Code was transferred to monorepo: flatfeestack/flatfeestack
Service for interacting with the different blockchains. Supported are: Ethereum (ETH), NEO3 (NEO) and Tezos (XTZ). Every blockchain has their own way so each implementation has some small pitfalls.
Every currency has implemented a deploy-method to deploy the smart contract on start up.
If a smart contract will be deployed depends on the [CURRENCY]_DEPLOY-variable in the .env
Please fill out the [CURRENCY]_PRIVATE_KEY and the [CURRENCY]_CONTRACT for each currency before you start.
The Ethereum payout uses a Go-binding which gets generated based on the Flatfeestack.sol.
Information about the tool can be found here:
https://geth.ethereum.org/docs/dapp/native-bindings
It can be generated with:
abigen --pkg main --sol Flatfeestack.sol --out ./contract.go
For the smart contract development have a look at: https://github.com/flatfeestack/payout-eth-contracts
The NEO payout is based on two files:
PayoutNEO.manifest.jsonPayoutNeo.nef
These are generated from the smart contract development repository. https://github.com/flatfeestack/payout-neo-contracts
To fill up the smart contract you need a NEO3 address. If you want to convert the smart contract address to a NEO3-address you can use this code or use the converter linked below. (Important with as prefix when you convert 0x)
noX := strings.TrimPrefix(neo.Contract, "0x")
rawStr, err := hex.DecodeString(noX)
val, _ := util.Uint160DecodeBytesBE(rawStr)
addrRev := address.Uint160ToString(val.Reverse())
if err != nil {
log.Fatalf("Unable to convert address", err)
}
log.Printf("NEO3 address of the smart contract: %v", addrRev)

The Tezos payout happens in the payout-nodejs-service,
because of the missing possibility to interact with a Tezos smart-contract in go.
