Mint explorers recorded NFT transfers on its now retired Ethereum Layer 2 network

Mint used a block explorer and an NFT-specific explorer to organize NFT transfers by collection contract and token ID. General operations ended on April 17, 2026. Surviving indexed records remain useful for interpreting historical activity when the relevant data is accessible. They do not establish that the retired network still supports NFT trading or withdrawals.

A transfer record connects a collection contract and token ID with the transaction that reported the transfer. Those relationships explain what an archive can establish about a holding, even when a marketplace or image service has stopped working.

Collection records after shutdown

Collection pages that retained Mint data could expose past transfers, holder totals and NFT inventory after general operations ended. A transfer entry described a historical event; an inventory view represented the dataset's indexed state. The availability of those records depended on the explorer service and its database, separately from the network's ability to accept new transactions.

The block explorer and NFTScan

Mint Explorer covered blocks and transactions, while Mint NFTScan provided NFT-focused search and indexing. The latter launched on May 20, 2024, alongside NFT API support for the network. These components connected execution records with information organized around NFT assets. The API provided software with access to indexed data, while the NFT explorer presented records for direct browsing.

Block pages supplied timestamps, block numbers and transaction lists. NFT collection pages exposed transfer rows with transaction hashes, sending addresses, receiving addresses and item IDs. Holder and inventory tabs represented other views of the collection. A transaction list described executions, while an inventory concerned tokens. Those views served different purposes, so a transaction total could not substitute for a collection's token count.

Network and record identifiers

Chain ID 185 identified Mint mainnet, which was distinct from Ethereum mainnet despite its Ethereum-compatible execution environment. Each collection contract's code and token state belonged to its deployment on that network. The contract supplied the context for its token IDs. Within an ERC-721 collection, the contract address and token ID identified the particular NFT. A copied collection name did not provide the same precision.

Token IDs identify assets inside a contract; transaction hashes identify transactions. The full identifiers preserve that distinction when an interface abbreviates addresses or hashes. Keeping the network context also prevents an Ethereum-compatible address from being mistaken for the same asset on another chain. Similar names or matching token numbers alone cannot establish that relationship.

What did an NFT transfer record establish?

An NFT transfer record established the contract's reported movement of a particular token, within the transaction and block that contained it. An ERC-721 Transfer event contains the from and to addresses together with the token ID. The contract that emitted the event supplied the collection context for that identifier.

A transaction hash identifies the transaction. The NFT event identifies an asset movement within that execution.

Under ERC-721, the zero address in the sender field indicated creation, while the zero address in the recipient field indicated destruction. A transaction's displayed method name alone did not supply the same detail.

A failed transaction could not establish a completed NFT transfer merely because it called a transfer function. Successful execution and the relevant event supported the historical movement. Decoded method names summarized the requested call, while the receipt's status supplied its execution outcome. A transaction identifier alone did not establish success.

The transaction's destination could be an intermediary contract, so it was not necessarily the NFT's receiving wallet. The recipient in the NFT event identified the receiving address for that movement. This distinction also kept the transaction sender separate from the holder whose NFT moved when an authorized operator acted.

Ownership at a recorded block

Ownership views described a particular indexed state, while transfer histories described changes leading to that state. For an ERC-721 token, the owner field concerned that individual identifier. In an ERC-1155 record, the corresponding holding concerned an address's balance for a token ID.

Block numbers placed events within the chain's history. Transaction positions and event-log positions supplied finer ordering when events shared a block. A last visible transfer identified that event's receiving address. For an ERC-721 token, that address was the later owner only if it was not the zero address and no subsequent ownership change occurred. Missing later coverage limited that inference. The archive's last indexed block mattered more than a page's refresh date when interpreting its ownership view.

Transfers, sales and gas amounts

A transfer history recorded asset movement without establishing that every entry represented a purchase. Marketplace execution could combine an NFT movement with payment, while an ordinary transfer could change the holder without a sale. The NFT transfer event itself did not specify a purchase price. A historical trading label needed the payment and marketplace context that justified its classification.

The ETH value attached to a transaction specified the native currency amount for that call. Its gas fee described execution cost, and a payment in another token required its own interpretation. Missing marketplace prices also limited what a collection page could say about trading value. A blank price field did not establish that the NFT had been transferred without payment.

Can NFT history survive a missing image?

NFT transfer history can remain readable when its image is unavailable because event records and media delivery are separate parts of the asset's presentation. An ERC-721 metadata extension may point to descriptive data and an image resource. If that host stops serving the resource, the preview can disappear while indexed transfers remain. A nonstandard contract can also defeat automatic metadata parsing. Neither failure, by itself, establishes that the token was burned.

The withdrawal notice and its NFT limits

The shutdown left a withdrawal service for listed currency balances, with October 20, 2026 stated as the withdrawal deadline. The withdrawal interface listed ETH, WBTC, USDC and USDT for transfers to Ethereum. NFTs were not among the listed withdrawal assets. An NFT's presence in an explorer did not establish eligibility for that currency withdrawal service.

A historical token record could establish what had happened on the retired chain without supplying a route to move that token. The currency deadline also did not promise that archived NFT records would remain accessible until that date or afterward.

Archive coverage and saved records

Archive usefulness depended on the records that a service retained and could interpret. A missing search result could reflect the wrong network context, an unsupported contract or incomplete indexing. It did not alone establish that a token had never existed. A contract-level history and its underlying transaction records offered different coverage from a name search or image preview, so their absences were not interchangeable.

A saved historical record is most useful when it retains the network, full collection address and token ID. The transaction hash and block position keep an event tied to its execution context. Exact identifiers survive changes to display names and shortened labels. Screenshots that preserve only artwork or a collection name lose that connection. A saved record remains bounded by the block range and fields that it actually contains.
