Token Gating

Gate features behind token holdings. Check balances, set minimums, create tiers.

Direct Trading

Buy, sell, and burn tokens directly on-chain. Works with any connected EVM wallet.

Wallet Support

Connect any EVM wallet via wagmi. Build transactions, sign in the wallet, submit.

Revenue Routing

Route app revenue to token holders. Integrate dividends with a few lines of code.

Quick start

Examples using viem

token-gate.ts
import { createPublicClient, http } from 'viem';
import { base } from 'viem/chains';

const client = createPublicClient({
  chain: base,
  transport: http(),
});

// Check ERC20 token balance
const balance = await client.readContract({
  address: 'TOKEN_CONTRACT_ADDRESS',
  abi: erc20Abi,
  functionName: 'balanceOf',
  args: [walletAddress],
});

const minRequired = 1_000_000_000_000_000_000n; // 1 token (18 decimals)

if (balance >= minRequired) {
  // Grant access to premium features
} else {
  console.log(`Need ${minRequired - balance} more tokens`);
}
