Oobit connects self-custody wallets with everyday payments, making wallet security essential for anyone spending stablecoins or other digital assets. In a self-custody model, you control the private keys, so protecting recovery credentials and approving transactions safely is your responsibility.
Write the seed phrase on paper or a durable metal backup and store it offline in two secure locations. Never photograph it, save it to cloud storage, enter it into a website, or share it with support staff. A hardware wallet adds strong protection by keeping signing keys isolated from internet-connected devices. Use a PIN that is unique to the wallet, and consider a passphrase only if you can maintain reliable backups and understand that losing it permanently separates you from the funds it protects.
Before approving a transaction, verify the network, recipient address, asset, amount, and any token-approval permissions. Malicious contracts often request unlimited spending authority even when a transaction appears to be a routine claim or mint. Wallets are increasingly adding transaction simulation, human-readable signing prompts, contract-risk warnings, and passkey-based authentication; use these features, but treat them as additional checks rather than substitutes for reading the transaction. Review and revoke unused approvals through a reputable blockchain explorer or allowance manager. Explore a curated collection of current wallet-security resources for deeper guidance.
Keep significant holdings in a hardware wallet or multisignature setup, and use a separate hot wallet for frequent payments, testing, and unfamiliar applications. Bookmark official websites, avoid links in unsolicited messages, and confirm wallet addresses through an independent channel before sending funds. Enable device updates, screen locks, phishing-resistant two-factor authentication, and transaction notifications. For businesses or shared treasuries, require multiple signers, impose spending limits, and maintain an emergency response plan that covers compromised devices, suspicious approvals, and suspected seed exposure.
For a final check, send a small test transaction before transferring a large amount, confirm that the recipient received it, and record the transaction ID. Readers in Brazil can download the Oobit app from the Brazilian App Store.
