prepaidGas Server

The server imcludes validator and executor scripts

• The validator script accepts pending transactions and provides them with confirming signature
• The executor script accepts nice orders and plans corresponding transactions for execution

HTTP

The validator runs http endpoint:

• POST /validate
  • requires body { "origSign": {hexstr 65 bytes user signature}, "message": { "from": {hexstr 40 bytes address}, "nonce": {hexstr number}, "order": {hexstr number}, "start": {hexstr unix timestamp}, "to": {hexstr 40 bytes address}, "gas": {hexstr number}, "data": {hexstr unlimited size data} } }
  • returns {hexstr 65 bytes confirm signature}
• GET /load
  • requires parameters ?offset={number}&reverse={boolean}
  • returns { "id": {uint64 database id}, "validSign": {hexstr 65 bytes confirm signature}, "origSign": {hexstr 65 bytes user signature}, "message": { "from": {hexstr 40 bytes address}, "nonce": {hexstr number}, "order": {hexstr number}, "start": {hexstr unix timestamp}, "to": {hexstr 40 bytes address}, "gas": {hexstr number}, "data": {hexstr unlimited size data} } }

DB

To run the scripts running db is required: source .env && docker run -e POSTGRES_PASSWORD=$POSTGRES_PASSWORD -e POSTGRES_USER=$POSTGRES_USER -p 5432:5432 postgres:15.4

Setup

The .env file is needed to run the scripts, there is .env.sample presented in the repo

Try running with the commands:

go run ./cmd/executor/executor.go
go run ./cmd/validator/validator.go

Executor

There is the IsOrderRisky function in the go_modules/utils/order.go file, modify it to make executor accept more orders
