Full Pallet API Reference - v7.4 to v8.0

This page is a mechanically generated reference of every structural API change between Polymesh chain v7.4 and v8.0, extracted directly from each release's runtime metadata (metadata v14, the only version available for both releases). The v8 side reflects runtime version 8.0.1. It complements the narrative pages in the v7.4 → v8.0 changelog with a literal, pallet-by-pallet diff: every call, event, error, storage item, and constant that was added, removed, or had its argument/field shape change.

Scope and method:

• Comparison is by name, not by index. Call/event/error/storage indices are not stable across this upgrade (see the overview) and are ignored here entirely — an item that kept the same name and shape but moved to a different index is not listed as changed.
• "Modified" means the named item's argument names or underlying types changed. Cosmetic Rust-side renames introduced by the Polkadot SDK upgrade (for example T::BlockNumber becoming BlockNumberFor<T>) are resolved to their underlying structural type before comparing, so they are not flagged as modified when nothing observable actually changed.
• For constants, only a type change counts as "modified" — constant values (weight tables, fee coefficients, limits) are runtime tuning, not an API change, so value-only drift is not listed. The current value is still shown for reference, truncated if it's a long byte blob (e.g. a weight schedule).
• Pallets with no structural changes at all are omitted from the per-pallet detail below (they still appear as fully absent — nothing to migrate).
• The v7.4 / v8.0 columns show the Rust-level argument list or type signature, not the SCALE-encoded wire format.

Pallets added

Beefy, ConfidentialAssets (Testnet only), DidRegistrars, Mmr, MmrLeaf, MultiBlockMigrations, PolymeshTransactionPayment, Revive, Validators

Pallets removed

CddServiceProviders, Contracts, PolymeshContracts, RandomnessCollectiveFlip

The legacy Wasm/ink! contracts pallets Contracts (pallet-contracts) and PolymeshContracts (polymesh_contracts) are removed entirely; pallet-revive (listed under Pallets added) is the sole smart-contract pallet. See Smart Contracts.

Renamed pallets (for example CddServiceProviders → DidRegistrars) are not detected as renames by this name-based diff — they show up as one pallet removed and a different one added. See the Identity & Onboarding page for the narrative mapping.
