New updates and product improvements

  • Improved the perfomance of our network of RPCs. Incorporated circuit breaker and load balancer that helped us decrease redundancy issues and throughput across the transaction cloud.
  • We've added orderbook support to instantly list any asset across Seaport protocol based marketplaces. Starting with Beam subnet support with more coming soon
  • Added support for loading the library as a JS script
  • 74% size reduction for openfort-js SDK
  • Token Swap Module added support for Degen chainx
  • Pre-generate embedded wallets associated with a given account, like an email address, without requiring the user to login, all from the backend.

Updated NodeJS and C# SDKs available.

  • We've deployed the improvement around webhooks. You can now subscribe to receive webhook notifications on successful, failed, cancelled and broadcasted transactions.

  • Improved iframe communication and new endpoints to sign types of transaction from Shield.

Announcing two new endpointto exhange tokens:

  • /v1/exchange endpoint, designed to facilitate faster and more efficient token swaps on our decentralized exchange (DEX). This feature allows you to initiate token swaps directly, ensuring that your transactions are executed with optimal speed and precision.
  • /v1/exchange/quote endpoint, which provides real-time quotations for token swaps. This allows developers to fetch potential swap details, including fees and slippage, before executing the transaction.

Check the exchange endpoint in the API reference docs.

Also, we're happy to share that Openfort is now Paymaster agnostic. This means you can define custom logic to select the paymaster (if any) to use with the accounts you control. This allows you to use your own paymaster or even use multiple paymasters in different scenarios.


Creating self-custodial signers are one of the key milestones for any web3 applications onbaording users in their platform. Shield brings a powerful new way to manage the recovery shard.

This highly requested feature allows the most advance games to self-host the Shield server themselves in order to add further resilinece in their system.

Use Shield to:


Openfort Smart Embeded Wallet is built on a novel combined architecture of smart wallet technology and a secure enclave signing service.

By design our solution is fully equipped with:

  • OpenID Connect and OAuth2 support, designed in a non-custodial framework, making it simple to connect any OAuth2 provider for seamless wallet access.
  • Custom auth support, so you can use your preferred auth and gaming baxkend solution.
  • Built with verifiable and opensource server called Shield.
  • Ability to self-host the Shield and the iframe.

→ Try on Unity. → Try on browser.

You can now integrate in-app purchases safeliy in your web3 game and start monetizing players regularly (all within the compliance boundaries o Apple and Google).

Here is how we're using in-app purchases in our sample:

  • Buy soft-currencies (not crypto).
  • Buy NFTs directly with IAP or your soft-currency.
  • Sell NFTs for your game token (hard currency).

Read more about IAP in web3.

After deploying one of the first versions of smart accounts compliant with the ERC4337. We've finally pushed the envolope in auditing it with CertiK. Both the Smart Contract Wallets as well as the Paymasters were part of the scope.

We take security of our contracts very seriously and we constantly thinking ways to better explain the thread model and security decision we take internally. To read more about the security at OPenfort you can find go to the Security page.

You can read teh audit here and here is the public profile.


Use internal wallets (dev accounts) as you develop your game in order to scale and customize any onchain interaction between the players and your wallets. This lets you create an optimize onchain transactions in order to move your games economy onchain.

  • You can send NFTs to users purchasing an asset instead of minting directly from the smart contract.
  • You can airdrop users some in-game tokens from an existing dev accounts.
  • Use it as an escrow account so that you can withold user's assets until the outcome is decided.

Above and beyond

Dev accounts can be configured to either use relayers in order to execute transactions or simply with the wallets native network token. his feature allows your app to sponsor gas for your users to transfer NFTs, list items on marketplaces, and more.

Transaction Cloud

Nov 24, 2023

Today's fragmented solutions and their gaps—in the areas of throughput, nonce management, reorg detection, transaction retries, and more—force developers to DIY their own transaction, wallet, key, and gas management infrastructure.

Our Transaction Cloud addresses all of the challenges above and more. It abstracts the complexities of writing to blockchains through simple HTTP REST APIs—enabling developers to manage the entire transaction lifecycle with unprecedented ease and scale.

- High-Performance REST APIs: Achieve thousands of requests per second with simple HTTP APIs that eliminate the need for private keys, wallets, or gas management. Integrate transactions effortlessly with one line of code, ensuring scalability and reliability.

- Nonce Management and Idempotency: Automatically ensure transactions are unique and executed in order, preventing double spends and saving engineering time.

- Dropped/Reorg Detection and Auto-Resubmission: Our system automatically retries transactions in case of failures, reducing the need for manual monitoring and enhancing product reliability.

- Horizontally-Scalable Transaction Wallets: Utilize auto-scaling wallets for fast, consistent performance under any load, supporting your growth without architectural changes.

- Auto-Managed Gas with USD Billing: We handle all aspects of gas management, including fluctuations and accounting, allowing you to focus on core operations.

- Real-Time Transaction Lifecycle Management: Get instant updates on transaction statuses from initiation to confirmation, with alerts for any anomalies.

Cross-Chain Signing and Attestations: Facilitate secure interactions across different blockchains with EIP-712 signing and signature-based updates and attestations, reducing complexity and enhancing security.

Gas policies allow you to customize the user experience in your application. The combination of gas policies and rules lets you set control on transactions you want to sponsor and transactions you want the user to charge with.

You can now select three policy strategies:

  • Sponsor transactions by paying the gas on behalf of the user.
  • Let users pay with the in-game token (ERC20) with a dynamic rate (live quote of the token).
  • Let users pay with the in-game token (ERC20) with a fixed rate.

And define 3 policy rules:

  • Sponsor interactions with smart contracts.
  • Sponsor interactions with the smart account.
  • Limit the amount of gas or number of transactions over an interval.

Above and beyond

  • When using the Openfort policies, you will now receive email alerts automatically when you are close to hitting your sponsorship limits. Never see unexpected failed sponsorship again.
  • You can now buy gas credits directly in your dashboard to increase your sponsorship limits in seconds with a credit card - no need to manage native tokens and no limits on sponsorship!

Cherry on top - we're now offering unlimited free gas sponsorship on testnets!
