The same recovery phrase produces different addresses under different paths, passphrases and account indexes. How to find where your coins are, and why an SSP seed alone shows an empty wallet.
The last word of a BIP-39 phrase carries a SHA-256 checksum that catches most typos. How it works, why you should never make up your own phrase, and why seed checksum websites are dangerous.
UTXOs are spent whole, so most payments send part of the money back to you as change. Why explorers make it look like you sent more, why wallets use change addresses, the classic lost-change trap, and what SSP does.
A wrong-number text, weeks of friendship, then a trading app with fake profits and fees to withdraw. How romance and pig-butchering scams work, the red flags, how to help a family member, and what multisig can't stop.
EIP-2612 permits and Uniswap Permit2 grant token allowances with a gas-free signature, which is why drainers love them. Which fields to read, why typed-data "sign in" requests are suspicious, how to revoke, and how SSP shows typed data.
Checksums prove you have the same file, signatures prove who published it, and reproducible builds prove it came from the published code. What each one shows, and step by step how to verify an SSP Wallet release.
Couples, parents and families can self-custody together — if they decide who holds what. Three questions to answer first, common household setups, planning for absences, holding for children, and where SSP fits.
Crypto loans let you borrow without selling, but your collateral can be sold for you. How over-collateralised loans and liquidation work, why liquidations cascade, DeFi vs centralised lenders, and how to borrow more safely.
A backup you've never tested is a hope, not a plan. How backups fail, three safe ways to test a recovery phrase, how often to check, and how SSP Wallet and SSP Key build backup checks in.
Smart contracts can't look anything up, so oracles bring prices and events on-chain — and every protocol inherits their weaknesses. How oracles work, how price feeds get manipulated, and what to check before you trust one.
Blockchains upgrade without a central server, through soft forks that tighten the rules and hard forks that change them. How each works, when forks split a coin in two, and what upgrades mean for your wallet.
Scammers take over trusted social accounts to post fake airdrops, migrations and security alerts. How takeovers happen, what the scam posts look like, how to spot them, and how account owners can protect themselves.
A crypto treasury held by one person is one mistake away from a loss. Five questions every team's treasury policy should answer, a starting template, and how SSP Enterprise maps to each of them.
In self-custody your records are yours to keep. What to record for each transaction, a simple routine for exchanges and wallets, verifying with the blockchain, exporting from SSP, and keeping records safe.
A dApp's contracts can be safe while its website is hijacked through DNS, hosting or a compromised dependency. How front-end attacks work, what they ask you to sign, and why your wallet's request screen is the real defence.
Every proof-of-work coin decides in its rules how new coins are created. How Bitcoin's halving works, how Litecoin, Dogecoin, Kaspa and Ethereum differ, and what halvings do and don't mean for holders.
