getApp gets the appropriate app based on the latest application version.

BeginBlocker processes automatic state transitions at the beginning of each block

ChainID returns the chain ID of the state machine.

DeriveForwardingAddress derives the forwarding address for given parameters.

Exists checks whether the Tx exists in the cache and the blobs match the cached blobs

NewBlob creates a new [Blob] instance by encoding the data. It takes ownership of data and may reuse it directly as backing storage for original rows.

Params queries the parameters of the module.

SetWithdrawal saves a withdrawal to both indexes: 1. Primary index: withdrawals_by_signer/{signer}/{requested_timestamp} 2. Secondary index: withdrawa

Slabs returns the total count of live slabs (in-use plus free) across all buckets. For tests and observability; locks each bucket briefly.

Config returns the blob's configuration.

DefaultServerConfig returns a [ServerConfig] with default values.

DepositToEscrow deposits funds to the signer's escrow account

Store returns the server's store.

makePaymentPromise creates a test [fibre.PaymentPromise] with the given private key.

Helper functions

Close cleans up test resources

ComputeRootFromProof computes the Merkle root given a leaf and its proof
