## Attachments
Encode attachments
```
const { AttachmentMSTTransfer } = require('./lib')
const attachment = new AttachmentMSTTransfer(
'MVS.HUG',
1,
)
console.log(attachment.toBuffer())
//
```
Decode attachments
```
console.log(Attachment.fromBuffer(Buffer.from('010000000200000002000000074d56532e4855470100000000000000', 'hex')))
// AttachmentMSTTransfer { type: 2, version: 1, symbol: 'MVS.HUG', quantity: 1 }
console.log(Attachment.fromBuffer(Buffer.from('01000000000000000', 'hex')))
// AttachmentETPTransfer { type: 0, version: 1 }
```
## Outputs
```
// decode from buffer
const output = Output.fromBuffer(Buffer.from('00e1f505000000001976a914e7da370944c15306b3809580110b0a6c653ac5a988ac0100000000000000', 'hex'))
// create ETP outputs
const etpOutput = new OutputETPTransfer('MGqHvbaH9wzdr6oUDFz4S1HptjoKQcjRve', 100000000)
// get json format
console.log(output.toJSON())
// {
// value: 100000000,
// script: 'OP_DUP OP_HASH160 [ e7da370944c15306b3809580110b0a6c653ac5a9 ] OP_EQUALVERIFY OP_CHECKSIG',
// attachment: AttachmentETPTransfer { type: 0, version: 1 }
// }
// encode output
console.log(etpOutput.toBuffer())
//
console.log(etpOutput.toString())
// 00e1f505000000001a1976a91461fde3bd4e6955c99b16de2d71e2a369888a1c0b88ac0100000000000000
