Basic Function Signature Lookup
package main
import (
"context"
"fmt"
"log"
"github.com/0xhyim/fourbyte"
)
func main() {
response, err := fourbyte.GetFunctionSignatures(context.Background(), fourbyte.WithHexSignature("0x1249c58b"))
if err != nil {
log.Fatal(err)
}
// "mint()"
fmt.Println(response.Signatures[0].TextSignature)
}Signature Lookup (following Next)
package main
import (
"context"
"fmt"
"log"
"github.com/0xhyim/fourbyte"
)
func main() {
signatures := []fourbyte.Signature{}
response, err := fourbyte.GetFunctionSignatures(context.Background(), fourbyte.WithTextSignature("WETH"))
if err != nil {
log.Fatal(err)
}
signatures = append(signatures, response.Signatures...)
for response.Next != nil {
response, err = response.Next.Follow(context.Background())
if err != nil {
log.Fatal(err)
}
signatures = append(signatures, response.Signatures...)
}
fmt.Println(signatures)
