What's new?
Chiado is our new and improved testnet. Please make sure to transition all your testing and development processes here.
Key features
Chiado represents a crucial milestone in our journey towards mainnet launch. Here are the key features of the update:
The x/async module
The x/async Warden module runs offchain heavyweight computations asynchronously and stores the results onchain. It allows developers to build any logic combining offchain computation with onchain verification and enables smart contracts to leverage AI model outputs directly on the blockchain.
The module supports two types of computations: AI-driven price predictions and HTTP requests to external services, such as blockchain APIs.
Dual VM architecture
Chiado now supports EVM Solidity contracts alongside CosmWasm. This dual VM architecture makes it easier to integrate AI inferences with smart contracts, and users can connect directly to EVM apps.

Price feed oracles
Chiado introduces consensus-validated price feed oracles to Warden, ensuring reliable data essential to a vast range of DeFi applications.
Mainnet readiness
Chiado is prepared for real-world asset integration. As we transition to mainnet, developers will have a smooth experience bringing their projects from test environments into live deployments.
Key changes
When migrating ot Chiado, please keep in mind the following key changes:
New denomination
On Chiado, we've changed the denomination from uward to award.
A new signature scheme
To be EVM-compatible, keys on Chiado are generated with the ethermint.crypto.v1.ethsecp256k1 module, while Buenavista used cosmos.crypto.secp256k1.
EVM wallets support
We encourage users and application builders to store and delegate their test WARD with EVM wallets.
