Stocks become
a stable dollar
Deposit tokenized US equities. Mint rUSD against them. Stake to earn protocol revenue. Let autonomous agents handle it — or do it yourself. Built natively on Base.
Numbers, not promises.
Three actions. Full composability.
rUSD — a stable dollar backed 1:1 by tokenized US equities and USDC reserves. Use it like any ERC-20.
srUSD — ERC-4626 vault. Share price grows every block from stability fees. No claim step. No lockup.
Open a vault with bCOIN, bIB01, bCSPX. Mint rUSD up to LTV. Pay stability fee only on what you borrow.
Revenue buys ROOST. Stakers earn it.
Every stability fee, every PSM swap, every liquidation feeds two parallel loops. srUSD stakers earn in rUSD. sROOST stakers earn in ROOST — bought from Aerodrome with protocol revenue. Roost is the first CDP-style protocol with this dual yield loop.
rUSD vs. USDC.
| rUSD · Roost | USDC · Circle | |
|---|---|---|
| Backed by | Tokenized US equities + USDC reserves | Short-dated US Treasuries |
| Issuer | Permissionless smart contracts | Circle (regulated entity) |
| Yield to holder | Auto-compounding via srUSD share price | None — issuer retains the yield |
| Mint mechanism | Open a CDP with any whitelisted bStock | Wire USD to Circle, get USDC |
| Censorship surface | Onchain, no freeze list at protocol level | Circle can freeze any address |
| KYC for end users | None | None on secondary, KYC to mint |
| Composability | Aerodrome, Morpho, Pendle, every EVM DEX | Universal, but yield doesn't follow |
| AI agent integration | MCP server + AgentKit + x402 native | No first-party tooling |
USDC is the most-used stablecoin on Base — and the reserve currency of the Roost PSM. rUSD doesn't replace it; rUSD is what you hold when you want the yield USDC's reserves are already earning.
Four agents. One click each.
We run them. You authorize the spend permission. They keep your position safe without a terminal.
Every Claude touchpoint. Wired in.
Anywhere Anthropic ships, Roost shows up. Same MCP server, different transport.
An MCP server
for the stablecoin economy.
Roost exposes itself as tools to any AI agent. Claude. Cursor. Claude in Chrome. AgentKit-powered bots. 13 tools: get_vault, simulate_position, explain_liquidation, propose_repay, compare_strategies…
Pay-per-call APIs. In USDC.
x402 brings HTTP 402 back from the dead. A premium route returns the price + payment address. Caller attaches a signed USDC receipt, server verifies, content unlocks. 200ms end-to-end on Base.
For agents this is the missing piece — they pay for the data they need without API keys, sign-ups, or human-in-the-loop.

Money has had three phases.
We're building the fourth.
Physical. Anonymous. No yield. Worked because settlement was free.
Digital. Identified. Yield captured by banks. Settlement priced via fees.
Onchain. Permissionless. Yield retained by issuers.
Onchain. Permissionless. Backed by real-world equities. Yield paid to holders. Operated by autonomous agents.
24 vendors. Or 1 contract.
A bank requires custodians, KYC providers, payment rails, ledgers, auditors, compliance teams. Roost replaces all of it with code anyone can read.
The dollar of
the agentic era.
