Dexterity SDK

A TypeScript SDK and CLI for interacting with the Dexterity AMM protocol on Stacks. Dexterity uses an isolated vault system where each liquidity pool exists as an independent smart contract for enhanced security.

Quick Start

npm install dexterity-sdk

import { Dexterity } from "dexterity-sdk";

// Get a quote for swapping tokens
const quote = await Dexterity.getQuote(
  "SP123.token-a",  // token in
  "SP456.token-b",  // token out
  1000000          // amount (in smallest units)
);

// Execute the swap (client mode)
await Dexterity.executeSwap(
  "SP123.token-a", 
  "SP456.token-b", 
  1000000
);

Core Concepts

Environment Setup

Create a .env file in your project root:

# .env
STACKS_API_KEY="your-api-key"  # Required for higher rate limits
SEED_PHRASE="..."              # Optional: Only for server environments

Configuration

The SDK supports both client-side (browser) and server-side usage:

// Client-side (browser)
Dexterity.configure({
  mode: "client",
  network: 'testnet',
});

// Server-side
Dexterity.configure({
  mode: "server",
  network: 'mainnet,
  apiKey: process.env.HIRO_API_KEY,
});

Any configuration can be modified:

// Update individual settings
Dexterity.configure({ maxHops: 3 });
Dexterity.configure({ defaultSlippage: 0.5 });

// Get current config
const config = Dexterity.config

Working with Quotes

Get quotes for potential trades:

// Simple quote
const quote = await Dexterity.getQuote(
  tokenInContract,
  tokenOutContract,
  amount
);

console.log({
  amountIn: quote.amountIn,
  amountOut: quote.amountOut,
  expectedPrice: quote.expectedPrice,
  minimumReceived: quote.minimumReceived,
  fee: quote.fee
});

// Execute the quoted trade
await Dexterity.executeSwap(
  tokenInContract, 
  tokenOutContract, 
  amount,
  { fee: 10000 } // optional parameters
);

Pool Operations

Interact with individual liquidity pools:

// Get a specific pool
const vault = Dexterity.build("SP123.pool-abc");

// Get pool information
const [tokenA, tokenB] = vault.getTokens();
const [reserveA, reserveB] = vault.getReserves();

// Get a quote from the pool
const quote = await vault.quote(
  1000000,
  Opcode.swapExactAForB()
);

CLI Usage

The SDK includes a powerful CLI for interacting with the protocol:

# Install globally
npm install -g dexterity-sdk

# Get a quote
dexterity quote .stx SP2ZNGJ85ENDY6QRHQ5P2D4FXKGZWCKTB2T0Z55KS.charisma-token 1000000

# List all pools
dexterity vaults

# Show debug information
dexterity -d inspect -g

CLI Configuration

Manage CLI settings:

# View config
dexterity config ls

# Set values
dexterity config set maxHops 3 # router graph search depth
dexterity config set defaultSlippage 0.02 # 2% slippage

# Reset to defaults
dexterity config reset

Inspection Commands

Analyze protocol components:

# Inspect a pool
dexterity inspect -v SP2ZNGJ85ENDY6QRHQ5P2D4FXKGZWCKTB2T0Z55KS.charisma-token

# Analyze token routes
dexterity inspect -r .stx SP2ZNGJ85ENDY6QRHQ5P2D4FXKGZWCKTB2T0Z55KS.charisma-token

# Show routing statistics
dexterity inspect -g
