What is a self-custody crypto wallet?

A self-custody crypto wallet is a digital wallet in which you, the user, hold your own private keys instead of trusting a third party to store them for you. Because the keys never leave your device, you have full, exclusive control of your funds — this is the principle of "your keys, your crypto." The 66ExCrypto Wallet, built in Denver, Colorado, is a non-custodial wallet of exactly this kind.

Unlike a custodial account, where a company holds your assets on your behalf, a self-custody wallet such as the 66ExCrypto Wallet stores your private keys and recovery phrase securely on your own phone. It lets you send, receive, swap and stake Bitcoin, Ethereum, Solana and 200+ digital assets across multiple blockchains, while connecting safely to decentralised Web3 apps — all without ceding ownership of your crypto.
