The Blend SDKs are published as three packages:

Core SDK

Low-level, type-safe client for Blend API with Decimal.js precision and robust error handling.

Actions SDK

High-level deposit/withdraw/rebalance workflows built atop the core client, with cross‑chain routing.

Types

Shared domain and core TypeScript types used across the SDKs and apps.

Cross‑chain

Built‑in routes via LiFi (EVM) and Garden (Botanix/native BTC) with ActionPlan outputs.

GitHub Monorepo

Source code, issues, and package directories for @blend-money/sdk-core, @blend-money/sdk-actions, and @blend-money/sdk-types.

​
Packages

  • @blend-money/sdk-core – Core HTTP client, modules (safe, strategy), Decimal.js utilities, cross‑chain adapters
  • @blend-money/sdk-actions – High‑level actions (deposit, withdraw, rebalance) with LiFi and Garden routing
  • @blend-money/sdk-types – Centralized, strict TypeScript types (no runtime)

​
Install

  • pnpm
  • npm
  • yarn
pnpm add @blend-money/sdk-core @blend-money/sdk-actions

​
Quick example

import { BlendClient } from "@blend-money/sdk-core";
import { BlendClientWithActions } from "@blend-money/sdk-actions";

const client = new BlendClientWithActions({
  baseUrl: "https://api.blend.money",
  userAddress: "0x1234567890abcdef1234567890abcdef12345678",
  integratorId: "example-app",
}, {});

const safe = await client.safe.getSafeAddress(8453);
const strategies = await client.strategy.getAvailableStrategies();
const plan = await client.actions.deposit(
  { address: "0x...", symbol: "USDC", decimals: 6, chainId: 8453 },
  strategies[0],
  1_000_000n,
  50,
);
All arithmetic should be modeled with Decimal.js at the edge; see package READMEs for examples and testing guidance.
