serializeAccessList

Serializes an EIP-2930 access list for RLP encoding

serializeAccessList

Serializes an EIP-2930 access list for RLP encoding. Validates addresses and storage keys before serialization.

Import

import "github.com/ChefBingbong/viem-go/utils/transaction"

Usage

import "github.com/ChefBingbong/viem-go/utils/transaction"


accessList := transaction.AccessList{
  {
      Address: "0x1234567890123456789012345678901234567890",
      StorageKeys: []string{
          "0x0000000000000000000000000000000000000000000000000000000000000001",
      },
  },
}


serialized, err := transaction.SerializeAccessList(accessList)
if err != nil {
  log.Fatal(err)
}
// serialized is []any for RLP encoding

Returns

  • Type: ([]any, error)

The serialized access list as an RLP-compatible slice. Each item is [address, [storageKey1, storageKey2, ...]].

Parameters

accessList (required)

  • Type: transaction.AccessList

The access list to serialize. Each item contains an address and storage keys.

accessList := transaction.AccessList{
  {
      Address: "0x1234567890123456789012345678901234567890",
      StorageKeys: []string{
          "0x0000000000000000000000000000000000000000000000000000000000000001",
      },
  },
}


serialized, _ := transaction.SerializeAccessList(accessList)

Address (required)

  • Type: string

The contract address. Must be a valid 40-character hex address with 0x prefix.

item := transaction.AccessListItem{
  Address: "0x1234567890123456789012345678901234567890",
  StorageKeys: []string{...},
}

StorageKeys (required)

  • Type: []string

The storage keys to access. Each key must be exactly 32 bytes (64 hex characters with 0x prefix).

item := transaction.AccessListItem{
  Address: "0x1234567890123456789012345678901234567890",
  StorageKeys: []string{
      "0x0000000000000000000000000000000000000000000000000000000000000001",
      "0x0000000000000000000000000000000000000000000000000000000000000002",
  },
}

Serialized Format

The serialized access list format is:

[
  [address1, [storageKey1, storageKey2, ...]],
  [address2, [storageKey3, ...]],
  ...
]

ParseAccessList

To parse an RLP-decoded access list back to AccessList:

parsed, _ := transaction.ParseAccessList(rlpDecodedData)

Validations

This function validates:

  1. Address Format: Each address must be a valid 40-character hex address
  2. Storage Key Size: Each storage key must be exactly 32 bytes (64 hex characters)
