VeMMT SDK

A TypeScript SDK for interacting with the VeMMT protocol.

QuickStart

View Functions (read-only operations)

import { getFullnodeUrl, SuiClient } from '@mysten/sui/client';
import { Transaction } from '@mysten/sui/transactions';
import { VeMMT } from '@mmt-finance/ve-sdk';

const client = new SuiClient({
  url: getFullnodeUrl('testnet'),
});

const ve = new VeMMT(client, 'testnet');

// View functions accept optional Transaction (null for new transaction)
const whitelistedIncentives = await ve.getAllWhitelistedIncentives(null);
console.log(JSON.stringify(whitelistedIncentives, null, 2));

Transaction Functions (mutate transactions in-place)

import { getFullnodeUrl, SuiClient } from '@mysten/sui/client';
import { Transaction } from '@mysten/sui/transactions';
import { VeMMT } from '@mmt-finance/ve-sdk';

const client = new SuiClient({
  url: getFullnodeUrl('testnet'),
});

const ve = new VeMMT(client, 'testnet');
const tx = new Transaction();

// Chain multiple operations on the same transaction
ve.createBond(tx, coinInput, unlockTime, recipient);
ve.addIncentive(tx, gaugeId, incentiveCoin, coinType);

// Execute the transaction
const result = await client.signAndExecuteTransaction({
  signer: keypair,
  transaction: tx,
});
