Install dependencies

• Run npm install to install both Ganache-cli and Truffle

Usage

1. Start ganache-cli on port 7545 with npx ganache-cli --port 7545
2. Deploy contracts to local blockchain running npx truffle migrate
3. Execute exploit with npx truffle exec exploits/<filename>

Note: I initially started coding the exploits as Truffle external scripts, that's why most of them are to be executed with npx truffle exec. Another totally valid approach, and somewhat simpler, would be to just build the exploits as Truffle tests. This is what I started doing after Privacy.

ethernaut-ctf's Issues

fallback.exploit.js fails

Hello upon running your exploit, it doesn't get past just prints the attacker address and nothing else. This does not look like the expected outcome. See below for example:

root@kali:~/smart-contracts# npx truffle exec exploits/fallback-exp.js 
Using network 'development'.

Attacker address: 0x33a3eaad2c31b3078ce43add633c393eef1ff6f3

I tried both running by downloading your git repo and running npm install in the root, and by following the instructions directly in your walkthrough. I'm sure that I'm just missing something stupid. I migrated with npx truffle migrate and all the files are created correctly. Ganache-cli is running and truffle-config.js is copied and pasted from the guide.

What could I be doing wrong? Thanks in advance.
