# Escrow (Go)

This directory contains Go examples demonstrating how to create, finish, and cancel escrows on the XRP Ledger.

## Setup

All commands should be run from this `go/` directory.

Install dependencies before running any examples:

```sh
go mod tidy
```

---

## Send Fungible Token Escrow

```sh
go run ./send-fungible-token-escrow
```

The script issues an MPT and Trust Line Token, setting up both to be escrowable. It then creates and finishes a conditional escrow with the MPT and a timed escrow with the Trust Line Token.

```sh
