Arc support is live with Turnkey from Day 1

Turnkey is proud to announce Day 1 support for Arc, the Economic OS for the internet.

Now live, Arc mainnet brings real-time money movement, agentic economic activity, and global financial markets to an EVM-compatible L1. It launches with USDC as gas, deterministic sub-second finality, predictable dollar-based fees, and live markets spanning lending, trading, onchain FX, payments, and tokenized assets.

Arc builders have access to Turnkey’s complete wallet infrastructure today, with everything they need to ship payment flows, agentic commerce, and treasury applications directly on Arc mainnet.

What Turnkey supports on Arc

Turnkey gives Arc builders production-ready infrastructure for embedded wallets, transaction management, and policy enforcement:

• Secure, non-custodial wallets for every user. Embed wallets directly into your Arc application with no backend required. Users can authenticate with email, SMS, passkeys, social logins, or an existing Ethereum or Solana wallet. Private keys remain protected inside secure enclaves and are never exposed to Turnkey, your application, or your team.
• Complete transaction management, out of the box. Turnkey manages the full transaction lifecycle on Arc, including construction, signing, nonce management, broadcast, and monitoring. Parse transaction details and enforce custom policies before every signature without building additional infrastructure.
• Gas sponsorship for frictionless transactions. Cover fees directly and set organization-wide, USD-denominated spending limits without managing a relayer or gas tank contract. Users can move money and execute trades without acquiring gas first.
• Real-time balances across every wallet. Access Arc wallet balances programmatically, with webhooks for confirmed and finalized balance and transaction updates. Use them to power payment, treasury, and monitoring flows.
• In-app swaps. Connect users to liquidity and cross-chain routing through Turnkey’s supported swap integrations. Users can swap and move assets inside your product without you building or maintaining the routing logic.

Why Turnkey’s policy-controlled signing on Arc matters

Arc brings financial primitives onchain, but signing risk still needs to be managed.

A wallet might be asked to approve a token transfer or sign a transaction that looks simple at the interface level but carries complex execution details underneath. Without visibility into what's actually being signed, users and developers have no way to enforce boundaries.

Turnkey's policy engine helps teams inspect those transactions before they're signed. Policies can define what a wallet is allowed to do, where it can send funds, which contracts it can interact with, and what actions require approval. The result is a safer signing layer for financial applications building on Arc.

Policies are enforced inside the same secure enclaves that protect private keys. Every signing action can be inspected, scoped, controlled, and logged, giving Arc builders a secure foundation for moving money and executing financial transactions at scale.
