TRAVA STATION SDK

import {actions} from "trava-station-sdk"

Với các actions:

Utilities

Pull token

const pull_token_action = new actions.basic.PullTokenAction(
    token: String,
    from: String,
    amount: uint256
)

Send token

const send_token_action = new actions.basic.SendTokenAction(
    token: String,
    to: String,
    amount: uint256
)

Wrap token

const pull_token_action = new actions.basic.PullTokenAction()
const wrap_token_action = new actions.basic.WrapBnbAction(
    amount: uint256
)

Unwrap token

const unwrap_token_action = new actions.basic.UnwrapBnbAction(
    amount: uin256,
    to: String
)

Pancake

Swap

const swapUtil = new SwapUtil(web3);
const info = new await swapUtil.getInformationFromInput(tokenAddr1, tokenAddr2, slipparage, amount);
const minimumReceive = info.minimumReceive
const priceImpact = info.priceImpact;
const path = info.path;

const swap_token_action = new actions.pancakeswap.PancakeSwapV2(
    amountIn: uint256,
    amountOutMin: 0,
    path: path,
    to: _to address,
    deadline: timestamp + 30 * 60 * 1000
    from: _from address
)

Orai Liquid Staking

Stake

const orai_ls_stake_action = new actions.OraiLiquidStakingStakeAction(
    amount, 
    from,
    contract address
)

Unstake

const orai_ls_unstake_action = new actions.OraiLiquidStakingUnstakeAction(
    amount,
    from
)

WithdrawUnstake

const orai_ls_withdraw_unstake_action = new actions.OraiLiquidStakingWithdrawUnstakedAction(
    to
)

Execute actions

Sau khi có được các action xong, để execute Freight giả sử kết hợp action supply và borrow, repay và withdraw

import {Recipe} from "trava-station-sdk";

const recipe = new Recipe(
    "ten action = address user + timestamp",
    [
        swap_token_action,
        orai_ls_stake_action,
        orai_ls_unstake_action,
        send_token_action
    ]
)

const encoded = recipe.encodeForDsProxyCall();

//sau đó dùng contract Proxy để execute (abi e để dưới), address của contract này là proxy của người dùng
let tx;
if(co action su dung BNB nhu wrap) {
    tx = await proxyCOntract.execute(encoded[0], encoded[1], {value: total amountBNB});

} else {
    tx = await proxyContract.execute(encoded[0], encoded[1])
}

await tx.wait();

Cách approve token

gọi hàm approve trong abi ERC20 token tham số truyền vào là:

• address token
• lượng amount cần approve

Approve token trong các Action

Cách approve

• Trừ đồng BNB, các đồng token khác cần approve
• Contract gọi hàm approve trong abi là address BEP20 token
• 2 tham số trong approve là:
  • tham số đầu tiên là address _to
  • tham số thứ 2 là amount đang dùng
• tham số đầu tiên của approve luôn là smartWallet
• Chỉ khi from là wallet mới cần approve, from là smart wallet thì không cần

Các actions cần approve

Pull token: approve token cần pull

Swap token: approve token cần swap

Orai LS Stake: approve orai token

publish orchai-combinator-bsc-sdk to npm

go to file tsconfig.json, if module != "ESNext", change module to "ESNext"

delete two folder /esm /umd if they exist

run

npm run build

after build, to publish repo on npm, change version repo in package.json (can't publish a repo have same version with repo existing on npm), if you use repo for test, please add "testnet" before each version and increase version after each time publish

if you don't login npm, please create account npm on website https://www.npmjs.com/, then login npm in terminal by running command

npm login

after you login success, you can publish repo on npm by following command

npm publish
