NFT Trait-Based Offer Maker

WHAT IT DOES

NFT Trait-Based Offer Maker enables users to create offers for NFTs based on specific traits and rarity scores. The tool reads your connected wallet address, NFT collection contract address, trait metadata (rarity scores, trait types, trait values), floor price, trait-based offer parameters, total offer budget, current block timestamp, gas prices, and marketplace fee structures. It fetches all NFTs that match the specified trait and rarity range, filters them within your budget, and displays a detailed list of matching NFTs. Once confirmed, the tool creates offers for all matching NFTs, streamlining the process of acquiring specific trait combinations.

HOW TO USE

Connect your wallet and select your network. Enter the NFT collection contract address, the trait type (e.g., background, eyes, hat), the trait value (e.g., gold, red), and optional rarity score range. Specify the offer price per NFT and your total offer budget. Click "Find matching NFTs" to load all NFTs that match your trait and rarity filters, along with their rarity scores. The tool displays a detailed table showing each matching NFT and its rarity. Review the summary including the total cost and budget. If everything is correct, click "Make trait-based offers" to create offers for all matching NFTs.

THE REAL MECHANISM — TRAIT-BASED OFFER CREATION WITH RARITY FILTERING AND BUDGET TRACKING

Unlike simple offer tools that target specific token IDs, this tool uses trait-based filtering to find NFTs with specific attributes. The getTokensByTrait function returns all token IDs that have a specific trait type and value. The getTokenTraits function returns the trait types, trait values, and rarity scores for each token. The tool filters the tokens by rarity score range, calculates the total cost by multiplying the offer price by the number of matching NFTs, and verifies that the total cost is within the user's budget. The offer creation function takes the collection address, token IDs, and offer price as parameters, creating offers for all matching tokens in a batched transaction. The tool uses ethers.js BigNumber with the token's decimal precision, and gas costs are reported using receipt.effectiveGasPrice. The tool validates that there is at least one matching NFT and that the total cost does not exceed the budget before enabling the offer button.

WHAT IT CANNOT SEE

Cannot verify trait rarity accuracy off-chain—the tool relies on the contract's rarity scores and cannot verify their accuracy. It cannot ensure offer competitiveness—the tool cannot guarantee that the offers will be accepted. It cannot predict market demand—the tool cannot forecast whether there is demand for the specified traits. It cannot detect if the collection contract contains vulnerabilities—the tool does not audit the contract logic. It cannot recover funds if offers are made and later rejected.

PLEASE NOTE — EVM CHAINS ONLY

This tool exclusively supports EVM-compatible chains where ethers.js can connect via standard JSON-RPC. It does not support non-EVM chains such as Solana, Tron, Starknet, SUI, TON, Aptos, Bitcoin, Cosmos, or XRP. The collection contract must implement the specific interface expected by this tool (getTokenTraits, getTokensByTrait). Always review the trait filters and offer parameters before making offers. This tool is an offer creation interface, not a financial advisor or investment strategist.
