Users can store, send, and receive digital assets across multiple chains. Features include staking for Solana, Cardano, and Flow; DApp connectivity with Wallet Emulation mode; an NFT gallery spanning multiple chains; an integrated crypto exchange with buy, sell, and swap; social account login via Web3auth without a seed phrase; and hardware wallet support for Ledger, Trezor, GridPlus, Keystone, OneKey, and BitBox02. Real-time transaction scanning provides phishing, spam, and malicious address protection. (Wallet, Live, Main Product) - [Cardano MetaMask Snap](https://thegrid.id/profiles/nufi): Cardano MetaMask Snap is a MetaMask Snap that adds Cardano blockchain support to MetaMask wallet (version 12 and above). When installed, it derives a Cardano account from the MetaMask seed phrase, enabling MetaMask users to send, receive, and stake ADA, swap Cardano tokens via a DEX aggregator, and connect to Cardano dApps. Transaction signing occurs within MetaMask's native interface, keeping private keys within MetaMask. A NUFI widget bridges MetaMask and connected Cardano dApps. (Wallet, Live) - [NUFIConnect](https://thegrid.id/profiles/nufi): NUFIConnect is an SDK that lets Cardano dApp developers onboard Web2 users through social account login (Google, Discord, X, Facebook) without requiring a separate wallet installation. When a user authenticates, NUFIConnect creates a non-custodial Cardano wallet in the background using distributed key management through Torus/Web3auth. Users interact with dApps via a wallet widget and can manage Cardano assets, buy, and swap tokens. The same wallet connects across all integrated dApps. (Embedded Wallet, Live) - [NUFI Validator Nodes](https://thegrid.id/profiles/nufi): NUFI Validator node operations on the Cardano, Solana, and Flow blockchains, accepting stake delegations from token holders. On Cardano, NUFI manages multiple block producer and relay nodes deployed via Google Cloud Platform using Terraform and Ansible. Solana validators run on custom hardware with primary and secondary nodes for high availability. Flow verification nodes operate in GCP Cloud. All infrastructure is monitored through Grafana Cloud.
