EIP-2930 testing

This test contains testcases for EIP-2930, which uses transactions with access lists.

Prestate

The alloc portion contains one contract (0x000000000000000000000000000000000000aaaa), containing the following code: 0x5854505854: PC ;SLOAD; POP; PC; SLOAD.

Essentially, this contract does SLOAD(0) and SLOAD(3).

The alloc also contains some funds on 0xa94f5374fce5edbc8e2a8697c15331677e6ebf0b.

Transactions

There are three transactions, each invokes the contract above.

  1. ACL-transaction, which contains some non-used slots
  2. Regular transaction
  3. ACL-transaction, which contains the slots 1 and 3 in 0x000000000000000000000000000000000000aaaa

Execution

Running it yields:

dir=./testdata/8 && ./evm t8n --state.fork=Berlin --input.alloc=$dir/alloc.json --input.txs=$dir/txs.json --input.env=$dir/env.json --trace 2>/dev/null && cat trace-* | grep SLOAD
{"pc":1,"op":84,"gas":"0x484be","gasCost":"0x834","memSize":0,"stack":["0x0"],"depth":1,"refund":0,"opName":"SLOAD"}
{"pc":4,"op":84,"gas":"0x47c86","gasCost":"0x834","memSize":0,"stack":["0x3"],"depth":1,"refund":0,"opName":"SLOAD"}
{"pc":1,"op":84,"gas":"0x49cf6","gasCost":"0x834","memSize":0,"stack":["0x0"],"depth":1,"refund":0,"opName":"SLOAD"}
{"pc":4,"op":84,"gas":"0x494be","gasCost":"0x834","memSize":0,"stack":["0x3"],"depth":1,"refund":0,"opName":"SLOAD"}
{"pc":1,"op":84,"gas":"0x484be","gasCost":"0x64","memSize":0,"stack":["0x0"],"depth":1,"refund":0,"opName":"SLOAD"}
{"pc":4,"op":84,"gas":"0x48456","gasCost":"0x64","memSize":0,"stack":["0x3"],"depth":1,"refund":0,"opName":"SLOAD"}

Simlarly, we can provide the input transactions via stdin instead of as file:

$ dir=./testdata/8 \
  && cat $dir/txs.json | jq "{txs: .}" \
  | ./evm t8n --state.fork=Berlin \
     --input.alloc=$dir/alloc.json \
     --input.txs=stdin \
     --input.env=$dir/env.json \
     --trace  \
     2>/dev/null \
  && cat trace-* | grep SLOAD
{"pc":1,"op":84,"gas":"0x484be","gasCost":"0x834","memSize":0,"stack":["0x0"],"depth":1,"refund":0,"opName":"SLOAD"}
{"pc":4,"op":84,"gas":"0x47c86","gasCost":"0x834","memSize":0,"stack":["0x3"],"depth":1,"refund":0,"opName":"SLOAD"}
{"pc":1,"op":84,"gas":"0x49cf6","gasCost":"0x834","memSize":0,"stack":["0x0"],"depth":1,"refund":0,"opName":"SLOAD"}
{"pc":4,"op":84,"gas":"0x494be","gasCost":"0x834","memSize":0,"stack":["0x3"],"depth":1,"refund":0,"opName":"SLOAD"}
{"pc":1,"op":84,"gas":"0x484be","gasCost":"0x64","memSize":0,"stack":["0x0"],"depth":1,"refund":0,"opName":"SLOAD"}
{"pc":4,"op":84,"gas":"0x48456","gasCost":"0x64","memSize":0,"stack":["0x3"],"depth":1,"refund":0,"opName":"SLOAD"}

If we try to execute it on older rules:

$ dir=./testdata/8 && ./evm t8n --state.fork=Istanbul --input.alloc=$dir/alloc.json --input.txs=$dir/txs.json --input.env=$dir/env.json 
ERROR(10): failed signing transactions: ERROR(10): tx 0: failed to sign tx: transaction type not supported
