Swap Your RPC: Hands-On Verified Reads, Simulation, and Privacy

Duration: NaN:NaN:NaN

Speaker: Simon Jentzsch

Type: Workshop

Expertise: Some familiarity with the topic

Event: Devcon

Date: Nov 2026

Every dApp trusts its RPC provider: it believes the balances, logs, and simulations the provider returns, and leaks the user's addresses and intent doing so. This workshop removes that trust — in the same interface your dApp already uses. You add colibri-stateless (an npm package) as a verifying EIP-1193 provider, then build up in small, observable steps: (1) verify account state and logs against the beacon-chain state root; (2) run a verified eth_call simulation locally and decode what a transaction would do before signing; (3) switch on privacy — request noise, multi-provider distribution — and watch what the provider can and cannot see. Join either path: tinker zero-setup in a hosted sandbox (play with config, inspect real proofs), or wire the provider into your own dApp and leave with a working integration. Prerequisites: JavaScript/TypeScript and basic Ethereum RPC. Everything runs client-side — no node to operate. You also get a clear view of the current limits.
