Integration Guide

This guide is for helping developers integrating Ergo into exchanges, wallets, pools wallets etc.

Introduction

Some quick facts useful for an integration:

like Bitcoin, a transaction in Ergo has multiple inputs and outputs. Unspent outputs are single-use entities. However, Ergo is built from scratch thus scripts and transaction format are different.
like in Bitcoin, there are some standard scripts in Ergo associated with addresses, e.g. P2PK addresses. There's an article on address scheme available: https://ergoplatform.org/en/blog/2019_07_24_ergo_address/
Ergo has inbuilt wallet API which is enough for most use-cases. API has Swagger interface (on 127.0.0.1:9053 by default in the mainnet, 127.0.0.1:9052 in the testnet) with descriptions and examples for API methods.

Node wallet has UI available @ 127.0.0.1:9053/panel by default on the mainnet (127.0.0.1:9052/panel on the testnet). Main methods:

/wallet/init and /wallet/restore to create a wallet (and a secret mnemonic) and restore wallet from mnemonic
/wallet/unlock to unlock the wallet (it is unlocked after init but locked after restart)
/wallet/lock to lock the wallet
/wallet/payment/send to send a simple payment
/wallet/status to get wallet status
