Recover WETH and ETH JUMPDEST #36

Closed SadeRespector closed 1 year ago

SadeRespector commented 1 year ago

Testing the JUMPDEST for recover WETH when using cast send for recover ETH and WETH results in "(code: -32000, message: invalid jump destination, data: None)"

used>> cast send --rpc-url https://goerli.infura.io/v3/7f4a751c20c34aaa81865fc15e95d236 --private-key 0x04d3fA39350C28FD5B192129f3f962C09CA5FCFa 0x41 Error: (code: -32000, message: invalid jump destination, data: None)

read the code dude, you need to encode amt as well. abi.encodePacked(jumpdest, amount)

I was able to recover weth using cast send --rpc-url https://goerli.infura.io/v3/7f4a751c20c34aaa81865fc15e95d236 --private-key 0x04d3fA39350C28FD5B192129f3f962C09CA5FCFa0x37000000000000000000000000000000000000000000000000016345785d8a0000 The documentation says recover weth is used with 0x41 jumpdest, however I was able to successfully recover the weth using 0x37 jumpdest with amount out calculated using ethers to hex function and attatched to the payload. Will close issue when I figure out if recover weth is possible with a different jumpdest.

I will try this as well I was sending raw data and not using abi.encode.

The JUMPDEST for recover ETH is 0x32. I found this by running the test and logging the JUMPDEST returned from the contract SandoCommon.

If you look at the console lines in both of these tests you can see where I got my jumpdest's from. Hope this helps people.
