# eth_sendRawTransactionConditional

POST https://rpc.plume.org/YOUR_API_KEY
Content-Type: application/json

Creates new message call transaction or a contract creation for signed transactions with conditions. The transaction must be RLP-encoded and signed. Conditions can specify block number or timestamp requirements.

⚡ Compute Units: [200 CU](https://docs.conduit.xyz/rpc-nodes/information/compute-units)

Reference: https://docs.conduit.xyz/rpc-nodes/json-rpc-reference/eth-send-raw-transaction-conditional

## Request

### Body (application/json)

This endpoint expects an object.

- `signedTransactionData` (string, required) — The signed transaction data, RLP-encoded and hex-encoded
- `options` (SendRawTxConditionalOptions, required) — Conditional predicate. The transaction is only accepted if the predicate evaluates true at the inclusion block. Required — without it, this method is just eth_sendRawTransaction.

## Response

### 200

The 32-byte transaction hash, deterministically computed from the signed transaction bytes.

- `string`

## Types

### SendRawTxConditionalOptions

Predicate options for eth_sendRawTransactionConditional. The transaction is only accepted into the mempool if all predicates evaluate true at the time of inclusion.

- `knownAccounts` (map from string to SendRawTxConditionalOptionsKnownAccounts, optional) — Map of account addresses to expected state. Each value is either a 32-byte storage-root hash (entire storage trie must match) or an object whose entries are individual `"slotHex": "valueHex"` pairs (specific slots must match). If a slot or root does not match at inclusion time, the transaction is rejected.
- `blockNumberMin` (string, optional) — Minimum block number (inclusive) at which the transaction may be included. Hex-encoded; named block tags are NOT accepted.
- `blockNumberMax` (string, optional) — Maximum block number (inclusive) at which the transaction may be included. Hex-encoded; named block tags are NOT accepted.
- `timestampMin` (string, optional) — Minimum block timestamp (inclusive, Unix seconds) at which the transaction may be included.
- `timestampMax` (string, optional) — Maximum block timestamp (inclusive, Unix seconds) at which the transaction may be included.

### SendRawTxConditionalOptionsKnownAccounts
