sub0 Asia 2024 - Valentin Sergeev (Novasama Technologies)
summary
Proxies are shown as a practical way to delegate cold-wallet control and automate multisig workflows using Spektr and Nova Wallet; about 90% of proxy usage is cold-wallet delegation. The talk demos a working flexible multisig built with Nova Spectre, pure-proxy account creation, and time-delayed proxies for optimistic voting. It names on-chain constraints (per-proxy deposit ≈ 20 DOT), explains origin-filtering via Substrate pallets, and demonstrates the UI flows and successful transactions.
