execution-spec-tests-fixtures

Fixtures from the official Ethereum test releases from execution-spec-tests for internal consumption.

Fixtures are separated into two "base" folders:

• stable: Fixtures which are supported to work on latest EthereumJS master branch
• dev: Fixtures for features and/or EIPs which are not yet fully supported (often for a future fork)

Note that this can be distinct from the _develop and _stable releases from the EST repo and orients on the implementation state on the EthereumJS side.

stable Fixtures

Fixtures in stable are taken from the following releases:

• v5.4.0 | Dec 7, 2025 | Osaka + some pre-Osaka tests
  • state_tests/osaka/
  • state_tests/prague/
  • state_tests/cancun/
  • state_tests/shanghai/
  • blockchain_tests/osaka/

Test exclusions (file size limit GitHub):

• blockchain_tests/osaka/eip7934_block_rlp_limit/test_block_at_rlp_size_limit_boundary.json (101 MB)
• blockchain_tests/osaka/eip7934_block_rlp_limit/test_block_rlp_size_at_limit_with_all_typed_transactions.json (168 MB)
• blockchain_tests/osaka/eip7934_block_rlp_limit/test_fork_transition_block_rlp_limit.json (134 MB)

dev Fixtures

The fixtures in dev currently consist of multiple consecutive releases to ease development (different release characteristics):

• bal@v5.1.0 | Jan 30, 2026 | bal-devnet-2 | Various Amsterdam EIPs | BAL definitions included
  • blockchain_tests/amsterdam/v510_mixed_with_other_eips/

  • blockchain_tests/amsterdam/v301_single_bal_no_bal_defs/eip7928_block_level_access_lists/
• bal@v2.0.0 | Dec 12, 2025 | Only EIP-7928 Block Level Access Lists (BAL) | No mixture, BAL definitions, somewhat outdated
