Project structure

contracts - source code of all the smart contracts of the project and their dependencies.
wrappers - wrapper classes (implementing Contract from ton-core) for the contracts, including any [de]serialization primitives and compilation functions.
tests - tests for the contracts.
scripts - scripts used by the project, mainly the deployment scripts.

How to use

Build

npx blueprint build or yarn blueprint build

Test

npx blueprint test or yarn blueprint test

Deploy or run another script

First, visit TON Center and register to get an API key to bypass rate limits. Replace <YOUR-API-KEY> with the API key you obtained from TON Center. <CUSTOM-TYPE> is either testnet or mainnet. <CHAIN-ID> is the chain ID of the chain you want to deploy to.

Then run:

CHAIN_ID=<CHAIN-ID> npx blueprint run --custom https://testnet.toncenter.com/api/v2/jsonRPC --custom-version v2 --custom-type <CUSTOM-TYPE> --custom-key <YOUR-API-KEY>

Add a new contract

npx blueprint create ContractName or yarn blueprint create ContractName

Important Note on Message Handling

When using the Pyth price feed in the recommended flow (User/App -> Pyth -> Protocol), be aware that:

Security Warning ⚠️

CRITICAL: Integrators MUST validate the sender address in their receive function to ensure messages are coming from the Pyth Oracle contract. Failure to do so could allow attackers to:

Send invalid price responses
Impersonate users via the sender_address and custom_payload fields
Potentially drain the protocol

Message Bouncing Behavior

If the target protocol bounces the message (e.g., due to invalid custom payload or other errors), the forwarded TON will remain in the Pyth contract and will not be automatically refunded to the original sender.
This could be significant when dealing with large amounts of TON (e.g., in DeFi operations).
Integrators should implement proper error handling and refund mechanisms in their applications.
