PREPARING FOR MAINNET LAUNCH ON BASE

The bank for AI agents.

A yield vault for stablecoins, with rules anyone can verify on-chain. Two specialised agents handle the research and the risk scoring.

01 / Inside Fortress

Two agents propose.
The envelope decides.

Most vaults give a single agent the keys. Fortress splits the work between two specialised research agents and a small piece of code that actually moves capital. The agents only propose. The code follows the rules, every time, in plain sight.

THE ENVELOPEEverything happens here.
ON-CHAIN RULES

A small contract that wraps both agents below. They propose. It decides. Every move has to fit inside the caps. Anything else is rejected, in public, on-chain.

02 / The yield universe

Nine pillars.
Caps you can verify on-chain.

Capital flows into nine yield pillars on Base, with each pillar capped at a fixed percentage of vault TVL. The caps are enforced in Solidity, not in policy. Changing them requires a 3-of-5 multisig and a 7-day timelock that any depositor can watch.

PRIMARY CAPS SUPPORTING CAPS
  • Lend stablecoins into deep, shared markets and earn what borrowers pay.

    • Morpho
      Base

      The dominant curated-lending venue on Base. Vaults run by named risk teams like Gauntlet and Steakhouse.

    • Aave v4
      Base

      The largest lending market in DeFi. Hub-and-spoke architecture sized for institutional flows.

    • Compound III
      Base

      Single-collateral USDC market. Conservative rates, deep liquidity, long track record.

  • ETH that secures one network secures another. Stable, watched closely.

    • EigenLayer
      Ethereum, Base

      The largest restaking protocol. Monitored continuously for cascade risk after the April 2026 oracle event.

    • Symbiotic
      Ethereum

      Permissionless restaking with collateral isolation per service. Smaller, newer, scored independently.

  • Lock in a known yield to a known date instead of riding a floating rate.

    • Pendle
      Base

      The dominant fixed-rate primitive. Roughly 98% of yield-tokenisation TVL lives here.

  • Tokenised short-duration credit. Yield from off-chain assets, settled on-chain.

    • Ondo
      Base

      Tokenised US Treasuries and short-duration credit. The reference RWA for institutional flows.

    • Centrifuge
      Base

      Tokenised private credit. Selected pools with audited underwriting only.

  • Restaking with a liquid wrapper. Smaller cap reflects sequencing risk.

    • ether.fi
      Base

      Liquid restaking via weETH. Capped at 5% so a depeg never threatens the vault.

  • Stablecoin trading venues. Quiet, deep yield from real swap volume.

    • Curve
      Base

      The original stablecoin AMM. Used for the deepest USDC pairs only.

    • Aerodrome
      Base

      Base's home DEX. Bonus emissions on top of trading fees.

  • Take the other side of leveraged trades and earn the fees they pay.

    • Hyperliquid HLP
      Hyperliquid

      The reference perp DEX vault. Profitable in 24 of the last 26 months. Accessed via tokenised wrappers.

  • Direct reward programs run by Base and Arbitrum on selected positions.

    • Base incentives
      Base

      Selected emission programs that pay on top of native protocol yield.

    • Arbitrum STIP
      Arbitrum (CCTP spoke)

      Reward programs accessed through the Arbitrum spoke. Cap-limited to keep cross-chain exposure small.

  • Selective allocation to new protocols once Sentinel scoring clears them.

    • Selective new venues
      Base

      Allocated case by case after Sentinel scoring, audit review, and a minimum operating history.

Fast within bounds.
Slow at the edges.

A bank's prudence with an agent's API. Built for autonomous agents on Base, open to human depositors too.
