go-wallet
A work-in-progress Bitcoin wallet
Descriptors
go-wallet is designed around Bitcoin Descriptors. It implements a Output Script Descriptors language parser which returns valid outputs scripts. The script package also implements a Output Script DSL to build scripts with a fluent API.

Example
The following example shows how to parse a Script and print an address.
package main
import (
"fmt"
"log"
"github.com/qustavo/go-wallet"
"github.com/qustavo/go-wallet/script"
)
func main() {
w, err := wallet.NewWallet(`
wsh(sortedmulti(2,
0375e00eb72e29da82b89367947f29ef34afb75e8654f6ea368e0acdfd92976b7c,
03a1b26313f430c4b15bb1fdce663207659d8cac749a0e53d70eff01874496feff,
03c96d495bfdd5ba4145e3e046fee45e84a8a48ad05bd8dbb395c011a32cf9f880
))`, script.Mainnet)
if err != nil {
log.Fatal(err)
}
fmt.Printf("> addr: %s\n", w.Address())
}
The same can be expresses using the script API.
package main
import (
"fmt"
"log"
. "github.com/qustavo/go-wallet/script"
)
func main() {
script := Wsh(Sortedmulti(2,
"0375e00eb72e29da82b89367947f29ef34afb75e8654f6ea368e0acdfd92976b7c",
"03a1b26313f430c4b15bb1fdce663207659d8cac749a0e53d70eff01874496feff",
"03c96d495bfdd5ba4145e3e046fee45e84a8a48ad05bd8dbb395c011a32cf9f880",
))
eval, err := script.Eval()
if err != nil {
log.Fatal(err)
}
fmt.Printf("> addr: %s\n", eval.Address(Mainnet))
}
