# exo_s1
Build **a cli wallet** that generates a keypair and can handle airdrop/sending sol.
## Install
Install **bun**
`curl -fsSL https://bun.sh/install | bash`
`bun --help`
To install dependencies:
```bash
bun install
```
This project was created using `bun init` in bun v1.1.20. [Bun](https://bun.sh) is a fast all-in-one JavaScript runtime.
If you occure this problem: `bigint: Failed to load bindings, pure JS will be used (try npm run rebuild?)`, resolve it by running the following command `npm rebuild`
## Commands
- `bun run cli.ts wallet --name ` : Create \.wallet.json file, with key pair in it !
- `bun run cli.ts balance --name ` : Get balance of an \ account wallet !
- `bun run cli.ts airdrop --name --amount ` : Get balance of \ SOL for \ account wallet !
- `bun run cli.ts transfer --from --to --amount ` : Transfer \ SOL from \ to \ !
Running local validator : `solana-test-validator --reset`
## Example
```bash
$ bun run cli.ts wallet --name alice
Create Key Pair into "alice.wallet.json" file !

```
```bash
$ bun run cli.ts wallet --name bob
Create Key Pair into "bob.wallet.json" file !
CXzmHbMxx1drjk42hshaP6R6m2i2btLnpm3hZoMMSA9L
```
```bash
$ ls -l *.wallet.json
.rw-rw-r-- 173 franck 25 juil. 21:31 alice.wallet.json
.rw-rw-r-- 173 franck 25 juil. 21:31 bob.wallet.json
```
```bash
$ bun run cli.ts balance --name alice
Get balance from "alice.wallet.json" file !
Balance (alice): 0
```
```bash
$ bun run cli.ts balance --name bob
Get balance from "bob.wallet.json" file !
Balance (bob): 0
```
```bash
$ bun run cli.ts airdrop --name alice --amount 3
Get aidrop to "alice" !
(Please wait few seconds before any other operation...)
```
```bash
$ bun run cli.ts balance --name alice
Get balance from "alice.wallet.json" file !
Balance (alice): 3
```
```bash
$ bun run cli.ts transfer --from alice --to bob --amount 1
Get data (from) "alice" !
8CKNd7tkcYRkcLJfif6yurLp2khfRp6ECvRbunEH85iM
Get data (to) "bob" !

(Please wait few seconds before any other operation...)
```
```bash
$ bun run cli.ts balance --name alice
Get balance from "alice.wallet.json" file !
Balance (alice): 1.999995
```
```bash
$ bun run cli.ts balance --name bob
Get balance from "bob.wallet.json" file !
Balance (bob): 1
```
All the operation has been made on a **local node validator** instead of **devnet**, because of aidrop problems...
By running `solana-test-validator` !
⚠️ Beware it creates local files and directories at the current working directory.
**cli.ts:**
```typescript
const connection = new Connection("http://localhost:8899");
//const connection = new Connection("https://api.devnet.solana.com");
```
