  7 | This repo gives examples for how to use the [@sharkyfi/client](https://www.npmjs.com/package/@sharkyfi/client) library to interact with the [Sharky](https://sharky.fi) solana program. It doesn't yet contain the client's code, because we use monorepo and publish package from there. But eventually the client's code will be migrated.
  8 | 
  9 | The `examples` directory contains scripts that provide a reference for performing automated lending actions. You can copy-paste code from there into your own code, or run the scripts directly.
 10 | 
 11 | Keep in mind that this repo and the Sharky library are licensed under [GPLv3](https://www.gnu.org/licenses/gpl-3.0.en.html).
 12 | 
 13 | ## How to use the package
 14 | 
 15 | The recommended way is to fork this repo and use examples as a starting point for your scripting.
 16 | 
 17 | The more custom alternative is to run:
 18 | 
 19 | ```
 20 | npm install @sharkyfi/client
 21 | ```
 22 | 
 23 | And write your own scripts from scratch.
 24 | 
 25 | ## Examples
 26 | 
 27 | To run the scripts, run `yarn` or `npm install`, then:
 28 | 
 29 | Get the current list of orderbooks (name and pubkey):
 30 | 
 31 | ```bash
 32 | npx ts-node examples/list-order-books.ts --wallet-path ~/.config/solana/id.json
 33 | ```
 34 | 
 35 | Place a loan offer on an orderbook:
 36 | 
 37 | ```bash
 38 | npx ts-node examples/place-offer.ts --wallet-path ~/.config/solana/id.json --order-book <order-book-pubkey> --amount-sol 1
 39 | ```
 40 | 
 41 | List your current offers:
 42 | 
 43 | ```bash
 44 | npx ts-node examples/list-offers.ts --wallet-path ~/.config/solana/id.json
 45 | ```
 46 | 
 47 | Revoke an offer:
 48 | 
 49 | ```bash
 50 | npx ts-node examples/revoke-offer.ts --wallet-path ~/.config/solana/id.json --loan <loan-pubkey>
 51 | ```
 52 | 
 53 | ## Gotchas / things to know about how our data is structured
 54 | 
 55 | ### APR and APY
 56 | 
 57 | We originally named a property on loans and orderbooks "APY" when actually using it mathematically as APR. We've corrected this on the frontend, but in the data structure that is returned from the chain data, `orderBook.apy.fixed?.apy` is actually APR, as is `loan.data.loanState.taken?.taken.apy.fixed!.apy`.
 58 | 
 59 | Additionally, those are stored as millpercents — thousandths of a percent, to allow for higher precision while being stored as integers.
 60 | 
 61 | To get regular APR and APY as percents from the values we store on chain:
 62 | 
 63 | ```js
 64 | import { aprToApy, apyToApr, aprToInterestRatio, interestRatioToApr } from '@sharkyfi/client'
 65 | 
 66 | // Get values from the loan and orderbook
 67 | // for orderbooks:
 68 | const apr = orderBook.apy.fixed!.apy / 1000
 69 | // or for taken loans:
 70 | const apr = loan.data.loanState.taken?.taken.apy.fixed!.apy / 1000
 71 | 
 72 | const principalLamports = loan.data.principalLamports.toNumber()
 73 | const feePermillicentage = orderBook.feePermillicentage
 74 | const durationSeconds =
 75 |     loan.data.loanState.taken?.taken.terms.time?.duration.toNumber() ||
 76 |     loan.data.loanState.offer?.offer.termsSpec.time?.duration.toNumber()
 77 | 
 78 | // Calculations
 79 | const interestRatio = aprToInterestRatio(apr, durationSeconds)
 80 | const interestWithFeeLamports = interestRatio * principalLamports
 81 | const totalOwedLamports = principalLamports + interestWithFeeLamports
 82 | const feeLamports = Math.floor((interestWithFeeLamports * feePermillicentage) / 100_000)
 83 | const interestWithoutFeeLamports = interestWithFeeLamports - feeLamports
 84 | const interestRatioAfterFee = interestWithoutFeeLamports / principalLamports
 85 | const aprAfterFee = interestRatioToApr(interestRatioAfterFee, durationSeconds)
 86 | const apyAfterFee = aprToApy(aprAfterFee)
 87 | 
 88 | console.log({
 89 |   interestRatio, // Shown to borrowers
 90 |   interestWithFeeLamports, // Shown to borrowers
 91 |   totalOwedLamports, // Shown to borrowers
 92 |   apyAfterFee, // Shown to lenders
 93 | })
 94 | ```
 95 | 
 96 | For example, given these inputs, you will get these values:
 97 | 
 98 | ```js
 99 | const principalLamports = 1e9
100 | const apr = 145365 / 1000
101 | const feePermillicentage = 16000
102 | const durationSeconds = 7 * 24 * 60 * 60
103 | 
104 | // ...calculations
105 | 
106 | console.log({
107 |   interestRatio, // 0.028270453175256227 (shown as 2.82%)
108 |   interestWithFeeLamports, // 28270453 (shown as 0.028 SOL)
109 |   totalOwedLamports, // 1028270453 (shown as 1.028 SOL)
110 |   apyAfterFee, // 239.9988789793601 (shown as 240%)
111 | })
112 | ```

114 | # How to get historical events
115 | 
116 | It depends for what purpose. If you want to get parsed transactions programmatically from the beginning of time, please refer to our official partner - Hello Moon, if you want to just do explorative analysis via SQL, we have pre-parsed table on Dune, if you want some super custom integration, we can give you acess to our own database for some unique use-cases.
