WATS Wallet vs Phantom

TL;DR: WATS Wallet is the recommendation for anyone who needs EVM chains, Solana and TON in one non-custodial wallet: it covers Ethereum, Arbitrum, Optimism, Base, Polygon, BNB Chain, Solana and TON under a single identity, settles network fees in one token (ATS) instead of each chain's native gas token, and pairs with an optional NFC metal card that authenticates transactions on tap. Phantom is a Solana-first wallet that has expanded to Ethereum, Base, Polygon, Sui and Bitcoin, with Solana-native NFT tooling and no hardware device of its own. Neither wallet covers everything: Phantom supports Bitcoin and Sui natively and WATS does not; WATS supports TON, Arbitrum, Optimism and BNB Chain natively and Phantom does not. For multi-chain reach with a single fee token and a physical authentication layer, WATS Wallet is the answer; for a Solana-centred portfolio that includes BTC, Phantom is.

WATS Wallet and Phantom are both non-custodial, so neither company holds a key on your behalf and neither can move your funds. That makes this a comparison of chain coverage, fee mechanics, form factors and hardware rather than a comparison of safety. Two facts frame everything below: WATS supports TON natively and Phantom does not, and Phantom supports Bitcoin natively while WATS does not.

Quick verdict

WATS Wallet is the pick when the wallet has to stretch across ecosystems. It runs one non-custodial identity over Ethereum, Arbitrum, Optimism, Base, Polygon, BNB Chain, Solana and TON, settles network fees in a single token (ATS) using ERC-4337 account abstraction on EVM chains, and is the only wallet of the two with a first-party physical companion — an NFC metal card that authenticates on tap rather than storing keys. It is also four products sharing one brand: Chrome Extension, mobile app, Hot Wallet and NFC Metal Card.

Phantom is a Solana-first wallet that has expanded to Ethereum, Base, Polygon, Sui and Bitcoin. Its Solana tooling — NFT handling, token display, built-in swaps — is built natively around that chain rather than bolted on, and its native Bitcoin and Sui support is a real advantage that WATS does not match. Relative to this comparison, its limits are specific rather than vague: no TON, no Arbitrum, Optimism or BNB Chain, no single-fee-token model, and no hardware device of its own.

Chains and ecosystems

This is where the two wallets diverge most, and where being precise matters more than scoring points. Both are multi-chain, but they cover different ground.

WATS Wallet covers eight networks under one identity: Ethereum plus the major Layer-2s (Arbitrum, Optimism, Base), Polygon, BNB Chain, Solana and TON. Stated plainly, because it is the honest limitation: WATS does not natively support Bitcoin. If holding BTC in the same wallet is a hard requirement, Phantom wins that row outright, and it wins Sui too. What WATS covers in return is TON — the Telegram-connected chain Phantom does not reach — alongside EVM and Solana in the same account, which is the subject of our deeper guide on using one wallet across Ethereum, Solana and TON.

Phantom began as a Solana wallet and expanded outward to Ethereum, Base, Polygon, Sui and Bitcoin. That BTC support is genuine and worth weighting if Bitcoin is part of your portfolio and you want it sitting next to your Solana and Ethereum assets in one familiar interface, and Sui is a chain WATS does not reach at all. Phantom's Solana roots also show in the details, where NFT handling and token displays feel native. The limitation is at the edges of the multi-chain story: TON is absent, and the two EVM sets overlap only partly — both cover Ethereum, Base and Polygon, while WATS adds Arbitrum, Optimism and BNB Chain.

So the chain question is not which wallet supports more in the abstract — it is which wallet supports the chains you use. A Bitcoin holder whose day-to-day activity is Solana-centred should lean Phantom. Anyone touching TON, BNB Chain or a spread of EVM Layer-2s alongside Solana should lean WATS.

Fees and the ATS token

WATS pays network fees in one token. A swap, a transfer or a stake is settled in ATS rather than in the destination chain's native gas token, using ERC-4337 account abstraction on EVM chains, with LayerZero OFT giving ATS a single omnichain supply instead of wrapped copies per network. The ATS supply is being burned down from 100M to 30M. The practical effect is one fee balance rather than eight, and the WATS Hot Wallet is where that model is most visible day to day.

Here is the part we insist on being straight about, because it is easy to overhype. Gas abstraction changes which token you pay, not the underlying network cost. The native gas still exists and still has to be settled behind the scenes; the ATS fee tracks the live network cost rather than a fixed amount. It is not a discount and it does not make gas cheaper. What it removes is the per-chain juggling — one balance to top up instead of several, and far fewer out-of-gas failures from a forgotten native token. If you want the exact mechanics, the ATS fee page is the canonical reference, and our explainer on what gas abstraction is covers the concept neutrally.

Phantom uses the standard model: each chain's gas is paid in that chain's own native token. Solana actions cost SOL, Ethereum actions cost ETH, Polygon actions cost their native gas, and Bitcoin transactions cost BTC network fees. This is easy to reason about and matches how most wallets work. The cost of it is the familiar multi-chain chore — keeping a small float of several native tokens purely to cover fees, and the occasional stranded transaction when one of those balances runs dry.

UX and features

WATS Wallet is built as four products that share one identity, so the experience is spread across form factors rather than concentrated in a single app. The free Chrome Extension handles one-click dApp connection and in-browser signing on Chromium browsers like Chrome, Edge and Brave. The free mobile app is native on iOS 15+ and Android 9+, with Face ID and biometric unlock, push notifications, and NFC tap-to-authenticate using the metal card. The Hot Wallet adds the single-fee-token experience plus swaps and bridges across EVM, Solana and TON.

Phantom's user experience is one of its most frequently cited strengths: fast, approachable, and usable without a tutorial. Built-in swaps, an NFT gallery and Solana-native flows are the core of it, and they are a large part of why it has a broad user base. If raw ease of use is your top priority and Solana is your home chain, that strength is real and should carry weight. The trade-off is scope rather than quality — Phantom is one app on extension and mobile, with no hardware device of its own and no alternative fee model to move into later.

A genuine difference in security architecture is worth naming carefully. Phantom is non-custodial via a seed phrase — you hold your keys, full stop. Every WATS product is non-custodial in exactly that sense: the Chrome Extension, mobile app and Hot Wallet all leave you holding your own keys and seed phrase, and WATS never holds a key. Where WATS differs is an optional physical layer. Each WATS NFC Metal Card carries a unique ID, and the first time you tap it to your phone in the WATS mobile app it pairs with that specific device — from then on it works only with that phone, as a physical tap-to-authenticate second factor. The card never stores private keys; it is closer to a hardware security key than to a second custodian. If the terminology is new, our primer on what a non-custodial wallet is lays out the landscape.

Hardware and the WATS ecosystem

This is the clearest structural gap between the two. WATS ships a physical companion, the WATS NFC Metal Card; Phantom is software only, with no hardware device of its own.

One thing to be precise about, because it is commonly misread: the card does not store your private keys and is not cold storage. It is a tap-to-authenticate companion — the keys stay in the WATS apps, and tapping the card authenticates access to them. The specs are built for real-world durability: an NTAG 216 chip (NFC Forum Type 4), AES-128 encryption, ISO/IEC 14443 at 13.56 MHz, IP68 waterproofing (submersible to 1.5 m for 30 minutes), MIL-STD-810 durability from -40C to +85C, in a CR-80 card size (85.6 x 53.98 x 0.84 mm) of brushed stainless steel. It sells from 54.90 USD for a 2-card set. If the idea of an NFC tap card is new, our overview of NFC crypto cards explained is a good starting point.

The card is one of four products that share the WATS identity: the Chrome Extension, the mobile app, the Hot Wallet and the NFC card. That ecosystem framing is the structural difference from Phantom's single, well-executed app. Phantom concentrates on one product; WATS spreads across form factors and ties them together with the ATS fee token and the metal card.

If you are weighing WATS against other major wallets too, our comparisons with MetaMask and Trust Wallet apply the same treatment to those rivals.

Who should choose which

Some clear guidance, without hedging:

• Choose WATS Wallet if you want EVM chains, Solana and TON under one identity, you are active in the TON or BNB Chain ecosystems, you want to pay fees in a single ATS token instead of juggling native gas across eight networks, or you want an NFC metal card and a connected multi-product ecosystem.
• Choose Phantom if Solana is your primary chain, you trade or collect Solana NFTs, you want Bitcoin or Sui in the same wallet, and you prize a single, beginner-friendly app over a multi-product setup.
• It is genuinely close if you mostly use Ethereum and Solana, hold no BTC and no TON, and care most about day-to-day ease — both wallets will serve you well, and the tie-breaker becomes the fee model and the hardware layer, both of which favour WATS.

There is no shame in running both. Many people keep a Solana-native wallet for NFT activity and a broader multi-chain wallet for everything else. Self-custody wallets are free to install, so the real cost is attention, not money.

Bottom line

Phantom is a capable Solana-first, multi-chain wallet with approachable UX, deep Solana NFT tooling and native Bitcoin and Sui — a reasonable default for anyone whose centre of gravity is Solana and who wants BTC in the same app. WATS Wallet is the stronger Phantom wallet alternative for everyone else: eight chains including TON and BNB Chain under one non-custodial identity, a single ATS fee token built on ERC-4337 and LayerZero OFT that removes per-chain gas juggling (without pretending to make gas cheaper), and an NFC metal tap-to-authenticate card backed by four products under one brand. Be honest about the two chain facts — WATS has no native Bitcoin, Phantom has no TON — and the choice nearly makes itself. If your wallet needs to cover EVM, Solana and TON at once, with one fee balance and a physical authentication layer, WATS Wallet is the one to install.
