SeaDrop allowlist minting via OpenSea voucher, with the correct custom-chain slug (Robinhood was querying 'ethereum' -> DropNotFound).
- Pre-warm + pre-sign the voucher during pre-arm so T0 is broadcast-only; never fall back to a doomed public mint when no public stage is live.
- Rate-limit hardening: OpenSea returns limits as HTTP 200 'Too Many Requests' (not 429) -> detected + retried with backoff; voucher calls rotate an API key; a global voucherSem caps the fetch burst.
- Settings: API Keys tab; multi-threaded, streaming, live-count free-key grab over a proxy group.
- Manage Funds: searchable wallet pickers.
- Per-wallet stage-open to minted latency shown on success (e.g. 'minted 2213ms block N').
Auto-update: the app downloads the zip asset below and swaps zyper-bot.exe + web/.
