Introduction

TON Devnet is a dedicated test network for the TON blockchain, intended for evaluating transactions, node behavior, and smart contract execution without the use of real funds. It replicates the architecture of the mainnet while adding several performance and scalability-related modifications, allowing testing in an environment that remains consistent with production behavior.

TON Devnet includes:

• a hybrid transport layer combining TCP and UDP;

• a direct intershard commit mechanism;

• an accelerated consensus protocol.

These components reduce latency, increase throughput, and simplify communication between validators.

Using TON Devnet, developers can:

• simulate network conditions;

• observe shard synchronization;

• validate intershard operations;

• test contracts with backward compatibility preserved.

TON Devnet provides a controlled environment for development, debugging, and verification before deploying to the mainnet.
