# Reference
Canonical reference for the Neo DevPack for Solidity. The pages below
are the source-of-truth tables you check when you need a definitive
answer about what's supported, what an error means, or how a Solidity
construct maps to NeoVM.
## Compiler & Language
- [EVM feature support matrix](/solidity/feature-support) — every
Solidity 0.8.x feature with its Neo support status (full / partial /
unsupported / lowered).
- [Language grammar](/language-description/grammar) — the formal
grammar accepted by `neo-solc`.
- [Cheatsheet](/language-description/cheatsheet) — quick-lookup for
syntax, operators, and globals.
- [Keyword index](/resources/keyword-index) — every reserved word and
built-in identifier with a link to its definition.
## Diagnostics & Errors
- [Error reference](/advisory-content/error-reference) — every
diagnostic the compiler emits, with cause and remediation.
- [Known bugs](/advisory-content/known-bugs) — currently-open issues.
- [Breaking changes](/advisory-content/breaking-changes) — version-to-version
migration notes.
## Runtime & VM
- [Runtime specification](/internals/runtime-specification) — the
semantics that compiled code relies on.
- [Native contracts](/internals/native-contracts) — every native Neo
contract with its method-by-method behavior.
- [Syscalls](/internals/syscalls) — full syscall catalog.
- [Architecture](/internals/architecture) — compiler + runtime layout.
- [NeoVM parity & limitations](/internals/parity-and-limitations) —
EVM constructs that don't have a clean NeoVM mapping.
## Standards & Mirror
- [Standards mirror — overview](/standards-mirror/) — entry point.
- [Coverage matrix](/standards-mirror/coverage-matrix) — every
mirrored ERC/EIP with category, status, mapping, and live deploy
state.
- [Coverage audit & gap report](/standards-mirror/coverage-audit) —
what's covered, what's missing, and the conventions used in the
Neo C# samples.
- [TestNet deployments](/standards-mirror/deployments/RESULTS) — 47
live ERC ↔ Neo pairs with addresses and assertion results.
- [Deferred deployments](/standards-mirror/deployments/DEFERRED) —
catalog-only entries with deferral rationale.
## Standards by Category
- [Token standards (NEP-11 / NEP-17)](/standards-mirror/tokens)
- [Account & authentication](/standards-mirror/account-and-auth)
- [Infrastructure & patterns](/standards-mirror/infrastructure)
- [DeFi building blocks](/standards-mirror/defi)
- [Protocol-level EIPs](/standards-mirror/protocol-eips)
- [Neo standards (NEP) reference](/additional-material/neo-standards)
## Other
- [Production readiness checklist](/advisory-content/production-readiness)
- [Use cases](/use-cases) — what's already shipped on Neo with this
compiler.
- [Common patterns](/resources/common-patterns) — idioms across token,
governance, and proxy standards.
