In the fast-paced world of Solana, where meme tokens launch and trade at lightning speed, having a reliable wallet is crucial. But what if that wallet isn't fully open source? That's the question sparking debate in a recent Twitter thread started by developer Amir Bani, who tweeted: "Open source wallet on Solana. Anyone? Sollet you there? @aeyakovenko the theory that at some point open source catches up is not holding up here."

For those new to the term, open source means the software's code is publicly available, allowing anyone to inspect, modify, and improve it. This transparency is key in crypto, where trust and security are paramount—especially when dealing with volatile meme tokens on Solana, a high-speed blockchain known for its low fees and scalability.

Amir's tweet, posted on September 9, 2025, tags Anatoly Yakovenko, Solana's co-founder, highlighting a perceived gap: despite Solana's open-source ethos, dominant wallets like Phantom aren't fully open. Phantom, while popular for its user-friendly interface, has faced criticism for not being completely transparent with its code.

The thread quickly drew responses from the community, showcasing potential alternatives:

• Backpack: Mentioned by Mike (@heymike777), Backpack isn't under the permissive MIT license but makes its source code available. It's a solid option for Solana users, integrating well with dApps and meme token platforms. Check it out on Backpack's site.

• Unruggable: Adam (@adhcrypto) shouted out Unruggable, a fully open-source hardware wallet native to Solana. Amir expressed excitement, asking if its UI could stand alone without hardware. This project emphasizes self-custody, vital for protecting meme token holdings from rugs or hacks. Learn more at Unruggable's GitHub.

• Darklake's Android Wallet: Vitor (@pyvitor) shared a GitHub link to an in-development Android wallet, promising an iOS version soon. This grassroots effort could democratize access for mobile users trading memes on the go.

• Metamask on Solana: Gui Bibeau (@GuiBibeau) noted Metamask's support for Solana, but Amir corrected that its license isn't truly open source. Still, it's a familiar choice for multi-chain users dipping into Solana memes.

Other replies included Cloakd (@CloakdDev) recalling past attempts thwarted by favoritism toward Phantom, and Beeman (@beeman_nl) sharing a proof-of-concept developer wallet that's open for collaboration.

This discussion underscores a broader point: in the meme token space, where projects like Pump.fun on Solana enable instant launches, open-source tools foster innovation and trust. Closed or semi-closed wallets might limit community contributions, slowing down features tailored for meme trading, such as faster swaps or better blink integrations.

If you're a blockchain practitioner or meme token hunter, keeping an eye on these open-source initiatives could give you an edge. Projects like these not only enhance security but also align with Solana's decentralized spirit. What do you think—time for a fully open wallet to take the throne?
