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.
- ACL-transaction, which contains some non-used slots
- Regular transaction
- ACL-transaction, which contains the slots

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"}
Similarly, 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
