Encoding Utilities

##
Base58
source

ethers . utils . base58 . decode ( textData ) ⇒ Uin8Array

Return a typed Uint8Array representation of textData decoded using base-58 encoding.

ethers . utils . base58 . encode ( aBytesLike ) ⇒ string

Return aBytesLike encoded as a string using the base-58 encoding.

##
Base64

ethers . utils . base64 . decode ( textData ) ⇒ Uin8Array
source

Return a typed Uint8Array representation of textData decoded using base-64 encoding.

ethers . utils . base64 . encode ( aBytesLike ) ⇒ string
source

Return aBytesLike encoded as a string using the base-64 encoding.

##
Recursive-Length Prefix

The Recursive Length Prefix encoding is used throughout Ethereum to serialize nested structures of Arrays and data.

ethers . utils . RLP . encode ( dataObject ) ⇒ string<DataHexstring>
source

Encode a structured Data Object into its RLP-encoded representation.

Each Data component may be an valid BytesLike.

ethers . utils . RLP . decode ( aBytesLike ) ⇒ DataObject
source

Decode an RLP-encoded aBytesLike into its structured Data Object.

All Data components will be returned as a DataHexstring.

###
Data Object

A Data Object is a recursive structure which is used to serialize many internal structures in Ethereum. Each Data Object can either be:

- Binary Data
- An Array of Data Objects (i.e. this recursively includes Nesting)

Examples

- `"0x1234"`
- `[ "0x1234", [ "0xdead", "0xbeef" ], [ ] ]`
