Tenderly introduces TXN simulations on its blockchain gateway for efficient dApp development

Tenderly, creators of a blockchain development platform, today announced that it is the first web3 development platform to offer simulations through RPC on its Tenderly Web3 Gateway, the company’s production node as a service.

Note, Tenderly already processes more than 50 million simulations per month through its Transaction Simulator. Now, the company is introducing the same capabilities to the world of JSON-RPC.

Just recently, Tenderly entered the node infrastructure space with its Tenderly Web3 Gateway, which is built on top of more than four years of dev tools and observability experience, and Tenderly continues to deliver new products into the node space.

The Tenderly Web3 Gateway is a tightly integrated part of its development platform that helps engineers streamline the process of building and deploying smart contracts. The gateway has support for 20+ EVM-based (Ethereum Virtual Machine) networks, Tenderly provides developers with a variety of options to achieve greater speed, improve scalability, and reduce costs.

Now, with the addition of simulations to Tenderly Web3 Gateway, Tenderly enables developers to build smarter and more efficient decentralized applications (dApps) with more powerful and easy-to-use dApp building blocks. Setting up simulations and sending transactions on-chain is made possible through a single RPC URL and a custom-built RPC method.

The importance of simulating transactions before sending them is reflected in that developers have greater insight into the execution of their transactions, including more visibility into failures and errors, as well as gas consumption issues.

Armed with this essential information, developers can embed transparency and predictability directly into their dApp, increasing transaction visibility and reducing the chances of failures and/or costly mistakes for all of their users. Additionally, beginner developers who are exploring smart contract optimization options can also benefit from Tenderly Web3 Gateway due to its simple and easy-to-use design.

“Our initial launch of Tenderly Web3 Gateway last month was just the tip of the iceberg for what we plan to do in the node provider space. By integrating simulations with Tenderly Web3 Gateway, we set the direction for the evolution of the node provider ecosystem. We already have the next big thing in our sights and under development that will even further simplify web3 developers’ life.”
– Andrej Bencic, CEO & Co-Founder of Tenderly

Key features of the Tenderly Web3 Gateway include:

  • Custom-built RPC endpoint – To run simulations through the gateway, all developers have to do is add a single RPC URL to their code and call a custom-built RPC method. This eliminates the need to integrate separate APIs for simulations and deployment, ensuring a faster development process without configuration pain.
  • Fast response time – The multi-regional architecture of Tenderly Web3 Gateway automatically routes simulation requests to the location nearest to the user, which reduces latency and ensures the simulation results are returned almost instantaneously.
  • Simulate against real mainnet data – When running simulations through Tenderly Web3 Gateway, a transaction is executed against a copy of the most up-to-date Mainnet data, eliminating the guesswork and manual effort that goes into ensuring the success of transactions before they hit the blockchain. Web3 developers can integrate this functionality into their dapps to provide a more transparent and predictable experience for their users.
  • 100% accurate simulation results – Since transactions are simulated against the latest state of the blockchain, developers get accurate insights into what would happen before sending the transaction. The simulation results received back from Tenderly help developers correct errors and understand the outcome of transactions being added to the blockchain.

DFINITY brings new smart contract functionality to Bitcoin with Internet Computer integration

DFINITY Foundation, the not-for-profit organization contributing to the development of the Internet Computer (IC) — a high-speed, internet-scale public blockchain — has announced today the Internet Computer’s mainnet integration with Bitcoin, bringing smart contract functionality to the cryptocurrency.

Now, the Internet Computer can serve as a layer-2 for Bitcoin where smart contracts on the Internet Computer can hold, send and receive bitcoin natively, without the need for bridges or other 3rd-parties. This provides a trustless foundation for varied DeFi and web3 applications seeking to code Bitcoin.

“Blockchains are like walled gardens, incapable of interaction between one another. When this comes to Bitcoin, applications, such as DeFi applications, that could benefit most from interacting with the world’s largest cryptocurrency do not have the ability to do so. The Internet Computer’s integration with Bitcoin is a true game-changer for the industry, finally bringing smart contract functionality to Bitcoin and enabling a whole new landscape of DeFi and dapp development never before possible using BTC.”
– Manu Drijvers, Director of Engineering at the DFINITY Foundation

With IC integration, bitcoin can be used for DeFi activities like yield farming, lending, payments, and more…

This is achieved through the Internet Computer’s enhanced Chain-key cryptography. The direct integration with Bitcoin averts the need for bridged and wrapped Bitcoin, a technique used to facilitate interaction between different blockchains, but one that is error-prone and often hacked.

To enable fast bitcoin transactions between smart contracts on the Internet Computer, the DFINITY Foundation is now working on Chain-Key Bitcoin (ckBTC). Here, ckBTC will act as a local ledger facilitating fast transactions with low fees and only settle transactions on the Bitcoin network when necessary.

Benefits / Developers

The Internet Computer’s integration with Bitcoin also provides a more secure alternative to centralized bridges in the form of threshold ECDSA (Elliptic Curve Digital Signature Algorithm). The implementation of ECDSA empowers the Internet Computer’s canister smart contracts, to directly conduct bitcoin transactions without an intermediary or bridge.

ICP’s developer community has long expressed a strong demand for this feature…

DEX projects such as Helix or IC Lighthouse are already building on the Bitcoin and Chain-Key signing features to offer bridgeless inter-chain token swaps. Moreover, a few ecosystem dApps are also ready to launch some creative use cases beyond DeFi.

Among them is the crowdfunding platform, CrowdfunNFT – which will accept funding for projects in BTC. The aim is to expand the crowdfunding market overall and bring in a fresh set of project backers to crypto. Other examples of use cases in development are transactions in BTC on NFT marketplaces and peer-to-peer transfer of BTC directly on social media and messaging dApps.

Bringing new programmability to Bitcoin will open more unique and imaginative use cases in the future.

Crypto exchange Coinbase to support Easy Bank Transfers for UK users

Coinbase, the popular bitcoin & crypto exchange company, announced today it will be rolling out ‘Easy Bank Transfers’ for UK users. The new feature delivers an easy way to add funds to Coinbase accounts.

Through a partnership with TrueLayer, one of Europe’s leading open banking platforms, Coinbase is able to support Easy Bank Transfers, which relies on open banking technology.

In the weeks ahead, users will be able to link their bank account directly with their Coinbase account, without needing to enter their bank details, for a more convenient and user-friendly experience.

“Coinbase is one of the first major crypto platforms to offer users rapid, secure deposits into their Coinbase account via open banking. Easy Bank Transfers solve these issues for Coinbase users: users no longer have to manually type out payee details, rely on copy/paste, be sent through long verification steps, or anxiously wait for confirmation that a payment was successful.”
– The Coinbase Team

Open banking delivers several other key benefits for Coinbase users, including:

  • Security – No one can access users’ login details or banking passwords through open banking.
  • Ease of Use – Transferring funds via open banking is often faster than making a conventional online transfer, especially on mobile, because of how your bank account is linked to Coinbase.
  • Control – The user has full control over who sees their banking information, and is able to specify exactly what level of access is permitted.
  • Safety – Companies can only take payments with the user’s authorization as the account owner.

Biconomy releases new SDK for better crypto and blockchain development

Biconomy, a web3 development platform & toolkit that superpowers blockchain technology stacks, today announced it has launched a software development kit (SDK) to transform the way developers build easy-to-use decentralized applications (dApps).

Since 2019, Biconomy has been engaged with the web3 infrastructure space by building easy-to-integrate, plug-and-play APIs for developers to scale their projects. The Biconomy SDK introduces time-saving steps for developers such as reducing multi-step transactions into one-click interactions, simple-to-use smart contract wallets, and a conveniently gasless and chainless experience for users.

Easier Development

As institutional and retail adoption of cryptocurrencies and dApps grow, dApp developers can onboard more web2 users by hiding the nuts and bolts behind complex on-chain transactions. This way, the majority of web2 users can onboard and interact with dApps easily — playing games, buying and trading NFTs and other digital assets — without deep knowledge of blockchain technology. dApps can save their users a ton of time and costs.

“There is no point building in web3 if no one can use your products. User onboarding and retention are key for the growth of individual dApps and the crypto environment as a whole. Biconomy was built with the next billion web3 users in mind and we are fulfilling this goal by meeting developer and user needs. From gasless to one-click transactions, we are making sure engaging with web3 feels second nature and as easy as signing your name.”
– Ahmed Al-Balaghi, Co-Founder of Biconomy

The introduction of the Biconomy SDK opens up further opportunities. Developers can offer users practical UX benefits such as secure web2-like social logins and recovery for accounts.

One-click interactions for multistep transactions. Transaction batching removes the need for repeated authorization. Gasless and chainless experiences. Convenient fee payments in ERC20 tokens and fiat on-ramps and credit card purchases of crypto or NFTs.

Features

Biconomy SDK brings blockchain-agnostic, web2-like experiences to your dApp in a non-custodial manner.

Here’s what is possible with the SDK today:

  • Easy User Onboarding – Social login, account creation & recovery to seamlessly onboard web2 users.
  • Fiat On Ramp – Let end-users easily & reliably buy/sell crypto within a dApp.
  • Gasless Transactions – dApps can sponsor gas fees to make user interactions as simple as web2 transactions.
  • Paying Gas Fees In ERC20 Tokens –  Users can utilize any ERC20 asset in their wallet to pay gas fees.
  • Custom Transaction Bundling – Allow developers to build methods to do transaction batching which enables users to execute multiple actions, even across multiple chains, in a single transaction (e.g. approve & deposit can be done in one transaction without changing anything in dApp smart contracts).
  • Cross-Chain Contract Calls & Asset Transfer – Coming soon, the Biconomy SDK will provide in-dApp cross-chain asset bridging and contract calls to enable a chainless experience for end-users.

With its current API suite, Biconomy enables more than 50,000 transactions daily, with users’ gas fees sponsored by the dApps. It also allows users to pay fees in a token other than that of the blockchain.

This has already resulted in onboarding more than 2.8 million web3 users, more than 25 million transactions across 8 EVM chains, and integration with 200+ dApps including dYdX, Perpetual Finance, Aavegotchi, Decentraland, Sandbox, Animoca Brands, and Zedrun.
