Builds a healthy test [`ProverInstance`] with no launch time.

Initialize tracing for tests with sensible defaults. Uses `tracing_subscriber::fmt().with_test_writer()` for test output capture. Only initializes on

Insert a header into the mock chain provider.

Returns true if ecotone is active for the payload.

Returns true if holocene is active for the payload.

Enable Jovian at genesis.

Returns an L2 client provider with Base network.

Return the most recently mined block.

Notify the sync target that a revert has been processed up to the given block. Only strips the revert portion if the pending revert target is at or a

Creates a mock L2 provider with multiple blocks and returns a vec of expected output roots (one per block).

Determines what the next L1 origin block should be, based off of the [`L2BlockInfo`] unsafe head. The L1 origin is selected based off of the sequenci

Walks down the trie to a leaf value with the given key, if it exists. Preimages for blinded nodes along the path are fetched using the `fetcher` funct

Returns the first transaction submission endpoint.

Submit a prove-block-range proof request. Because `session_id` is required by the protocol, retries are safe to issue without enqueueing duplicate pr

Removes metering data for the given transaction hashes. Used to eagerly evict entries for transactions that have been included in a flashblock so the

Returns a previously reserved nonce for reuse. Called when a `send_async` task fails before publishing, making the pre-reserved nonce available for r

Return a JSON-RPC client connected to the harness node.

Returns the inner chain spec with runtime hardfork overrides materialized.

Returns the seeded `(address, [slot; SLOTS])` pairs in the order they were inserted.

Send a [`NetworkPayloadEnvelope`] into the transport channel.

Returns an RPC error indicating the sequencer is not available on this node.

Sets a bit in the [`SpanBatchBits`] bitlist.

Sets the earliest retained block number/hash under the history write lock.

Builds an MDBX-backed storage seeded with several accounts and storage slots so cursor walks have non-trivial work to do. Returns the temp dir (must

Create a request in RUNNING state with an associated proof session. Returns `(request_id, backend_session_id)`.

A [`ConfigChange`] whose `auth` is a fresh signature over its own digest.

Performs an SLOAD (persistent storage read).

Future that resolves when the server stops.

Builds a test driver with an optional TEE config.

Returns the activation timestamp, if the upgrade is timestamp-activated.

Converts this test config into a `LoadConfig` for runtime use.

Track a transaction being included in a block or dropped.

Moves `amount` tokens from `from` to `to` using `spender`'s allowance. Emits `Transfer`. Skips allowance decrement when allowance is `U256::MAX`. The

Truncates a value to fit in a fixed terminal column.

Attempts to enqueue an engine query without waiting for channel capacity. Public RPC requests fail fast under load so they cannot block consensus-cri

Unwind the historical state to `unwind_upto_block` (inclusive), deleting all history starting from provided block. Also updates the `ProofWindow::Late

Uploads snapshot artifacts with diff-based optimization. Static file chunks go to `{prefix}/static_files/` and are skipped when their per-file BLAKE3

Returns a function that extracts the relevant resource usage from a transaction.

Validates one claimed output root at a specific L2 block. Fetches the L2 header and `L2ToL1MessagePasser` storage proof at the provided L2 block numb

Sets the chain ID.

Overrides the channel timeout used before and after Granite activation.

Sets the account nonce.

Attach an external L2 safe head watch channel. When the receiver fires, the pipeline's [`prune_safe`](BatchPipeline::prune_safe) is called with the n

Sets the private key used to sign the transaction.

Get the Ethereum address from a signer.

Returns all known chain configurations, including devnet.

Defaults the execution upgrade-signal L1 RPC from another service's L1 RPC when unset.

Applies the time-independent Boundless offer overrides to request params. `min_price`, `max_price`, `ramp_up_period`, and `lock_timeout` are only pas

Returns the label used for logs and metrics.

Build a minimal [`AttributesWithParent`] whose derived L2 block number is `l2_parent_number + 1` and whose L1 origin is `l1_origin_number`.

Returns the blob gas used for this payload.

Broadcast `block` as a [`base_common_rpc_types_engine::NetworkPayloadEnvelope`] to the wired [`SupervisedP2P`] handle.

Builds a test genesis with Base Azul, Beryl, and Cobalt all enabled at timestamp 0. Extends [`build_test_genesis_azul`] with: - Base Beryl and Cobalt

Validates and records an expiring-nonce transaction, providing replay protection for nonce-free EIP-8130 transactions. `expiring_nonce_hash` is the s

Returns the underlying worker client.
