Base mainnet, chain ID 8453base:rpcnone — enforced matrix policy, not measured capacity or runtime publicationAvailability: unavailableValidation: documented
Parameter limits
| JSON path | Frozen limit | Source |
|---|---|---|
| — | unknown | No numeric parameter ceiling is frozen; enforce the declared schema shape and deny an unknown oversized/range profile. |
Historical block retrieval is not an archive-state guarantee. Selectors must be preserved; do not substitute pending, safe, or finalized with latest.
Rate limits and tier
These are enforced product-policy values, not measured upstream capacity or an SLA. Enterprise is finite, never physical “unlimited” capacity.
| Tier | Limit / access | Category |
|---|---|---|
| — | — | No executable tier/RPS profile is frozen. |
See Base limits.
Errors
| Code | Meaning here | Client action |
|---|---|---|
-32601 | Method is deliberately unavailable/not mounted by this frozen contract. | Do not retry as another Base method. |
Authentication/transport failures use the shared client error envelope. See Base errors.
Evidence
- Fixture:
missing— No complete successful correlated request/response pair. - Fixture registry:
infra-4-sety/integration-base/research/R00/import/FIXTURES_INDEX.json. - Evidence boundary: no fixture-backed runtime claim is made.
Limitations
- The accepted freeze prohibits borrowing another network's semantics for this negative row.
- Availability is the frozen baseline, not deployed readiness. documented is the contract floor; evidence_kind retains unknown/source_summary.
