## Bidding

Users can bid on auctions using the `MsgPlaceBid` message type. All auction types can be bid on using the same message type.

|
|
||
|
|
```go
|
||
|
|
// MsgPlaceBid is the message type used to place a bid on any type of auction.
|
||
|
|
type MsgPlaceBid struct {
|
||
|
|
AuctionID uint64
|
||
|
|
Bidder sdk.AccAddress
|
||
|
|
Amount sdk.Coin
|
||
|
|
}
|
||
|
|
```
|
