Convert a ScVal to other type - Stellar Developer Docs

Soroban Contract Value (ScVal) is a custom type defined within the Soroban runtime environment that represents other data types such as strings, bytes, and more complex structures used within smart contracts in a format that that the soroban runtime can process, store and retrieve efficiently.

ScVal to bytes

// An ScVal bytes value
const myScVal = StellarSdk.xdr.ScVal.fromXDR("AAAADQAAAARQ/8AB", "base64");
// Convert the ScVal to a Buffer
const bytesFromScVal = StellarSdk.scValToNative(myScVal);

# Convert the ScVal to bytes
bytes_from_sc_val = stellar_sdk.scval.from_bytes("AAAADQAAAARQ/8AB")

ScVal to address

// An ScVal Address value
const myScVal = StellarSdk.xdr.ScVal.fromXDR(
  "AAAAEgAAAAAAAAAAmds+PBjjrhZAv1aCM4n4EbU6ycAbK5HqxcUsumDFyf4=",
  "base64",
);
// Convert the ScVal to an Address
const addressFromScVal = StellarSdk.Address.fromScVal(myScVal);

# Convert the ScVal to address
address_from_sc_val = stellar_sdk.scval.from_address("AAAAEgAAAAAAAAAAmds+PBjjrhZAv1aCM4n4EbU6ycAbK5HqxcUsumDFyf4=")

ScVal to String

// An ScVal string value
const myScVal = StellarSdk.xdr.ScVal.fromXDR(
  "AAAADgAAAA9IZWxsbywgU3RlbGxhciEA",
  "base64",
);
// Convert the ScVal to a string
const stringFromScVal = StellarSdk.scValToNative(myScVal);

# Convert the ScVal to a string
string_from_sc_val = stellar_sdk.scval.from_string("AAAADgAAAA9IZWxsbywgU3RlbGxhciEA").decode()
