Communicate with over 10 blockchains
 with just a few lines of code.

Telegraph is a public permissionless cross-chain oracle empowering developers to easily access external blockchains from their smart contracts.


Current blockchain bridge node networks usually keep their systems behind registrations and approvals, stiffling developer innovation who are unable to scale their smart contracts.

Low barrier to entry

Add a few lines of code to your project to make it cross-chain without the need to register and download the full blockchain. With Telegraph, you can be relatively new to developing and without delay, start building.

a dynamic bridge

Telegraph nodes operate trustlessly, with all verification mechanisms occurring on each supported blockchain. We keep fees low where your smart contract users only have to pay the gas fees +$1

Instantly experience the brilliance of cross-chain by setting up and running a node on Telegraph in a minute. Join a global decentralized community that work together to support the network.

Telegraph tokens only come into existence as a result of a validated transaction, with each node being able to claim a share of all minted tokens. This equates to a fair and accountable means of distributing the tokens across participants within the Telegraph Ecosystem, while removing speculation as a driving factor.

Node Overview

How They Work?

Keeping it Simple
Telegraph nodes are lightweight programs that rely on the data provided by full nodes of blockchains. Each Telegraph node operates independently, but requires a threshold of signatures from its peers in order to initiate a transaction within telegraph smart contracts.
Nodes that complete transactions get rewarded with Telegraph tokens called $.

Why They Are Safe?

Thresholds & Time
Telegraph nodes & smart contracts have 2 primary means of validating authorized transaction requests: Signature thresholds and the time spent within the network.
A threshold of signatures representing a subset of the network must be sent to a Telegraph Smart contract.
That subset of signatures must represent a majority of time spent within the network.

Who Can Run A Node?

In the spirit of decentralization

Anyone can run a node and join the telegraph network. All participants must pay a fee in a token supported by Telegraph smart contracts.
