amount |
BigInt | Amount to be issued. |
conf_amount |
boolean |
|
zei_params |
PublicParams | Public parameters necessary to generate asset records. |
# add_operation_air_assign(key_pair, user_public_key, issuer_public_key, commitment, pok-) → {TransactionBuilder}

# add_operation_create_asset(key_pair, memo, token_code, asset_rules) → {TransactionBuilder}
Wraps around TransactionBuilder to add an asset definition operation to a transaction builder instance.
Parameters:

|---|---|---|
key_pair |
XfrKeyPair | Issuer XfrKeyPair. |
memo |
string | Text field for asset definition. |
token_code |
string | Optional Base64 string representing the token code of the asset to be issued. If empty, a token code will be chosen at random. |
asset_rules |
AssetRules | Asset rules object specifying which simple policies apply to the asset. |
Example
Error handling
try {
await wasm.add_operation_create_asset(wasm.new_keypair(), "test_memo", wasm.random_asset_type(), wasm.AssetRules.default());
} catch (err) {
console.log(err)
