NFT Trait Swap Executor

WHAT IT DOES

NFT Trait Swap Executor is a specialized NFTs application that swaps traits between NFTs using rarity scores, compatibility checks, and swap history tracking for trait customization. It reads the NFT contract state and trait swap contract state to verify user NFT holdings and trait availability. The tool fetches token IDs lists, trait IDs lists, swap eligibility, swap fee amount, and payment token state. It reads the user's balance, allowance, swap history, trait rarity scores, trait compatibility, swap result NFT metadata, and swap count. The tool also reads gas price, block timestamp, chain ID, NFT ownership proof, and trait availability status. It supports four key actions: swapping traits between NFTs, batch swapping multiple trait pairs, reverting a previous swap, and verifying swap validity.

HOW TO USE

Connect your wallet and select your network from the dropdown. Paste the NFT contract address, trait swap contract address, and optionally a payment token address. Enter the source NFT token ID, target NFT token ID, and the trait IDs to swap (comma-separated). Click "Check Traits & Status" to verify your NFT ownership, trait rarity scores, swap eligibility, and compatibility. The tool displays NFT holdings, trait rarity scores, swap eligibility, swap fee, trait compatibility, swap history, swap count, and trait availability. To swap traits, click "Swap Traits"—the tool validates eligibility and processes the swap. To swap multiple trait pairs simultaneously, click "Batch Swap". To revert a previous swap, click "Revert Swap". The action preview shows the source-to-target pair, trait IDs, swap fee, and eligibility status before submission.

TRAIT SWAP AND RARITY VERIFICATION ENGINE

The tool implements a comprehensive trait swapping engine that validates rarity scores and compatibility before executing swaps. It reads the user's NFT holdings using balanceOf and verifies specific token ownership with ownerOf for both source and target token IDs. The tool checks swapEligible to confirm the user owns both NFTs and that the requested trait swap is permitted by the contract. It reads traitRarityScores for each NFT to display the rarity values of individual traits, helping users understand the value implications of swaps. The tool also reads traitCompatibility to verify that the source and target traits are compatible—some contracts restrict swaps between certain trait types. The tool reads swapFee to display the cost, which may vary based on the number and rarity of traits being swapped. When processing a swap, the tool constructs a swapTraits transaction with the source ID, target ID, and trait ID array—the contract verifies ownership, compatibility, collects payment, transfers the specified traits between NFTs, and updates the metadata. The tool reads swapHistory to display past swap operations and swapCount to track the total number of swaps performed. For batch operations, the tool calls batchSwap with an array of swap structures, processing multiple swaps in a single transaction. The tool also reads traitAvailability to confirm that the requested traits are available for swapping. For reverts, the tool calls revertSwap with the swap ID, which restores the original trait configuration. The tool also supports verifySwap to confirm that a swap was executed correctly. Gas estimation uses the provider's fee data with a safety multiplier, and the tool validates that the user has sufficient balance for both the swap fee and gas costs.

WHAT IT CANNOT SEE

This tool cannot verify that the swapped trait combination is visually desirable, aesthetically pleasing, or valuable. It cannot detect if the trait swap contract has bugs, has been exploited, or contains malicious logic. It cannot guarantee that the swap transaction will succeed if the payment fails or if the contract state changes. It cannot recover original traits if the swap fails or reverts. It cannot verify that the trait rarity scores are accurate off-chain or that the rarity data is reliable. It cannot provide financial, investment, or trading advice. It cannot ensure that the swapped NFT will retain value or be marketable. It cannot detect if the trait swap contract has been upgraded or modified. It cannot predict future swap costs or trait availability. It cannot verify off-chain trait rarity guarantees, value assessments, or aesthetic judgments.

PLEASE NOTE

This tool supports EVM-compatible chains only. It requires an active RPC connection and a wallet with signing capabilities. The tool does not custodial funds or private keys. Always verify NFT ownership and trait details before swapping. Trait swaps are irreversible unless revert is supported by the contract. Batch swaps may consume more gas but save on multiple transactions. The tool is for informational and experimental use; you bear full responsibility for trait swap decisions.
