How Tessant turns staking yield into repayment.

The model is simple: earn on the full collateral base, pay interest on a smaller debt balance, and route the difference toward principal.

Position structure

Tessant uses slisBNB as yield-bearing collateral and lisUSD as the borrowed asset. The user keeps ownership of the position. Tessant coordinates the repayment path; it does not advertise a fixed yield or hide the underlying lending venue.

  1. BNB is staked into slisBNB.
  2. slisBNB is supplied to a Lista lending market.
  3. The user borrows lisUSD at a chosen starting LTV.
  4. Available base staking value is periodically converted to lisUSD.
  5. The lisUSD is applied to the outstanding debt.

Economics

annual rewards = collateral value × staking APRannual interest = lisUSD debt × borrow APRnet paydown = rewards − interestbreak-even LTV = staking APR ÷ borrow APR

At a 0.886% base staking APR and 4.5288% borrow APR, the illustrative break-even LTV is about 19.6%. This relationship changes whenever either rate changes. The planner therefore reads current reference data instead of treating the threshold as permanent.

Rate data

The app reads Lista's current slisBNB staking rate and slisBNB/lisUSD market terms, plus a BNB/USDT reference price from Binance. Temporary launchpool incentives are excluded from the primary repayment calculation.

Execution path

The production path is designed around user-authorized transactions: stake BNB, supply collateral, borrow lisUSD, then periodically harvest and repay. The first release keeps each transaction inspectable and uses the official Lista venue for the underlying position.

The BSC Testnet contract is a separate educational sandbox. It uses a fixed reference price and mock lisUSD because Lista's production lending market is on mainnet.

Material risks

  • Borrowing rates can rise or staking returns can fall, which may reverse estimated paydown.
  • BNB price declines can move the position toward liquidation even when debt is being repaid.
  • slisBNB and lisUSD depend on their underlying protocols, contracts, liquidity and market pricing.
  • Swaps and repayment transactions introduce execution costs and may be uneconomic for very small positions.
  • The Tessant contracts and interface are not audited. The testnet sandbox uses mock assets and is not a production lending venue.
