# Extrinsic coverage (/docs/guides/evm/precompiles/extrinsic-coverage) This audit covers the runtime's `SubtensorModule`, `AdminUtils`, `Balances`, `Proxy`, `Scheduler`, `Drand`, `Crowdloan`, `Timestamp`, and `Swap` pallets. Sudo and Multisig extrinsics are intentionally outside typed precompile coverage. Generic SCALE dispatch through the Frontier `Dispatch` precompile does not count as typed coverage. A covered operation must have a stable Solidity interface or an explicit proposed typed replacement. ## Coverage summary [#coverage-summary] | Pallet | Runtime extrinsics | Typed today | Proposed signed additions | Not exposed | | ----------------- | -----------------: | ----------: | ------------------------: | ----------: | | `SubtensorModule` | 82 | 68 | 0 | 14 | | `AdminUtils` | 86 | 40 | 0 | 46 | | `Balances` | 9 | 4 | 0 | 5 | | `Proxy` | 12 | 11 | 1 | 0 | | `Scheduler` | 10 | 0 | 0 | 10 | | `Drand` | 3 | 0 | 0 | 3 | | `Crowdloan` | 10 | 10 | 0 | 0 | | `Timestamp` | 1 | 0 | 0 | 1 | | `Swap` | 6 | 0 | 0 | 6 | | **Total** | **219** | **133** | **1** | **85** | `Typed today` counts semantic coverage, not only direct dispatch to the same Rust call. For example, `registerNetwork(bytes32)` covers basic subnet registration by dispatching `register_network_with_identity` with empty identity fields. `Proposed signed additions` includes extrinsics whose highest-level pallet call accepts a non-Root signed origin. If a call also accepts Root, only its signed path is exposed: the mapped EVM caller is dispatched as `Signed`, and the pallet performs its normal authorization checks. ## Signed additions [#signed-additions] Each implemented operation is listed on the page of its target precompile: | Target precompile | Missing extrinsics assigned | | ----------------------------------------------------------------- | --------------------------: | | [Subnet](/docs/guides/evm/precompiles/subnet) | 13 | | [Staking V2](/docs/guides/evm/precompiles/staking-v2) | 20 | | [Neuron](/docs/guides/evm/precompiles/neuron) | 21 | | [Alpha](/docs/guides/evm/precompiles/alpha) | 3 | | [Account balance](/docs/guides/evm/precompiles/account-balance) | 1 | | [Proxy](/docs/guides/evm/precompiles/proxy) | 4 | | [Balance transfer](/docs/guides/evm/precompiles/balance-transfer) | 2 | | [Voting power](/docs/guides/evm/precompiles/voting-power) | 2 | | [Leasing](/docs/guides/evm/precompiles/leasing) | 1 | | [Crowdloan](/docs/guides/evm/precompiles/crowdloan) | 1 | The only remaining proposed signed operation is `Proxy.proxy_announced`. It requires a stable, versioned EVM description of the proxied runtime call and must not add another SCALE-encoded `RuntimeCall` interface. ## Extrinsics not exposed as EVM calls [#extrinsics-not-exposed-as-evm-calls] | Pallet extrinsic | Reason | | -------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Root-only `SubtensorModule` extrinsics | `dissolve_network`, `root_dissolve_network`, `swap_coldkey`, `sudo_set_tx_childkey_take_rate_limit`, `sudo_set_min_childkey_take`, `sudo_set_max_childkey_take`, `set_pending_childkey_cooldown`, `reset_coldkey_swap`, `sudo_set_num_root_claims`, and `sudo_set_voting_power_ema_alpha` require Root. | | `SubtensorModule.schedule_swap_coldkey` | Deprecated compatibility call that always returns `Deprecated`. | | `SubtensorModule.faucet` | Build-feature-only development call; it is not part of the production runtime interface. | | `SubtensorModule.set_tempo` | Retained call-index compatibility entry point that succeeds without changing state. The real setting is exposed as `SubnetPrecompile.setTempo` through `AdminUtils.sudo_set_tempo`. | | `SubtensorModule.set_activity_cutoff_factor` | Retained call-index compatibility entry point that succeeds without changing state. The active AdminUtils operation is already covered by `SubnetPrecompile.setActivityCutoffFactor`. | | Root-only `AdminUtils` extrinsics | Root-only administration is not delegated to EVM callers. For calls that also accept a signed subnet owner, the domain precompile dispatches the highest-level call as the mapped EVM signer and preserves its authorization checks. | | `AdminUtils.sudo_set_total_issuance` | Deprecated call that always returns `Deprecated`. | | `Balances.burn` | The native call reduces FRAME Balances issuance without updating Subtensor's separate issuance ledger, which drives block emission. It is not exposed until the runtime provides a synchronized signed burn operation. | | Root-only `Balances` extrinsics | `force_unreserve`, `force_transfer`, `force_set_balance`, and `force_adjust_total_issuance` require Root. | | All `Scheduler` extrinsics | `Scheduler.ScheduleOrigin` is configured as Root in the runtime. | | `Drand.write_pulse` | Unsigned offchain-worker submission requiring `None` origin. An EVM caller cannot satisfy that origin without changing its security model. | | Drand configuration extrinsics | `set_beacon_config` and `set_oldest_stored_round` require Root. | | `Timestamp.set` | Block-production inherent requiring `None` origin. Contracts already receive the same time through `block.timestamp`. | | `Swap.set_fee_rate` | Requires Root. | | `Swap.add_liquidity` | Permanently disabled pallet call that always returns `Deprecated`. | | `Swap.remove_liquidity` | Permanently disabled pallet call that always returns `Deprecated`. | | `Swap.modify_position` | Permanently disabled pallet call that always returns `Deprecated`. | | `Swap.toggle_user_liquidity` | Permanently disabled pallet call that always returns `Deprecated`. | | `Swap.disable_lp` | Permanently disabled pallet call that always returns `Deprecated`. | These exclusions preserve the existing runtime origin and lifecycle semantics. A typed precompile must not manufacture Root or `None`, call an internal helper, or write storage directly to make one of these operations callable.
