Basics

Tributary enables automated recurring payments on Solana through token delegation - users approve payments once, and the protocol handles execution automatically.

Payment Flow

  1. User Approval - User delegates spending authority for specific amounts
  2. Policy Creation - Payment policies define when and how much to pay
  3. Automated Execution - Smart contracts process payments on schedule
  4. Direct Transfer - Funds move directly from user wallets to recipients

Quick Start

pnpm install @tributary-so/payments @tributary-so/sdk @solana/web3.js

import { PaymentsClient } from "@tributary-so/payments";
import { Connection } from "@solana/web3.js";
import { Tributary } from "@tributary-so/sdk";

const connection = new Connection("https://api.mainnet-beta.solana.com");
const tributary = new Tributary(connection, wallet);
const stripe = new PaymentsClient(connection, tributary);

const session = await stripe.checkout.sessions.create({
  mode: "subscription",
  line_items: [{ description: "Pro Plan", unitPrice: 10, quantity: 1 }],
  paymentFrequency: "monthly",
  tributaryConfig: {
    gateway: "CwNybLVQ3sVmcZ3Q1veS6x99gUZcAF2duNDe3qbcEMGr",
    recipient: "YOUR_WALLET",
    trackingId: "user-pro-plan",
  },
});

console.log(session.url); // Share this link!

Check Status

const status = await stripe.subscriptions.checkStatus({
  trackingId: "user-pro-plan",
  userPublicKey: "USER_WALLET",
});

if (status.status === "active") {
  // Grant access
}
