Get paid, earn points and extend credit, with Arbitrum under the hood.
AI agents that get work done within your budget and rules.
Encrypted privacy-preserving DEX (eAMM)
Permit is programmable payment authorization infrastructure that lets software and AI agents make payments without giving them unrestricted access to a user's wallet.
Metaverse with focus on professional networking
StylusSafe is a next-generation Intent-Based Smart Wallet that makes blockchain boundaries completely invisible. By combining ZeroDev (ERC-4337 Account Abstraction), Passkey Authentication (WebAuthn), and Li.Fi Aggregation Engine, it solves the biggest friction point in crypto today: Cross-Chain Swaps.
Knock-out leverage on NVDA in USDG, live on Robinhood Chain mainnet. Its vault is never short: every position is bought as real NVDA and held, and the most you can lose is your margin.
Self-custodial payments on Arbitrum. Get paid with a link or a QR code, send to a username, and skip the seed phrases and gas. Your money stays yours.
Idle business cash earns fees on tokenised stocks (Robinhood Chain), with price risk hedged on Hyperliquid and shown by a public Proof of Hedge. Non-custodial, MiCA-authorised. Returns are variable.
Set. Forget. Earn — on real US stock tokens, not only crypto pools. AXIS already ships gasless Google login yield on Arbitrum One (UXmaxx winner). For Open House we put US stock-token baskets under that same door: say “tech yes, oil no,” get a Robinhood Chain practice basket, and a weekly English note that shows the after-hours/weekend print next to Thursday’s close.

One command to start an Arbitrum Stylus (Rust) project that deploys on the first try: 9 tested templates (tokens, NFTs, vault, escrow, payment streams, oracle, interop, faucet), USDG presets for Arbitrum One and Robinhood Chain, and an MCP server for AI agents.
A provably fair treasure hunt on Arbitrum, paid in USDG. The hider seals the board on-chain, every clue is checked by Merkle proof, and a lying or vanishing hider is slashed. No trusted server.
