problem description
EVM need support limit order via precompile.
limit orders, like limitBuy, limitStopLoss, limitTakeProfit are supported in the limit-order pallet in #2554.
The flow is:
Users sign the off-chain orders (any of the above)
Relayers has a validation engine that checks if a specific order will pass, and submit those orders on-chain.
The pallet validates orders (signature verification + order condition) and execute them either in sequence - execute_orders or in batch: execute_batched_orders.
Describe the solution you'd like
The possible solution will be provided later. Current blockers as follows:
- rate limiting on (hotkey, coldkey, netuid), so there is no way to do several operations from the batch.
- intermediary address - for now how pallet is doing it, it can balance sells and buys to redistribute funds across across orders in batch.
- off-chain signatures - we need to validate user's signature and be able to do the staking operation on user's behalf, we have transferStakeFrom that enforce to submit on-chain transaction before the actual order.
- use MEV shield on top of it.
