Derives the signer address for a private key.

Take the current pending state, leaving `None` in its place. Used by the sync loop to consume the next action to perform.

Update the sync target state and wake the sync loop. If there is already a pending state, the new state is merged using [`SyncTargetState::apply_next

Appends more data to [`Hint::data`].

Returns a slice of all accounts.

Applies the update to the provided sync state, using the current state values if the update is not specified. Returns the new sync state.

Display label for pretty output.

Returns the label as a static string.

`authenticator(20) || data`.

Returns the L2 block number for the payload attributes if made canonical. Derived as the parent block height plus one.

Builds a [`BaseEvm`] with a `()` inspector. The inspect flag is `false`, so [`Inspector`][revm::Inspector] callbacks are never invoked via [`alloy_evm

Builds a test genesis with Base Azul (Osaka) enabled at timestamp 0. Extends [`build_test_genesis`] with: - `osaka_time` set to 0 - Base Azul activat

Computes this variant's deterministic token address for `creator` and `salt`. Returns the address and the 9-byte hash tail embedded in the address.

Creates a signed transaction with the given parameters.

Discovers claimable games via two-tier scanning. Incremental** (every call): scans from `bond_scan_head` to `game_count`, catching newly created game

Set the enveloped transaction bytes.

Returns `true` if transaction is deposit transaction.

Returns if holocene is active.

Asserts that the frame queue produces the expected frames.

Returns the number of encoded-but-not-yet-staged pending frame submissions.

Update the initial state with the provided diff. Prune all historical trie data till `new_earliest_block_number` (inclusive) using the [`BlockChangeSe

Publishes a simple value-transfer tx and returns the hash, send state, and raw transaction bytes.

Records that a transaction was successfully published.

Sets up a test instance with custom `BuilderConfig`. The flashblocks WebSocket port will be automatically set to an available port if set to 0.

Bind and start the admin server on the given socket address.

Moves `amount` tokens from `from` to `to`. Emits `Transfer`. When `privileged` is true (factory bootstrap window) only the policy checks are skipped;

Sets the chain ID of the network.

Set the origin block.

Sets the safe head

Returns the payload attributes.

Builds a new block using the current state of the chain and the transactions in the pool.

Build `count` sequential L2 blocks with one user transaction each.

Fire receipts for all staged items from `block` and yield to let the driver process confirmations and the L1 head event.

Creates a B-20 token through the factory and returns the deterministic token address.

Helper to create an empty [`MockDisputeGameFactory`] behind an `Arc`.

Builds an EVM with `balance` funded to `sender`, optionally deploying `code` at the given contract addresses.

Generates a random value in the given range.

Initialize the tracing subscriber with the configured options. This sets the global default subscriber. Should only be called once. Includes default

Serializes `signed` (EIP-2718) and computes intrinsic gas, mirroring a caller that already holds the transaction's network encoding.

Returns `true` if the buffer contains no entries.

Returns true if isthmus is active for the payload.

Returns true if the transaction would exceed the block limits: - block gas limit: ensures the transaction still fits into the block. - tx DA limit: if

Helper to build mock game state with an explicit TEE prover address.

Returns the cache name.

Creates the next flashblock context with updated gas and DA targets. Increments the flashblock index and sets new target limits for the next flashblo

Adds `n` newly-compressed bytes, emitting a progress log once per interval.

Reserves the next nonce and immediately releases the lock, returning the raw `u64` value. Unlike [`next_nonce`](Self::next_nonce), this method does *

Submit the first `n` pending frame txs/blobs to the L1 miner's queue without mining. Returns the actual count staged.

Submit L2 blocks through the batcher, then publish the mined L1 block. Returns the [`BlockInfo`] for the L1 block that carried the batcher submission

Registers a game for bond tracking if its `bond_recipient` is in the configured claim addresses. Returns `true` if the game was added to tracking.

Adds or removes `accounts` from the allowlist for an ALLOWLIST policy.

Updates the state for a specific game address. Multi-step driver tests call this between steps to simulate on-chain state changes (e.g. marking a gam

Make the block v1 compatible

Value-transfer candidate with the given amount.

With expected frames.

Adds frames to the mock provider.

Sets the L2 chain ID.

Returns the game addresses with pending proofs.

Parse a mock CLI command with required args plus any overrides. The base defaults do **not** include signer flags (`--private-key` / `--signer-endpoi

Creates a token at a deterministic address derived from `(caller, variant, salt)`.

Returns a reference to the underlying [`BaseContext`].
