Ethereum supports native ETH burning via mechanisms like , but Hedera takes a different approach. The native HBAR token cannot be burned. Instead, developers can use the Hedera Token Service (HTS) to create and manage custom tokens with built-in minting and burning capabilities.
Supply Key
Controls minting and burning of tokens.
Must be securely managed to prevent unauthorized actions.
HTS System Contract
System contract functions accessible via reserved address 0x167
.
Enable token creation, minting, and burning directly from Solidity contracts.
Access Control
Only addresses authorized by the supply key can mint or burn tokens.
Multi-signature (multi-sig) or threshold key configurations can enhance security.
Minting Tokens: Introduce new tokens for incentives, rewards, or liquidity.
Burning Tokens: Remove tokens to increase scarcity or meet regulatory requirements.
Important Notes
Ensure the caller holds the supply key.
Associate the treasury account with the token for successful operations.
Minting and burning fail without proper key authorization.
