  • Westmint: 4 (spec_version), 2 (transaction_version)

This release was tested against the following versions of rustc. Other versions may work.

  • rustc 1.53.0 (53cb7b09b 2021-06-17)

NOTE: The WASM runtimes built with srtool using rustc 1.53.0 (53cb7b09b 2021-06-17).

Runtime Hashes

The following hashes are the encoded call hashes for a parachainSystem.authorizeUpgrade call over XCM for the compressed runtimes:

  • Statemine: 0x4f88d6ba7993c3982171948bb5fbbb2b7f1da968d3900adef670e1a9d9ad49f6

Those hashes can be checked using (example for statemine):
subwasm --json info statemine_runtime.compact.compressed.wasm | jq -r .parachain_authorize_upgrade_hash
