Examples
Below are a few examples demonstrating how to interact with the contracts using TypeScript and the
ethers library.- 1.Ensure you have Node.js and npm installed.
- 2.Familiarity with TypeScript and blockchain concepts.
First, install the
ethers in your Typescript project library using npm:npm install ethers
Before any interaction, initialize the contracts:
import { ethers } from 'ethers';
// Depending on your network (mainnet or testnet), use the respective address:
const systemContractMainnet = new ethers.Contract(
"0x68Db92A6a78A39DcAFf1745Da9E89E230eF49D3D",
systemStakingContractABI,
provider
);
// If using testnet:
const systemContractTestnet = new ethers.Contract(
"0x52ab0fe2c3a94644de0888a3ba9ea1443672e61f",
systemStakingContractABI,
provider
);
// Initialize the Staking Read Contract (common for both networks):
const stakingReadContract = new ethers.Contract(
"0x04c22afae6a03438b8fed74cb1cf441168df3f12",
stakingReadContractABI,
provider
);
Check the activated bucket types:
async function getBucketTypes() {
const types = await stakingReadContract.contractStakeBucketTypes("0x52ab0fe2c3a94644de0888a3ba9ea1443672e61f");
console.log("Available bucket types:", types);
}
To create a stake bucket of 10,000 IOTX for a 30-day duration:
async function createBucket() {
const tx = await systemContract.stake(
518400, // 30day equivalent in IoTeX blocks
"io1tfke5nfwryte6nultpmqefadgm0dsahm2gm63k", // delegate profile address
{value: 10000} // stake deposit amount in IOTX
);
await tx.wait();
console.log("Bucket created successfully!");
}
Increase the stake amount a snd duration of an existing bucket:
async function expandBucket() {
const tx = await systemContract.expandBucket(
1, // Bucket token id
20000, // new amount (final)
1036800, // new duration (60 days)
{value: 10000} // new amount supplied
);
await tx.wait();
console.log("Bucket expanded successfully!");
}
Transferring a bucket is akin to transferring an ERC-721 token:
async function transferBucket() {
const tx = await systemContract.transferFrom(
"io1tfke5nfwryte6nultpmqefadgm0dsahm2gm63k", // from address
"io12mgttmfa2ffn9uqvn0yn37f4nz43d248l2ga85", // to address
1 // bucket token id
);
await tx.wait();
console.log("Bucket transferred successfully!");
}
After creating a bucket, you might need to unlock, unstake, or even withdraw:
async function unlockBucket() {
const tx = await systemContract.unlock(1); // pass the token id
await tx.wait();
console.log("Bucket unlocked successfully!");
}
async function unstakeBucket() {
const tx = await systemContract.unstake(1); // pass the token id
await tx.wait();
console.log("Bucket unstaked successfully!");
}
async function withdraw() {
const tx = await systemContract.withdraw(
1, // Token id
"io1tfke5nfwryte6nultpmqefadgm0dsahm2gm63k" // Recipient address
);
await tx.wait();
console.log("Withdrawal successful!");
}
These are the foundational steps for interacting with IIP-13 contracts, that allows the creation of Liquid Staking solutions. Liquid staking allows users to access the benefits of staking in a blockchain network while still maintaining liquidity and flexibility over their staked assets, which create a more attractive and versatile staking experience.
For more advanced operations and deeper insights, refer to the IIP-13 official documentation and the contract's source code.
