DEVNET ENVIRONMENT

Connect & Build

Add the Taifoon Devnet to your wallet, request test FOON tokens from the faucet, and start deploying against live infrastructure.

FOON FAUCET

Request devnet FOON tokens to test staking, proof verification, and taifoon-sdk contract interactions. Rate limit: 1 request per 24 hours.

Contract Addresses

All contracts are deployed on Arbitrum Sepolia and Solana Devnet. Mainnet addresses will be published after completion of security audits.

Light Clients16 deployed

Each supported chain has a dedicated light client that validates block headers and finality proofs natively. The V5 proof system combines all chain proofs into a single SuperRoot — one hash that anchors the state of 41 chains simultaneously.

INTEGRATION PATHS

Choose Your Depth

PROOF CONSUMPTION

Read & Verify

Fetch V5 proofs via REST API and verify on-chain with ~20 lines of Solidity. No infrastructure to run.

SUITED FOR
DeFi protocols, bridges, oracle operators, any protocol consuming cross-chain state
SIGNAL INTEGRATION

Stream & React

gRPC streaming, WebSocket signals, event subscriptions. Sub-10ms latency cross-chain data in your hot path.

SUITED FOR
Trading desks, MEV searchers, indexers, real-time aggregators, any system that needs live cross-chain feeds
GRID OPERATOR

Run & Earn

Run a Spinner node, submit block headers, participate in the verification network. Full protocol participation with network rewards.

SUITED FOR
Infrastructure providers, L1/L2 teams, node operators, validators — anyone who wants to BE the verification layer

BUILDER SUPPORT

Build With Us

Taifoon is building a verification layer for a multi-chain ecosystem. We provide technical support, infrastructure access, and partner integrations to teams building on our stack.

TECHNICAL SUPPORT

Direct access to core engineering. Weekly office hours with the team that built the V5 proof system. Architecture reviews for your integration.

INFRASTRUCTURE ACCESS

Free Extended tier for qualifying projects. Priority API access, dedicated endpoints, custom chain indexing on request.

PARTNER INTEGRATIONS

Co-development with existing Taifoon partners including bridge protocols, oracle networks, and DeFi primitives already building on the stack.

COMMUNITY & VISIBILITY

Builders channel with 1:1 support. Early feature access. Co-marketing with Taifoon ecosystem. Listed in the partner directory.

HOW TO APPLY

Reach out via the builders channel on Telegram with a description of what you're building and your integration needs. The team reviews applications weekly and responds within 48 hours. No pitch deck required — show us code or a spec.

GET STARTED

Zero to Proof in 4 Minutes

1

Install taifoon-sdk

npm install @taifoon/sdk
2

Fetch a V5 Proof

const res = await fetch( "https://scanner.taifoon.dev/api/v5/proof/blob/1/latest" ); const proof = await res.json();
3

Verify On-Chain

// Solidity — import from taifoon-sdk bool valid = v5ProofVerifier.verifyBlockProof( proof.l1_superroot, proof.l3_superroot_proof, proof.l4_block_proof, chainId ); // ~45k gas
