Ethereum errors
Ethereum methods return upstream errors in the standard JSON-RPC
{jsonrpc,id,error} envelope. Triport's own product errors (auth, tier, rate
limit) are plain HTTP responses decided before the RPC layer — see the
shared error reference.
Endpoint and plans: Ethereum RPC endpoint.
Notable method-page behavior:
admin_*andpersonal_*methods are intentionally not part of the product, so the gate rejects them with HTTP403method_unknownbefore they reach a node;- premium
debug_*,trace_*, bundle, proof, and txpool methods return HTTP403tier_insufficientbelow their required tier; - category exhaustion returns HTTP
429rate_limited; honorRetry-Afterbefore retrying; - EVM execution failures may include a revert reason in the upstream error or result. They are distinct from authentication and tier errors.
