Release Notes

Klaytn v1.10.2 contains a hardfork upgrade that results in backward-incompatible changes. All Baobab/Cypress nodes would thus have to be upgraded to v1.10.2 or higher before the target block number. The hardfork implements [KIP-103] that is a technical specification of [KGP-6].
The hardfork schedule is as follows:
Baobab Testnet
  • BlockNumber: 119145600 (estimated time: 6 Apr, 4:20 AM UTC+9)
  • Hardfork contents: KIP-103 hardfork (Baobab already applied Kore hardfork)
  • TreasuryRebalance contract address: 0xD5ad6D61Dd87EdabE2332607C328f5cc96aeCB95
Cypress Mainnet
  • BlockNumber: 119750400 (estimated time: 17 Apr, 01:01 AM UTC+9)
  • Hardfork contents: Kore, KIP-103 hardforks
  • TreasuryRebalance contract address: 0xD5ad6D61Dd87EdabE2332607C328f5cc96aeCB95
*You can find detailed information on TreasuryRebalance contract from KIP-103
NOTE: At the activation of KIP-103, the balance of the Treasury account will be changed in an unusual way. You can find the change result on the TreasuryRebalance contract. NOTE: Some APIs (governance_getStakingInfo, klay_getStakingInfo, governance_getRewards) change their returning field names of KGF, KIR to kff, kcf respectively. The old field names will remain before v1.11.0 for backward compatibility.
