We at Tatum have been big fans of for a while now. What’s not to love? Blazing fast transaction times, minimal gas fees, full EVM compatibility, all backed by a fantastic team and a mission statement that we can really get behind: Celo “To build a financial system that creates the conditions for prosperity — for everyone.” We love Celo so much that we’ve built more features for the blockchain than any other we support in our platform. And now, , faster than ever before. We want to make sure any developer — and we really mean ANY developer — can do everything they need to build full-fledged dapps on Celo. We’ve built a suite of tools for creating anything you need using our SDKs and API, and where they really shine is for making cutting-edge dapps in Celo’s thriving NFT ecosystem. we’re partnering with Celo to help more developers build better NFT apps All the NFT Tools You Need So let’s break down exactly what we mean by this. Let’s say you’re a developer with zero blockchain experience who wants to build an NFT app or marketplace. What will you need to do on Celo to make this happen? Your users need a place to hold their NFTs So, you’ll need to create wallets for them. You can easily do that with our SDK or API, but most users won’t want to be bothered with securely storing their private keys. And with , they won’t have to. Tatum Key Management System (KMS) KMS allows you to build full custodial solutions to locally generate wallets, private keys, and deposit addresses, and to securely sign transactions on-premise. . Your users can just log in with their credentials, and KMS takes care of the rest. Security, unlimited scalability, and it’s ready-to-go out of the box Now, how are you going to make those NFTs? Whether you’re allowing your users to mint NFTs, or creating your own collections to sell in your app or marketplace, you’ll need some way to create NFTs. If you do this yourself from scratch, you’ll need to learn Solidity to code your own NFT smart contract. And this will take you A LOT of time and effort to get right. But with Tatum, you can create NFTs without ever learning Solidity. We’ve already created prebuilt smart contracts for you to rapidly deploy, and they’re ready to go with just 1 API call. , and you can easily build NFT features into your app for your end-users to mint their own. You can be up and minting NFTs in minutes instead of months We’ve got ready-to-go , (to create shared-ownership NFTs and other advanced use cases), and even have smart contracts if you want to create your own cryptocurrency on Celo. We’ve also got ready-to-go that record provenance data and can pay percentage royalties to multiple authors in any ERC-20 token you want. But that’s a whole other discussion in and of itself. ERC-721 smart contracts ERC-1155s ERC-20 royalty NFTs Notifications for any token transfer Now that you’ve created your NFT collection, you’ll want to be able to send NFTs to different Celo account addresses. Don’t worry, we’ve got an endpoint for that too. And what’s more, you can also set up — for any kind of token, and for both incoming and outgoing transactions. With just a couple of lines of code, you can instantly notify your users when they receive NFTs, CELO, cUSD, cEUR, cREAL or any other ERC-20 or ERC-1155 tokens. This is normally really difficult, but with Tatum it’s just a matter of 1 API call. webhook notifications for any account address on Celo Instantly look up NFT data Your app’s end-users will definitely want to see the awesome NFTs in their collection, and you can easily let them with our Get NFT metadata endpoint. But that’s just the beginning. You can look up NFTs by token, address, different transactions, and a wide variety of other parameters. You can show your users everything they need and create a seamless NFT app experience on Celo. And That’s Just a Little Taste As we mentioned earlier, we’ve got more features available for Celo than any other platform, and it’s honestly far too much to cover in just one article. But you should really check out our (automatically pay for your users’ gas fees), and all the insane features that come with Tatum’s virtual accounts. instant NFT marketplace smart contracts, gas pump We hope this gives you an idea of the potential, and we hope you’re as excited as we are about building NFT apps on Celo.
