Remove Dynamic Transaction

[salman01zp]

Overview

Since subxt introduced encoding SubmittableExtrinsic we can directly enqueue signed SubmittableExtrinsic bytes in tx-queue and then later execute it.

Enqueue Transaction

let acknowledge_proposal_tx = tx_api.acknowledge_proposal(
            nonce.clone(),
            src_chain_id,
            ResourceId(resource_id.into_bytes()),
            BoundedVec(proposal.to_vec()),
        );

 let signer = &self.pair;
 let signed_acknowledge_proposal_tx = self
       .client
       .tx()
       .create_signed(&acknowledge_proposal_tx, signer, Default::default())
       .await?;

// Enqueue transaction in substrate transaction queue
        QueueStore::<Vec<u8>>::enqueue_item(
            &self.store,
            tx_key,
            signed_acknowledge_proposal_tx.into_encoded(),
        )?;

Dequeue and execute Transaction

// dequeue signed transaction
 let maybe_call_data = store.dequeue_item(
    SledQueueKey::from_substrate_chain_id(chain_id),
)?;
if let Some(payload) = maybe_call_data {
    let signed_extrinsic = SubmittableExtrinsic::from_bytes(
        client.clone(),
        payload,
    );

    // dry run test
    let dry_run_outcome = signed_extrinsic.dry_run(None).await;

    // watch_extrinsic submits and returns transaction subscription
    let mut progress = signed_extrinsic
    .submit_and_watch()
    .map_err(Into::into)
    .map_err(backoff::Error::transient)
   .await?;

Checklist

• Update Substrate Bridge Handler
• Remove Dynamic transactions

This actually could also solve #474.
