## Field reference

### Header fields

| Field | Description |
|---|---|
| `header.account` | Sender's public key (prefixed `01` or `02`) |
| `header.timestamp` | ISO 8601 submission time |
| `header.ttl` | Time-to-live string: `"30m"`, `"1h"`, `"1day"` |
| `header.chain_name` | `"casper"` (mainnet) or `"casper-test"` |

### Session types

The `session` field is a tagged union indicating what the deploy does:

| Tag | Meaning |
|---|---|
| `Transfer` | Native CSPR transfer |
| `StoredContractByHash` | Call a contract by hash |
| `StoredContractByName` | Call a named contract |
| `ModuleBytes` | Deploy/run raw Wasm |
| `StoredVersionedContractByHash` | Call a versioned contract |

### CLValue args encoding

Each argument in `args` is a 2-element array `[name, value]` where the value has:
- `cl_type` - the CL type (`"U512"`, `"Key"`, `{ "Option": "U64" }`, etc.)
- `bytes` - hex-encoded byte representation
- `parsed` - human-readable parsed value (string for large integers)

:::note
Amounts like `"15999900000000"` are **motes** (1 CSPR = 1,000,000,000 motes). This value is ~16,000 CSPR.
:::

### Execution result

The `execution_results` array contains one entry per block that included this deploy (usually one).

| Field | Description |
|---|---|
| `block_hash` | Block where this was executed |
| `result.Success.cost` | Total cost in motes (`gas_consumed × gas_price`) |
| `result.Success.transfers` | Transfer record keys created |
| `result.Failure.error_message` | Error if execution failed |

:::note
**Gas vs cost:** `cost` is measured in motes (payment currency). Gas is the internal execution unit - the runtime counts opcodes as gas, then multiplies by the block's `current_gas_price` to arrive at the mote cost. On Casper 1.x the `gas_price` was always `1`, so gas and mote cost were equal.
:::

### Transforms

The `effect.transforms` array records every state change:

| Transform type | Meaning |
|---|---|
| `"Identity"` | Value was read (no change) |
| `{ "WriteCLValue": {...} }` | Balance or storage written |
| `{ "AddUInt512": "..." }` | Amount added to a purse |
| `{ "WriteTransfer": {...} }` | Transfer record created |
| `{ "WriteDeployInfo": {...} }` | Deploy metadata written |

### WriteTransfer fields

| Field | Description |
|---|---|
| `from` | Sender account hash |
| `to` | Recipient account hash |
| `source` | Sender's purse URef |
| `target` | Recipient's purse URef |
| `amount` | Transferred amount in motes |
| `deploy_hash` | Hash of the deploy that caused this transfer |
| `id` | Optional memo ID |

## SDK usage

```ts
const result = await rpcClient.getTransactionByDeployHash(
  '84ad4a6aa15ac60810c854f8463fa83f1fecd1f4ec51088cd22baf7da47bbdf5'
);

const exec = result.executionInfo?.executionResult;

if (!exec?.errorMessage) {
  console.log('Success, gas used:', exec?.consumed);

  // Access transfer details from transforms
  const transfers = exec?.transfers ?? [];
  transfers.forEach(t => console.log('Transfer key:', t));
} else {
  console.log('Failed:', exec.errorMessage);
}

// Initiator public key
console.log(result.executionInfo?.executionResult.initiator.publicKey?.toHex());
```
