Newton mainnet beta is now live. Newton enforces rules onchain, starting with DeFi vaults.

Institutional capital has moved onchain faster than the controls meant to govern it. Curated DeFi vault TVL has grown more than 350% in the past year. The capital is here. The enforcement layer is not.

Newton is the authorization layer for the onchain economy. It sits between the moment a transaction is initiated and the moment it settles, and checks the transaction’s rules and safeguards before value moves. A curator defines what is permitted, in advance. Newton enforces it. Today, alongside Newton Foundation's announcement of Newton mainnet beta, Magic Labs is launching VaultKit the SDK curators use to make a vault's rules enforceable onchain.

The problem: rules that aren't enforced

Blockchains are strong settlement infrastructure, but they still lack the authorization layer institutions need. Today, critical controls around asset movement, compliance, and risk are managed offchain across fragmented systems and workflows, making them harder to verify, govern, and trust at scale.

How Newton works

Newton adds one step to the transaction lifecycle: a policy check, enforced before settlement. Before a transaction clears, the Newton network of operators evaluates the policies that apply and issues a cryptographic proof, an attestation, that authorizes the transaction to proceed or be blocked. The curator writes the rules; Newton enforces them and writes a signed receipt onchain, legible to an allocator or a regulator, verifiably and without revealing the underlying data. 

"Magic made crypto simple to enter - onboarded 57 million wallets with a login that felt like any web2 app," said Sean Li, Co-founder of Magic Labs. "Our next mission is to make it safe to stay. In March, alerts fired across the industry while allocation bots kept feeding a collapsing market. The bots weren't broken; they did exactly what they were told. Newton enforces a vault's mandate onchain before each transaction settles, across compliance, identity, security, and risk, whether the manager is a human, a bot, or an AI agent, and leaves a signed record the curator can hand to an allocator or a regulator. Every other product in this market tells you what happened. Newton lets you decide what happens, and what doesn't."

VaultKit

Created by Magic Labs, VaultKit is the SDK curators use to make a vault's rules enforceable onchain, with no authorization logic to build from scratch. Curators now have access to best-in-class compliance, security, and risk enforcement through the VaultKit ready to use with Euler and live on Base and Ethereum, with more chain support coming soon.

Policy is separate from code: a new sanction or a revised threshold takes effect immediately, with no contract to rewrite or redeploy.

The Vault Protection Kit launches alongside the Newton network's mainnet beta, with policy guidelines for OFAC sanctions compliance and an integration with Chainalysis Hexagate for smart contract risk monitoring.; vaults.fyi for live vault health and ratings; RedStone for price feeds and Credora for risk ratings and collateral intelligence; and Webacy provides real-time on-chain risk intelligence. The Newton protocol also leverages technology from Eigen Labs and Succinct's ZK technology to help secure the protocol, Rhinestone for secure smart account infrastructure, and Octane for continuous, AI-powered smart contract security.

Integration with vaults is seamless via hook, gate, or a provided smart account, and reference implementations for additional popular vault platforms are forthcoming. Learn more in docs.

"A policy is only as strong as the data behind it," said Mike Massari, Head of Partnerships at RedStone. "Credora and RedStone bring price data, risk ratings, and collateral intelligence into Newton's policies, so curators can enforce risk with the same confidence they track market prices."

Beyond vaults

Vaults are the starting point for Newton, not the ceiling. The same authorization layer will extend to RWAs, stablecoins, and agentic commerce, with policies discoverable and reusable through an Internet of Policies marketplace.

Newton is stewarded by the Magic Newton Foundation. Its core developer is Magic Labs, the embedded-wallet infrastructure behind Polymarket, supporting 57M+ wallets and 200,000+ developers, and backed by lead investor PayPal Ventures.

Getting started

Newton mainnet beta is live today. If you operate a vault, allocate to one, or own the controls around institutional capital onchain, request a demo to see Newton enforce policy on a live transaction. Build with VaultKit in the developer docs, or explore records on Newton Explorer.
