+# TORPC
+
+**TORPC (Token Optimized RPC) is an opt-in compression layer for blockchain JSON-RPC.** A client
+asks for a compression tier with one request header, and the server states the tier it actually
+applied with one response header. No new methods, no envelope, no new error codes, and no change to
+JSON-RPC 2.0 itself.
+
+JSON-RPC was designed for clients that render into an interface. A fast growing class of consumer is
+an LLM-driven agent that pays per token and has a finite context window. For that consumer most of a
+raw response is waste: hex padding, service fields it never reads, and undecoded calldata it cannot
+interpret. TORPC does that work once, on the way out.
+
+The specification is published under **CC0 1.0**, so anyone may implement it, and implementing it
+requires no permission from and no relationship with any provider.
+
+## Try it in one command
+
+Any endpoint that implements TORPC answers an ordinary JSON-RPC request. This one is public and
+needs no key:
+
+```bash
+curl -sS -i -X POST "https://rpc.ankr.com/monad_mainnet" \
+  -H 'Content-Type: application/json' \
+  -H 'Accept-Token-Tier: 2' \
+  -d '{"jsonrpc":"2.0","id":1,"method":"eth_getBlockByNumber","params":["latest",false]}'
+```
+
+The response carries `token-tier: 2`, and the body comes back renamed and in decimal:
+
+```json
+{"id":1,"jsonrpc":"2.0","result":{"base_fee_per_gas":"100000000000","block":"90785283",
+"gas_limit":"150000000","gas_used":"22917133","size":"800","timestamp":"1785159403"}}
+```
+
+## The documents
+
+| Document | What it is | Status |
+| --- | --- | --- |
+| [EVM RPC Compression v1](specs/evm-v1.md) | The normative specification | Draft. Tiers 1 and 2 normative, tiers 3 and above reserved |
+| [Per-method mappings](specs/methods/) | What each method's response becomes at each tier | 23 methods carry a v1 mapping, described by 8 documents |
+| [Conformance suite](https://github.com/w3tech/torpc/tree/main/conformance) | Golden cases an implementation must reproduce | Scaffold v0.0.1, one case. Not a coverage claim |
+| [Whitepaper](https://github.com/w3tech/torpc/tree/main/whitepaper) | Design rationale and measurements | Draft |
+| [Governance](GOVERNANCE.md) | How the specification changes | Current |
+| [Decisions](DECISIONS.md) | Why the design is what it is | Current |
+
+## Nobody is conformant yet
+
+The conformance suite holds exactly one golden case. Until it covers the specification, **no
+implementation, including Ankr's, may describe itself as TORPC conformant.** The word is reserved
+for something the suite can demonstrate.
+
+## Implementations
+
+- [w3tech/torpc-js](https://github.com/w3tech/torpc-js) is the reference decoder, the typed ruleset
+  and the benchmark harness, under Apache-2.0.
+- Ankr RPC applies tiers 1 and 2 on its endpoints. It is one implementation of this specification,
+  not the specification itself.
+
+Building another one? Open an issue in [w3tech/torpc](https://github.com/w3tech/torpc). Interop
+reports are the most useful thing the project can receive right now.
