Syenite

The DeFi interface for AI agents. One MCP endpoint for swaps, bridges, yield, lending, and risk across 30+ chains.

What This Is

Syenite is an MCP server that gives AI agents everything they need to interact with DeFi — swap routing, cross-chain bridges, yield intelligence, lending rates, risk assessment, and position monitoring. Intelligence and execution in one place (not swap-only).

Agents read data, get quotes, and receive unsigned transactions ready to sign. Syenite never holds private keys — no custody, no API key required, rate-limited for production use.

Quick Start

{
  "mcpServers": {
    "syenite": {
      "url": "https://syenite.ai/mcp"
    }
  }
}

No API key needed. 30 requests/minute per IP.

Tools

Swap & Bridge

Tool	Description

swap.status	Track cross-chain bridge execution status

Yield Intelligence

Tool	Description
yield.opportunities	Best yields across lending supply, liquid staking, vaults, savings rates, and basis capture
yield.assess	Deep risk assessment for any yield strategy

Lending

Tool	Description
lending.rates.query	Borrow/supply rates across Aave v3, Morpho Blue, Spark
lending.market.overview	Aggregate market view — TVL, utilization, rate ranges
lending.position.monitor	Health factor, liquidation distance for any address
lending.risk.assess	Risk assessment for proposed lending positions

Architecture

Agent → syenite.ai/mcp
         ├── swap.quote        → Li.Fi API (1inch, 0x, Paraswap, bridges)
         ├── swap.status       → Li.Fi status tracking
         ├── yield.*           → On-chain data (Aave, Lido, Morpho, Yearn, Ethena, Maker, ...)
         └── lending.*         → On-chain data (Aave v3, Morpho Blue, Spark)

Swap routing via Li.Fi aggregation. Yield and lending data sourced directly from on-chain contracts via Ethereum RPC with Chainlink price feeds.

Yield Sources

• Lending Supply: Aave v3, Morpho Blue, Spark
• Liquid Staking: Lido (stETH/wstETH), Rocket Pool (rETH), Coinbase (cbETH)
• Savings Rate: Maker DSR (sDAI)
• Vaults: MetaMorpho (Steakhouse, Gauntlet), Yearn v3
• Basis Capture: Ethena (sUSDe)

Supported Chains (Swap/Bridge)

Ethereum, Arbitrum, Optimism, Base, Polygon, BSC, Avalanche, zkSync, Linea, Scroll, Gnosis, Fantom, and 20+ more.

How Execution Works

swap.quote returns an unsigned transactionRequest with optimised calldata. The agent or user signs and submits from their own wallet. For cross-chain bridges, swap.status tracks progress. Syenite never holds keys.

Product Tiers

Tier	Who Operates	Who Custodies	Target
LISA	Client signs	Client's custodian	Institutions wanting self-service lending
MLISA	Syenite operates	Client's custodian	Institutions wanting managed lending
ML	Syenite operates	Syenite's custodian	Full-service managed lending

All tiers share the same vault infrastructure (Safe smart accounts + Zodiac Roles).

Distribution Channels

1. MCP DeFi Router — the canonical tool interface for AI agents. Free data drives adoption; execution tools generate revenue via integrator fees on swap/bridge volume. Live at syenite.ai/mcp.
2. AC Smart Accounts — whitelisted adaptor on Threshold institutional UI.
3. Direct Platform — institutions use Syenite vaults directly (LISA/MLISA).
4. B2B Infra — lending desks integrate vault API + risk framework.

Status

MCP server is live at syenite.ai with swap/bridge routing (30+ chains), yield intelligence (10+ protocols), and lending tools (Aave v3, Morpho Blue, Spark). Vault contracts are a parallel build track.
