Build the first post-quantum Lightning.
The apps on it have not been written yet. That is the opportunity, and we are giving it to builders first.
Lightning, the instant-payments layer of crypto, was not built for the quantum era. We rebuilt it to be. Now we are inviting a small group of builders to ship the first post-quantum payment apps and own that ground before anyone else.
Why build now
First-mover on real ground. Whoever ships the first PQ Lightning wallet, the first merchant tool, the first streaming-payments app, defines the category.
It is proven. The soq-lightning-sdk ran invoices, channels, HTLCs and a dual watchtower on the pre-mainnet test network, with serializers proven byte-exact against the node. Channels activate on mainnet after a security audit.
Early to the whole ecosystem. A post-quantum Layer 1, a post-quantum stablecoin in USDSOQ, and a bridge, all reaching mainnet this fall. Builders who are in now are in at the start.
Post-quantum Lightning, working. The first apps are yours to write.

What to build first
Starter tracks
01AI & machine-to-machine payments — agents paying per call, API monetization, IoT, pay-on-delivery. The frontier. See SOQ-402 running live.
02Creator & content monetization — tipping, payouts, pay-per-view, streaming subscriptions.
03Games & virtual economies — in-game payments, micro-rewards, signed asset ownership.
04Commerce & point-of-sale — merchant tools, remittance, instant settlement.
05Settlement & record-anchoring — PQ-signed documents and IDs, healthcare and supply-chain proofs (data off-chain).
06Wallets & infrastructure — the building blocks the ecosystem runs on.
If you want to be early to post-quantum payments, this is the door.
