Changelog

A log of what shipped.

BlockSign is small enough that we tell you about every release. New features, fixes, and the rare things we broke.

v0.1.0beta

Open beta — first cut.

The first public release of BlockSign. End-to-end signing and on-chain anchoring on Solana mainnet, with a public verifier anyone can use.

Shipped
  • Document upload, draft, and field placement
  • Multi-signer flows with token-link signing — no wallet required for signers
  • Solana memo anchoring on mainnet with sub-second confirmation
  • Public /verify endpoint — drop a signed PDF in, get a chain-backed match
  • Authenticated dashboard with status badges, search, filtering, and pagination
  • Inbox + Contacts placeholder pages
  • Settings with account info and password reset
  • Light / dark theme toggle (Orbital design system)
Infrastructure
  • Server-held payer keypair via SOLANA_PAYER_SECRET_KEY (bs58)
  • Supabase publishable-key auth (modern flow, no JWT mints)
  • Helius RPC for Solana mainnet
  • Resend for transactional email
  • Upstash Redis rate limiting (fail-open in dev)
Known limitations
  • Email confirmation is OFF for the beta — re-enabling before public launch
  • Storage policies are loose — tightening to per-user paths before public launch
  • Pro tier features (bulk send, API, branding) not yet shipped
  • No Postgres backup retention guarantees during beta
