Serializations
Serialization is how the value should be stringified for signing and for transfer between systems. Most serializations use outside standards, but some requiring additional clarifications are provided here.
decimal
Used to represent integers. Strings are used to avoid issues with different implementations of numbers.
- MUST use 0-9 representation
- MUST NOT have spaces or separators
- MUST be a string
| Invalid | Why | Valid |
|---|---|---|
0x123 | Must be decimal | "291" |
| 291 | Must be a string | "291" |
291n | BigInt(291) serialization appends an n | "291" |
hexadecimal
Used to represent bytes.
- MUST use 0-9 and a-f representation
- MUST be lowercase
- MUST be prefixed with a
0x - MUST NOT have spaces or separators
- MUST have two characters per byte in addition to the
0xcharacters
| Bytes | Invalid | Valid |
|---|---|---|
| 2 | 0x123 | 0x0123 |
| 2 | 123h | 0x0123 |
| 2 | 0x0ABC | 0x0abc |
| 8 | 0xabc | 0x0000000000000abc |
| 32 | 0x3e34c4325f4461b9355027b314f3eb56d31af549f7da7bd9ef1ce951651e | 0x00003e34c4325f4461b9355027b314f3eb56d31af549f7da7bd9ef1ce951651e |
