EventExecuteOrdersForPair​

This event triggers when some orders for a pair execute at a block. The pool_id, token_in, token_out, and whitelisted_route identify the pair.

Buy orders purchase the token_out. Each buy order has an EventExecuteOrder object with the order's id, its matched amount, and the amount traded against the amm pools.

The event also includes the buy and sell prices at execution time, the total amount traded against the pools for each side, and the matched amounts. The output of matching for sell orders equals the matched amount for the buy orders and vice versa. But this does not apply to trades. The actual output amounts of trades against the pools are in separate fields in the event.

  ];
  ExitType exit_type = 7;
}

EventJoinPool​

EventJoinPool is an event triggered when liquidity is deposited into a pool. The TokenAmount objects display the token balance post-operation, and the amount property represents the token amount in circulation for this operation.

message EventJoinPool {
   uint64 pool_id = 1;
   JoinSummary summary = 2 [(gogoproto.nullable) = false];
}

message JoinSummary {

  ];
  SwapType swap_type = 8;
}

EventYAssetSwap​

The EventYAssetSwap is emitted upon a yASSET swap. These swaps entail an underlying swap against the pool and a refract/redeem action. The EventSwap is also emitted for the underlying swap, with additional yASSET trade details found in this event. Note that the fee here differs from the swap fee or the swap-protocol fee, which are charged for all operations; this is detailed in the yASSET trade section.
