## Submit Tx
```mermaid
sequenceDiagram
autonumber
Eth Client->>+Arbitrage Engine: Chain state for latest block
Arbitrage Engine->>+Arbitrage Engine: Analyze txs + receipts
Note over Arbitrage Engine,Arbitrage Engine: Looking for our bundles
loop Each bundle that we identify
loop Each tx
Arbitrage Engine->>+Arbitrage Engine: Evalute tx status
alt Tx reverted
else Tx success
Arbitrage Engine->>+Profit Distributor: Request to refund part of the [TX_RECEIPT_CREDIT] to theFee Receipent
Note over Arbitrage Engine,Profit Distributor: It may be more efficient to batch up refunds etc.
end
end
end
Profit Distributor->>+Profit Distributor: wait n confirmations
Profit Distributor->>+Eth Client: A series of txs for refunding [TX_RECEIPT_CREDIT] to Fee Receipent
Note over Profit Distributor,Eth Client: If Fee Receipent refund is ever something other than Ether, perhaps the MEV relay would be better for this
```
### Submit Tx Bundle
```mermaid
sequenceDiagram
autonumber
User->>+Web3: submit tx bundle with target block number
Web3->>+Web3: validate target number is for a block that has not been mined
alt Target block number has already been mined
Web3->>+User: Return error
end
loop Each tx in bundle
Web3->>+Web3: validate tx is for a supported market
alt Unsupported market
Web3->>+User: Return error
end
end
alt All markets supported and target block has not been mined
Web3->>+Bundler: forward user bundle
Bundler-->>-Web3: ack user bundle
Web3-->>-User: ack tx bundle
Bundler->>+Bundler: Aggregate & partition by (block number, market)
Note over Bundler,Bundler: User bundles are preserved atomically
Bundler->>+Arbitrage Engine: forward one or more bundles
Eth Client->>+Arbitrage Engine: Target block number parent is mined
Note over Eth Client,Arbitrage Engine: Latest market state is included in this update
loop For each bundle targetting the next block number
Arbitrage Engine->>+Arbitrage Engine: estimate price impact & interleave arbitrage orders
Arbitrage Engine->>+Arbitrage Engine: determine profitability
alt Profitable
Arbitrage Engine->>+Arbitrage Engine: determine miner bribe
Arbitrage Engine->>+Eth Signer: forward backbone bundle
Eth Signer->>+Eth Signer: de-reference arbitrage orders for real orders
Eth Signer->>+Eth Signer: generate miner bribe tx
Eth Signer->>+MEV Relay: forward bundle
MEV Relay->>+Miner: relay bundle
end
end
end

### Profit Distribution

```
### Handling Fork
```mermaid
sequenceDiagram
autonumber
Eth Client->>+Arbitrage Engine: The block number of the earliest common ancestor
Arbitrage Engine->>+Arbitrage Engine: Arbitrage Engine enters fork mode
Arbitrage Engine->>+Arbitrage Engine: Reverse out any state back to the earliest common ancestor
Note over Arbitrage Engine, Arbitrage Engine: Things such as User positions, refunds, stats and so on
Eth Client->>+Arbitrage Engine: Fork blocks in order with txs and receipts etc.
loop each fork block
Arbitrage Engine->>+Arbitrage Engine: Analyze txs + receipts
Note over Arbitrage Engine,Arbitrage Engine: Looking for our bundles
loop Each bundle that we identify
loop Each tx
Arbitrage Engine->>+Arbitrage Engine: Evalute tx status
alt Tx reverted

end
end
end
end
Eth Client->>+Arbitrage Engine: A full snapshot of market data for the new head
Arbitrage Engine->>+Arbitrage Engine: Arbitrage Engine leaves fork mode
Profit Distributor->>+Profit Distributor: wait n confirmations
Profit Distributor->>+Eth Client: A series of txs for refunding [TX_RECEIPT_CREDIT] to Fee Receipent
Note over Profit Distributor,Eth Client: If User refund is ever something other than Ether, perhaps the MEV relay would be better for this
