STACH is tradeable: Uniswap v4 pool STACH/ETH live on Base (initial price 4,000,000 STACH/ETH) — routable through aggregators (LI.FI verified).

An open staking-yield experiment on Base. Live aggregator of staking and lending rates across Base protocols — readable by humans on a dashboard, consumable by AI agents over MCP, payable by machines over x402.

No seed round. No token presale. Just a running, open-source experiment. Concept and plan: docs/PIVOT-2026.md.

The product

Piece	What it does
api/	Base yields aggregator (DefiLlama source, 5-min cache, junk-farm filters) with x402 machine-payment endpoints
agents/	MCP server exposing yields as AI-agent tools + resident-analyst pattern (Claude Agent SDK)
dashboard/	React dashboard: Base Yields table, STACH staking, pools
contracts/	STACH token + flexible/locked staking — audited & hardened (audit), 25 tests
website/	Landing page (static, GitHub-Pages-ready)

Legacy 2021–2023 material (Laravel site, old static site, branding, original docs) is kept under website-laravel/, website-static/, branding/, docs/.

Monetization: machines pay, on-chain, automatically — LIVE

Human endpoints (/yields, /vaults) are free. Machine endpoints (/v1/*) speak the x402 protocol with enforcement on: HTTP 402 + payment requirements → the client signs an EIP-3009 USDC authorization ($0.001/request) → our self-hosted settler verifies the signature and submits it on-chain (no facilitator, no accounts, no API keys). Revenue lands at the admin wallet; api/pay-client.js is a reference paying client.

Real yield: collected USDC is distributed to STACH stakers through RevenueDistributor (verified; merkle epochs reproducible from public state via contracts/scripts/revenue-snapshot.js, 180-day sweep-back).

MCP config

The yields aggregator is an MCP server, published on npm as stakechain-mcp. Add it to any MCP-compatible client:

{
  "mcpServers": {
    "stakechain": { "command": "npx", "args": ["-y", "stakechain-mcp"] }
  }
}

Quickstart

# 1. Yields API
cd api && npm install && npm start            # :4000

# 2. Dashboard
cd dashboard && npm install --legacy-peer-deps
npm start                                     # :3000, reads the API

# 3. Give the data to your AI agent (published on npm, no clone needed)
claude mcp add stakechain -- npx -y stakechain-mcp

# 4. Contracts (test + cheap deploy)
cd contracts && npm install
npx hardhat test                              # 25 tests
npm run deploy:baseSepolia                    # free testnet

STACH token

Deployed at the same address on both networks (verified via Sourcify, exact match):

• Base mainnet: 0x82c5f9901CD9AEE3177053482b79aEA235507166 · Blockscout
• Base Sepolia: 0x82c5f9901CD9AEE3177053482b79aEA235507166

Initial holder / admin: 0x2Ab5A19aabc599C1a24CC0541ECB757b56976661. The dashboard targets mainnet by default; set REACT_APP_CHAIN=baseSepolia for the testnet.

Fixed supply 42M. 3M held by the contract as the staking reward reserve (1M flexible / 2M locked over 360 days), 39M to the admin wallet. The 2022 contract had two critical bugs (recipient-burning transferFrom, unbacked reward minting) — fixed and regression-tested in 2026: docs/AUDIT-2026-10.md.

Future revenue-share to STACH stakers is deliberately not built yet — revenue first, distribution second.

Supply transparency

Every STACH is accounted for (snapshot 2026-10-28, verify on-chain):

Holder	Address	STACH	Share
Treasury / operations (funds future liquidity and the experiment)	0x2Ab5…6661	~38.86M	92.5%
Staking reward reserve (3M) + user stakes, held by the token contract	0x82c5…7166	~3.00M	7.2%
Uniswap v4 STACH/ETH pool	0x4985…2b2b	~134.3k	0.32%
Deployer (deploys contracts, holds no tokens)	0x2974…734F	0	0%
Other holders	—	~11.5k	0.03%

Nothing is vesting-locked yet; a treasury timelock is planned once pool liquidity justifies it and will be linked here when deployed. Scanner flags about holder concentration are accurate — this table is the context behind them.

Honest part

This is an experiment, not "the future of finance". Everything here is MIT-licensed, the audit is public, the data endpoints filter out obvious degen traps (min TVL, APY ceiling, no-IL default). Nothing in this repository is financial advice.
