Alkahest Developer Skill

When to Use

Use this skill when a developer wants to write code that interacts with Alkahest escrow contracts. This covers:

• Integrating Alkahest into an application
• Writing bots/agents that create escrows, fulfill obligations, or arbitrate
• Building custom arbiters or obligation contracts
• Understanding SDK patterns and APIs

SDK Overview

SDK	Language	Package	Foundation
TypeScript	TypeScript/JavaScript	@alkahest/ts-sdk	viem
Rust	Rust	alkahest-rs	alloy
Python	Python	alkahest-py	PyO3 wrapper around Rust SDK

Client Setup

TypeScript

import { createWalletClient, http } from "viem";
import { privateKeyToAccount } from "viem/accounts";
import { baseSepolia } from "viem/chains";
import { makeClient } from "@alkahest/ts-sdk";

const walletClient = createWalletClient({
  account: privateKeyToAccount("0xPRIVATE_KEY"),
  chain: baseSepolia,
  transport: http("https://rpc-url"),
});

// Full client with all extensions
const client = makeClient(walletClient);

// Custom addresses (optional)
const client = makeClient(walletClient, customAddresses);

// Minimal client for custom extension patterns
const minimal = makeMinimalClient(walletClient);
const extended = minimal.extend((base) => ({
  custom: makeErc20Client(base.viemClient, pickErc20Addresses(base.contractAddresses)),
}));

Rust

use alkahest_rs::AlkahestClient;

// Full client with all extensions (Base Sepolia default)
let client = AlkahestClient::with_base_extensions(
    "0xPRIVATE_KEY",
    "https://rpc-url",
    None, // uses Base Sepolia addresses
).await?;

// Custom addresses
use alkahest_rs::{DefaultExtensionConfig, ETHEREUM_SEPOLIA_ADDRESSES};
let client = AlkahestClient::with_base_extensions(
    "0xPRIVATE_KEY",
    "https://rpc-url",
    Some(ETHEREUM_SEPOLIA_ADDRESSES),
).await?;
