## Products

- [HOT Wallet](https://thegrid.id/profiles/hot_labs): HOT Wallet is a non-custodial multi-chain wallet integrating directly into Telegram Mini Apps and available as a browser extension. The wallet enables asset management across multiple chains and EVM-compatible networks through a unified interface. Features include built-in DEX aggregation for token swaps, cross-chain bridging, NFT support, staking pools, and fiat on-ramps via debit cards. The wallet stores private keys locally on user devices with optional MPC security layer, password protection, and 2FA authentication. Users access the wallet through Telegram handles formatted as username.tg addresses on supported blockchains. (Wallet, Live, Main Product)
- [HOT Protocol](https://thegrid.id/profiles/hot_labs): HOT Protocol is a cross-chain infrastructure layer combining smart contracts and off-chain services to provide chain signature functionality for programmable wallets. It distributes private key segments across independent validator nodes using multi-party computation, enabling secure transaction signing across many blockchains without a single point of failure. The protocol supports chain abstraction through a bridging system that lets tokens move between chains while retaining their value, along with a lightweight developer connector for embedding multi-chain wallet access into third-party applications. Validators participate in signing by staking the protocol's native token and communicate over end-to-end encrypted channels. (Cross-chain Infrastructure, Live)
- [HOLD Wallet](https://thegrid.id/profiles/hot_labs): HOLD Wallet is a hardware cold wallet for holding cryptocurrency in offline storage. It provides users with a physical device for securing private keys away from internet-connected environments, complementing the software-based wallet offering. (Live)
- [HOT Pay](https://thegrid.id/profiles/hot_labs): HOT Pay is a non-custodial crypto payment gateway for websites and Telegram Mini Apps. It lets merchants accept payments in a wide range of tokens across multiple chains, automatically routing and converting incoming funds into the merchant's chosen settlement currency. Payments settle directly to the merchant's own wallet rather than passing through an intermediary custodian, and integration is designed to be completed quickly through embeddable checkout widgets, payment links, or an API with webhooks.

## Assets

- [HOT (HOT)](https://thegrid.id/profiles/hot_labs): HOT is the utility token of the HOT Protocol, a chain abstraction and MPC signing network built by HOT Labs. It is used to pay for transaction signing, stake as collateral for validators and gatekeepers, and receive rewards for processing signature requests across supported chains. The token also functions as a universal gas currency, letting users pay network fees on any supported chain and participate in governance and incentive programs. (Utility)
