Settlement Duration
Time taken for a cross-chain asset transfer to settle.
Goerli → Rococo
Minimum: 15min
Average: 18min
Maximum: 30min
Rococo -> Goerli
Our rococo parachain is configured to create new message batches every block. In production, batching times will increase, so the figures below will also increase accordingly.
Minimum: 5min
Average: 5min
Maximum: 10min
Relayer transaction fees
These are the transaction fees paid by relayers for delivering messages.
Polkadot->Ethereum
The transaction fees for relaying a message bundle are highly variable, and depend on the bundle size and fluctuating gas costs.
For a bundle with a single message, the cost will range between roughly $10 to $20 in the current bear market. The cost can be broken down roughly as follows:
50% of gas is used for bundle verification
50% of gas is used for dispatch and execution of the single message
The overhead of bundle verification is nearly constant, so bundles of larger sizes will see proportionately more gas used for message execution rather than verification.
See this spreadsheet for the raw calculations.
