Multisig Configuration & Backup
Correctly backing up 2-of-3 multisig may require saving the private keys and all three xpubs for recovery with only two keys. Encoding xpubs into BIP39 mnemonics isn't directly supported. Store xpubs and metadata securely; consider GPG encryption or offline password managers for digital copies.
Advanced Hardware Wallet Security
For enhanced security, especially during travel or duress situations, utilize passphrases (hidden wallets) on hardware wallets. Stateless wallets (Coldcard, Jade, Seedsigner) requiring seed entry per session offer protection against physical compromise. Memorizing a 12-word seed is also an option considered by some users.
UTXO Management Tactics
Low fee environments, indicated by a relatively empty mempool, present opportune times to consolidate numerous small UTXOs. This optimizes future transaction efficiency and costs. Be mindful of the privacy implications, as consolidation links previously separate addresses on-chain.
Ethereum Privacy Enhancements Proposed
Vitalik Buterin outlined a roadmap for improving Ethereum privacy, potentially defaulting to private transactions via shielded balances and per-app addresses without core protocol changes. Zero-knowledge proofs (zk-tech) are central to enabling these features and mitigating censorship risks associated with privacy tools.
Coinbase User Agreement Updates
Coinbase updated its US User Agreement (effective post-May 27th). Users waive rights to participate in class/collective actions, agreeing to individual arbitration or small claims court for disputes. The agreement specifies New York courts as the default forum for non-arbitrable issues.
