Boros funding-rate markets

GET 
/v1/data/boros/markets

Every live Boros market: the fixed (mark / implied) APR against the venue's FLOATING funding APR, best bid/ask, maturity, collateral, open interest, fees and margin parameters. Rates are percent; fee and margin parameters are fractions. Cached 30 s per isolate.

Every row carries termSheet (profile boros.funding-swap@v1): a swap sheet with BOTH sides — which leg each side pays and receives, the fixed rate a taker gets now, the carry vs current funding, margin and liquidation terms, fees on notional, the funding-index oracle, the OI cap and the upgrade authority (a 2-of-3 Safe, no timelock). supply / borrow are absent by design and declared notApplicable in coverage. Prose is templated from those fields.

Boros trades perp funding rates as fixed-vs-floating swaps (Pendle, Arbitrum 42161). A Yield Unit (YU) on a market is the funding one venue pays on one unit of notional until maturity. LONG receives the floating funding and pays the fixed rate it bought at; SHORT pays floating and receives fixed — the side that LOCKS a funding income.

  • Sizes are in the market's COLLATERAL: a USD₮0-margined BTC market sizes in dollars of notional, a WBTC-margined one in BTC. Pass notionalUsd to let the API convert.
  • Margin is one cross account per collateral token: IM = |size| × max(|rate|, floor) × kIM × max(timeToMaturity, 5 days). Liquidation at health ≤ 1.
  • Fees: taker |size| × takerFee × TTM once; settlement settleFee annualised on notional every funding period; ~$1 entrance fee per market. Maker orders pay none.
  • Every transaction is EOA-direct on Arbitrum. The Router's unsigned entry points act on (msg.sender, account 0) — no agent key, no Boros relayer, no gas balance, and nothing through the 1delta Composer. Deposits approve the Router.
