Kurabase reference

Use database concepts. Keep authority explicit.

Kurabase turns EVM state into a relational developer surface. Tables, policies, migrations, and wallet-bound sessions work without making application developers write Solidity.

Instance: Chain-backed
Authority: Wallet-signed
Gateway: Explicitly delegated

A graphite ledger engraved with interconnected relational tables — Relational state is a first-class chain primitive.

The operating model

A gateway executes an approved plan. It does not become the authority.

Instance owners delegate gateways on-chain. People act through a wallet or configured identity authority. The gateway validates both before it evaluates RLS or submits a write.

See the authorization boundary

Start one local stack

Anvil, delegated gateways, Dashboard, and a fresh instance start from one command.

Run locally

Connect the wallet that acts

The browser signs an EIP-712 session. It never receives a gateway signing key or server secret.

Use tables and migrations

Build against REST or the independent JavaScript SDK with familiar relational primitives.

The application surface

Keep the client familiar.

Use the independent JavaScript SDK for application reads and wallet-authorized writes. Keep instance administration in an owner-controlled flow.

import { createClient } from '@kurabase/js'

const db = createClient(url, publishableKey)
await db.auth.signInWithWallet({ provider: window.ethereum })

const posts = await db
  .from('posts')
  .select('id,title')
  .eq('published', true)
