krypco

krypco is a hybrid blockchain: a private permissioned layer anchored to a public chain. This monorepo holds the marketing site, portal, and Phase 5 local hybrid prototype.

Requirements

bun 1.x
Node.js 22 (Next tooling)
Optional: Docker for two local anvil chains

Quick start

bun install
bun run dev          # portal → http://localhost:3000

Hybrid stack (stronger local prototype)

# optional: real local private + public EVM (anvil)
bun run chains:up
# private http://127.0.0.1:8545  public http://127.0.0.1:8546

# terminal A — private sim + explorer API
bun run dev:indexer

# terminal B — posts real public commitment txs when public anvil is up
bun run dev:relayer

# terminal C — portal
bun run dev

Explorer: http://localhost:3000/portal/explorer — source: live when indexer is up
Hybrid status: http://localhost:3000/portal/hybrid — private/public RPC + anchor queue

Without Docker, the indexer still runs a private-layer sim; anchors wait for the relayer until public RPC is available.

Auth & machine keys (Briven)

Secrets live in apps/portal/.env.local (gitignored). Never put m2ms_… or brai_… in NEXT_PUBLIC_*.

Kind	Shape	Where
User auth (browser)	`pk_briven_auth_…`	`NEXT_PUBLIC_BRIVEN_AUTH_KEY`
AI agent	`brai_…`	`BRIVEN_AI_AGENT_KEY` (server)
Machine client (M2M)	`m2m_…` + `m2ms_…`	`BRIVEN_M2M_CLIENT_ID` / `BRIVEN_M2M_CLIENT_SECRET`

Status page: /portal/machine-auth.

OTP / magic email needs a working Briven sender domain before login codes arrive in the inbox.

Wallet

MetaMask (and other injected wallets): wagmi + viem connect.
mavi (always lowercase): krypco’s own wallet — create / import, 24-word backup with 6-blank confirm, encrypted browser vault, balance + send on local anvil, network switcher, activity.
Shared logic: packages/mavi-core. Portal UI: http://localhost:3000/portal/mavi
- Create · Import · Send · Receive · Activity under /portal/mavi/*
- Browser extension with real keys: apps/mavi-extension (create/import/unlock vault). Load unpacked after bun run --cwd apps/mavi-extension build. Pack: bun run ext:pack
  Secrets never leave the browser unencrypted; not a fork of MEW.

Scripts

bun run dev            # portal
bun run dev:indexer
bun run dev:relayer
bun run build
bun run typecheck
