feat: add Mint Club V2 action provider
Add action provider for Mint Club V2 bonding curve protocol on Base. Actions: - get_token_info: Token details and bonding curve information - get_token_price: Current price in reserve tokens and USD - buy_token: Mint tokens via bonding curve - sell_token: Burn tokens via bonding curve - create_token: Create new token with bonding curve Uses viem for direct contract interaction with MCV2_Bond. Includes auto ERC20 approval, slippage protection, and USD pricing via 1inch Spot Price Aggregator. Docs: https://docs.mint.club Protocol: https://mint.club

# Mint Club V2 Action Provider
2+
3+
This directory contains the **MintclubActionProvider** implementation, which provides actions to interact with the **Mint Club V2 protocol** on Base mainnet.
4+
5+
## Directory Structure
6+
7+
```
8+
mintclub/
9+
├── mintclubActionProvider.ts # Main provider with Mint Club V2 functionality
10+
├── mintclubActionProvider.test.ts # Test file for Mint Club provider
11+
├── constants.ts # Mint Club contract constants and ABIs
12+
├── schemas.ts # Mint Club action schemas

```
17+
18+
## Actions
19+
20+
- `get_token_info`: Get detailed information about a Mint Club token including bonding curve details
21+
- `get_token_price`: Get the current price of a Mint Club token in reserve tokens and USD
22+
- `buy_token`: Buy Mint Club tokens via the bonding curve mechanism
23+
- `sell_token`: Sell Mint Club tokens via the bonding curve mechanism
24+
- `create_token`: Create a new Mint Club token with bonding curve
25+
26+
## Adding New Actions
27+
28+
To add new Mint Club actions:
29+
30+
1. Define your action schema in `schemas.ts`
31+
2. Implement the action in `mintclubActionProvider.ts`
32+
3. Add tests in `mintclubActionProvider.test.ts`
33+
34+
## Network Support
35+
36+
The Mint Club provider supports Base mainnet only.
37+
38+
## Notes
39+
40+
Mint Club V2 is a bonding curve token protocol that allows anyone to create tokens backed by reserve assets. The protocol uses mathematical curves to determine token prices based on supply and demand.
41+
42+
For more information on the **Mint Club V2 protocol**, visit [Mint Club Documentation](https://mint.club/).
