eth_sendPrivateTransaction

Submit a transaction through the candidate private ingress.

Base mainnet, chain ID 8453base:rpcpro — enforced matrix policy, not measured capacity or runtime publicationAvailability: unknownValidation: parser_only

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
Free	— (tier gated)	base_send_private
Basic	— (tier gated)	base_send_private
Pro	on request	base_send_private
Business	on request	base_send_private
Enterprise	on request	base_send_private

See Base limits.

Errors

Code	Meaning here	Client action
`-32602`	Parameters fail the declared schema or upstream parser.	Fix the positional parameters; parser acceptance is not execution success.
`-32003`	The enforced category/provider budget is exhausted.	Honor `Retry-After`; no capacity SLA is implied.
`-32002`	The key is below the enforced minimum tier.	Upgrade only after the capability is runtime-enabled.

Authentication/transport failures use the shared client error envelope. See Base errors.

Evidence

Fixture kind: parser_only.
Fixture source: infra-4-sety/integration-base/research/R00/import/originals/probe/bse_v4t3_private_raw_semantics.json at /cases/0.
Fixture SHA-256: e81df998d300f9f13617430f3235787bf3e3847d77b7fde574f3af71c19a1b5c.
Fixture registry: infra-4-sety/integration-base/research/R00/import/FIXTURES_INDEX.json.
Semantic assertion: Decode body: result:null + error -32600 => one normalized error, never success.
Evidence boundary: Replay only this bounded assertion; no provider calls or original Python execution. Metadata/response fragments can test rejection but cannot prove capability.

Limitations

Raw positional string is only a candidate from parser report; raw vs hash and options unproven.
result+error anomaly raw fixture missing; success return type and privacy guarantees unknown.
No fallback to public; provider forwarding/disclosure contract required.
Availability is the frozen baseline, not deployed readiness. documented is the contract floor; evidence_kind retains unknown/source_summary.
