3 | This is an NFT sniper bot that is written in pure JavaScript does NOT require any js node implementation and nothing to be installed.
4 |Once you configure the settings in the "config.js" you simply open the index.html file in any web browser all code runs locally and he's searching in buy calls are made with web3 calls.
5 |This sniper bought has now scored me two boardapeyachtclubs for well under the floor price among many other collections I enjoy.
6 |Setting up is pretty straightforward first download the zip file here
7 |A helpful tester has created a video tutorial, providing step-by-step instructions on how to run the program.
8 | 9 | https://vimeo.com/874749226 10 | 11 | 12 |You can Download the zip file of the program here
13 | 14 | https://raw.githubusercontent.com/Tech9Geek/Tech9Geek-Javascript-NFT-OpenSea-Sniper-Bot/main/Tech9Geek-Javascript-NFT-OpenSea-Sniper-Bot.zip 15 | 16 | here's the program in action finding and buying a bored ape yacht club 17 | 18 |
19 |
20 | then when you unzip to a location is easy for you to locate open the config.js file in any text editor in my case notepad
21 |
22 | 
23 |
24 |
25 | you'll need to configure the settings
26 | 1. put in your ETH public address leave the quotations in.
27 | 2. put in your ETH private key to that public address you just entered
28 | 3. if you're using a hardware wallet that does not give you easy access to your private keys you can put in your wallet seed, but make sure you still put in your public address you want it to utilize
29 | 4. set the marketplace you want to use by default it's set to 1 which is opensea ,2 = raribles ,3 = conbaseNFT
30 | 5. set the network default set for 1 which is ETH , to uses the polygon network replace that with a 2
31 | 6. set the maxspend to what you wish to spend on the NFT
32 | 7. set the nft collection ID default it's on boredapeyachtclub
33 | for the opensea collection name "https://opensea.io/collection/boredapeyachtclub" <- take this part of the url for example: "boredapeyachtclub"
34 | for the Raribles "https://rarible.com/boredapeyachtclub/items" <- take this part of the url for example: "boredapeyachtclub"
35 | for the coinbaseNFT "https://nft.coinbase.com/collection/ethereum/0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D" <- take this part of the url for example: "0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D"
36 |
37 | 
38 |
39 | save the settings you just configured
40 |
41 | now right click on index.html and select open with and choose any web browser in my case I love to use Firefox
42 |
43 | 
44 |
45 |
46 |
47 | Please take time and for me in the 2024 codeathon I won 4th place last year and would love your vote!

It is a cryptographically-secured digital token that can represent a wide variety of digital assets, such as artwork, music, videos, collectibles, and more. Crypto NFTs provide ownership rights, scarcity, and transferability to the assets they represent.
52 |
53 | Core Components: Crypto NFTs are composed of several essential components, including a unique identifier, ownership records, and smart contract code. The identifier is a string of characters that represent the NFT, and is used to distinguish it from other NFTs. Ownership records are stored on a distributed ledger and used to track the
