# WALL•E
Wall•E is a Bitcoin Wallet written in Zig.
> **WARNING**: This is just an attempt to learn Bitcoin and Zig. Do not use this project with real BTC.
#### Run
Run src/main.zig
``` bash
zig build run
```
Run src/p.zig (used for debugging)
``` bash
zig build run-p
```
#### Testing
``` bash
zig build test
zig build test --summary all -- src/bip39/bip39.zig src/bip38/bip38.zig
```
### Dev Environment
See devbox.json
``` bash
devbox shell
```
### Bitcoin Node
Use Dockerfile to run bitcoin node using bitcoin-core. node/bitcoin.conf can be used as bitcoin config to run regtest with rpcuser walle and pwd password.
``` bash
docker build -t btcnode .
docker volume create btcnode
docker run --rm --name btcnode -v btcnode:/bitcoin-25.0/data -p 18444:18443 btcnode
```
For mac users use this code to build docker image.
``` bash
docker build -t btcnode -f Dockerfile.arm .
```
The first time you run the node you need to create a new wallet (it is no longer created automatically, if the walle was already created use loadwallet) then you can getnewaddress.
``` bash
bitcoin-cli -rpcuser=walle -rpcpassword=password -rpcport=18443 createwallet walle
bitcoin-cli -rpcuser=walle -rpcpassword=password -rpcport=18443 getnewaddress
```
Test bitcoin node from outside container:
```bash
curl --verbose -L --user walle --data-binary '{"jsonrpc": "1.0", "id": "walle", "method": "getblockchaininfo", "params": []}' -H 'content-type: text/plain;' 0.0.0.0:18444
```
