Single Release Lifecycle

Step by Step Guide to implement Escrow's Single Release Lifecycle

Important

It does not work for a real use case, only for testing purposes. But if you want to implement it, you can use the code below as a reference and customize it to your needs.

Create a Next.js Project#

Start by creating a new Next.js project with TypeScript and Tailwind CSS. In order to make easier the setup, please use the path alias with "@/":

npx create-next-app@latest

Navigate to your project directory:

cd my-trustless-app

Install Trustless Work Blocks#

Install the main library package:

npm

npm install @trustless-work/blocks

Run the CLI Setup

Initialize your project with the Trustless Work CLI:

npx trustless-work init

What the init command does:

• Installs shadcn/ui components (with interactive prompts)

• Installs required dependencies: @tanstack/react-query, @trustless-work/escrow, axios, zod, react-hook-form, @creit.tech/stellar-wallets-kit, react-day-picker, etc.

• Creates .twblocks.json configuration file

• Optionally wires providers into your Next.js app/layout.tsx

Environment Configuration

Documentation

Create a .env file in your project root:

.env

# Required: Your Trustless Work API key 
NEXT_PUBLIC_API_KEY=your_api_key_here

Add Wallet Connectivity

Add wallet connectivity to your app:

npx trustless-work add wallet-kit

Wrap your app with the WalletProvider:

Wrap your app with the WalletProvider in your layout.tsx:

app/layout.tsx

return (
    <WalletProvider>{children}</WalletProvider> 
);

Example usage in a page:

Add wallet connectivity to your app:

app/page.tsx

"use client";

import { WalletButton } from "@/components/tw-blocks/wallet-kit/WalletButtons";

export default function Home() {
  return (
    <div className="font-sans grid grid-rows-[20px_1fr_20px] items-center justify-items-center min-h-screen p-8 pb-20 gap-16 sm:p-20">
      <header className="flex justify-between items-center w-full">
        <h2 className="text-2xl font-bold">Trustless Work</h2>

        {/* Wallet Button */}
        <WalletButton />
      </header>
    </div>
  );
}

Add Helpers

Add helpers to your app:

npx trustless-work add helpers

Add Tanstack Query

Add Tanstack Query to your app:

npx trustless-work add tanstack

Add Handle Errors

Add Handle Errors to your app:

npx trustless-work add handle-errors

Add Providers (If you skipped the init command)

Add Providers to your app:

npx trustless-work add providers

Add Single Release Escrows Components

Add Single Release Escrows to your app:

npx trustless-work add escrows/single-release

Add Single-Multi Release Escrows Components

Add Single-Multi Release Escrows to your app:

npx trustless-work add escrows/single-multi-release

Add Escrows by Role Cards

Add Escrows by Role Cards to your app:

npx trustless-work add escrows/escrows-by-role/cards

Import Actions

In the code, there are some actions commented out. You can uncomment them and import them from the single-release block. See the notes in the escrows by role or by signer components.

Commented Out Code

escrows/escrows-by-role/details/Actions.tsx

return (
    <div className="flex items-start justify-start flex-col gap-2 w-full">
      {/* You can add the buttons here, using the buttons from the blocks. These actions are conditional based on the escrow flags and the user roles. */}
      {hasConditionalButtons && (
        <div className="flex flex-col gap-2 w-full">
          {/* UpdateEscrowDialog component should be rendered based on the escrow type. It means that if the selectedEscrow.type is "single-release", then the UpdateEscrowDialog (from the single-release block) component should be rendered. If the selectedEscrow.type is "multi-release", then the UpdateEscrowDialog (from the multi-release block) component should be rendered. */}
          {/* {shouldShowEditButton && <UpdateEscrowDialog />} */}

          {/* Works only with single-release escrows */}
          {/* Only appears if the escrow has balance */}
          {/* {shouldShowDisputeButton && <DisputeEscrowButton />} */}

          {/* Works only with single-release escrows */}
          {/* Only appears if the escrow is disputed */}
          {/* {shouldShowResolveButton && <ResolveDisputeDialog />} */}

          {/* Works only with single-release escrows */}
          {/* Only appears if all the milestones are approved */}
          {/* {shouldShowReleaseFundsButton && <ReleaseEscrowButton />} */}
        </div>
      )}

      <FundEscrowDialog />
    </div>
  );

Actions Imported

escrows/escrows-by-role/details/Actions.tsx

// If you need both types, you should import both versions to update escrow
import { UpdateEscrowDialog } from "../../single-release/update-escrow/dialog/UpdateEscrow";
/* import { UpdateEscrowDialog as UpdateEscrowDialogMultiRelease } from "../../multi-release/update-escrow/dialog/UpdateEscrow"; */
import { FundEscrowDialog } from "../../single-multi-release/fund-escrow/dialog/FundEscrow";
import { DisputeEscrowButton } from "../../single-release/dispute-escrow/button/DisputeEscrow";
import { ResolveDisputeDialog } from "../../single-release/resolve-dispute/dialog/ResolveDispute";
import { ReleaseEscrowButton } from "../../single-release/release-escrow/button/ReleaseEscrow";

return (
    <div className="flex items-start justify-start flex-col gap-2 w-full">
      {/* You can add the buttons here, using the buttons from the blocks. These actions are conditional based on the escrow flags and the user roles. */}
      {hasConditionalButtons && (
        <div className="flex flex-col gap-2 w-full">
          {/* UpdateEscrowDialog component should be rendered based on the escrow type. It means that if the selectedEscrow.type is "single-release", then the UpdateEscrowDialog (from the single-release block) component should be rendered. If the selectedEscrow.type is "multi-release", then the UpdateEscrowDialog (from the multi-release block) component should be rendered. */}
          {shouldShowEditButton && <UpdateEscrowDialog />}

          {/* Works only with single-release escrows */}
          {shouldShowDisputeButton && <DisputeEscrowButton />}

          {/* Works only with single-release escrows */}
          {shouldShowResolveButton && <ResolveDisputeDialog />}

          {/* Works only with single-release escrows */}
          {shouldShowReleaseFundsButton && <ReleaseEscrowButton />}
        </div>
      )}

      <FundEscrowDialog />
    </div>
  );

Manual Provider Setup

Wrap your app with the required providers in this specific order:

app/layout.tsx

import type { Metadata } from "next";
import { Geist, Geist_Mono } from "next/font/google";
import "./globals.css";
import { ReactQueryClientProvider } from "@/components/tw-blocks/providers/ReactQueryClientProvider";
import { TrustlessWorkProvider } from "@/components/tw-blocks/providers/TrustlessWork";
import { WalletProvider } from "@/components/tw-blocks/wallet-kit/WalletProvider";
import { EscrowProvider } from "@/components/tw-blocks/providers/EscrowProvider";
import { EscrowDialogsProvider } from "@/components/tw-blocks/providers/EscrowDialogsProvider";
import { EscrowAmountProvider } from "@/components/tw-blocks/providers/EscrowAmountProvider";
import { Toaster } from "@/components/ui/sonner";

const geistSans = Geist({
  variable: "--font-geist-sans",
  subsets: ["latin"],
});

const geistMono = Geist_Mono({
  variable: "--font-geist-mono",
  subsets: ["latin"],
});

export const metadata: Metadata = {
  title: "Create Next App",
  description: "Generated by create next app",
};

export default function RootLayout({
  children,
}: Readonly<{
  children: React.ReactNode;
}>) {
  return (
    <html lang="en">
      <body
        // optional: use geistSans.variable and geistMono.variable
        className="antialiased"
      >
        <ReactQueryClientProvider>
          <TrustlessWorkProvider>
            <WalletProvider>
              <EscrowProvider>
                <EscrowDialogsProvider>
                  <EscrowAmountProvider>
                    {children}

                    <Toaster />
                  </EscrowAmountProvider>
                </EscrowDialogsProvider>
              </EscrowProvider>
            </WalletProvider>
          </TrustlessWorkProvider>
        </ReactQueryClientProvider>
      </body>
    </html>
  );
}

Provider Order MattersThe providers must be nested in this exact order for proper functionality.

Example usage in a page:

Now, you are able to interact with the entire escrow lifecycle.

app/page.tsx

"use client";

import { EscrowsByRoleCards } from "@/components/tw-blocks/escrows/escrows-by-role/cards/EscrowsCards";
import { InitializeEscrowDialog } from "@/components/tw-blocks/escrows/single-release/initialize-escrow/dialog/InitializeEscrow";
import { WalletButton } from "@/components/tw-blocks/wallet-kit/WalletButtons";

export default function Home() {
  return (
    <div className="font-sans grid grid-rows-[20px_1fr_20px] items-center justify-items-center min-h-screen p-8 pb-20 gap-16 sm:p-20">
      <header className="flex justify-between items-center w-full">
        <h2 className="text-2xl font-bold">Trustless Work</h2>
        <WalletButton />
      </header>
      <main className="flex flex-col gap-[32px] row-start-2 items-center sm:items-start">
        <div className="container">
          <div className="flex w-full mb-4 justify-end">
            <div className="flex w-1/6">
              <InitializeEscrowDialog />
            </div>
          </div>

          <EscrowsByRoleCards />
        </div>
      </main>
    </div>
  );
}

All the blocks were added, now use them!You already have all the required blocks to start using the single-release escrow lifecycle.

Final UI

By using these components, you'll be able to completed the entire escrow lifecycle.

Important Usage Advice- This cards components works by role. In the filters section, you can select the role you want to see the escrows for. Based on that, the actions buttons will be rendered. - Before you start using the UI, you must add the USDC asset to your wallet. If not, you wont be able to interact with Trustless Work.
