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.
Mercuryo
Mercuryo operates as a primary bridge between conventional fiat banking systems and non-custodial cryptocurrency ecosystems. Established in 2018 and headquartered in the United Kingdom, the platform specializes in embedded payment infrastructure that enables individual users to buy and sell digital assets directly through integrated partner interfaces. Rather than acting as a standalone trading exchange or long-term wallet custodian, it focuses strictly on transactional execution.
For everyday users interacting with decentralized applications or self-hosted wallets, Mercuryo delivers substantial convenience by eliminating intermediary deposit steps. However, that seamless payment flow comes with tradeoffs in the form of variable card processing fees and network transmission costs. It is fundamentally engineered for rapid entry and exit transactions where execution immediacy outweighs the ultra-low basis point fee structures typical of dedicated spot trading order books.
