trUSD and strUSD both trade on @CurveFinance. There are two ways to use it. The first is swapping. You buy trUSD with USDC in one pool and move between strUSD and trUSD in the other, which lets you enter and exit a yield position at market price rather than waiting out the 7-day cooldown. The second is providing liquidity. You supply either side of a pool, or both, and receive LP shares representing your portion of it. From there you earn a share of the fees on every swap routed through, plus the yield accruing to the pool. Currently 4.74% on strUSD/trUSD. Then there are Cores. Supplying strUSD/trUSD earns 15x, against 5x for holding strUSD on its own. A balanced position puts half your capital into trUSD, which does not accrue the strategy yield that strUSD does. So a pool pays a lower rate than holding strUSD, and the trade is some yield for more Cores. Curve incentives are on the way, with gauge weight voted in for the next epoch. And as of today both pools are live on @ConvexFinance, where you can stake your LP shares for rewards on top. Links below.
