For Developers - RNDRNTWRK

RNDRNTWRK gives developers the surfaces to build games, payment flows, agents, overlays, and live creator experiences on top of one active system. If your application needs to verify participation, react to live events, or move value across the network, this is where you build it.

What You Can Build

Games that verify player activity and settle rewards in USDC
Payment flows that combine verification, routing, and programmable payment links
Cross-chain USDC movement through sw4p across supported chains
Interactive stream surfaces, overlays, and live participation modules
Bots, agents, and automations that react to REST and live SSE events

Choose Your Starting Point

Build a game

Use GameHarness and VAP to integrate verified gameplay, scoring, and reward accrual.

Build payment flows

Use AGG, Hyperlink, and sw4p to route and move value.

Build bots and automations

Use the REST API and SSE stream to react to live system events.

Build on-chain

Use the Solana / Anchor program layer for rewards, escrow, and lottery logic.

API Overview

Most integrations start the same way: authenticate with SIWS, keep the session cookie, use REST for actions, and SSE for live state. Base URL: https://api.rndrntwrk.com Authentication: SIWS (Sign In With Solana):

POST /auth/nonce, request a sign-in nonce
Sign the nonce with a Solana wallet
POST /auth/verify, submit signed message, receive session cookie
Include the session cookie on all subsequent requests

Format: JSON REST for requests and responses. SSE for real-time events. Endpoint groups:

Group	What It Covers
Authentication	Nonce, verify, logout, social linking
Arcade and Gaming	Score submission, game state, per-game leaderboards, stats
Battles	Create, join, and track PvP matches
Lottery	Create rounds, buy tickets, finalize draws, audit trails
Leaderboards	Global, per-game, quest, and referral rankings
Rewards	Claim USDC, Merkle proofs, epoch management, projected earnings
Referrals	Generate links, bind codes, track performance
Profile and Tasks	User profile, daily tasks, payment history
Events and SSE	Real-time event stream, burn events
Quests	List quests, track progress, check multipliers
Social	Twitter webhook, social sharing data
Clips	Upload and list gameplay clips
Eligibility and Config	Token-gate checks, normalization config, game registry

Integrate a Game

GameHarness is the fastest path for integrating a game into RNDRNTWRK. Your game is responsible for:

Gameplay logic
Event emission
Score-producing actions

The harness is responsible for:

Session lifecycle
VAP connection
Hashing and signing flow
Verifier submission
Reward accrual hooks based on normalization settings

<GameHarness appId="your-game-id" onSessionStart={handleStart}>
  <YourGameComponent />
</GameHarness>

The harness manages the full VAP lifecycle: connect, play, hash, sign, transmit. Your game emits events (SCORE_UPDATE, ENEMY_KILL, etc.) and the harness aggregates them into a Merkle root. The session key signs the root and the signed payload is sent to the VAP Verifier. Score normalization maps all games to a 0 to 10,000 scale. Normalization config is managed at the protocol level. See Arcade Overview for the current normalization rules and scoring model.

Verification, Routing, and Settlement

Four components handle verification, routing, and settlement across the network. Each has a distinct role.

VAP: Verifiable Attention Protocol

VAP verifies participation.

Ed25519 challenge-response sessions
WebSocket heartbeat at 5-second intervals
Session lifecycle: connect, challenge, sign, verify, accumulate

Status: VAP v1 is live. VAP v2 is in design (not yet deployed). See VAP and VAP v2.

AGG: Payment Aggregator

AGG routes and settles supported payment flows inside the protocol.

Solana-native settlement via Jupiter (live)
HTTP 402 (Payment Required) standard support

Status: Solana-native settlement is live. Cross-chain routing via the sw4p engine is in development. See AGG.

Hyperlink: Smart Payment Links

Hyperlink creates programmable payment surfaces.

Generate payment links programmatically
Embedded wallets, analytics, and social attribution
See Hyperlink

sw4p: Cross-Chain USDC Movement

sw4p is the dedicated cross-chain USDC movement surface. Use sw4p when your application needs USDC to move between supported chains without wrapped assets or liquidity-pool dependencies.

Burn: USDC is burned on the source chain
Attest: the engine observes and verifies the burn attestation
Mint: Native USDC is minted on the destination chain

SDKs:

TypeScript: @sw4p/sdk (docs.sw4p.io)
Rust: @sw4p/rs-sdk (docs.sw4p.io)
Full docs: sw4p Documentation Site

Real-Time Events (SSE)

Use SSE when your application needs live state without polling. Subscribe to GET /events for a persistent SSE connection. Authentication follows the same SIWS session model as the REST API. Event categories:

Category	Examples
Gameplay	`new_entry`, score updates, game state changes
Chat	`chat_message`, moderation events
Round state	Round transitions, winner announcements
Rewards	Claim events, epoch transitions
System	Burn events, system notifications

Format: text/event-stream with typed JSON payloads. Reconnection should be handled client-side. Events are delivered in order within each category.

Protocol Programs and Settlement Logic (Solana / Anchor)

The protocol includes Anchor-based Solana programs that handle on-chain settlement and reward distribution.

Rewards program: commit_epoch → fund_vault → claim_reward pipeline
Merkle-tree distribution for provable USDC payouts
PDA-based escrow for tournament prizes and lottery pools
On-chain randomness via Switchboard VRF for lottery draws

These programs handle the on-chain logic beneath the higher-level application surfaces. Most developers will interact with the REST API and SSE rather than calling these programs directly.
