Developer Q&A

How do I get testnet coins? Ask /faucet in the Discord with your wallet address. It pays out a fixed, small amount, limited per day.

How do I write a Move package? thrylos move new myapp scaffolds one with a test. Then thrylos move test, thrylos move publish (builds first if needed), and thrylos move call. See Getting started and Writing Move on Thrylos.

Can my package remember anything? Yes. Values live in “drawers” keyed by an owner address and a slot number. Only the module that defines a type can store or take it — that’s what keeps one package from forging another’s data. Two working examples are in Examples.

What are the gas limits? A node currently accepts at most 20,000 gas for a call to a package (a temporary, node-local limit — the chain itself allows up to 75,000). An ordinary call uses tens to a few thousand. Gas is priced at about a microsecond of validator time per unit.

Can I read a value without paying for a transaction? thrylos move resource reads stored values for free, on any node. thrylos move view (calling a plain function without sending a transaction) needs a node with simulate turned on, which local networks have and the public testnet does not yet.

Will the testnet reset again? Yes, whenever a change needs it. Nothing on it should be treated as permanent — every balance, .thry name and published package is wiped each time.

Is there a token sale? No. See About Thrylos.

Where’s the code? github.com/thrylos-labs/thrylos-rust. The full technical spec is docs/spec.md in the repo.

Something’s broken or confusing — where do I say so? The Discord. Rough edges found this way get fixed; several already have.
