## Test missing basefee
In this test, the `currentBaseFee` is missing from the env portion.
On a live blockchain, the basefee is present in the header, and verified as part of header validation.
In `evm t8n`, we don't have blocks, so it needs to be added in the `env`instead.
When it's missing, an error is expected.
```
dir=./testdata/11 && ./evm t8n --state.fork=London --input.alloc=$dir/alloc.json --input.txs=$dir/txs.json --input.env=$dir/env.json --output.alloc=stdout --output.result=stdout 2>&1>/dev/null
ERROR(3): EIP-1559 config but missing 'currentBaseFee' in env section

## EIP-1559 testing
This test contains testcases for EIP-1559, which uses an new transaction type and has a new block parameter.
### Prestate
The alloc portion contains one contract (`0x000000000000000000000000000000000000aaaa`), containing the
following code: `0x58585454`: `PC; PC; SLOAD; SLOAD`.
Essentialy, this contract does `SLOAD(0)` and `SLOAD(1)`.
The alloc also contains some funds on `0xa94f5374fce5edbc8e2a8697c15331677e6ebf0b`.
## Transactions
There are two transactions, each invokes the contract above.
1. EIP-1559 ACL-transaction, which contains the `0x0` slot for `0xaaaa`
2. Legacy transaction
## Execution
Running it yields:
```
$ dir=./testdata/9 && ./evm t8n --state.fork=London --input.alloc=$dir/alloc.json --input.txs=$dir/txs.json --input.env=$dir/env.json --trace && cat trace-* | grep SLOAD
{"pc":2,"op":84,"gas":"0x48c28","gasCost":"0x834","memory":"0x","memSize":0,"stack":["0x0","0x1"],"returnStack":null,"returnD
ata":"0x","depth":1,"refund":0,"opName":"SLOAD","error":""}

ata":"0x","depth":1,"refund":0,"opName":"SLOAD","error":""}
```
We can also get the post-alloc:
```
$ dir=./testdata/9 && ./evm t8n --state.fork=London --input.alloc=$dir/alloc.json --input.txs=$dir/txs.json --input.env=$dir/env.json --output.alloc=stdout
{
"alloc": {
"0x000000000000000000000000000000000000aaaa": {
"code": "0x58585454",
"balance": "0x3",
"nonce": "0x1"
},
"0x2adc25665018aa1fe0e6bc666dac8fc2697ff9ba": {
"balance": "0xbfc02677a000"
},
"0xa94f5374fce5edbc8e2a8697c15331677e6ebf0b": {
"balance": "0xff104fcfea7800",
"nonce": "0x2"
}
}
}
```
If we try to execute it on older rules:
```
dir=./testdata/9 && ./evm t8n --state.fork=Berlin --input.alloc=$dir/alloc.json --input.txs=$dir/txs.json --input.env=$dir/env.json --output.alloc=stdout
ERROR(10): Failed signing transactions: ERROR(10): Tx 0: failed to sign tx: transaction type not supported
```
It fails, due to the `evm t8n` cannot sign them in with the given signer. We can bypass that, however,
by feeding it presigned transactions, located in `txs_signed.json`.
```
dir=./testdata/9 && ./evm t8n --state.fork=Berlin --input.alloc=$dir/alloc.json --input.txs=$dir/txs_signed.json --input.env=$dir/env.json
INFO [05-07|12:28:42.072] rejected tx index=0 hash=b4821e..536819 error="transaction type not supported"
INFO [05-07|12:28:42.072] rejected tx index=1 hash=a9c6c6..fa4036 from=0xa94f5374Fce5edBC8E2a8697C15331677e6EbF0B error="nonce too high: address 0xa94f5374Fce5edBC8E2a8697C15331677e6EbF0B, tx: 1 state: 0"
INFO [05-07|12:28:42.073] Wrote file file=alloc.json
INFO [05-07|12:28:42.073] Wrote file file=result.json
```
Number `0` is not applicable, and therefore number `1` has wrong nonce, and both are rejected.
