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:

go mod tidy

Send Fungible Token Escrow

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.
