# defi-skills

Turns a sentence like “supply 100 USDC to Aave” into unsigned DeFi transactions. Useful when an agent must build calldata but never touches your keys.

## What it does

The plugin resolves human-readable inputs — token symbols, ENS names, decimal amounts — and returns ABI-encoded calldata. Under the hood it runs on playbooks: JSON files that describe a protocol's actions, parameters and ABI mappings, with contract addresses kept per chain in `data/chains/{chain_id}/{protocol}.json`. The engine itself holds no protocol-specific code.

Two modes share one pipeline. `build` is deterministic and needs no LLM: `defi-skills build --action aave_supply --args '{"asset":"USDC","amount":"500"}' --json`. The `chat` mode adds an interactive agent and requires `ANTHROPIC_API_KEY`. Output is always `{chain_id, to, value, data}`. Signing and broadcasting stay with your wallet, since the tool does neither and never handles private keys.

Set `WALLET_ADDRESS` for every command. On-chain quotes, ENS lookups and balance queries need `ALCHEMY_API_KEY` with the chains enabled in your Alchemy dashboard; token discovery on Arbitrum, Base, Optimism and Polygon needs `ONEINCH_API_KEY`. Gas and nonce are not estimated here. Swaps are single-hop only.

## Install

### Claude Code (native platform)

**Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin marketplace add anthropics/claude-plugins-community
```
In the agent chat (not a shell):
```text
/plugin install defi-skills@claude-community
```

## When to use it
- build Aave supply calldata from readable parameters
- hand an unsigned transaction to a wallet for signing
- swap tokens on Uniswap V3 without hand-coding ABI
- stake ETH in Lido and get a ready payload
- scaffold a new protocol through the playbook generator

## Example prompts
- Supply 100 USDC to Aave on mainnet and show the unsigned transaction
- Build a swap of 0.5 ETH for USDC on Uniswap
- Stake 5 ETH on Lido and return the calldata as JSON

Translate natural language into unsigned DeFi transaction payloads. A data-driven playbook engine resolves human-readable parameters (token symbols, ENS names, decimal amounts) into ABI-encoded calldata, with zero protocol-specific code in the engine.

### Give your agent DeFi superpowers

**Claude Code:**
```
/plugin marketplace add NethermindEth/defi-skills
/plugin install defi-skills@nethermind-defi-skills
```

**OpenClaw:**
```
npx clawhub install defi-skills
```

That's it. Your agent can now build DeFi transactions:

> *"Supply 100 USDC to Aave"* · *"Swap 0.5 ETH for USDC on Uniswap"* · *"Stake 5 ETH on Lido"*

## Install

```bash
pip install defi-skills
```

Or from source:

```bash
git clone https://github.com/NethermindEth/defi-skills
cd defi-skills
python3 -m venv .venv && source .venv/bin/activate
pip install -e .
```

## Quick Start

```bash
defi-skills config setup                  # interactive wizard
defi-skills actions                       # list all actions
defi-skills actions --chain-id 11155111   # list Sepolia actions
```

Build unsigned transactions (fully deterministic, no LLM requierd):

```bash
# Mainnet
defi-skills build --action aave_supply --args '{"asset":"USDC","amount":"500"}' --json

# Sepolia
defi-skills build --action aave_supply --args '{"asset":"WETH","amount":"1"}' --chain-id 11155111 --json

# More examples
defi-skills build --action uniswap_swap --args '{"asset_in":"WETH","asset_out":"USDC","amount":"0.5"}' --json
defi-skills build --action lido_stake --args '{"amount":"5"}' --json
defi-skills build --action weth_wrap --args '{"amount":"2"}' --json
```

Interactive chat mode (requires LLM API key):

```bash
defi-skills chat
```

## Output

```json
{
  "success": true,
  "transactions": [
    {
      "type": "approval",
      "raw_tx": { "chain_id": 1, "to": "0xA0b8...", "value": "0", "data": "0x095ea7b3..." }
    },
    {
      "type": "action",
      "action": "aave_supply",
      "function_name": "supply",
      "raw_tx": { "chain_id": 1, "to": "0x8787...", "value": "0", "data": "0x617ba037..." }
    }
  ]
}
```

Each `raw_tx` contains `{chain_id, to, value, data}` -- everything needed to sign and broadcast. The tool never signs or broadcasts. Gas estimation and nonce management are left to the signing wallet.
