In the 0.24 release of Hedera Services, we are excited to give smart contract developers a new level of interoperability with native Hedera Token Service (HTS) tokens via HIP-218 (Smart Contract interactions with Hedera Token Accounts). The Hedera EVM now exposes every HTS fungible token as an ERC-20 token at the address of the token's 0.0.X entity id; and analogously, every HTS non-fungible token appears as an ERC-721 token. This means a smart contract can look up its balance of a fungible HTS token; or change its behavior based on the owner of a particular HTS NFT. Please see the linked HIP for full details.
This upgrade also creates two new system accounts 0.0.800 and 0.0.801 that will hold reward funds.
One change to the Hedera API (HAPI) is that we now have enough evidence to conclude the experimental getAccountNftInfos and getTokenNftInfos queries do not have a favorable cost/benefit ratio, and these queries are now permanently disabled.
