Company profiles

Binance

Binance is a centralized cryptocurrency exchange, launched in July 2017 by Changpeng Zhao, that offers spot, futures, earn and payment products through Binance.com and its app. Binance.com now runs its regulated activities through three entities licensed in Abu Dhabi Global Market and is closed to US residents, who are served instead by the separate affiliate Binance.US.

Gemini

Gemini is a US cryptocurrency exchange and custodian founded in 2014 by Cameron and Tyler Winklevoss, offering an app, the ActiveTrader platform, custody, staking and a crypto-rewards credit card. Its parent, Gemini Space Station, Inc., has been listed on Nasdaq as GEMI since September 2025, and US customers contract with either Gemini Trust Company, LLC or Gemini Moonbase, LLC depending on their state.

Kraken

Kraken is a centralized cryptocurrency exchange where customers buy, sell, trade and hold crypto through the Kraken app and the Kraken Pro trading platform. It is run by Payward, Inc., a Delaware-incorporated company, through regional subsidiaries such as Payward Interactive in the US and Payward Europe Solutions in the European Economic Area, so the entity, licence and product list you get depend on where you live.

Ledger Nano Gen5

The Ledger Nano Gen5 is a $179 hardware wallet with an E Ink touchscreen that keeps crypto private keys in a certified secure chip and connects to the Ledger Wallet app (formerly Ledger Live) by USB-C or Bluetooth. It is made by Ledger SAS, a Paris company founded in 2014, which announced the device in October 2025.

Trezor Safe 5

The Trezor Safe 5 is a touchscreen hardware wallet that keeps private keys on the device and signs transactions over USB-C, using an EAL6+ certified secure element to guard the PIN. It is made by Trezor Company s.r.o., the Prague company behind the Trezor brand since 2013, and is used with Trezor's own Suite app or compatible third-party wallets.

MetaMask

MetaMask is a self-custodial crypto wallet for browsers and phones that holds your keys on your device and connects you to Ethereum-compatible networks, Solana, Bitcoin and TRON. It is developed by Consensys Software Inc., which does business as MetaMask, and the swaps, perps, card and staking features inside it are largely run by third parties.

Phantom

Phantom is a self-custodial crypto wallet for mobile and desktop browsers that started on Solana and now also supports Ethereum, Bitcoin, Base, Polygon, BNB Chain and other networks. It is made by Phantom Technologies, Inc., a venture-backed US company, which says it never has access to user funds, though its Cash account, perps and card features add other providers and country limits.

Trust Wallet

Trust Wallet is a self-custodial multichain crypto wallet for iOS, Android and desktop browsers that keeps your keys on your device and routes swaps, purchases and staking to third-party providers. Binance bought it in 2018 but says it no longer owned or controlled it as of 15 May 2025, and Trust Wallet's terms do not name the legal entity behind it.

Uniswap

Uniswap is a decentralized exchange protocol that lets people swap tokens from their own wallets against pools of liquidity, priced by an automated market maker rather than an order book. The protocol is a set of smart contracts governed by UNI token holders; Uniswap Labs, a New York company, builds the main web app, wallet and much of the code, and the Uniswap Foundation supports governance.

Gemini Dollar (GUSD)

Gemini Dollar (GUSD) is a US dollar stablecoin on Ethereum, backed 1:1 by cash, government money market funds and short-dated Treasury bills. It is issued by Gemini Trust Company, LLC, a New York-chartered trust company owned by Nasdaq-listed Gemini Space Station, Inc., and only Gemini customers can create or redeem it for dollars.

Ripple USD (RLUSD)

Ripple USD (RLUSD) is a US dollar stablecoin backed by cash, short-term US Treasuries and government money market funds, and it runs on the XRP Ledger, Ethereum and several Ethereum-compatible networks. It is issued by Standard Custody & Trust Company, LLC, a New York trust company owned by Ripple Labs, and it is a separate asset from XRP.

Tether (USDT)

Tether (USDT) is the US dollar stablecoin issued by the Tether group, whose customer-facing entity is Tether International, S.A. de C.V. in El Salvador. Each token is meant to be backed by reserves worth $1, but only verified Tether customers can redeem directly, with a $100,000 minimum, so most people buy and sell USDT on exchanges.

USD Coin (USDC)

USDC (USD Coin) is a US dollar stablecoin issued by Circle. Its reserves are held mostly in a BlackRock-managed money market fund and partly as cash at large banks, and it runs on 38 blockchains. Only vetted businesses with a Circle Mint account can mint or redeem USDC directly, so most people buy and sell it through exchanges and apps.

Aave

Aave is a non-custodial lending protocol: smart contracts on Ethereum and other networks where users supply crypto to earn interest or borrow against collateral. AAVE token holders govern it through the Aave DAO; Aave Labs, a separate company, builds the main app and interface but says it does not own or control the protocol.

Crypto.com Visa Card

The Crypto.com Visa Card is a prepaid card that you top up from the Crypto.com app, with five tiers whose rewards depend on a Level Up subscription or a 12-month lockup of the CRO token. It is issued by a different licensed company in each region, such as Community Federal Savings Bank in the US and Foris MT Limited in the EEA, and it is separate from the newer US-only Crypto.com credit card.

TradingView

TradingView is a charting, screening and market-analysis platform for stocks, crypto, forex and futures, with a free tier and paid plans. It is run by TradingView, Inc., which gives a New York address in its terms, and it does not hold customer funds: trades placed from its charts go to a separately connected broker or exchange.

OpenSea

OpenSea is a marketplace for buying, selling and minting NFTs that now also offers token swaps and perpetual futures across more than 25 blockchains. It is operated by Ozone Networks, Inc., which Devin Finzer and Alex Atallah founded in 2017, and it never takes custody of the assets traded on it.

Hyperliquid

Hyperliquid is a layer-one blockchain with its own onchain order-book exchange, HyperCore, for perpetual futures and spot trading, plus an Ethereum-compatible smart contract layer called HyperEVM. Core development is led by the self-funded Hyperliquid Labs, the web app is offered by Hyperliquid Corp., the Hyper Foundation supports the ecosystem, and the network is secured by validators staking the native HYPE token.
