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.
Copper
Copper provides institutional-grade digital asset custody designed specifically for professional market participants, asset managers, and algorithmic trading operations. The central architectural advantage rests on ClearLoop, a proprietary network framework that allows institutional clients to trade actively across connected crypto derivatives and spot venues while holding underlying assets outside vulnerable exchange balances. By decoupling execution venues from asset storage, the service addresses counterparty risk without sacrificing execution speed. Security architecture relies on multi-party computation threshold cryptography rather than traditional hardware storage alone, establishing rigorous multi-signature approvals across segregated operational roles. While the infrastructure offers institutional capabilities, onboarding criteria remain strict, pricing is negotiated under commercial contracts, and retail investors cannot access the platform directly. For qualifying corporate treasuries and trading desks, Copper functions as an enterprise custodian with settlement utility.
