On June 15th, we’re bringing builders, founders & operators together for a special night with @MetaMaskDev in Mexico City 🇲🇽

Huge thanks to all the partners supporting the event and helping strengthen the local ecosystem.

MetaMask Embedded Wallets v11 is live. 🦊

The wallet infrastructure behind McDonald's, eBay, and NBCUniversal — now fully inside the MetaMask developer ecosystem.

If you know @Web3Auth, you already know this product. It just got a major upgrade.

Token-gated features without a separate auth system.

MetaMask Embedded Wallets v11 ships RBAC out of the box — gate by email, wallet address, domain, or token holdings.

Closed betas, loyalty programs, allowlists. All from the dashboard.

[Clawnch 🪽 @Clawnch_Bot]

We have applied to the @MetaMask @1shotapi @AskVenice Smart Accounts Kit Cook-Off with Clawmes 🪽

Clawmes turns any Hermes Agent (@NousResearch) into a full on-chain operator you drive in plain English. Tell it what you want — "watch the six wallets I follow on @Base, and if any buys over $50k of a token with $100k+ liquidity, snipe 0.15 ETH with MEV protection, set a +100% take-profit and a -30% stop" — and it parses that into a concrete, running rule. Natural language is the interface; there are no forms, scripts, or dashboards to wire up.

It's built for conditional and multi-step operations, not one-shot trades: threshold-gated rebalances ("rebalance to 50/30/20, but only if a leg drifts more than 5%"), two-sided price ladders ("if ETH breaks $4,000 sell 25% of my stETH; under $3,000 buy it back"), filtered copy-trading, and full bridge → swap → LP flows — each compiled into triggers, brackets, and schedules that run on their own and report back.

Safety is cryptographically enforced, not just promised. Rather than handing over keys, you grant the agent scoped, revocable on-chain permissions through MetaMask Smart Accounts — ERC-7715 permission grants and ERC-7710 delegation with caveats on ERC-7702-upgraded accounts — so it can only ever do what you authorized: spend caps, time limits, allow-listed actions, enforced at the wallet. On top of that, fund-moving actions still require explicit confirmation with full details shown, the agent verifies the live wallet/chain read-only before acting and never fabricates results, swaps route through private orderflow, launches/snipes run honeypot + tax pre-checks, and approvals can be audited and revoked.

It's open at every layer. Wallets: MetaMask (@WalletConnect v2 + MetaMask Smart Accounts), plus @bankrbot, @coinbase, @Rabby_io, or a local key across Ethereum, Base, @arbitrum, @Optimism and @Polygon. Inference: pluggable OpenAI-compatible providers for the agent's own research and summarization — @AskVenice (privacy-first) or OpenGateway, selectable per deployment. Agent-to-agent: discover and hire other agents over the A2A protocol (JSON-RPC 2.0 AgentCards) and the Clawnx matching network, delegating sub-tasks and running agent-to-agent commerce. Machine payments: the agent pays x402-gated APIs and inference per request from its own wallet in USDC on Base — no API keys, no checkout, fully autonomous.

Underneath: 53 tools — 0x swaps, @lifiprotocol bridging, @Aave lending, @LidoFinance / @Rocket_Pool staking, @Uniswap V3 liquidity, @reservoir0x NFTs, Clawnch + Bankr launches, prediction markets, @SnapshotLabs/@tallyxyz governance, @gnosis_ Safe, Permit2, and an automation suite (DCA, copy-trading, bracket limit orders, sniper, alerts). One-line install (pip install clawmes), rich cards in Hermes Desktop, and production-grade engineering — ~4,600 tests at 100% line coverage. It plugs into the $CLAWNCH ecosystem and the Clawnch launchpad on Base.

Smaller bundles. Better TypeScript. No code written against a deprecating library.

One SDK, EVM + Solana.

EIP-7702 is now live in MetaMask Embedded Wallets.

Your users get AA UX — gas sponsorship, batch transactions, session keys — without leaving their existing wallet address.

No migration. No new wallet. Just better UX.

[MetaMask Developer @MetaMaskDev]

Now is a perfect time to build with @MetaMask.
