🏆 Just won 1st Place at the @MetaMaskDev x @monad hackathon! Built @ZeroClickApp - DeFi's first "Smart Card" that lets you trade with ZERO wallet signatures. Here's how ZeroClick is fixing the UX problem that keeps 99% of people away from DeFi 🧵👇

To learn more, explore the full architecture guide:

Until then, try the Embedded Wallets Node.js SDK: ☑️Direct signer access ☑️ Non-custodial by default ☑️No manual key management ☑️Policy-controlled backend logic 🔗

We are working on a one-click server wallet experience, production-ready, with attestation, policy, and ERC-8004 interoperability built in. Stay tuned for early access 👀

With ERC-8004, every AI agent needs a signing identity it can prove onchain. Server wallets make this practical, pairing a secure backend signer with verifiable agent identity.

Why not MPC? While our TSS MPC SDKs are great for decentralization, multi-party signing adds latency. For AI use cases, speed + safety policies matter most. Hence, a single-key TEE design wins.

While we explored multiple architectures, the ideal setup uses a Trusted Execution Environment (TEE) like AWS Nitro Enclaves: ☑️Keys generated + stored securely inside the enclave ☑️No external network access ☑️Enforced limits (spend, scope, frequency) ☑️Optional human approval

A server wallet manages private keys on behalf of an AI agent or app. The agent authenticates requests -> the backend signs transactions -> no key exposure. It’s fast, secure, and policy-controlled.

AI agents are coming onchain. 🤖 With ERC-8004 standardizing how agents are discovered, we need a way for them to safely sign and act across networks. That’s where Server Wallets come in: a secure signing backend for AI. Here’s how to build the ideal setup 👇

The @MetaMaskDev Smart Accounts Hackathon w/ @monad & @envio_indexer is wrapped! $5K. Two weeks. Objective: build next-gen Web3 experiences, focused on account abstraction and smarter UX. Here are the winners. 👇

Introducing Linea Exponent. A three month growth program designed to reward the apps that scale the fastest and bring the most users to Linea. No judges. No pitch decks. No panel votes. Just deploy, scale, and compete.

The results of Mission 8 are out.
