Yes. Mnemonic delivers real-time data as soon as it's confirmed on-chain (transactions accepted and blocks confirmed).
The SLA is under 2 minutes.
All of them. We do not pick and choose which collections to support. We index and process all available data such that users get an instant access to all NFTs that have ever been created on the blockchain.
No. Our infrastructure, including blockchain nodes, is fully built and constantly optimized by our team to ensure efficiency and high SLAs.
We get data directly from the blockchain and are operating our own cluster of nodes for redundancy and reliability. The data that we collect includes all historical data, every transaction, event, trace, log and contract from block zero.
We support and decode all major contract standards, which includes, but not limited to ERC20, ERC721, ERC1155 and more. The decoding is typically done in real-time, which means when a new contract is deployed to the blockchain it will be available in our APIs within a couple of minutes.
If you found a contract that is missing or not decoded properly, please submit the request for decoding at https://forms.gle/w9PiG16oJvF3y6BX7.
It will take us between 24-48 hours to review and make changes.

Yes. Full historical data is available for querying.
No. We do not remove or curate data in any way.
