How TIDE works
The market
TIDE is a single-stablecoin credit market on Arc. Suppliers deposit USDC and receive tUSDC, an interest-bearing share token. Borrowers post curated collateral — starting with WETH and wBTC — and draw USDC against it.
Arc and USDC
Arc uses USDC as its native gas token. TIDE never wraps USDC. The pool interacts with the canonical ERC-20 interface at 0x3600…0000 (6 decimals). Native 18-decimal balances are used only for gas.
Rates
Interest follows a kinked utilization model. As more of the pool is borrowed, the borrow rate rises slowly to the kink, then steeply after it. Supplier yield is real demand, not emissions.
Risk
Each market has its own LTV, liquidation threshold and debt ceiling. Health is collateral value times the liquidation threshold, divided by debt. Below 1.0 the position can be liquidated with a close factor and a bonus to the liquidator. Tide Level maps that health onto a single line.
Oracles
Prices pass through a router with staleness and deviation guards. A push oracle is used until a production feed is bound. Stale or zero prices halt new risk.
