The 0.22 release is a paradigm shift for Hedera Services, as we deliver the next major step in our Smart Contracts 2.0 roadmap on the strength of the protean HIP-25, a technical foundation for scaling the world state of our ledger to billions of entities without sacrificing the high TPS enabled by the hashgraph consensus algorithm.
Highlights of this release include:
- Network EVM capacity increased to 15M
gas-per-second. (Please see HIP-185 for details.) - Gas limit per
ContractCreateorContractCallraised to 4M. - Per-contract storage capacity increased to 10MB.
- Solidity integration with native HTS tokens. (Please see HIP-206 for details.)
We expect more progress in these directions over the coming releases. Do note that the gas usage of the HTS integrations is still evolving; follow this issue to track the finalized gas charges leading up to mainnet release.
There are two other HIP's included in this release not related to the smart contract service. First, HIP-33 enhances queries like CryptoGetInfo with a ledger id that marks which Hedera network answered the query. Second, HIP-31 allows a client to include the expected decimals for a token in a CryptoTransfer. This means a hardware wallet can guarantee its token transactions will have the precision seen by the the user in the device display.
While we are gaining momentum in our smart contracts roadmap, we are also deeply committed to improving the developer experience, and welcome issues and ideas in our GitHub repository and Discord!
