Cardano: get native script hash

Display native script components on Trezor, display the calculated native script hash and return the hash to the caller.

const result = await TrezorConnect.cardanoGetNativeScriptHash(params);

Params

Optional common params

CardanoGetNativeScriptHash type

• script — required CardanoNativeScript see description below.
• displayFormat — required CardanoNativeScriptHashDisplayFormat enum.
• derivationType — optional CardanoDerivationType enum. determines used derivation type. Default is set to ICARUS_TREZOR=2

CardanoNativeScript

CardanoNativeScript type

• type - required CardanoNativeScriptType/number.
• scripts — optional Array of nested CardanoNativeScripts.
• keyHash — optional string hex string of key hash. Used for CardanoScriptType.PUB_KEY.
• keyPath - optional string | Array<number> minimum length is 3. Used for CardanoScriptType.PUB_KEY.
• requiredSignaturesCount - optional string used for CardanoScriptType.N_OF_K.
• invalidBefore - optional string used for CardanoScriptType.INVALID_BEFORE.
• invalidHereafter - optional string used for CardanoScriptType.INVALID_HEREAFTER.

Example

Get native script hash of a simple PUB_KEY script:

TrezorConnect.cardanoGetNativeScriptHash({
    script: {
        type: CardanoNativeScriptType.PUB_KEY,
        keyHash: 'c4b9265645fde9536c0795adbcc5291767a0c61fd62448341d7e0386',
    },
    displayFormat: CardanoNativeScriptHashDisplayFormat.HIDE,
});

Get native script hash of a nested script:

TrezorConnect.cardanoGetAddress({
    script: {
        type: CardanoNativeScriptType.ALL,
        scripts: [
            {
                type: CardanoNativeScriptType.PUB_KEY,
                keyHash: 'c4b9265645fde9536c0795adbcc5291767a0c61fd62448341d7e0386',
            },
            {
                type: CardanoNativeScriptType.PUB_KEY,

            {

                scripts: [
                    {
                        type: CardanoNativeScriptType.PUB_KEY,

                    },
                    {
                        type: CardanoNativeScriptType.PUB_KEY,
                        keyHash: '0241f2d196f52a92fbd2183d03b370c30b6960cfdeae364ffabac889',
