Inscriptions - Inscription Authority

Metaplex Inscriptions can have multiple update authorities. This is different to Metaplex NFT which can just have one update Authority plus delegates.

Authorities can be added and removed by each authority. An Inscription is seen as immutable as soon as no more update authorities exist.

Add Authorities

Additional Authorities can be added with a simple instruction call. One of the current Authorities has to sign the transaction.

Add an Authority

import {
  addAuthority,
  findInscriptionMetadataPda,
} from '@metaplex-foundation/mpl-inscription'

const inscriptionMetadataAccount = await findInscriptionMetadataPda(umi, {
  inscriptionAccount: inscriptionAccount.publicKey,
})

await addAuthority(umi, {
  inscriptionMetadataAccount,
  newAuthority: authority.publicKey,
}).sendAndConfirm(umi)

Remove Authority

To remove an authority there also is a instruction. removeAuthority allows you to remove yourself from the authority array. Be careful, as soon as you removed all authorities no authorities can be added anymore!

Remove yourself as authority

import {
  addAuthority,
  findInscriptionMetadataPda,
} from '@metaplex-foundation/mpl-inscription'

const inscriptionMetadataAccount = await findInscriptionMetadataPda(umi, {
  inscriptionAccount: inscriptionAccount.publicKey,
})

await removeAuthority(umi, {
  inscriptionMetadataAccount,
}).sendAndConfirm(umi)
