Quadratic funding on Giveth — vote for Colibri with your donation

Small gifts from many people unlock extra matching from TheDAO Fund (Ethereum security round).

Core Tech for aTrustless Web3 Stack

Cryptographic proofs instead of trust: access Ethereum and EVM chains with answers you can verify in your own process—not on faith in a provider.

Don't trust. Verify! Always!

TheDAO Fund · Giveth

Quadratic funding for Ethereum security

A matching pool from TheDAO Fund is live on Giveth. Donations to eligible projects in this round receive extra impact from the pool—small contributions from many supporters weigh more than one large gift of the same total.

What is quadratic funding?

In quadratic funding, matching is driven by breadth of support, not only size. If many people each give a little, the matching algorithm allocates a disproportionately larger share of the pool—rewarding community signal and reducing dependence on whales.

If Colibri matters to you, consider a small donation and share the project link. Spreading the word helps others discover the round and improves matching for everyone building open, verifiable client infrastructure.

Sharing the project page helps others discover the round and improves matching.

Thank you for supporting colibri.stateless in this way — every small donation and every shared link helps us keep building verifiable client infrastructure for Ethereum and the EVM ecosystem.

Infrastructure

Our Products

Trustless blockchain access for any application. From verification to privacy to autonomous systems.

Core Verification Infrastructure

Colibri Stateless Client

Trustless Blockchain Access. With Built-in Privacy.

Colibri is a fully verifying stateless client for Ethereum and EVM-compatible chains. It enables applications to access and validate blockchain data locally using cryptographic proofs, without relying on trusted RPC providers.

Trustless verification of consensus and execution layer

No state sync required (stateless architecture)

Embedded privacy via Pragmatic Adaptive Privacy (PAP)

Local transaction simulation on verified state

Works in mobile, web, and IoT environments

Minimal bandwidth and resource requirements

Only Solution Combining All Three

Trustless verification

Stateless architecture

Integrated privacy

vRPC

RPC Responses You Can Verify.

Blockchain data together with cryptographic proofs. Drop-in replacement for traditional RPC while removing the need to trust infrastructure providers.

Drop-in replacement for traditional RPC

Proof-bound responses

No trust assumptions toward providers

Works with or without local Colibri client

Ecosystem

Built with Colibri

Applications and SDKs that bring Colibri's trustless verification model to real products — from image authenticity to private wallets and tokenized equity.

ColiCam

Android (Google Play) · iOS coming soon

Trust what you see.

The verification-first camera. Every image captured with ColiCam carries a cryptographic proof of its origin — device attestation, timestamp, and pixel-level hash — and is permanently registered onchain. Anyone can independently verify any image against the public registry. No servers, no intermediaries.

Cryptographic proof generated at capture — not after the fact
Onchain registration within seconds, immutable and publicly queryable
Independent verification without trusting any server or third party
Images never leave the device; only the proof is registered
