•BigDecimal: Large decimal numbers with 18 decimal places

3. Encode Custom Types

Select "Custom Type" to encode complex structures:

Vector Example:

// Type Definition

vector<u64>

// Input Value

[1, 2, 3, 4, 5]

Struct Example:

// Type Definition

struct ABC { a: u64, b: string }

// Input Value

{"a": 100, "b": "hello"}

Option Example:

// Type Definition

option<u64>

// Input Value (Some)

123

// Input Value (None)

null

4. Choose Output Format

Select your preferred encoding format:

•Hexadecimal: Standard hex format (e.g., 0a1b2c)
•Base64: Base64 encoded string
•Base58: Base58 encoded string

About BCS Encoding

Binary Canonical Serialization (BCS) is the serialization format used in Move-based blockchains. It provides a deterministic way to serialize data structures into binary format.
