Online payments and cryptocurrency
We analyze the technical and legal reasons for the irreversibility of crypto translations: how signatures and consensus work, what is finality, when rare exceptions are possible, and how to protect yourself from errors before sending.
Online payments and cryptocurrency
We compare commissions, speed, cross-border transfers, currency spreads, privacy and automation. We give a checklist and schemes where crypto objectively saves money and time, and where banks are still more convenient.
Online payments and cryptocurrency
Practical instructions for secure crypto transfers: network and address selection, memo/tags, test transactions, protection against phishing and "clipboard stylers," work with commissions and stuck payments. Step-by-step checklists and emergency plan.
Online payments and cryptocurrency
We explain why automatic verification and "copy-paste" cannot be trusted: clipboard stylers, QR spoofing, "address poisoning" attack, similar characters and network errors. We give a checklist of manual verification before sending and a protocol of actions in case of doubts.
Online payments and cryptocurrency
What is Memo/Tag/Payment ID, in which networks they are required, why their absence leads to "unidentified" deposits, and how to build an error-free routine. Checklists, typical scenarios and emergency plan.
Online payments and cryptocurrency
Step-by-step guide: where to find a hash (TxID), how to read a blockchain browser, what "pending/confirmed/failed" means, how many confirmations are needed, how to speed up or save a "frozen" payment (RBF/CPFP), and how to deal with memo/tags, tokens and bridges.
Security and storage of cryptocurrencies
We analyze the risks of fake and "forked" applications, attacks through application stores and browser extensions, domain spoofing and harmful SDKs. We give a wallet verification checklist, secure installation sources and a routine of updates without losing keys.
Security and storage of cryptocurrencies
We analyze why to duplicate a seed phrase, what threats it closes, where and how to store copies (paper/metal/encryption), what is an additional password (BIP39 passphrase) and Shamir, how to do "recovery exercises" and prepare inheritance without the risk of leaks.
Security and storage of cryptocurrencies
What is the "backup key" in different wallet models (single-key, multisig, MPC, smart wallets), what risks it saves and how to properly create, store, periodically check and use it during recovery or rotation.
Security and online payments
A complete scheme against phishing: from checking the address and network to secure signatures, whitelists, hardware wallets and revving rights. Checklists, incident protocol and "red flags" on the web, DApp, Telegram/Discord and mail.
Onramp/Offramp and Safety
We analyze the real risks of "anonymous exchanges": blocking and scam, "dirty" coins and sanctions lists, lack of checks for taxes, inflated spreads and hidden commissions, fake couriers and security threats. We give safe alternatives and a checklist on how to minimize damage, if necessary.
Confidentiality and compliance
We analyze how anonymous crypto payments differ from ordinary ones: the risks of online analytics and sanctions, "dirty" UTXO, metadata of devices and bridges, problems with withdrawal to exchanges and banks. We give practical precautions, checklist and emergency plan.
Online payments and cryptocurrency
We show how the blockchain provides "end-to-end" visibility of payments: a public register, unchangeability of records, cryptographic evidence, logs of smart contracts and independent verification. We analyze the benefits for users, business and compliance, as well as restrictions and balance with privacy.
Online casinos and blockchain technologies
We analyze the architecture of on-chain games: deposits and conclusions through a smart contract, generate randomness (commit-reveal/VRF), "provably fair," accounting for bets and payments, bonuses and jackpots, as well as risks: gas, MEV, oracles, upgrades and security. We give checklists for players and operators.
Online casino and DeFi
What does DeFi integrate into online casinos: self-custody, instant deposits/payments, on-chain transparency, tokenized bonuses and cashback, low L2 fees and cross-chain flexibility. We analyze the pros, risks (contracts, bridges, approve), as well as checklists for selection.
