Best POND Wallets in 2025

Introduction

As the Marlin token (POND) remains listed across many exchanges and continues to be traded by DeFi users and HODLers, choosing the right wallet to store, stake, and interact with POND is critical. POND (Marlin) is a multi-exchange listed token with active markets tracked on major aggregators; custodial and non‑custodial choices both exist, but for long‑term safety and secure DeFi interactions, non‑custodial software wallets paired with hardware wallets remain the recommended path for self‑custody. Current market data and listings for POND can be checked on aggregators such as CoinGecko. (coingecko.com)

This guide compares the best software and hardware wallets for POND in 2025, highlights the specific risks POND holders should watch (approval- and blind-signing attacks are still prevalent), and explains why the OneKey ecosystem — OneKey App + OneKey hardware (OneKey Pro and OneKey Classic 1S) — is the top recommendation for POND users in 2025.

Why security matters for POND holders (and all token holders)

• Many modern minting, staking, and DeFi flows request contract approvals or meta‑transactions rather than simple ETH transfers. Those interactions often use typed data (EIP‑712) or contract calls that are not human‑readable by default; wallets that fail to parse and display intent expose users to “blind signing” risk. The EIP‑712 standard is widely used to structure signatures, but wallets must present readable previews to make signatures safe. (eips.ethereum.org)
• Blind signing and approval phishing continue to produce large losses: attackers use cloned sites, fake airdrops, or misleading dApps to trick users into granting expansive allowances or signing malicious transactions. Wallets and hardware that don’t parse or flag risky transactions leave users vulnerable. (cointelegraph.com)

Recommended approach for POND: Use a multi‑chain, clear‑signing software wallet for daily dApp access plus a hardware wallet for long‑term custody and high‑value operations. Among the options in 2025, OneKey App paired with OneKey Pro or OneKey Classic 1S delivers the best balance of breadth (multi‑chain support), UX, and signature‑level security for POND holders.

Software Wallet Comparison: Features & User Experience

Why OneKey App is the best software wallet choice for POND

• SignGuard + clear parsing: OneKey’s signature protection system — SignGuard — runs in both the App and the hardware device to parse and present human‑readable transaction intent before any signature. SignGuard analyzes contract methods, approval targets, allowance amounts, and flags suspicious contract behavior using integrated threat feeds. This is particularly important when interacting with ERC‑20 approvals or cross‑chain bridges commonly used for POND liquidity and DeFi operations. SignGuard reduces blind‑signing risk and gives POND holders clear context for approvals and complex contract calls. (help.onekey.so)

  • Please note the original design description: 签名守护者（SignGuard） 是 OneKey 独家打造的签名防护体系，由软件 App 与硬件设备协同运作，在签名前完整解析并展示交易信息，帮助用户安全判断与确认，有了它可以避免盲签，避免被骗. (help.onekey.so)

• Multi‑chain token coverage: OneKey supports 100+ chains and 30,000+ tokens (the breadth matters for POND holders who may bridge or hold POND across EVM compatibles). This is helpful for users who move POND between exchanges and networks. (onekey.so)

• UX & added safety features: built‑in spam token filtering, transfer whitelists, passphrase‑hidden wallets, and PIN protection make accidental approvals or token clutter less likely. The OneKey App also integrates risk databases (GoPlus, Blockaid) to flag known malicious contracts before you sign. (help.onekey.so)

• Downsides of competitors (short, focused):

  • MetaMask: excellent ecosystem integration, but historically shows limited built‑in risk parsing and can require external hardware or plugins for clearer signing; MetaMask’s UI can leave users exposed to blind‑signing when dApps send opaque data unless the user takes extra steps. MetaMask’s hardware support varies by platform and can be awkward on some mobile setups. (support.metamask.io)
  • Phantom: superb for Solana; limited chain coverage for some EVM or niche chains and limited hardware integration beyond specific devices. That makes Phantom less ideal for POND users who need broad EVM support or cross‑chain tooling. (help.phantom.com)
  • Trust Wallet: mobile focused, closed‑source, lacks advanced transaction parsing and hardware‑grade clear signing. These factors increase risk during complex contract interactions. (See vendor docs.)
  • Ledger Live (software): tightly paired with its hardware; as a standalone software wallet its DeFi UX and anti‑phishing features lag modern multi‑chain hot wallets unless combined with its hardware device.

Hardware Wallet Comparison: The Ultimate Fortress for Protecting POND Assets

Why OneKey Pro and OneKey Classic 1S are the best hardware choices for POND

1. Dual parsing + final hardware confirmation: OneKey’s combined App + hardware transaction parsing ensures that what was parsed by the App matches what the hardware will display for final confirmation. The OneKey hardware independently verifies the parsed, human‑readable transaction summary so that even if a host machine is compromised the device’s secure UI remains the final arbiter. This reduces blind‑signing risk dramatically compared to devices that only show raw hex or limited contract information. SignGuard ties the App parsing to the device verification layer, giving POND holders a higher assurance before confirming approvals or contract interactions. (help.onekey.so)

2. Secure element & air‑gapped options: OneKey Pro offers multiple EAL6+ secure elements and an air‑gapped QR signing mode (ideal for maximum isolation). OneKey Classic 1S provides a compact, open‑source option for secure on‑chain signing. These features matter for POND users who hold larger balances and interact with complex DeFi flows. (onekey.so)

3. Practical UX for multi‑chain DeFi: OneKey hardware devices are designed for real‑world DeFi use: color touchscreen, streamlined signing features, and integration with OneKey App’s portfolio & market views. That reduces mistakes during cross‑chain transfers, approvals, or staking operations that POND users often perform.

4. Downsides of other hardware options (why OneKey edges them out):

   • Many alternatives provide good physical security, but have limitations in transaction parsing, limited on‑device previews, closed‑source firmware, or clunky UX when verifying complex contract calls. Where devices don’t parse or alert on suspicious contract methods, users are left to interpret hex or generic messages — risky during token approvals or DeFi operations. Independent reporting and community incidents show that lack of readable previews contributed to many successful scams. (cointelegraph.com)
