Our take
coin98
Coin98 operates as a non-custodial Web3 wallet designed for individuals who interact across disparate decentralized ecosystems. By combining EVM compatibility with non-EVM chains like Solana, Near, and Polkadot, it removes the friction of maintaining distinct software tools for separate networks. Because users keep personal possession of their recovery phrases, account security relies directly on personal key handling rather than third-party custodial storage. The platform integrates decentralized swap aggregators, making it convenient to trade assets across chains directly from mobile, browser extension, or web interfaces. While the software layer is free to install, on-chain activity remains subject to network gas volatility and decentralized protocol liquidity limits. It represents a versatile self-custody hub for experienced decentralized finance users seeking multi-chain reach without surrendering asset custody.
Keystone
Keystone, formerly Cobo Vault, offers a dedicated approach to cold storage by maintaining complete physical separation from network-connected hardware. By eliminating USB data transmission, Bluetooth radios, Wi-Fi antennas, and cellular components, the Keystone 3 Pro isolates cryptographic seed material from typical remote vector attacks. Users navigate transaction details on an expansive four-inch color touchscreen, verifying smart contract parameters before signing via bidirectional animated QR codes.
While this architecture significantly reduces remote exploitation pathways, it places transaction formatting and portfolio management entirely on third-party software interfaces such as MetaMask, Sparrow, or Rabby. Keystone delivers a thoughtfully constructed, open-source-leaning physical framework suitable for intermediate to advanced crypto holders seeking robust self-custody controls, though newer participants may experience a brief learning curve when managing pairing workflows across disparate software companions.
