Place Trait Bids

Learn how to create attribute bids for collections.

Reservoir allows you to create attribute or trait bids for collections. With this guide, we'll go over the best way to implement attribute offers using the SDK, ReservoirKit, and APIs. You'll also learn how to send these bids to specific order books or platforms.

Reservoir SDK

Using placeBid in the SDK, you can create attribute or trait bids. You'll need to use the available params from the Create Bids API to pass in the SDK. This will allow you to create attribute offers. Remember to set orderbook and corresponding orderKind to the platform you want to submit the order; you can find the most current list in our Bid API.

In the code example below, you will see that the attributeKey and attributeValue are both passed. These are both case sensitive. You will also need to include the collection id.

import { getClient, Execute } from "@reservoir0x/reservoir-sdk";
import { createWalletClient, http } from 'viem'


address = "0x8ba1f109551bD432803012645Ac136ddd6000000"
wallet = createWalletClient({
  account: address,
  transport: http()

  bids: [{  
      weiPrice: 10000000000000000,  
      orderbook: 'reservoir',  
      orderKind: 'seaport-v1.5',  
      collection: "0xbd3531da5cf5857e7cfaa92426877b022e612cf8",
    	attributeKey: "Face",
      attributeValue: "Normal",
   		expirationTime: "1775066025"
  onProgress: (steps: Execute['steps']) => {


The BidModal will be used to create attribute bids or trait offers. You'll need to pass the attribute param in the payload to create the offer. Currently, all orders created with ReservoirKit will be submitted to the Reservoir native orderbook. You can see full distribution of these offers in our Supported Marketplaces doc. If you need to be able to publish offers to other orderbooks besides Reservoir, we recommend using the SDK.

Check out the code sample below for making a trait offer in Reservoir's orderbook:

import { BidModal } from '@reservoir0x/reservoir-kit-ui'
import { useState } from 'react'

      Place Bid
   key: "Face",
   value: "Normal"
  onBidComplete={(data) => {
    console.log('Bid Complete', data)
  onBidError={(error, data) => {
    console.log('Bid Transaction Error', error, data)
  onClose={(data, stepData, currentStep) => {
    console.log('BidModal Closed')

Reservoir API


We recommend using Reservoir SDK

Reservoir SDK includes helpers that abstract the process of iterating through steps, and returning callbacks that can be used to update your UI.

To place trait or attribute bids, you'll need to pass a collection id, attributeType, and attribute in the payload. You can also set the orderbook and orderKind; below we set them to reservoir and seaport-v1.5. You can see currently available orderbooks and order kinds in the Bid API doc.

Below is a code example:

curl --request POST \
     --url \
     --header 'accept: */*' \
     --header 'content-type: application/json' \
     --header 'x-api-key: 440c94e2-0f99-5c9e-8251-fee751d21aa1' \
     --data '
  "params": [
      "orderKind": "seaport-v1.5",
