API Reference

StableLayerClient

import { StableLayerClient } from "stable-layer-sdk";

const client = new StableLayerClient({
  network: "mainnet" | "testnet",
  sender: "0xYOUR_SUI_ADDRESS",
});

Transaction Methods

buildMintTx(options)

Mint stablecoins by depositing USDC. Automatically deposits into vault farm.

buildBurnTx(options)

buildClaimTx(options)

Claim accumulated yield farming rewards.

Returns the total stablecoin supply across all coin types.

getTotalSupplyByCoinType(type: string)

Returns the supply for a specific stablecoin type.

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");
