Integration Guide

This guide is for helping developers integrating Ergo into exchanges, wallets, pools wallets etc.
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.
- How to set up a node: https://ergoplatform.org/en/blog/2019_12_02_how_to_setup/, https://github.com/ergoplatform/ergo/wiki/Set-up-a-full-node
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
- /wallet/deriveNextKey to derive a new key according to EIP-3 (BIP 44 implementation for Ergo)
- /wallet/balances to get wallet balance (for all the addresses)
- /wallet/transactions to get wallet transactions (for all the addresses)
If you are going to do wallet logic externally, you can do it with a library and also the block explorer. Please note, you need to consider mempool transactions to avoid double-spending generation.
Available libraries are:
- ergo-wallet made in Java
- ergo-lib in Rust
- ergo-ts in TypeScript
- ergo-golang in Go
