@asentum/types

Shared TypeScript types and SSZ schemas for AsentumChain. Defines the canonical data shapes that the node, state, RPC, and SDK packages all agree on.

What's in here

• Primitives: Uint256, Uint64, Hash, Address SSZ schemas and constants (ADDRESS_BYTES, DILITHIUM3_PUBLIC_KEY_BYTES, etc.)
• Accounts: the on-chain account state type (balance, nonce, codeHash, storageRoot)
• Transactions: EIP-1559-flavored transaction body + signing envelope, with Dilithium3 public key and signature fields
• Blocks: block header and block schemas
• Helpers: emptyAccount(), emptyTransactionBody(), emptyBlockHeader() for tests and genesis

All schemas are defined using @chainsafe/ssz per decisions.md D17. Every type has both a runtime TypeScript shape and a canonical SSZ schema for deterministic encoding.

Usage

import {
  AccountSchema,
  emptyAccount,
  TransactionBodySchema,
  emptyTransactionBody,
  BlockSchema,
  emptyBlockHeader,
} from '@asentum/types';

// Create and serialize an account
const acct = { ...emptyAccount(), balance: 1_000_000_000_000_000_000n };
const bytes = AccountSchema.serialize(acct);

// Deserialize back
const restored = AccountSchema.deserialize(bytes);
