# Dogecoin Multisig Bridge Test
2+
3+
This folder contains a script to test deposits and withdrawals via the Wormhole testnet guardian's 5-of-7 multisig Dogecoin Delegated Manager Set.
4+
5+
## Testing Artifacts
6+
7+
https://doge-testnet-explorer.qed.me/tx/8d55cbffc83f27ec16fb3da9c550857533169233c6683f8d97986b14b928de81

https://doge-testnet-explorer.qed.me/tx/2916f3063844f0e2721f81041c3dc2ac02790d24ce3a1b31b8c1fb2e908d52c0
9+
10+
## Prerequisites
11+
12+
### Bun
13+
14+
```bash
15+
curl -fsSL https://bun.sh/install | bash
16+
```
17+
18+
### Install Dependencies
19+
20+
```bash
21+
bun ci
22+
```
23+
24+
## Dogecoin Testnet Wallet (dogecoin-keygen.ts)
25+
26+
Generates a Dogecoin testnet keypair with WIF-encoded private key and P2PKH address.
27+
28+
```bash
29+
bun run dogecoin-keygen.ts
30+
```
31+
32+
## Solana Devnet Wallet (solana-keygen.ts)
33+
34+
Generates a Solana devnet keypair.
35+
36+
```bash
37+
bun run solana-keygen.ts
38+
```
39+
40+
Note: As the Delegated Manager Set feature is currently permissioned, in order for this test to work, your Solana devnet address has to be in the allowlist of the running testnet guardian.
41+
42+
## Testnet Deposit Script (deposit-testnet.ts)
43+
44+
Deposits DOGE to a P2SH multisig address controlled by the delegated manager set. The script builds a custom redeem script with embedded metadata (emitter chain, emitter contract, sub-address seed) and creates a 5-of-7 multisig.
45+
46+
### Prerequisites
47+
48+
- `dogecoin-testnet-keypair.json` - Funded Dogecoin wallet (from `dogecoin-keygen.ts`)
49+
- `solana-devnet-keypair.json` - Solana keypair for emitter contract address (from `solana-keygen.ts`)
50+
51+
### Usage
52+
53+
```bash
54+
bun run deposit-testnet.ts
55+
```
56+
57+
## Testnet Withdraw Script (withdraw-testnet.ts)
58+
59+
Withdraws DOGE from the P2SH multisig address back to the original sender. Collects 5-of-7 signatures from the delegated manager set to satisfy the multisig requirement.
60+
61+
### Prerequisites
62+
63+
- `solana-devnet-keypair.json` - Same Solana keypair used for deposit
64+
- `deposit-info.json` - Created by running `deposit.ts`
65+
66+
### Usage
67+
68+
```bash
69+
bun run withdraw-testnet.ts
70+
```
