the underlying cryptography guarantees integrity and non-repudiation, meaning signatures can’t be forged and every action is verifiable on-chain. Combined with optional integrations like multi-signature schemes or hardware wallets, these mechanisms provide both strong asset security and

On Sui, your wallet assets are protected by strong cryptography built into the protocol. Each wallet is tied to a public/private key pair, and transactions are only valid if they’re signed with the correct private key. By default, Sui supports Ed25519 and Secp256k1 signatures, which are widely used in blockchain systems for secure, efficient verification. The public key generates your wallet address, while the private key never leaves your device, meaning no one else can authorize movements of your assets. On top of that, Sui uses object ownership rules enforced by Move, so even if someone tries to tamper with storage, assets can’t be duplicated or transferred without the right authorization. For extra flexibility, you can also use multi-signature accounts or key rotation, which help manage security over time and across multiple devices. Together, cryptographic signatures and Move’s ownership model ensure that your wallet and assets are both tamper-proof and safe from unauthorized transfers.
