eth_sendUserOperation

Base / https://triport.io/r/{key}/rpc/base

Minimum tier: Pro

Base method guide

Last updated:

Four full EntryPoint addresses recovered from response body. v4 case labels omit eth_ prefix and their request scripts are absent; f30 script uses eth_supportedEntryPoints/eth_estimateUserOperationGas. Cannot promote unprefixed aliases. Two getCode bodies truncated, no deployed code hashes/ABI/UserOperation version or successful lifecycle. Errors prove only arity/hex/field validation. Availability is the frozen baseline, not deployed readiness. documented is the contract floor; evidence_kind retains unknown/source_summary.
