- Operators with zero weighted stake are no longer included in the
bridged validator set.
## Rollout Notes
1. PR #433 (era-targeting + submitter role) must be deployed first
2. Deploy this `ServiceManager` upgrade
3. Confirm `strategiesAndMultipliers` is set for all active strategies
(default multiplier `1` applied automatically by `DeployBase`)
4. Deploy the runtime cap-enforcement changes (spec section 10.2)
5. Submitter daemon requires no changes — continues submitting
`targetEra = ActiveEra + 1`
## Era-targeted validator set submission with dedicated submitter role
> **Note:** This PR includes a detailed specification at
[`specs/validator-set-submission/validator-set-submission.md`](https://github.com/datahaven-xyz/datahaven/blob/feat/validator-set-submitter/specs/validator-set-submission/validator-set-submission.md)
that covers the design rationale, submission lifecycle, era-targeting
rules, and failure modes. Reading the spec first will make the contract,
pallet, and daemon changes easier to follow.
### Summary
- Introduce a dedicated `validatorSetSubmitter` role on
`DataHavenServiceManager`, separating validator set submission authority
from the contract owner
- Replace the unscoped `sendNewValidatorSet` with
`sendNewValidatorSetForEra`, which encodes a `targetEra` into the
Snowbridge message payload
- Add server-side era validation in the `external-validators` pallet to
reject stale, duplicate, or out-of-range submissions
- Add a long-running TypeScript daemon that watches session changes and
automatically submits each era's validator set at the right time
### Contract changes (`contracts/`)
- **New `validatorSetSubmitter` storage slot** — set during `initialize`
and rotatable via `setValidatorSetSubmitter` (owner-only). The storage
gap is decremented accordingly.
- **`sendNewValidatorSet` → `sendNewValidatorSetForEra`** — accepts a
`uint64 targetEra` parameter and is restricted to
`onlyValidatorSetSubmitter` instead of `onlyOwner`.
- **`buildNewValidatorSetMessageForEra`** — the
`NewValidatorSetPayload.externalIndex` is now caller-supplied instead of
hardcoded to `0`.
- **New events** — `ValidatorSetSubmitterUpdated`,
`ValidatorSetMessageSubmitted`.
- **New error** — `OnlyValidatorSetSubmitter`.
- **New test suite** — `ValidatorSetSubmitter.t.sol` covering submitter
set/rotate, access control, era encoding, and legacy function removal.
### Pallet changes (`operator/`)
- **`validate_target_era`** in `external-validators` — enforces
`activeEra < targetEra <= activeEra + 1` and `targetEra > ExternalIndex`
(dedup guard).
- **New errors** — `TargetEraTooOld`, `TargetEraTooNew`,
`DuplicateOrStaleTargetEra`.
- **Tests** — five new test cases for era boundary conditions (next-era
acceptance, old-era rejection, too-new rejection, duplicate rejection,
genesis behavior). Existing `era_hooks_with_external_index` test updated
to use valid target eras.
- **Runtime test fixes** — `external_index: 0` → `1` in
mainnet/stagenet/testnet EigenLayer message processor tests to satisfy
the new validation.
### Validator set submitter daemon
(`test/tools/validator-set-submitter/`)
- Event-driven service that subscribes to finalized
`Session.CurrentIndex` via Polkadot-API `watchValue`.
- Submits once per era during the last session, targeting `ActiveEra +
1`.
- Tracks submitted eras to avoid duplicates; skips if `ExternalIndex`
already covers the target.
- Startup self-checks: Ethereum connectivity, DataHaven connectivity,
on-chain submitter authorization.
- Supports `--dry-run` mode and YAML configuration.
- Graceful shutdown on `SIGINT`/`SIGTERM`.
### Test & tooling updates
- **E2E test** (`validator-set-update.test.ts`) — calls
`sendNewValidatorSetForEra` with a computed `targetEra` and filters the
substrate event by `external_index`.
- **`update-validator-set.ts` script** — accepts `--target-era` flag;
defaults to era 1 for fresh networks.
- **CLI launch** — wires validator set update as an interactive step
after relayer launch.
- **`package.json`** — new `submitter` and `submitter:dry-run` scripts.
- Regenerated contract bindings, PAPI metadata, state-diff, and storage
layout snapshots.
### Test plan
- [x] `forge test` — passes, including new `ValidatorSetSubmitter.t.sol`
- [x] `cargo test` — passes, including new era-validation tests in
`external-validators`
- [x] `bun test:e2e` — validator-set-update suite passes with
era-targeted flow
- [x] Manual: run submitter daemon against local network (`bun
submitter`), verify it submits once per era at the correct session
## ⚠️ Breaking Changes ⚠️
- **`sendNewValidatorSet` removed** — replaced by
`sendNewValidatorSetForEra(uint64 targetEra, ...)`. Callers must now
supply a `targetEra` parameter.
- **Access control changed** — validator set submission is now
restricted to the `validatorSetSubmitter` role instead of the contract
`owner`. The submitter address is set during `initialize` and rotatable
via `setValidatorSetSubmitter` (owner-only).
- **`external-validators` pallet now validates `targetEra`** — messages
with a stale, duplicate, or out-of-range `external_index` are rejected
on-chain. Existing integrations sending `external_index: 0` will fail
validation.

## Summary
### Configuration
- Remove deprecated `deny_warnings` config key from foundry.toml
- Add global `[lint]` config to suppress naming convention warnings for
AVS/EL/ERC patterns (`mixed-case-function`, `mixed-case-variable`)
### DataHavenServiceManager Refactoring
- Rename immutable variables to SCREAMING_SNAKE_CASE
(`_allocationManager` → `_ALLOCATION_MANAGER`, `_rewardsCoordinator` →
`_REWARDS_COORDINATOR`)
- Wrap modifier logic in internal functions (`_checkRewardsInitiator`,
`_checkValidator`, `_checkAllocationManager`) to reduce contract size
- Add `_toAddress` helper with assembly for safe bytes-to-address
conversion
### Safe Typecasting
- Replace direct typecasts with OpenZeppelin's SafeCast library in
deploy scripts and test utilities
- Use `.toUint32()`, `.toUint64()`, `.toUint160()` for
overflow-protected conversions
- Replace `bytes32("wrong origin")` string cast with hex literal in test
deployer
### Code Cleanup
- Remove 25+ unused imports across script and test files
- Convert plain imports to named imports for better clarity
- Use `SafeERC20.safeTransfer()` for token transfers in tests
- Change `view` to `pure` where appropriate
## Test plan
- [x] `forge build` completes with no warnings
- [x] `forge test` passes all 10 tests
## Summary
- Add zero address validation across all functions that accept address
parameters to prevent misconfiguration
- Fix race condition in `buildNewValidatorSetMessage()` that could cause
reverts during validator deregistration
- Refactor contract for improved readability and reduced code
duplication
- Update AVS metadata URL to point to the correct hosted JSON file
## Changes
### Security & Validation
- Add `ZeroAddress` error and validate all address inputs in
`initialize`, `setRewardsInitiator`, `setSnowbridgeGateway`,
`addValidatorToAllowlist`, `registerOperator`, and
`updateSolochainAddressForValidator`
- Fix race condition: filter out zero solochain addresses in
`buildNewValidatorSetMessage()` to prevent reverts when a validator is
mid-deregistration
### Refactoring
- Replace verbose `if/revert` patterns with `require` statements for
consistency
- Inline single-use internal functions (`_createDataHavenOperatorSets`,
`_setRewardsInitiator`)
- Consolidate duplicate error types into single `ZeroAddress` error
- Rename `initialise` → `initialize` to maintain consistency with the
transparent upgradability pattern
- Optimize validator set message encoding by removing redundant wrapper
function
### Observability
- Add `SolochainAddressUpdated` event for tracking validator address
changes
### Cleanup
- Remove unused remappings from `foundry.toml`
- Fix typo in metadata description

## Summary
This PR remove the middlewares contracts from eigen layer. Instead we
are planning to use the eigne layer contract directly. It also removes
the tests related to the middleware slasher code and the mock contract
used in it.
## Motivation
When slashing an operator in the Dathaven we are going through the
substrate slashing pallet already implemented. It already allow to
configure a slashing window and/or to cancel a slashing. In the future
it will also be compatible with a government pallet. This part of code
is therefore redundant. For the same reason we remove the tests because
we are not using the slashing middleware contracts.
## What changed
* Remove the slasher middleware files
* Remove the tests related to the middleware slasher file
## Summary
- sync `contracts/lib/eigenlayer-contracts` to tag
`v1.8.0-testnet-final` and refresh `EIGENLAYER.md` with the new commit
reference
- update local/test deployment flows to deploy the upstream
`EigenStrategy`, feed it into `AllocationManager`/`StrategyManager`, and
adopt the revised `EigenPod` constructor
- drop the obsolete `AllocationManagerMock` stub and replace its usage
with targeted `vm.mockCall` stubs that return `slashOperator` share data
- adjust slasher unit tests to match the new ABI so DataHaven stays
aligned with EigenLayer 1.8 semantics
## Testing
- forge build
- forge test
## Summary
Fixes the CI build failure in the `task-ts-build` workflow caused by
Foundry v1.4.2's Solar linter not being able to resolve Snowbridge's
context-specific import remappings.
## Problem
The Snowbridge submodule uses context-specific remappings (prefixed with
`:`) for its dependencies:
- `lib/snowbridge/contracts/:openzeppelin/` → OpenZeppelin contracts
- `lib/snowbridge/contracts/:prb/math/` → PRB Math library
Foundry v1.4.2's Solar linter doesn't understand these context-specific
remappings and fails with errors like:
```
error: file openzeppelin/utils/cryptography/MerkleProof.sol not found
error: file prb/math/src/UD60x18.sol not found
```
## Solution
Added global remappings that the linter can understand:
```toml
"openzeppelin/=lib/snowbridge/contracts/lib/openzeppelin-contracts/contracts/",
"prb/math/=lib/snowbridge/contracts/lib/prb-math/",
```
### Why This Works
- The linter can now resolve `openzeppelin/` and `prb/math/` imports
globally
- These global remappings take **lower precedence** than
context-specific ones during compilation
- The compiler still uses the context-specific remappings (with `:`)
when compiling Snowbridge contracts
- The linter uses the global remappings when checking all files
## Changes
### Commit 1: Add global remappings
- `contracts/foundry.toml`: Added 2 global remapping entries
### Commit 2: Apply forge fmt
- Applied automatic formatting via `forge fmt` to ensure code style
consistency
- Multi-line formatting for long import statements and function
signatures
- No functional changes - purely formatting updates
## Testing
✅ Local build succeeds with `forge build`
✅ No Snowbridge import resolution errors
✅ `forge fmt --check` passes with no formatting issues
✅ Only linting notes/warnings remain (not errors)

2. Allowlisted sign up of operators.
3. Integration with Snowbridge to send message of new validator set.
2. Basic testing of the above functionalities.
3. Tests now use less mocked contracts (especially from EigenLayer).
4. Refactor of `SignUpOperator` script, which now supports the three
