> Corpus Core builds trustless Web3 infrastructure. Colibri is a fully stateless Ethereum client (~200 kB) that verifies execution and consensus proofs locally — without running a full node or trusting RPC responses. Pragmatic Adaptive Privacy (PAP) adds adaptive read-path privacy (v2.0.0 ships PAP C1 Aggregation as MVP). v3.0 adds Glamsterdam support (new ZK consensus proof, light-client anchoring, Amsterdam EVM upgrade). Colibri targets wallets, multi-chain apps, AI agents, and constrained IoT / embedded devices.

## Company

- Name: Corpus Core (corpus.core)
- Focus: Stateless ethereum client, trustless light client, verifiable RPC (vRPC), Pragmatic Adaptive Privacy (PAP), Transaction Security Agent (TSA), IoT / embedded verification
- Motto: Don't trust. Verify.

## Primary pages

- Homepage: https://corpuscore.tech/ — company overview and product entry. Stack: colibri.stateless makes data trustless; vRPC is the infrastructure that serves it; PAP adds read privacy; the Transaction Security Agent explains a transaction on that foundation before signing.
- Colibri (stateless ethereum client): https://corpuscore.tech/colibri — product page for the verifier library
- Colibri developer docs: https://corpuscore.tech/colibri/developer — bindings (including Rust), quickstart, architecture
- Colibri sandbox: https://corpuscore.tech/colibri/sandbox — live WASM JSON-RPC demo
- vRPC (verifiable RPC): https://corpuscore.tech/vrpc — proof-bound RPC; local, prover service, and vRPC modes; call for provider collaboration
- Transaction Security Agent (TSA): https://corpuscore.tech/tsa — local SLM for Web3. Prototype that simulates a transaction on verified state and explains it with a local LLM in the browser before signing
- PAP (Pragmatic Adaptive Privacy): https://corpuscore.tech/pap — read-path privacy model
- Blog: https://corpuscore.tech/blog — Corpus Core Insights and release notes

## Ecosystem (built with Colibri)
