Gem Wallet shipped WalletConnect support for Sui in version 2.100, released on July 9, 2026 - the network’s ecosystem now opens straight from the app. Cetus, Bluefin, NAVI Protocol, and dozens of other DApps, in a couple of taps, privately and securely.
What Is the Sui Blockchain?
Sui is a Layer 1 blockchain with a market cap of around $2.8 billion. Its ecosystem holds about $420 million in DeFi protocols and another $429 million in stablecoins, and it turns over $169 million in DEX volume and $237 million in perpetuals every week. Transactions finalize in under a second and fees stay at a fraction of a cent, which is why more than 150,000 addresses stay active on the network every day. Our guide to the Sui blockchain covers the network in detail.
WalletConnect removes the last barrier between our users and that ecosystem: everything that used to need a browser extension or a second wallet now happens straight from Gem Wallet. Staking SUI for rewards, swapping, providing liquidity, borrowing against collateral, opening a leveraged position - and your keys stay yours the whole time.
Top Sui DApps to Use With Gem Wallet
Direct access to Sui DApps means new possibilities for our users:
- Cetus: The largest DEX and swap router on Sui - $593 million routed through its aggregator over 30 days, plus $291 million traded in its own pools. Trade SUI, USDC, and ecosystem tokens, or deposit a pair you already hold into a pool and collect trading fees.
- Bluefin: The busiest trading venue on the network - $364 million in spot volume and $126 million in perpetuals over 30 days. Trade at order-book prices or open a leveraged position on SUI, all through the same connection.
- NAVI Protocol: The largest lending market on Sui, with $128 million locked. Put the USDC or USDT sitting idle in your wallet to work at market rates, or borrow against your SUI instead of selling it.
- Haedal: The leading liquid staking protocol on Sui, with $26 million staked through it. Turn SUI into haSUI, keep earning staking rewards, and use the same tokens in pools and lending markets at the same time.
Every other Sui DApp that shows a WalletConnect QR code works too: with Gem Wallet you connect to any of them instantly, in a couple of taps, on iOS or Android.
How to Connect Gem Wallet to a Sui DApp via WalletConnect
- Open the DApp in your browser (for example, Cetus) and tap “Connect”
- Choose WalletConnect, then find Gem Wallet in the wallet list or scan the QR code
- Check the DApp name and website URL on the confirmation screen
- Tap Confirm - the connection is live and your balances sync instantly
Benefits for Gem Wallet Users With Sui WalletConnect
Gem Wallet is a fully open-source, self-custody wallet for Sui and 100+ other blockchains. Here is what you get when you connect to Sui DApps over WalletConnect:
- Full Self-Custody: Your private keys stay on your device and every signature happens locally. A DApp receives the result of a transaction, never access to your funds.
- 100% Open-Source Code: Gem Wallet’s source code is public and passed an independent CertiK audit in April 2026 - anyone can check how Sui transactions are built and signed.
- Privacy With No Sign-Up: Gem Wallet does not collect your data - no email, no phone number, no ID.
- Phishing Protection on the Confirmation Screen: Before you sign, you see the wallet, the DApp name, and its exact website URL. A cloned site gives itself away before the transaction, not after.
- Clean, Simple Interface: Connecting takes a couple of taps - no network to add by hand, no settings to dig through.
- WalletConnect Session Management: Every active connection lives under Settings → WalletConnect, and you can drop any of them in a tap.
- Transaction Simulation Before You Sign: You see which tokens leave your wallet and which arrive before you confirm anything.
- Built-in DEX Aggregator: You can swap USDT, ETH, or BTC for SUI through Mayan, NEAR Intents, and other protocols at the best available rate, without leaving the app.
- Buy SUI With a Card: Every transaction on the network needs its native token, so you can buy Sui right in Gem Wallet - card, Apple Pay, or Google Pay, in 170+ countries.
Resources for Developers
Beyond Sui, Gem Wallet supports WalletConnect across every EVM network - Ethereum, BNB Chain, Polygon, Arbitrum, and others - plus the non-EVM chains Solana and TRON, and the list keeps growing.
Conclusion
Sui is a network where an onchain action takes less than a second, and now the path to that action takes just as little. Open Gem Wallet, connect to a DApp, and use the Sui ecosystem with no middlemen in between.
