Release Notes

Upgrade Priority: Medium (timely upgrade recommended)

Highlights:

• Implement foreign asset transaction fees
• Add prediction market and swaps proxies
• Integrate --relay-chain-rpc-url flag

Implementation of foreign asset transactions
This release introduces the ability to pay transaction fees using foreign assets, such as DOT. This will empower users to interact with certain components of the protocol, such as liquidity provision and trading, even if they only hold foreign tokens. For users who hold multiple tokens, it is now possible to select one dedicated token to be used specifically for fee payment (note: token selection happens off-chain).

Add prediction market and swaps proxies
Accounts are now capable of delegating certain interaction privileges within the core prediction markets protocol to other accounts by utilizing proxies. For instance: One account can allow another account to create markets, report outcomes, dispute outcomes, trade, manage existing liquidity and add new liquidity on their behalf. Any combination of these privileges is possible.

Integrate --relay-chain-rpc-url flag
From this release onward, node operators can utilize the relaychain flag --relay-chain-rpc-url to specify an URL to a relaychain node that is used during block production. By default, every Zeitgeist node internally spawns a relaychain node to synchronize with the relaychain. Using --relay-chain-rpc-url, considerable hardware costs can be saved, especially for node providers of multiple parachain nodes.

The swaps pallet now exposes an RPC that returns all asset prices of a specific swap pool in one single request.
Most of the remaining changes in this release deal with the automation of several aspects of the collaborative work on GitHub.
