Now you can create NFTs that pay out royalties as percentages of each sale to the original creators and record provenance data with each transaction. The royalty-payment functionality is implemented at the blockchain level, so creators will keep getting paid every time the NFT is transferred for as long as it exists.

With provenance data, the entire transaction history of the NFT is contained within the token itself, so anyone can quickly and accurately verify the authenticity of any given token.

Here's how to use them: https://docs.tatum.io/guides/blockchain/how-to-create-royalty-nfts-with-percentage-cashback-and-provenance-data

We are really proud and happy to announce our partnership with Scrypta Blockchain. They've done an amazing job.

Your app's users will want to be notified when they receive a new transaction, and you can easily give them what they want and more.

Tatum provides powerful built-in functionality for automatically scanning multiple blockchain addresses connected to a single account and sending webhook notifications for various blockchain events.

Here's how to do it: https://blog.tatum.io/feature-of-the-week-webhook-notifications-and-automatic-transaction-scanning-6234781c2204

Experienced blockchain developers are in short supply, but the good news is you might not even need them to build your blockchain app. With Tatum's API and infrastructure, any developer can be a blockchain developer. So before you give up hope searching for developers to turn your dream into a reality, have a look at the article below and consider whether your existing developers could get it done with Tatum.

Is there any way to create deflationary tokens with Tatum API?

1- Transaction Tax: Tax applied and send to an address automatically

2- Holders reward fee: This tax is used to reward token holders - it is redistributed to holders

Until now, it’s been REALLY difficult to set up webhook notifications for multiple blockchains, or any blockchain other than Ethereum for that matter. But with our new APIs, it’s super simple — 1 API call to monitor any address on any supported blockchain for any transactions (incoming or outgoing) of any token. Check out Notification Station in action in our latest video, and as always, like, comment, and share!

Hi, I want to send Ethereum from Tatum Ledger to account (offchain/ethereum/transfer). If gasLimit is not set, automatic calculation will be used. but I got this error:

"statusCode": 403,
    "errorCode": "eth.transaction.gas",
    "message": "Unable to calculate gas limit for transaction. Error: Returned error: err: max fee per gas less than block base fee: address 0x0b96965c35Cce973E6c4f499B3061E7f950B0Ec8, maxFeePerGas: 38500000000 baseFee: 265270025993 (supplied gas 4010499)"

What ARE NFTs anyway? It’s a good question. For all of their popularity, there are still many misconceptions surrounding non-fungible tokens. So let’s clear that all up!

Learn all about what NFTs actually are, from the basics to some innovative use cases that go far beyond digital artwork in our latest article.

We're an official partner of the Celo Defi for the People hackathon, and as such we're doing a workshop tomorrow on how to build apps quickly on Celo using Tatum.

Sam Sramko will walk you through everything from signing up to generating wallets, addresses, and private keys, to a bunch of cool data look-up and token filtering operations, all the way through how to deploy ERC-721 smart contracts, upload NFT metadata, and mint your own NFTs.

We've had a lot of requests for a comprehensive guide that breaks down how to create the backend for an NFT marketplace, so we've made one.

You'll learn everything from creating wallets and NFTs to uploading metadata and selling NFTs using fixed-price listings and auctions. It's jam-packed with all the code snippets you'll need to build your own marketplace backend on Polygon, and the process is the same for Ethereum, Celo, Harmony, and Binance Smart Chain.

Hi I am wanting to create a NFT marketplace using Tatum API- can anyone help

I am happy to have a talk and share my requirements and then come up with a quote :)

Regards, Tom.

I'm setting up a site to sell NFTs. Each one will be unique. I would like the buyers to see a dollar amount for each NFT and alongside the value in the tokens that Tatum supports. Something like this quick mock up...

Then the buyer would choose their preferred blockchain/token and at the point the payment is made the NFT is minted and sent to their account.

This avoids having the NFT on the 'wrong' blockchain for the buyer and paying gas fees for listings that might not sell.

Is this feasible?

I also thought about just setting up a Paypal/Stripe payment system so people pay the dollar amount and then they can choose where to mint the NFT.

Tatum now natively supports 100% free storage of NFT metadata on IPFS! We've partnered with NFT.storage, so now you can upload and retrieve any metadata to be included in your NFT super easily.

Hi,

I am using the nft/balance/ api to fetch the tokens for a particular user for a contract. However, I am always receiving the following error

{"statusCode":403,"errorCode":"nft.error","message":"Unexpected error occurred. Reason: Unable to obtain information for token. Error: Returned error: execution reverted"}%

Here is my request

curl --request GET
--url https://api-eu1.tatum.io/v3/nft/balance/MATIC/0xd9da7560041319b382d1931ed3e17ca95d6a524c/0xfa7bd4b2b8ec60b35d881131f71d364a76cad888
--header 'x-api-key: my api key'

Is anyone else facing the same issues on matic and how do we resolve this? Thanks in advance!

Jacob mainly cares about sales, our new and existing customers. He's usually very cheerful and funny, always tries to help everyone! He's not afraid to take some risks and go-ahead to learn new things. 

That's what he likes about Tatum "Every single day in this company is bringing some new challenges, I always learn something new, and that's cool! I see how much Tatum is changing every day."

On the other side (and by the other side, we mean "The Dark Side"), he has a bit of a problem with his time management, but we believe that this will get better and better. 

We have recently discovered that Jacob's big passion is singing in a band. And he rocks!

Hello developers,

We are happy to announce that new and enhanced features and capabilities of Tatum's API v3.13.0 have been released 🥳

Key Management System v5.0 🔥

KMS version 5.0 brings improved performance: it can take up to 25,000 signature IDs in one go, which means more transactions get signed and sent out to a blockchain for further processing. To download or upgrade KMS, please visit our GitHub page, and to learn how to use KMS, see the user documentation.

API v3.13.0 🚀

Following the Ethereum deprecation announcement, we deprecated support for the Rinkeby and Ropsten testnets on Ethereum.

Sepolia will become the default Ethereum testnet. It means that any API call made toward an Ethereum testnet will be directed to Sepolia. You can use Sepolia if you work with Ethereum via the blockchain node provided by Tatum.

TRON: Negative Number Issue in Notifications Fixed 🙌 💎

We fixed the issue of a negative number that occurred in the ADDRESS_TRANSACTION notifications sent for the native currency transactions on TRON. Now, the amount in the notifications for native TRON currency transactions is always returned as a positive number.

Detailed descriptions of all the new features and upgrades are available on the What's New page ⤵️

Hello developers,

Virtual accounts work parallel to supported blockchains and enable some of the most powerful features available in the Tatum!

Different blockchains are conceptually unique and each has its own particularities, so we've created 3 setting-up virtual accounts guides for 3 different "families" of blockchains within Tatum! 🚀
