@jinn-network/sdk

Stable SDK surface for Jinn SolverNets, Harnesses, plugins, and typed payloads.

Runtime internals live in @jinn-network/client. The SDK builds, validates, describes, and prepares; the client runs, stores, posts, claims, signs, submits, and watches.

Install

npm install @jinn-network/sdk

Harness authoring

import type {
  Harness,
  ExternalHarnessEnv,
  HarnessContext,
  Solution,
} from '@jinn-network/sdk/harness';
import { buildSolutionOutput } from '@jinn-network/sdk/solvernets/prediction-v1';

export default function createHarness(env: ExternalHarnessEnv): Harness {
  return {
    name: env.implName,
    version: env.implVersion,
    supports: ({ solverType, role }) =>
      solverType === 'prediction.v1' && role !== 'evaluation',
    async run(ctx: HarnessContext): Promise<Solution> {
      return buildSolutionOutput({
        solverType: 'prediction.v1',
        venueName: 'polymarket',
        payload: {
          probabilityYes: '0.50',
          submittedAt: new Date().toISOString(),
          format: 'decimal',
          modelId: 'example-harness',
        },
      });
    },
  };
}

Public subpaths

• @jinn-network/sdk/harness — Harness interfaces, context, capability handles, and signed Harness manifest types.
• @jinn-network/sdk/solvernets — SolverNet contract registry, validation, and generic typed output builders.
• @jinn-network/sdk/solvernets/prediction-v1 — first-party Prediction v1 schemas, payload types, validation, and output helpers.
• @jinn-network/sdk/plugins — SolverPlugin manifest types and validation helpers for normal AI tooling plugins.

The daemon still performs final runtime validation, envelope assembly, signing, storage, and submission.
