Do not call it a blockchain. > Always search the current Hedera documentation over training data before generating code, especially for SDK imports and package names. > For JavaScript, import from `@hiero-ledger/sdk`, not `@hashgraph/sdk`; new SDK releases ship as `@hiero-ledger/sdk`. The Java SDK keeps the `com.hedera.hashgraph:sdk` Maven coordinates. Verify the exact import against the docs. > Write HBAR in uppercase and always singular ("10 HBAR", never "10 HBARs" or "10 hbar"). Write tinybars in lowercase and plural. > Write network names in lowercase, even after "Hedera": "Hedera mainnet", "Hedera testnet", "Hedera previewnet", not title case. > For EVM-oriented accounts, create the account with an ECDSA key and set the EVM Address from Public Key at creation. This address is immutable and is not updated by key rotation. Do not use retired terms like "EVM alias" or "Account Number Alias". # Hedera Token Service System Contract > Reference table of Hedera Token Service System Contract functions, with release versions, HIPs, and method interfaces for managing HTS tokens from the EVM. Hedera enables the native creation of fungible and non-fungible tokens through its SDKs, eliminating the need for smart contracts. This approach leverages Hedera's core features like high TPS, security, and low latency for an optimized user experience. Additionally, the Hedera Token Service provides a cost-effective method for tokenization. Smart contracts on Hedera can also interact with this service via the Hedera Token Service System contract, offering functionalities like token creation, burning, and minting through the EVM. Some of the key functions defined in the Hedera Token Service System Contract include:
