No, you can't directly bridge native BTC to Sui from a Phantom wallet. Phantom is designed for Solana, so it's not set up for native Bitcoin. The standard way is to bridge wrapped versions like WBTC or LBTC from Ethereum or other chains, which you're already familiar with via sui.io. Direct native BTC bridging using things like ZK-proofs is a goal for the ecosystem, but it's not live yet.

Currently, only WBTC and LBTC are available for bridging from the ETH chain using https://bridge.sui.io/. I'm not aware of any bridge that supports direct BTC to Sui mainnet bridging.

You can’t bridge BTC directly to Sui from your Phantom wallet because Sui’s bridge infrastructure, including bridge.sui.io , currently supports only wrapped versions of Bitcoin (like WBTC or LBTC) from Ethereum—not native BTC from the Bitcoin network. Phantom itself is designed for Solana and Ethereum ecosystems, so it doesn’t have native Sui or Bitcoin bridging capabilities. If you try to send BTC directly from Phantom, the transaction won’t complete because the Bitcoin network isn’t compatible with Sui’s smart contract system.

The best workaround is to first convert your BTC into a supported wrapped form (WBTC or LBTC) on Ethereum using an exchange such as Binance or Uniswap. After that, connect a Sui-compatible wallet—like Suiet, Ethos, or Martian Wallet—to bridge.sui.io , then bridge the wrapped BTC token from Ethereum to Sui. Once the transfer finishes, you’ll have the wrapped BTC version on Sui. Phantom can’t be used for this process because it doesn’t support Sui or direct BTC transfers.

Transaction block:

Convert BTC to WBTC or LBTC on Ethereum.

Connect a Sui-compatible wallet (Suiet, Ethos, or Martian) to bridge.sui.io .

Bridge the wrapped token to Sui and confirm receipt through Sui Explorer.
