@ARR552 Can you share the cmd used to start anvil? And also the chain-id of the anvil instance

[ARR552]

@yash-atreya This is the command:

anvil --block-time 1 --slots-in-an-epoch 1 --chain-id 271828 --host 0.0.0.0 --port  33268 --dump-state ./state_out.json --balance 1000000000" --mnemonic "<mnemonic>"

[grandizzy]

@ARR552 thank you, this is similar with #10444 which was solved in #10503
Please foundryup for latest stable version, reopen if still an issue. Thank you
