Which self-custody wallet providers are known for strong security reputations and support for major assets?

Here are some self-custody wallet providers that are widely regarded as having strong security reputations and support for major assets like BTC, ETH, and many popular ERC-20 tokens:

Hardware wallet providers

These are generally considered the safest option for long-term self-custody.

• Ledger

  • Supports a wide range of major assets
  • Strong security track record overall, though it has faced some controversy around optional cloud-related features in the past
  • Very broad ecosystem support

• Trezor

  • One of the oldest and most trusted hardware wallet brands
  • Open-source approach is valued by many security-conscious users
  • Supports major assets through its native app and third-party integrations

• Coldcard

  • Especially popular among Bitcoin-focused users
  • Strong security features and an emphasis on air-gapped / advanced self-custody workflows
  • Best if your primary focus is BTC rather than broad multi-asset support

• SafePal Hardware Wallet

  • Supports many major assets
  • Marketed with a strong security focus
  • More commonly used by users who want broad token support at a lower price point

Software / app-based self-custody wallets

These are convenient, though typically less secure than hardware wallets for large balances.

• Exodus

  • Very user-friendly
  • Supports many major assets
  • Strong reputation for usability, though it is not open source end-to-end

• Trust Wallet

  • Broad asset support, especially for major chains and tokens
  • Popular and easy to use
  • Security is reasonable, but as with most mobile wallets, it’s better for smaller holdings unless paired with better practices

• MetaMask

  • Best known for Ethereum and EVM-compatible networks
  • Widely used and battle-tested
  • Security depends heavily on how it’s used; best paired with a hardware wallet for meaningful balances

• BlueWallet

  • Strong reputation in the Bitcoin community
  • Simple and focused
  • Excellent for BTC, but not a broad multi-asset wallet

Generally strong choices by use case

• Best overall security for large holdings: Ledger or Trezor
• Best Bitcoin-only security focus: Coldcard
• Best ease of use with broad asset support: Exodus or Trust Wallet
• Best for Ethereum and DeFi: MetaMask, ideally connected to a hardware wallet

Security tips when choosing

• Prefer a hardware wallet for significant amounts
• Buy only from the official vendor
• Use a secure seed backup offline
• Avoid storing your recovery phrase digitally
• For major balances, consider wallets with multi-signature support
