Usage

const tx = { 
  chainId: 1n, 
  nonce: 0n, 
  maxFeePerGas: 100n, 
  maxPriorityFeePerGas: 1000n, 
  gasLimit: 1000n, 
  destination: "0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045", 
  amount: 100n, 
  data: new Uint8Array([1, 2, 3]),
  accessList: [{ address: "0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045", storage: ["0x00", "0x01"] }]
} as const

const utx = EIP1559UnsignedTransaction.from(tx)
const stx = utx.sign(key.sign(keccak256(utx.encode()))) // EIP1559SignedTransaction

const raw = stx.encode() // Uint8Array
const hex = `0x${raw.toHex()}` // 0x...

const stx2 = EIP1559SignedTransaction.decode(Uint8Array.fromHex(hex.slice(2)))
const utx2 = stx2.unsign() // EIP1559UnsignedTransaction
