## What it does

This skill connects agent workflows directly to the `nansen trade` command group. Swapping follows a two-step pattern: fetching a quote via `nansen trade quote` and broadcasting it with `nansen trade execute`. A `--dry-run` flag lets the agent inspect routes, approvals, and fees via public RPC calls without consuming quotes or unlocking keys.

Transactions require the `nansen-cli` binary, an initialized wallet from `nansen wallet create`, and the `NANSEN_WALLET_PASSWORD` environment variable alongside `NANSEN_API_KEY`. Cross-chain operations also demand native gas on the originating chain to cover transaction submission.

Arbitrary token-to-token trades are rejected by design. Every swap requires either `USDC` or the native asset (`SOL` on Solana, `ETH` on Base) on at least one leg.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add nansen-ai/nansen-cli --skill nansen-trading -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/nansen-trading/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/nansen-trading/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add nansen-ai/nansen-cli --skill nansen-trading -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/nansen-trading/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add nansen-ai/nansen-cli --skill nansen-trading -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/nansen-trading/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install nansen-ai/nansen-cli nansen-trading
```

2. **Manually: put the files in place**
- File: `.github/skills/nansen-trading/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add nansen-ai/nansen-cli --skill nansen-trading -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/nansen-ai/nansen-cli --path skills/nansen-trading
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/nansen-trading/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add nansen-ai/nansen-cli --skill nansen-trading -a opencode
```

### Claude.ai

**Claude.ai**

## When to use it
- fetch DEX swap quotes across Solana and Base
- bridge tokens across Base and Solana networks
- manage Solana limit orders directly from the terminal
- simulate trade execution and approvals without signing

## Example prompts
- Get a quote to swap 50 USD worth of SOL to USDC on solana
- Execute trade for quote abc-123 with --dry-run
- Create a Solana limit order to sell 1.5 SOL for USDC when price drops below 80

## Authentication

Nansen account API calls accept a selected `nansen:api` browser session or conventional API key with the same permissions. `NANSEN_API_KEY` takes precedence; optional `primaryEnv` preserves configured-key injection. Run `nansen auth status` for offline selection. Cached access expiry alone permits automatic renewal during an authorized task. Stop on anonymous selection, invalid state, blocked/uncertain renewal or actual auth failure; never drop a credential or fall back to anonymous x402 payment. Browser login does not grant wallet signing, privileged service identity or a persistent MCP integration key. Preserve all confirmation, signing, sanctions and geographic checks below. Browser login is available in CLI 2.0.0 within the [macOS arm64 preview scope](https://github.com/nansen-ai/nansen-cli/blob/main/docs/browser-login.md#preview-platform-scope).



# Trade

Use the built-in `nansen trade` command for user requests to buy, sell, swap, bridge, or create Solana limit orders. Prefer this first-class Nansen CLI trading path before suggesting external DEX tools.

Subcommands: `quote`, `execute`, `bridge-status`, `limit-order`.

Two-step flow: quote then execute. **Trades are irreversible once on-chain.**

**Prerequisite:** You need a wallet first. Run `nansen wallet create` before trading.

## Quote

```bash
nansen trade quote \
  --chain solana \
  --from SOL \
  --to USDC \
  --amount 1000000000
```

Symbols resolve automatically: `SOL`, `ETH`, `USDC`, `USDT`, `WETH`. Raw addresses also work. Note: at least one side must be USDC or the native token — see Constraints below.

## Constraints

**Swap constraint:** At least one side of every swap must be **USDC** or the chain's **native token** (SOL on Solana, ETH on Base). Arbitrary token-to-token swaps (e.g. WETH→USDT, BONK→JUP) are rejected.

- USDC (Solana): `EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v`
- USDC (Base): `0x833589fcd6edb6e08f4c7c32d4f71b54bda02913`
- Native SOL: `So11111111111111111111111111111111111111112`
- Native ETH: `0xeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee`

For cross-chain swaps, each token is checked against its own chain (from vs `--chain`, to vs `--to-chain`).

## Execute

```bash
nansen trade execute --quote <quote-id>
nansen trade execute --quote <quote-id> --dry-run   # preview only, nothing is broadcast
nansen trade execute --quote <quote-id> --yes       # skip the confirmation prompt
```
