     1  ## EIP-1559 testing
     2  
     3  This test contains testcases for EIP-1559, which uses an new transaction type and has a new block parameter. 
     4  
     5  ### Prestate
     6  
     7  The alloc portion contains one contract (`0x000000000000000000000000000000000000aaaa`), containing the 
     8  following code: `0x58585454`: `PC; PC; SLOAD; SLOAD`.
     9  
    10  Essentialy, this contract does `SLOAD(0)` and `SLOAD(1)`.
    11  
    12  The alloc also contains some funds on `0xa94f5374fce5edbc8e2a8697c15331677e6ebf0b`. 
    13  
    14  ## Transactions
    15  
    16  There are two transactions, each invokes the contract above. 
    17  
    18  1. EIP-1559 ACL-transaction, which contains the `0x0` slot for `0xaaaa`
    19  2. Legacy transaction
    20  
    21  ## Execution 
    22  
    23  Running it yields: 
    24  ```
    25  $ 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
    26  {"pc":2,"op":84,"gas":"0x48c28","gasCost":"0x834","memory":"0x","memSize":0,"stack":["0x0","0x1"],"returnStack":null,"returnD
    27  ata":"0x","depth":1,"refund":0,"opName":"SLOAD","error":""}
    28  {"pc":3,"op":84,"gas":"0x483f4","gasCost":"0x64","memory":"0x","memSize":0,"stack":["0x0","0x0"],"returnStack":null,"returnDa
    29  ta":"0x","depth":1,"refund":0,"opName":"SLOAD","error":""}
    30  {"pc":2,"op":84,"gas":"0x49cf4","gasCost":"0x834","memory":"0x","memSize":0,"stack":["0x0","0x1"],"returnStack":null,"returnD
    31  ata":"0x","depth":1,"refund":0,"opName":"SLOAD","error":""}
    32  {"pc":3,"op":84,"gas":"0x494c0","gasCost":"0x834","memory":"0x","memSize":0,"stack":["0x0","0x0"],"returnStack":null,"returnD
    33  ata":"0x","depth":1,"refund":0,"opName":"SLOAD","error":""}
    34  ```
    35  
    36  We can also get the post-alloc:
    37  ```
    38  $ dir=./testdata/9 && ./evm t8n --state.fork=London --input.alloc=$dir/alloc.json --input.txs=$dir/txs.json --input.env=$dir/env.json --output.alloc=stdout
    39  {
    40   "alloc": {
    41    "0x000000000000000000000000000000000000aaaa": {
    42     "code": "0x58585454",
    43     "balance": "0x3",
    44     "nonce": "0x1"
    45    },
    46    "0x2adc25665018aa1fe0e6bc666dac8fc2697ff9ba": {
    47     "balance": "0xbfc02677a000"
    48    },
    49    "0xa94f5374fce5edbc8e2a8697c15331677e6ebf0b": {
    50     "balance": "0xff104fcfea7800",
    51     "nonce": "0x2"
    52    }
    53   }
    54  }
    55  ```
    56  
    57  If we try to execute it on older rules: 
    58  ```
    59  dir=./testdata/9 && ./evm t8n --state.fork=Berlin --input.alloc=$dir/alloc.json --input.txs=$dir/txs.json --input.env=$dir/env.json --output.alloc=stdout
    60  ERROR(10): Failed signing transactions: ERROR(10): Tx 0: failed to sign tx: transaction type not supported
    61  ```
    62  
    63  It fails, due to the `evm t8n` cannot sign them in with the given signer. We can bypass that, however, 
    64  by feeding it presigned transactions, located in `txs_signed.json`. 
    65  
    66  ```
    67  dir=./testdata/9 && ./evm t8n --state.fork=Berlin --input.alloc=$dir/alloc.json --input.txs=$dir/txs_signed.json --input.env=$dir/env.json 
    68  INFO [05-07|12:28:42.072] rejected tx                              index=0 hash=b4821e..536819 error="transaction type not supported"
    69  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"

    71  INFO [05-07|12:28:42.073] Wrote file                               file=result.json
    72  ```
    73  
    74  Number `0` is not applicable, and therefore number `1` has wrong nonce, and both are rejected.
