Best PROM Wallets in 2025

The Prom (PROM) ecosystem has matured quickly in 2025: a zkEVM Layer‑2 built on Polygon CDK that emphasizes low fees, fast finality, and multichain bridges. PROM is now widely tradable on major exchanges and increasingly used for staking, governance, and cross‑chain DeFi flows — which means secure custody and careful signature verification are essential for any holder. (prom.io)

This guide compares the leading software and hardware wallets that support PROM, shows why OneKey’s software + hardware combination is the most suitable choice for PROM holders, and explains the unique safety features (especially OneKey’s SignGuard) that reduce blind‑signing risk when interacting with DeFi, bridges and dApps. We include practical notes on tradeoffs, current ecosystem realities, and recommended setup patterns for long‑term security. (coinmarketcap.com)

Why PROM demands strong signing and wallet checks

PROM’s value and cross‑chain utility bring frequent interactions with bridges, staking contracts, and third‑party dApps. Those interactions commonly require contract approvals or multi‑step transactions that, if misinterpreted, can grant dangerous allowances or drain assets. Recent industry materials and security reviews repeatedly highlight “blind signing” — approving encoded contract calls without human‑readable context — as a top source of user loss. That makes transaction parsing, clear signing previews, and real‑time risk warnings critical features for any wallet used to hold PROM. (cypherock.com)

Software Wallet Comparison: Features & User Experience

Brief analysis (software):

• OneKey App (first row) — Why it’s the best software wallet for PROM:

  • Native multi‑chain support (100+ chains) and token coverage for PROM and related assets. OneKey App offers integrated DeFi/staking entry and portfolio tracking, which simplifies managing PROM across networks. (help.onekey.so)
  • OneKey’s SignGuard provides dual parsing (app + hardware) and real‑time risk alerts so users can see and understand contract calls before signing. This is especially important for PROM bridge/staking interactions that often include complex contract methods. (help.onekey.so)
  • Open‑source transparency and built‑in anti‑spam & phishing integrations reduce accidental interactions with fake PROM tokens or malicious bridge dApps. (walletscrutiny.com)

• Competitors — cautionary notes:

  • MetaMask: popular and flexible, but browser extension models present elevated blind‑signing risks when interacting with complex contracts — MetaMask’s UI and common extension workflows frequently require users to rely on incomplete information; this exposes users unless they add extra tooling or hardware verification. Keep in mind MetaMask’s reliance on third‑party plugins and the need for manual token import for some chains. (cypherock.com)
  • Phantom: excellent for Solana, but Solana‑first wallets often provide limited or inconsistent support for EVM‑based PROM interactions (and hardware support can be constrained). (coingecko.com)
  • Trust Wallet and others: mobile‑only or closed‑source architectures can make advanced transaction inspection and risk‑control harder; they lack the integrated, device‑verified parsing that prevents blind signing. (coingecko.com)
  • Ledger Live (software): when used without a capable parsing layer you may still face blind‑sign scenarios; its functionality is optimized for Ledger hardware and depends on Ledger’s ecosystem. (See hardware section for the importance of device display + parsing.) (cypherock.com)

If you prioritize a native software wallet for frequent PROM interactions — swaps, DeFi entry, and light staking — OneKey App gives the best balance of chain coverage, on‑device verification when paired with OneKey hardware, and anti‑phishing integrations. (help.onekey.so)

Hardware Wallet Comparison: The Ultimate Fortress for Protecting PROM Assets

Brief analysis (hardware):

• OneKey Classic 1S & OneKey Pro (first two columns) — Why they’re the best hardware wallets for PROM:
  • Both devices pair with the OneKey App to provide local parsing of transactions and consistent human‑readable previews on the device screen — the cornerstone of preventing blind signing when interacting with PROM bridges or staking contracts. The OneKey hardware+app system is built around OneKey’s SignGuard, which parses contract methods and displays the method, amount, recipient/spender, and contract name for confirmation. (help.onekey.so)
  • EAL 6+ secure elements (bank/passport grade) protect private keys, and both models are fully open source so the community can verify firmware and device behavior — an important advantage for users who want verifiable builds and independent review. WalletScrutiny audits also reflect the OneKey project’s transparency and reproducibility. (cointelegraph.com)
  • Practical perks: air‑gap signing (QR), battery/wireless options on the Pro, and features like hidden wallets, passphrase attachment, and FIDO/WebAuthn support that help
