Question 1

What does Tatum do?

Accepted Answer

Tatum is a blockchain-as-a-service platform providing a unified REST API that enables developers to interact with over 100 blockchain networks — including Bitcoin, Ethereum, BNB Chain, Tron, Solana, Polygon, Cardano, XRP, Dogecoin, and dozens more — through a single consistent API structure. Rather than learning the specific RPC interfaces, SDK libraries, and node management requirements for each blockchain, Nigerian developers using Tatum interact with every chain through the same endpoint patterns. This dramatically reduces the time required to build multi-chain cryptocurrency wallets, exchanges, and payment systems.

Nigeria's position as Africa's largest crypto market means Nigerian developers frequently need to support multiple blockchains simultaneously. Nigerian users hold Bitcoin as a store of value, USDT on Tron for cheap transfers, Ethereum for DeFi access, and BNB Chain for affordable trading. A wallet application serving Nigerian users must support all of these chains. Without Tatum, building multi-chain support means separate integrations for each blockchain — different RPC formats, different transaction structures, different fee models, different SDK libraries. With Tatum, one API key and one consistent REST interface handles everything.

Wallet generation through Tatum creates HD (hierarchical deterministic) wallets with master private keys and extended public keys for any supported blockchain. From a single mnemonic, developers can derive unlimited individual receiving addresses — the standard architecture for exchange and custodial wallet systems that need unique deposit addresses per user. Tatum handles the cryptographic complexity of key derivation for every chain, while the developer retains and stores the private key material securely.

The Virtual Account system is Tatum's most powerful feature for exchange and wallet builders. Virtual accounts are an off-chain ledger system where user balances are tracked in Tatum's database rather than on the blockchain for every small transaction. Users can transfer balances between each other instantly and for free off-chain, while actual blockchain settlements happen in batches or when users withdraw. This is the architecture behind centralized exchanges — and Tatum makes it available to Nigerian exchange operators without building custom ledger infrastructure.

Transaction broadcasting covers the full lifecycle: constructing a signed transaction (Tatum generates the raw transaction with correct nonce, gas, and fee parameters), signing it with the wallet's private key, and broadcasting it to the blockchain network. For Bitcoin, this means handling UTXO selection and change address management. For Ethereum, this means nonce management and gas estimation. Tatum abstracts all chain-specific mechanics.

NFT operations include minting, transferring, burning, and querying NFTs across EVM chains and Solana. Nigerian NFT platforms can mint collections programmatically by calling Tatum's NFT API rather than deploying and managing smart contracts directly. Token operations support creating ERC-20 / BEP-20 tokens, transferring them, and checking balances — all through REST API calls.

Webhook notifications alert Nigerian backend servers when specific blockchain events occur: incoming transactions to monitored addresses, transaction confirmations, NFT transfers, and smart contract events. This enables Nigerian exchanges and payment processors to detect deposits automatically without polling the blockchain.

The free tier with 1 million credits per month and 5 requests per second is sufficient for Nigerian projects in early stages. Paid plans scale from $79/month to $599/month with higher throughput, and enterprise plans provide dedicated infrastructure with SLA guarantees for production Nigerian exchanges and fintech platforms.

Question 2

How much does Tatum cost?

Accepted Answer

Tatum is free to start, with paid tiers for higher usage (freemium). Free: 5 req/sec, 1M credits/month. Paid plans from $79/mo (10 req/sec) to $599/mo. Enterprise custom.

Question 7

Is there anything else I should know before integrating Tatum?

Accepted Answer

Tatum is a blockchain-as-a-service platform offering a unified REST API for 100+ chains. Includes wallet management, transaction broadcasting, NFT operations, DeFi interactions, and virtual account system for off-chain ledger management.
