Usage Examples
Mint Stablecoins
import { Transaction, coinWithBalance } from "@mysten/sui/transactions";
import { SuiClient, getFullnodeUrl } from "@mysten/sui/client";
import { Ed25519Keypair } from "@mysten/sui/keypairs/ed25519";
import { StableLayerClient } from "stable-layer-sdk";
const client = new StableLayerClient({
network: "mainnet",
sender: "0xYOUR_ADDRESS",
});
const suiClient = new SuiClient({ url: getFullnodeUrl("mainnet") });
const keypair = Ed25519Keypair.fromSecretKey(YOUR_PRIVATE_KEY);
const tx = new Transaction();
await client.buildMintTx({
tx,
stableCoinType: "0x6d9fc...::btc_usdc::BtcUSDC",
usdcCoin: coinWithBalance({
balance: BigInt(1_000_000),
type: "0xdba34...::usdc::USDC",
})(tx),
amount: BigInt(1_000_000),
});
const result = await suiClient.signAndExecuteTransaction({
transaction: tx,
signer: keypair,
});
Burn Stablecoins
const tx = new Transaction();
await client.buildBurnTx({
tx,
stableCoinType: "0x6d9fc...::btc_usdc::BtcUSDC",
amount: BigInt(500_000),
});
await suiClient.signAndExecuteTransaction({ transaction: tx, signer: keypair });
Claim Rewards
const tx = new Transaction();
await client.buildClaimTx({
tx,
stableCoinType: "0x6d9fc...::btc_usdc::BtcUSDC",
});
await suiClient.signAndExecuteTransaction({ transaction: tx, signer: keypair });
Query Supply
const totalSupply = await client.getTotalSupply();
const btcUsdcSupply = await client.getTotalSupplyByCoinType("0x6d9fc...::btc_usdc::BtcUSDC");
