Prerequisites
- Node.js 20+ and pnpm
- Docker and Docker Compose (for the full three-service stack)
- A TxLINE account with guest JWT access and an activated API token
- A Solana keypair (devnet is sufficient for evaluation — mainnet pricing is supported, but anchoring must stay on the same network as the keypair; see Network Consistency)
1. Install
2. Configure credentials
1
Get a guest JWT
Tissue exchanges TxLINE’s
POST /auth/guest/start for an expiring JWT and renews it
automatically on stream reconnect — you do not need to manage this manually beyond
providing your TxLINE credentials.2
Activate an API token
Run the bundled activation script, which handles TxLINE’s
POST /api/token/activate
response (both the plain-text and JSON response shapes have been observed in
practice):3. Run the full stack
http://localhost:3000
for the dashboard and http://localhost:8788/state for the raw daemon state.
4. Replay a real captured fixture instead of going live
If you don’t have live credentials handy, or want a deterministic run for evaluation, replay one of the real corpora already captured against TxLINE:determinism OK means the same corpus was replayed twice internally and produced an
identical head hash — this is asserted in CI on every build, not just shown here.
