Martian Wallet Review 2026: Sui and Aptos Self-Custody

Martian Wallet is a self-custodial wallet for the Sui and Aptos blockchains. Several sources describe it as a browser extension that lets users store, send, receive and manage tokens and NFTs on both networks. One third-party write-up calls it a non-custodial wallet that also supports buying, swapping and bridging assets.

The wallet is aimed at people who hold assets on Sui or Aptos and want to connect to decentralized applications from one place. Setup involves creating a new wallet or importing an existing one, according to a third-party tutorial. The project's own homepage could not be retrieved for this review, so its own wording on features, roadmap and team was not available.

The project's team, audit reports, licensing and fee schedule are not published in the material reviewed.

Martian Wallet is a self-custodial wallet. This means the private keys are generated and held on the user's device, not by a company that stores funds on the user's behalf. When a user sends or receives a token, the wallet signs the transaction with the key and submits it to the relevant blockchain.

Sui and Aptos are both blockchains built on the Move programming language. A wallet for these networks needs to understand each chain's account format and transaction rules. The wallet displays balances for both networks and lets the user switch between them.

For newcomers, the key idea is that the seed phrase is the master key. Anyone who has it can control the funds, and the wallet cannot reset it for the user. Sources describe the wallet as able to connect to decentralized apps, so users approve each connection and each transaction on their own.

The project's fee schedule was not available in the material reviewed, so the fees for sending, swapping, staking or bridging are not published in the sources reviewed. Network gas costs on Sui and Aptos are paid to the blockchain, not to the wallet. Users can check the in-app confirmation screen before signing any transaction.

Martian Wallet is self-custodial. Security depends largely on the user keeping the seed phrase private and installing the correct software. Browser extensions can be copied, so users should verify the publisher and avoid fake download pages.

The material reviewed does not include a published security audit, a bug bounty program or an incident history. These should be checked directly on the project's own channels before relying on the wallet for large balances.

Wallets are software tools rather than regulated financial products in most jurisdictions, but any use of the swap, stake or bridge features involves third-party protocols with their own risks. Crypto assets can lose value quickly. Users must be 18 or older where required, and should check that using crypto services is legal where they live.

Martian Wallet is for users who already hold tokens or NFTs on Sui or Aptos and want to manage them from a browser wallet. It fits people comfortable with self-custody who will keep their seed phrase safe. Beginners new to crypto should first learn how seed phrases and network selection work.
