Set the Auction bid buffer
// the bid buffer in basis points
const bufferBps = 5_00; // 5%
setBidBufferBps(bufferBps: BigNumberish): Promise<void>;
|bufferBps||BigNumberish||the bps value|
A percentage (e.g. 5%) in basis points (5% = 500, 100% = 10000). A new bid is considered to be a winning bid only if its bid amount is at least the bid buffer (e.g. 5%) greater than the previous winning bid. This prevents buyers from making very slightly higher bids to win the auctioned items.
