Fireblocks XRP SDK

A stateless SDK and REST API server for Fireblocks customers, simplifying advanced operations on the Ripple Ledger (XRPL).

⚡ Project Overview

Fireblocks XRP SDK enables secure, advanced XRP ledger operations via simple SDK calls or a stateless REST API.
Built for Fireblocks customers who want seamless DEX, token, and issuer operations on Ripple.

Disclaimer
This SDK relies on Fireblocks' RAW signing capabilities. Customers are fully responsible for safe usage, setup, and transaction outcomes. Fireblocks is not liable for any loss of funds resulting from the use of this code. Contact the Fireblocks Professional Services team for assistance.

Prerequisites

Fireblocks workspace and API credentials (how to create an API key).
RAW signing is enabled on your Fireblocks workspace. (Contact your Customer Success Manager for more information)
TAP rules set to allow RAW transactions.
Node.js v18+ for SDK usage.
Docker (for REST API server).

🚀 Features

Advanced XRPL support: DEX (OfferCreate/Cancel, CrossCurrencyPayment), token & XRP transfers, setting trust lines, account settings, clawback, freeze/unfreeze and burn.
Fireblocks wallet integration: Secure MPC key management, raw signing flows, and transaction creation.
Raw content validation with callback handler support Any Raw transaction created by the SDK includes the unhashed payload for further validation actions on your callback handler before signing.
Stateless, pool-managed SDK: Efficient use of Fireblocks APIs with per-vault pooling.
REST API: Simple to run as a Docker container.

📦 Installation

SDK / Library Usage

Clone this repository and install dependencies:

git clone https://github.com/fireblocks/fireblocks-xrp-sdk.git
cd fireblocks-xrp-sdk
npm install

REST API (Docker)

Build and run the REST API server:

cp .env.example .env
# Edit .env to your configuration
docker-compose up --build

By default, the API server runs on port 3000.
To change the port, set the PORT variable in your .env file.

The project includes a sample docker-compose.yml and .env.example for quick setup.

⚙️ Configuration

All configuration is via environment variables.

Start by copying .env.example to .env and editing for your environment:

cp .env.example .env

Variable Name	Required	Default	Purpose
`FIREBLOCKS_API_KEY`	Yes	–	Your Fireblocks API key UUID
`FIREBLOCKS_API_SECRET`	Yes	–	Path to Fireblocks private key
`FIREBLOCKS_VAULT_ACCOUNT_ID`	No	–	Optional - Can be added to use a single wallet SDK intance, should be ommited when used as a dockerized server.
`FIREBLOCKS_ASSET_ID`	No	XRP_TEST	Use `XRP` for mainnet, `XRP_TEST` for testnet
`FIREBLOCKS_BASE_PATH`	No	US	Fireblocks API environment (see docs for region URLs)
`SDK_LOG_LEVEL`	No	info	Log level: debug, info, warn, error, fatal
`PORT`	No	3000	API server port (REST mode)

🔑 Mounting Your Fireblocks Private Key in Docker

The SDK and REST API require access to your Fireblocks API private key (FIREBLOCKS_API_SECRET) for signing and secure communication with Fireblocks. When running inside Docker, you must mount this file and reference it correctly.

Store Your Private Key Place your Fireblocks API private key file in the project directory under ./secrets/fireblocks_secret.key:

your-project-root/
│
├─ secrets/
│ └─ fireblocks_secret.key
├─ .env
├─ docker-compose.yml
└─ ...

Important: Never commit your private key to source control.

Reference the Private Key in .env Set the environment variable in your .env file to match the path inside the container:

FIREBLOCKS_API_SECRET=/secrets/fireblocks_secret.key

How Docker Compose Mounts the Key Your docker-compose.yml already mounts both the secrets folder and the .env file into the container:

services:
  fireblocks-xrp-sdk:
    build:
      context: .
      dockerfile: Dockerfile
    volumes:
      - ./secrets/fireblocks_secret.key:/secrets/fireblocks_secret.key:ro
      - ./.env:/app/.env:ro
    ports:
      - "3000:3000"
    env_file: ./.env
    environment:
      - FIREBLOCKS_API_SECRET=/secrets/fireblocks_secret.key
    restart: unless-stopped

This setup ensures that:

Your private key is available in the container at /secrets/fireblocks_secret.key.

The .env file with your Fireblocks credentials is available at /app/.env.

The FIREBLOCKS_API_SECRET environment variable tells the SDK where to find the key.

Running the API Server Build and run the container with:

docker-compose up --build

Security Notes Do not include your private key in the repo. Only give read permissions (:ro) to the mounted secret. Consider using secrets management solutions for production deployments.

🛠️ Usage

SDK Usage Example

Sample usage via direct SDK in Node.js (see /examples for more):

import { FbksXrpApiService } from "./src/api/ApiService";
import { TransactionType } from "./src/pool/types";
import { BasePath } from "@fireblocks/ts-sdk";
import dotenv from "dotenv";

dotenv.config();

(async () => {
  const apiService = new FbksXrpApiService({
    apiKey: process.env.FIREBLOCKS_API_KEY || "",
    apiSecret: process.env.FIREBLOCKS_API_SECRET || "",
    assetId: process.env.FIREBLOCKS_ASSET_ID || "XRP_TEST",
    basePath: (process.env.FIREBLOCKS_BASE_PATH as BasePath) || BasePath.US,
  });

  const params = {
    sellAmount: "10",
    buyAmount: {
      currency: "THT",
      issuer: "rpbkpPF8PrPuMN8NgEVkCsJDCWwP9KePFq",
      value: "2",
    },
    flags: {
      tfPassiveOffer: true,
      tfSellOffer: true,
    },
  };

  const opts: ExecuteTransactionOpts = {
    vaultAccountId: process.env.FIREBLOCKS_VAULT_ACCOUNT_ID || "",
    transactionType: TransactionType.OFFER_CREATE,
    params,
  };

  const res = await apiService.executeTransaction(opts);

  if ("result" in res) {
    console.log(`Tx submitted: ${res.result.hash}`);
  } else {
    console.log(`Transaction submitted with ID: ${res.id}`);
  }

  await apiService.shutdown();
})();

See more SDK samples in /examples/.

Raw content validation support

Any transaction created by the SDK (excluding xrpTransfer() that does not rely on Raw signing) includes the unhased transaction payload as an additional extraParameters key (unhashedTxPayload), this is passed to allow pre-signature validation by a callback handler instance connected to your Fireblocks API Co-Signer instance.

In the transaction object received by the callback handler, the extraParameters object will have this structure:

{
  "rawMessageData": {
    "messages": [
      {
        "content": "4147FCCCB874E67DDB05C3D353972EFA21DC0D18F6F0B3768C22AFDAAEEC10E7"
      }
    ]
  },
  "unhashedTxPayload": {
    "Fee": "10",
    "Amount": {
      "value": "100",
      "issuer": "rhsMZjNb4ehEHdfLbMCRBnwMr7XAnicnVS",
      "currency": "FBX"
    },
    "Account": "rpbkpPF8PrPuMN8NgEVkCsJDCWwP9KePFq",
    "Sequence": 7855319,
    "Destination": "rfSeUdwJC4ejRZ3mNfdH7KMWPyGGx6UTmf",
    "SigningPubKey": "03077CBD3FC5F7B9FC8364C83900A78659AF60D16C62DB2860C498C3593D29BA2D",
    "TransactionType": "Payment",
    "LastLedgerSequence": 8224033
  }
}

Use the unhashedTxPayload parameter to validate the raw message (content) before signing it.

REST API Usage

1. Run API Server

docker-compose up --build

2. API Authentication

All requests require valid Fireblocks API credentials via environment parameters. No additional API key/JWT is needed on REST endpoints.

3. Try Endpoints (cURL)

OfferCreate example:

curl -X POST http://localhost:3000/api/dex/offerCreate/<vaultAccountId> \
  -H "Content-Type: application/json" \
  -d '{
    "sellAmount": "10",
    "buyAmount": {
      "currency": "THT",
      "issuer": "rpbkpPF8PrPuMN8NgEVkCsJDCWwP9KePFq",
      "value": "2"
    },
    "flags": {
      "tfPassiveOffer": true,
      "tfSellOffer": true
    }
  }'

4. Postman Collection

Import Fireblocks-XRP-SDK-API.postman_collection.json All REST API routes and sample payloads are included for testing.

📚 API & Documentation Endpoints

The running API server exposes interactive documentation and SDK reference for easier integration and onboarding:

Purpose	URL	Description
Swagger UI	`http://localhost:3000/api-docs`	Interactive REST API explorer for all endpoints.
TypeDoc Reference	`http://localhost:3000/type-docs`	SDK Classes/Methods documentation (generated by TypeDoc).

Both URLs assume the default port 3000—change if you modify your server port. The TypeDoc reference is also available here.

DEX Routes:

POST /api/dex/offerCreate/:vaultAccountId
POST /api/dex/offerCancel/:vaultAccountId
POST /api/dex/crossCurrencyPayment/:vaultAccountId

Token Routes:

POST /api/token/tokenTransfer/:vaultAccountId
POST /api/token/accountSet/:vaultAccountId
POST /api/token/burnToken/:vaultAccountId
POST /api/token/clawback/:vaultAccountId
POST /api/token/freezeToken/:vaultAccountId
POST /api/token/trustSet/:vaultAccountId
POST /api/token/xrpTransfer/:vaultAccountId

Each endpoint expects a JSON body and returns a transaction result. See Postman or /examples/ for detailed payloads.

Error Handling

All errors return a JSON.

Bad request example (400):

{
  "error": "Missing vault account ID",
  "message": "Vault account Id is missing from the request URL"
}

Not found example (404):

{
  "error": "Not Found",
  "message": "Cannot POST /api/dex/offerCanc"
}

🧪 Development & Contribution

Run tests:
```
npm run test
```
CI/CD: The project uses GitHub Actions for lint, build, and tests.
Contributions: PRs and issues are welcome!

🛡️ Security & Responsibility
