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 (https://github.com/moonbeam-foundation/moonbeam/pull/3638)
• Transactions with gas limit > 16,777,216 will be rejected at validation (https://github.com/moonbeam-foundation/moonbeam/pull/3638)
• EIP-7883 greatly increases ModExp gas costs, which can lead to smart contract failures. (https://github.com/moonbeam-foundation/moonbeam/pull/3632)
• Many XCM instructions weight increased (https://github.com/moonbeam-foundation/moonbeam/pull/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. (https://github.com/moonbeam-foundation/moonbeam/pull/3571)
• pallet-xcm-transactor extrinsics setFeePerSecond and removeFeePerSecond are removed. (#3569)
• The DestinationAssetFeePerSecond storage map in pallet-xcm-transactor is removed. (#3569)
