Build information

WASM runtime built using rustc 1.88.0 (6b00bc388 2025-06-23)

⚠️ Breaking Changes ⚠️

• MODEXP calls with base, exponent, or modulus > 1024 bytes will now fail and consume all gas (#3638)
• Transactions with gas limit > 16,777,216 will be rejected at validation (#3638)
• EIP-7883 greatly increases ModExp gas costs, which can lead to smart contract failures. (#3632)
• Many XCM instructions weight increased (#3624)
• Transaction fees may increase for Substrate extrinsics whose weight is dominated by proof_size rather than ref_time. This particularly affects storage-heavy operations. (#3571)
• pallet-xcm-transactor extrinsics setFeePerSecond and removeFeePerSecond are removed. (#3569)
• The DestinationAssetFeePerSecond storage map in pallet-xcm-transactor is removed. (#3569)

Changes

• Improve WeightToFee calculation (#3571)
• [MOON-3323] Refactor XCM Transactor to Delegate Fee Pricing to XCM Weight Trader (#3569)
• Improve multi-delegations requests handling (#3619)
• fix dest_asset_fee_per_second behavior (#3618)
• Add support for Osaka fork (EIP-7939) (#3628)
• Add support for EIP-7883 (#3632)
• Benchmark XCM instructions from polkadot-sdk pallet_xcm_benchmarks (#3624)
• Add support for EIP-7823 and EIP-7825 (#3638)
• Improve get_units_per_second computation (#3648)
• Add handling of MultipleLogs error in pallet-ethereum hooks (#3650)
• update frontier pin (#3654)
• Fix: Preserve beneficiary junction order in split_location_into_chain_part_and_beneficiary (#3649)
• Re-enable UniversalOrigin XCm instruction (#3659)
• Fix benchmarks and XCM refund logic (#3660)
• Generated weights for runtime 4201 (#3665)
