# Class: SolanaParser

Class for parsing arbitrary solana transactions in various formats
- by txHash
- from raw transaction data (base64 encoded or buffer)
- @solana/web3.js getTransaction().message object
- @solana/web3.js getParsedTransaction().message or Transaction.compileMessage() object
- @solana/web3.js TransactionInstruction object

## Constructors

### constructor

• **new SolanaParser**(`programInfos`, `parsers?`)

Initializes parser object
`SystemProgram`, `TokenProgram` and `AssociatedTokenProgram` are supported by default
but may be overriden by providing custom idl/custom parser

#### Parameters

| Name | Type | Description |
| :------ | :------ | :------ |
| `programInfos` | [`ProgramInfoType`](../interfaces/ProgramInfoType.md)[] | list of objects which contains programId and corresponding idl |
| `parsers?` | [`InstructionParserInfo`](../README.md#instructionparserinfo)[] | list of pairs (programId, custom parser) |

## Methods

### addParser

▸ **addParser**(`programId`, `parser`): `void`

| :------ | :------ | :------ |
| `programId` | `PublicKey` | program id to add parser for |
| `parser` | [`ParserFunction`](../README.md#parserfunction)<`Idl`, `string`\> | parser to parse programId instructions |

#### Returns

`void`

___

### addParserFromIdl
