# Static test case for withdrawals on EL

The following test case was generated by the fuzzer so it looks a bit funky. The genesis block can be created with the following config:

```

```

First we send a FCU with the following parameters:
``` 
FCU

```
Withdrawals are not printed correctly, here they are in pretty printed form:
```

```

The result of the FCU should be 
```
{PayloadStatus:{Status:VALID LatestValidHash:0xfe950635b1bd2a416ff6283b0bbd30176e1b1125ad06fa729da9f3f4c1c61710 ValidationError:<nil>} PayloadID:0xaa310cafae3839f5}
```
Now we call `GetPayload` with `0xaa310cafae3839f5` as the payload id.
Result (withdrawals are not expanded correctly again, just take them from above): 
```

```

Now we call `NewPayload` with the following parameters (withdrawals are not expanded correctly again, just take them from above): 
```
{ParentHash:0xfe950635b1bd2a416ff6283b0bbd30176e1b1125ad06fa729da9f3f4c1c61710 FeeRecipient:0xaa00000000000000000000000000000000000000 StateRoot:0x7f7510a0cb6203f456e34ec3e2ce30d6c5590ded42c10a9cf3f24784119c5afb ReceiptsRoot:0x56e81f171bcc55a6ff8345e692c0f86e5b48e01b996cadc001622fb5e363b421 LogsBloom:[0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0] Random:0xff00000000000000000000000000000000000000000000000000000000000000 Number:1 GasLimit:30000000 GasUsed:0 Timestamp:13 ExtraData:[] BaseFeePerGas:+7 BlockHash:0x2ff774a9940959760d1b98330be6d764a63861e4285871e794ad5542bd38e886 Transactions:[] Withdrawals:[0xc0000ab500 0xc0000ab5f0 0xc0000ab650 0xc0000ab6b0 0xc0000ab740 0xc0000ab7a0 0xc0000ab800 0xc0000ab860]}

```
Which should result in 
```
{Status:VALID LatestValidHash:0x2ff774a9940959760d1b98330be6d764a63861e4285871e794ad5542bd38e886 ValidationError:<nil>}
```
Now we set head to the correctly imported block with fcu: 
```
{HeadBlockHash:0x2ff774a9940959760d1b98330be6d764a63861e4285871e794ad5542bd38e886 SafeBlockHash:0x2ff774a9940959760d1b98330be6d764a63861e4285871e794ad5542bd38e886 FinalizedBlockHash:0x2ff774a9940959760d1b98330be6d764a63861e4285871e794ad5542bd38e886}
<nil>
```
Result:
```
{PayloadStatus:{Status:VALID LatestValidHash:0x2ff774a9940959760d1b98330be6d764a63861e4285871e794ad5542bd38e886 ValidationError:<nil>} PayloadID:<nil>}
```

And the head block should be updated to `0x2ff774a9940959760d1b98330be6d764a63861e4285871e794ad5542bd38e886`
