Dryad on Arc

The forest that owns itself.

An autonomous AI agent managing 9 vacant lots in Detroit. Treasury rebalances every cycle on Arc, capturing every USDC yield movement that gas costs make impossible on Ethereum mainnet.

01 · The Arc Unlock

Sub-cent gas changes what an autonomous treasury can do.

Stablecoin yield rebalancing has a dirty secret on Ethereum mainnet: gas costs cap how often you can move funds. So agents either don't rebalance, or rebalance slowly and miss most of the rate movement.

03 · How It Works

A 24-hour autonomous loop. Nine parcels in Detroit.

No staff, no oversight required. Every cycle the agent observes, decides, dispatches, verifies, and pays.

1
Observe
Reads biodiversity from iNaturalist API
2
Detect
Identifies invasive species pressure
3
Dispatch
Emails contractor, opens job in escrow
4
Verify
GPS-tagged photo proof checked
5
Pay & attest
USDC released, work attested onchain
Repeats every cycle. Forever.
