Liquidity Wallet confirmation can be (other transactions can be executed patiently) **These are just a few of Sense's simple interaction steps based on the Goerli test network.** **The trading object can be arbitrarily selected In addition, it is also necessary to note that the number of test coins is only 5 pieces per sample for balanced use.** The core of Sense is to decompose the assets that generate income into their principal and income components and encapsulate them after two fixed-term, mature assets (zero assets and claims). With Zeros and Claims, users can safely borrow at a fixed interest rate and trade at future yields without the risk of liquidation and capital lock-in. **Get more information about Sense** Blog: [https://medium.com/sensefinance](https://medium.com/sensefinance) Twitter: [https://twitter.com/senseprotocol](https://twitter.com/senseprotocol) Docs: [https://docs.sense.finance/](https://docs.sense.finance/) Litepaper: [https://docs.sense.finance/litepaper/](https://docs.sense.finance/litepaper/) App: [https://app.sense.finance/](https://app.sense.finance/) Testnet: [https://testnet.sense.finance/eth-kovan/faucet](https://testnet.sense.finance/eth-kovan/faucet) --- *Originally published on [baikaishui](https://paragraph.com/@xunfa/sense-testnet-interaction-tutorial)*
