Stateless cryptocurrency API.
Requirements:
- Bitcoin: electrum wallet in $PATH
- Ethereum:
export INFURA_API_KEY=...from infura.io (it's free). It'll work even without, but there are some limits on queries.
Start:
go get -u code.dumpstack.io/lib/cryptocurrency
go test -v code.dumpstack.io/lib/cryptocurrency/...
Usage:
package main
import (
"log"
"code.dumpstack.io/lib/cryptocurrency"
)
func main() {
c := cryptocurrency.Bitcoin
dest := "mk84dHbQoUHWaWGuYspx6GXWgcjB9CuQqw"
// c := cryptocurrency.Ethereum
// dest := "0xD98660C76443A8A043a19499048EeC4FB06f2581"
// c := cryptocurrency.Cardano
// dest := "Ae2tdPwUPEZ68cfEjZjKKRabiqbazMtP69uGaM2pMZRg87fvn4FGvR95BEV"
err := c.Testnet(true)
if err != nil {
log.Fatal(err)
}
seed, address, err := c.GenWallet()
if err != nil {
log.Fatal(err)
}
log.Println(seed, address)
balance, err := c.Balance(seed)
log.Println(balance)
if err != nil {
log.Fatal(err)
}
valid, err := c.Validate(dest)
if err != nil {
log.Fatal(err)
}
if valid {
log.Println("address", dest, "is valid")
} else {
log.Fatal("address", dest, "is invalid")
}
amount := float64(0.1)
tx, err := c.Send(seed, dest, amount)
// tx, err := c.SendUnits(seed, dest, wei) // precise version
if err != nil {
log.Println("here it'll exit because there's no money inside new wallet")
log.Fatal(err)
}
log.Println(tx)
}
