The New England exit off the North American on-ramp.

A sub-regional Authority certified by NorthAmerica. The first 3-deep Authority chain in the DPYC ecosystem (Prime → NorthAmerica → NewEngland); operators serving New England patrons may choose NE to keep certification latency and audit trails as local as the protocol allows.
The metaphors in this project are drawn with admiration from The Phantom Tollbooth by Norton Juster, illustrated by Jules Feiffer (1961). We just built the payment infrastructure.
Architecture
This repository is a thin consumer of the tollbooth-dpyc wheel's tollbooth.authority extension (wheel ≥ 0.22.1). The entire deployable surface lives in src/tollbooth_authority/server.py (~90 lines): a FastMCP instance, an OperatorRuntime, and two register_*_tools(mcp, runtime) calls. Onboarding state machine, Schnorr signer, replay tracker, Neon tenant provisioning, and the Authority @tool definitions are wheel-resident and shared with every other Authority MCP in the ecosystem.
NE was scaffolded from tollbooth-authority at the start (May 16, 2026) but is no longer a fork — wheel v0.22.0 collapsed every shared module into tollbooth.authority.*. The two repos now coexist as independent thin consumers of the same mixin, distinct only in identity, region, and Neon tenant.
For protocol semantics, certificate format, fee cascade, and tool catalog, see the canonical tollbooth-authority README.
Onboarding chain note
NE's onboarding (confirm_authority_claim → check_authority_approval) escalates to NorthAmerica, not Prime — the wheel's resolve_my_parent_npub reads NE's own upstream_authority_npub from the dpyc-community registry and routes the approval DM there. The 3-deep chain is transparent to the protocol; the registry is the source of truth.
Deploy
Two secrets required by Horizon:
| Env var | Value |
|---|---|
TOLLBOOTH_NOSTR_OPERATOR_NSEC | NE's nsec |
NEON_DATABASE_URL | A pooled Neon connection string in aws-us-east-2 |
Everything else — BTCPay credentials for the cashier — arrives via Secure Courier post-deploy (see docs/how-to-add-authority.md in the community repo).
DPYC Ecosystem
NE is one Authority in the wider DPYC federation — a Social Contract of Operators and Authorities bound by transparent, auditable economic rules, with a Certification Chain cascading from the First Curator down through regional Authorities like this one.
