Token swap

Oracle service for DAOBet validators.

Configure

in conf.json file Configure next fields:

  • accountName : paste your account name
  • KeyProvider : paste your account private key
  • ethNet : paste your infura id project

For getting the infura project id you have to register on infura.io and create a project

Run

using docker:

docker pull daocasino/oracle
docker run -d -v PATH_TO_CONFIG_IN_HOST_MACHINE:/app/conf.json daocasino/oracle

using nodejs:

npm install
npm run prod
node build/oracle.js

How it works?

Workflow

  1. User call convert(...) on smart contract in ethereum mainnet
  2. Smart contract in ethereum while transfering BET tokens from users, and emit event Swap
  3. Oracle reads events from ethereum smart contract and proposes to eosio.msig transfer BET tokens from eosio.bridge to account from events. if this proposal already exists, oracle approves this proposal.
  4. When proposal has been approved by 2/3 + 1 validators eosio.bridge sends tokens to user.
