Wetìn Go Come Next for Private Smart Contracts for Midnight?

Midnight Foundation launch After Midnight on November 12 to show wetìn developers fit build after the Ledger 9 upgrade. The release allow one smart contract to call another inside one single transaction using unshielded data. During the premiere, the foundation announce one session for Discord to discuss how those calls fit handle private data for future release.

Wetìn developers fit build with Ledger 9

Jay Albert, solutions engineer for Midnight Foundation, use one collateralized loan take explain how contracts fit work together. Lending contract fit request asset price from another separate contract, check whether borrower get enough collateral, and approve the loan inside the same transaction. Albert still describe testing for one workflow wey vote go trigger treasury payout to the teams wey collect funding.

Contracts fit also emit events wey external applications fit watch. One software agent fit detect say vote pass and notify community for Discord or Telegram. The contract call dey execute one step inside the transaction, while the event dey give external application something to respond to. Both features first support unshielded data.

Ledger 9 still expand signature verification. Albert describe how one project fit distribute tokens for Midnight to eligible Ethereum asset holders. For him example, user go sign with their Ethereum wallet and prove say them hold qualifying asset to claim the distribution for Midnight. The application fit verify eligibility from another ecosystem while the signing key remain inside the user wallet.

Wetìn existing Midnight applications need update

Midnight move their mainnet go Ledger 9 on November 6. Contracts wey dem don deploy for mainnet carry over automatically, while applications wey dey interact with them need to move go Midnight.js 5. The upgrade documentation list Compact toolchain 0.36.0 to compile contracts wey target Ledger 9 and Wallet SDK 2.0.0 for wallet developers.

Albert still point one practical requirement for teams wey want make other applications fit call their contracts. Dem need to make the contract interface and the necessary build files available so other developers fit incorporate the call inside their own contracts.

The two test networks follow different upgrade paths. Preview relaunch as new chain on November 7, and Preprod upgrade in place on November 9, keep its transaction history and deployed contracts. Karmel, the foundation director of product, point developers go Preview to try the new features with test tokens.

How Midnight Passport go limit agent authority

Karmel link the Ledger 9 features to the upcoming Midnight Passport SDK, wey dem design to help users manage digital credentials and delegate tasks to software agents. During the Q&A, she explain one mechanism wey dem call scoped grants. User go define which actions agent fit take and fit revoke that permission. For agent wey dem authorize to trade, the grant go allow the user set limits on wetìn the agent fit do.

Karmel still discuss the Open Wallet Standard inside the context of managing permissions for actions on and off the network. She announce separate Passport presentation and plans to involve ecosystem members to test selected features. She highlight December as important month for Passport and no give specific release date for the SDK.
