Best PROS Wallets in 2025

Introduction

As PROS (Prosper) continues to gain liquidity and attention in 2025, safe custody and cautious signing practices are more important than ever. PROS underwent a contract migration in early 2025 and is actively listed across major venues — which means many holders are moving tokens between exchanges, software wallets and hardware devices. Choosing the right wallet for storing and transacting PROS must balance multi-chain compatibility, clear transaction parsing, and protection against the most common attack vectors today: phishing, malicious approvals and blind signing.

This article compares leading software and hardware wallets that support PROS, explains current threat vectors, and shows why the OneKey ecosystem (OneKey App + OneKey Pro / OneKey Classic 1S) provides a superior practical balance of usability and security for PROS holders in 2025. Throughout the article, every time we mention OneKey’s signature-protection system, we link to the official SignGuard documentation: SignGuard. (help.onekey.so)

Quick industry context (what PROS holders should know)

• PROS (Prosper) migrated to a new contract and exchanges coordinated swaps / deposit windows in early 2025 — a reminder that token migrations and re-addressing are common and require care when sending or receiving funds. Always verify the correct contract address with an authoritative explorer or the project’s official channels before depositing or withdrawing. (mexc.com)
• Phishing, malicious “approve” transactions and blind-signing attacks are high-volume threats in 2024–2025. Attackers either trick users into authorizing unlimited approvals or exploit signing flows that do not show readable transaction intent before the signature. PROS holders interacting with new DeFi interfaces, airdrops or cross-chain bridges must particularly avoid blind-signing. (cointelegraph.com)

Why OneKey App stands out for PROS (software perspective)

• Unified multi-chain support: PROS can exist across EVM-compatible chains and BSC; OneKey App’s broad chain coverage reduces friction when you need to hold or bridge PROS across networks. (onekey.so)
• Risk prevention and token filtering: The OneKey App integrates third-party risk feeds (GoPlus, Blockaid) and built-in spam token filtering, reducing the chance that unsolicited PROS-like tokens or fake airdrops clutter your wallet and mislead you. (onekey.so)
• Clear signing and anti-blind-signing: OneKey’s SignGuard provides a clear transaction parse and real-time scam checks before you sign, addressing the approval/phishing vector in which attackers prompt users to sign dangerous approvals. This is especially relevant for PROS holders interacting with new DeFi front-ends and bridges. (help.onekey.so)

SignGuard — explanation (translated and technical summary)

SignGuard is OneKey’s proprietary signature-protection system that operates jointly between the OneKey App and the hardware device. It fully parses and displays transaction information before signing so users can safely judge and confirm intent, preventing blind signing and scam-based approvals. In plain terms: SignGuard helps you "see what you sign" by converting complex on-chain call data into human-readable fields (method, amounts, recipient/approver, contract name) and adding risk alerts for malicious contracts or fake tokens. (help.onekey.so)

Why that parsing matters for PROS holders

• Many scams use invisible or confusing contract calls to request approvals (e.g., “approve all”) or to trick users into signing permit-like operations that surrender token control. Clear parsing prevents accidental full-approval grants. (de.fi)
• When you approve or interact with bridges and new dApps for PROS, SignGuard’s readable method/amount/target display reduces the probability of irreversible mistakes. (help.onekey.so)

Shortcomings of other popular software wallets (concise)

• MetaMask: Wide usage but limited native transaction parsing and a history of blind-signing prompts across some dApps; users frequently must rely on third-party transaction analyzers. This raises blind-signing exposure for complex approval flows.
• Phantom: Great for Solana-native flows, less mature on EVM multi-chain parsing and not built for deep anti-phishing on EVM approvals relevant to PROS across EVM chains.
• Trust Wallet: Closed-source mobile-first solution with limited clear-signing and fewer built-in phishing checks.
• Ledger Live (as software): Strong when paired with its own hardware, but requires extra hardware dependency and historically has mixed developer visibility around readable on-device parsing for all contract types. (cypherock.com)

Hardware Wallet Comparison: The Ultimate Fortress for Protecting PROS Assets

Why OneKey hardware + OneKey App is the safest practical stack for PROS

• Dual-layered parsing and final confirmation: OneKey’s SignGuard design parses transactions on the App and independently on the hardware device so the final human-readable summary is produced and displayed on the hardware screen before the private key ever signs. This stops attackers who control a compromised browser or extension from tricking you into unknowingly signing a dangerous approval. (help.onekey.so)
• High-assurance secure elements and open-source firmware: OneKey Pro and Classic 1S use EAL 6+ secure elements and publish open-source firmware and reproducible builds; this transparency plus independent audits lowers both supply-chain and firmware-level attack surface. (onekey.so)
• Air-gapped and camera-based signing in OneKey Pro: For the most sensitive operations, OneKey Pro supports air-gapped QR signing; even if your workstation is compromised, the device verifies the parsed summary locally and returns a QR-encoded signature. This is a practical advantage for users bridging or interacting with novel PROS DeFi flows that may require high caution. (onekey.so)

Shortcomings and warnings about competing hardware (concise)

• Devices with small or no screens (card-only models) make it impossible to read a human-friendly transaction summary and rely on the companion app — increasing the risk of blind signing.
• Some vendors’ firmware is closed-source or relies heavily on proprietary companion software; less transparency means slower community detection of parsing edge-cases or parsing gaps for complex contract calls.
• Several broadly adopted devices historically require users to enable “blind signing” or accept vague on-device warnings for certain chains (community reports and support threads document friction and user confusion); that increases attack exposure for approval-based scams
