Tilt Development Environment
For a faster development cycle, especially when developing blockchain programs that interact with Wormhole contracts, consider setting up the Tilt Devnet Environment.
Tilt is a Kubernetes and Docker orchestration tool that will spin up all the Wormhole supported chains in containers, alongside a Guardian node that will observe and store VAAs.
This devnet environment can be set up on your computer or in a Linux VM that has at least 4 CPU cores and 16GB of RAM.
If you do decide to host the devnet in a remote VM, remember to pass in the host and webHost flags during the tilt up step and allow incoming traffic on your VM to be able to access the various RPC endpoints on the pods.
tilt up --host=0.0.0.0 -- --webHost=0.0.0.0
While the exact commands for each environment might differ, the basic setup process for Tilt is the following:
- Install Go
- Install Docker Desktop (Or Docker CE)
a. Install Minikube if Docker CE - Install Tilt
- Clone Wormhole Repo and Tilt Up
FAQ
Where are Fantom/Celo/Polygon/other EVM chains?
For all chains that support EVM, the smart contract development environment is effectively the same. For changes in gas costs and transaction times, consider testing contract logic on devnet and then using testnet environments to get chain-specific answers.
Solana is taking forever
Due to Solana's architecture, it often takes 25-40min to build the Solana pod. Consider increasing CPU cores assigned to devnet for a faster build.
Solana program deploy doesn't work
Kubernetes doesn't currently allow port forwarding for UDP ports, which is what Solana uses for solana program deploy. Instead, we recommend using Solana Deployer. Not only does this deploy programs over regular RPC (thus bypassing UDP port requirements), it's also much faster than solana program deploy.
Reset state for a pod
If you want to quickly iterate and don't want to bring Tilt down and back up, you can reset state for a pod by clicking the 🔄 button next to the pod name in Tilt UI.
