# Reth Amsterdam spec-conformance review — access blocked

Status: incomplete. No candidate bugs or conformance conclusions are reported. This is an access-failure record, not a clean review.

## Pins

No commit pins could be obtained. The mandatory request to https://api.github.com/repos/paradigmxyz/reth/commits/main failed through both Node fetch and curl with the tool error:

> Network access to "api.github.com" was blocked: local/private network addresses are blocked by the sandbox policy.

Consequently no newest-main hash, source line citation, implementation version, or spec version can be asserted. The requested execution-specs forks/bogota and Geth master pins were not obtained either. No substitute hashes were used.

## Candidates

None established. No implementation source was read; absence of findings provides no evidence that the implementation conforms. There was no basis for candidate disproof or severity assessment. No network or node execution tests were performed.

## Requested rules: verification status

The following is the requested review scope, not independently verified specification text.

| EIP | Rules requiring review | Outcome |
| --- | --- | --- |
| 7843 SLOTNUM | Opcode 0x4B, header slot_number, gas 2, pre-Amsterdam invalidity; header RLP field, payload-attribute agreement and first-Amsterdam-block value | Unverified: public sources inaccessible; no file/line available |
| 7954 max contract size | Code/init-code limits 0x10000/0x20000; CREATE, CREATE2, transaction creation, code deposit, init-code word gas, exact-limit behavior, EIP-7702 delegation | Unverified: public sources inaccessible; no file/line available |
| 8024 SWAPN, DUPN, EXCHANGE | Opcodes 0xE6/0xE7/0xE8; immediate decoding; stack underflow/1024 overflow; missing immediate; gas 3; jumpdest scanning; fork gating | Unverified: public sources inaccessible; no file/line available |

No rule was established as correct. The Glamsterdam scheduled-EIP list and current spec revisions were also not established.

## Known-check

Not performed: no candidates were established and public sources were inaccessible. No issue or PR is labeled “known” or “not found”; those labels would imply searches that did not occur. Reth open/closed issue and PR queries by EIP number and short name, execution-specs Test Release Tracker issues, and public Glamsterdam test results remain unchecked. No claims about test coverage or passing results are made.

## URLs attempted and access evidence

No public page contents were successfully read.

| Attempted URL | Observed result |
| --- | --- |
| https://api.github.com/repos/paradigmxyz/reth/commits/main | Sandbox network denial quoted above, using both Node fetch and curl |
| https://raw.githubusercontent.com/paradigmxyz/reth/main/Cargo.toml | curl HEAD: CONNECT tunnel failed, HTTP 403, x-proxy-error: blocked-by-allowlist |
| https://eips.ethereum.org/EIPS/eip-7843 | curl HEAD: CONNECT tunnel failed, HTTP 403, x-proxy-error: blocked-by-allowlist |
| https://hive.ethpandaops.io/glamsterdam/listing.jsonl | curl HEAD: CONNECT tunnel failed, HTTP 403, x-proxy-error: blocked-by-allowlist |

The remaining requested EIP pages, execution-specs Amsterdam files, Geth code and public issue searches were not read. Completing the review requires an environment able to retrieve the named public sources. This machine-level failure is recorded without requesting requester-specific values.
