Developer Platform
Inscriptions
Metaplex introduced Inscriptions, a new standard for fully on-chain digital assets on Solana. Inscriptions enable users to store an asset’s metadata and media fully on Solana, removing external trust assumptions and unlocking greater composability for on-chain attributes and smart contracts.
Furthermore the Metaplex Inscription Gateway eliminates the need to use Arweave or IPFS for compatibility, enabling users to display on-chain data directly within dApps, wallets, and marketplaces. The gateway is Apache 2.0 licensed so anyone can run and use their own gateway. Security audits have been completed and both Inscriptions and the Inscription Gateway have been released to mainnet.
Engravings
Metaplex Engravings allow for Solana’s first truly immutable digital assets. The Engraver program adds an extra layer of security that prevents any changes from ever being made to Engraved NFTs, regardless of whether the originating program is immutable. This enables upgradeable Solana programs such as Token Metadata to create immutable digital assets while still preserving the ability to implement new features, bug/security fixes, and maintain compatibility with the ecosystem as it evolves. The Engraver program is not limited to just Inscriptions and can be used with traditional Metaplex NFTs as well.
The Engraver program is currently on devnet and is undergoing audits before being deployed to mainnet.
Token Extensions
Following the completion of the audit by Mad Shield, developers and creators can now mint assets with the Token22 token program through Metaplex. This includes the ability to mint fungible and non-fungible tokens using Token Extensions, alongside the benefits of building with Metaplex such as royalty enforcement, programmability, and ecosystem integration through Token Metadata.
Updating Compressed NFTs
Update Metadata for compressed NFTs is code-complete and was recently shipped to devnet following RPC activation.
This includes upgrades to Metaplex’s Bubblegum program and Digital Asset Standard (DAS) API, which is the reference implementation indexer and the API spec for interacting with digital assets on Solana.
