Alchemy

Alchemy is a web3 infrastructure platform that gives developers reliable node RPC access, data APIs, and smart wallet tooling for building blockchain applications. It supports Ethereum and 50+ other networks including Polygon, Arbitrum, Optimism, Base, and Solana, and is used by companies like Visa, Circle, Stripe, and OpenSea.

Tenderly

Tenderly is a blockchain operations platform focused on letting teams simulate, validate, and monitor onchain actions before real capital or users are exposed. Its Simulator previews transaction outcomes against live production blockchain state, with controls to override prices, state, and time, so teams can catch problems before a transaction is ever broadcast. Beyond simulation, Tenderly's Console gives decoded, multichain transaction visibility for debugging, its Monitor product delivers real-time alerting with fast detection-to-response times for critical onchain conditions, and its Node product provides low-latency RPC infrastructure across more than 100 networks. DeFi protocols such as Aave, Uniswap, Safe, and Morpho use the platform for engineering, finance, and risk workflows.

Infura

Infura is a Web3 development platform, now part of MetaMask Developer, that gives developers reliable API access to major blockchain networks without running their own nodes. It provides high-availability RPC endpoints used to build and scale decentralized applications.

Fewsats

Fewsats is a payments infrastructure platform built for the emerging AI economy. It gives AI agents, assistants, copilots, and autonomous services the ability to request and complete payments without ever being given direct access to financial credentials or payment method details. Instead of handing sensitive financial data to an AI, Fewsats acts as a controlled intermediary that keeps the human user in charge of every meaningful transaction. For clients, the platform provides a developer-friendly SDK that lets AI tools handle HTTP 402 Payment Required responses automatically, so agents can buy API access, data, or other services without forcing the user to switch to a browser or go through a complex setup. Administrators can set budgets, transaction limits, and approval workflows, and every payment request can be routed through a human-in-the-loop review when needed. For service providers, Fewsats unlocks a new revenue channel by making it easy to create paywalled offers and accept micropayments from AI agents with minimal overhead. The platform is designed as a single integration that supports traditional and next-generation payment networks: low-fee ACH and wire bank transfers, universally accepted credit cards, and cryptocurrency stablecoins for global, borderless transactions. Fewsats is aimed primarily at developers building AI-facing products, API services, and agent networks that need a secure, controllable, and frictionless way to move money between software entities and their human owners.
