Enterprise Addresses

Enterprise addresses contain only a payment credential, with no staking component.

Structure

Enterprise Address = Payment Credential Only

Payment Credential: Controls who can spend UTXOs at this address No Staking: Cannot delegate stake or earn staking rewards

Construction

Create enterprise addresses by instantiating the EnterpriseAddress class:

import { AddressEras, EnterpriseAddress, KeyHash } from "@evolution-sdk/evolution";

const address = new EnterpriseAddress.EnterpriseAddress({
  networkId: 1, // mainnet
  paymentCredential: new KeyHash.KeyHash({
    hash: new Uint8Array(28)
  })
});

const bech32 = AddressEras.toBech32(address);
console.log(bech32); // "addr1..."

Parsing Addresses

import { AddressEras, EnterpriseAddress } from "@evolution-sdk/evolution";

const bech32 = "addr1vx2kd28nq8ac5prwg32hhvudlwggpgfp8utlyqxu6wqgz6cevnrgl";

const address = AddressEras.fromBech32(bech32) as EnterpriseAddress.EnterpriseAddress;

console.log("Network ID:", address.networkId);
console.log("Payment:", address.paymentCredential);

Script-Based Example

Enterprise addresses can use script hashes as payment credentials:

import { AddressEras, EnterpriseAddress, ScriptHash } from "@evolution-sdk/evolution";

const scriptAddr = new EnterpriseAddress.EnterpriseAddress({
  networkId: 1,
  paymentCredential: new ScriptHash.ScriptHash({
    hash: new Uint8Array(28)
  })
});

const bech32 = AddressEras.toBech32(scriptAddr);
console.log("Script enterprise address:", bech32);

Format Details

Bech32 Prefix: addr (mainnet) or addr_test (testnet) Length: 29 bytes raw / ~59 characters Bech32 Header Bits: 0110xxxx (key hash) or 0111xxxx (script hash) Size Advantage: Half the size of base addresses (29 vs 57 bytes)

Comparison with Base Addresses

Feature	Enterprise	Base
Payment credential	Yes	Yes
Staking credential	No	Yes
Can receive funds	Yes	Yes
Can delegate stake	No	Yes
Earns staking rewards	No	Yes
Size	29 bytes	57 bytes
Use case	Exchanges, scripts	User wallets

Characteristics

Smaller Size: 29 bytes compared to 57 bytes for base addresses.

Single Credential: Only payment credential required - no stake key management.

No Staking: Cannot delegate stake or earn staking rewards.
