This newsletter is made possible thanks to Tenderly’s Web3 Gateway!
The Tenderly platform enables Web3 developers to build, test, monitor, and operate smart contracts in one place. To cover each aspect of the dapp development lifecycle, Tenderly expanded its product offering and released Tenderly Web3 Gateway. This is a production node as a service that delivers fast and easy access to the blockchain.
Tenderly Web3 Gateway is fully integrated with the rest of the platform, combining infrastructure with development tooling and observability. It enables blockchain developers to:
- Speed up read-heavy workloads up to eight times
- Set up reliable node infrastructure with 100% blockchain data consistency
- Reduce node infrastructure management overhead
- Scale dapps with ease to meet their growing user base
- Unify dapp development by combining infrastructure with tooling and observability
- Improve development teams’ velocity and collaboration by eliminating development silos
- Preview transaction outcomes directly from Tenderly Web3 Gateway before sending them on-chain
